Introduction

The kV/kV2 MODBUS Communications Board

is an optional factory-supplied addition to the

kV or kV2Meter, or may be ordered in theform of a retrofit kit to upgrade Communication

Ready kV Meters or kV2 Meters. KV

Meters that are capable of being upgraded may be

identified by the words Modem Ready on theupper nameplate of the meter.

The kV/kV2 MODBUS Option Board is used toprovide two-way communication to the kV or

kV2 Meter and may be used on S-base, A-

base, and switchboard meters. It is available only

on Demand/LP or TOU version of the kV orkV2 Meter.

The kV/kV2 MODBUS Option Board may be

used in conjunction with other GE option boards,

which provide a three-phase power supply, loadprofile recording (kV only), and input/output

functions. If required, the flexibility of the kV

and kV2 Meters makes it possible to combineup to 3 option boards in a single meter.

RS-485/MODBUS provides a half-duplex, 2 -

wire, RS-485 interface for remote reading of the

kV/kV2 Meter. The baud rate is fixed at 19200

bps.

All kV Meters, including those with kV/kV2

MODBUS boards, are programmed using GEsMeterMate software program.

kV/kV2 MODBUSFeatures

The kV/kV2 MODBUS Option Board provides a

means of remotely reading the kV/kV2 Meter

over an electrically isolated, twisted pair, half-

duplex, RS-485 link. The kV/kV2 MODBUScontains only two programmable features,

discussed in more detail below.

MODBUS Device Address

The MODBUS board is delivered with a default

address of 15 (0x0F). Prior to installation into asystem, each device must be programmed with a

unique address. Refer to Appendix A, Register

Maps for the appropriate register address.

The MODBUS board must be programmed with a

password that matches that of the meter on whichit is installed. All MODBUS boards have a

default password of MASTER_012. It is

recommended that this same password beprogrammed into the meter on which the board is

installed. If a different password is desired, the

meter must be programmed with the desired

password using MeterMate software. TheMODBUS board must be set with the desired

password using the MODBUS interface. Refer to

Appendix A, Register Maps, for the appropriate

register address.

Data Rate

The kV/kV2 MODBUS Option is configured for

8 data bits, 1 stop bit, no parity, and a fixed baud

rate of 19200bps.

Installing the kV/kV2MODBUS in the kV orkV2 Meter

Warning: The kV/kV2 Metercontains lethal voltages. The meter must

be completely disconnected from any

external circuits and the carryovercapacitor completely discharged before

disassembly is attempted. Failure to

observe this practice can result inserious injury or death. For more

information refer to the appropriate

meter instruction book.

kV/kV2 MODBUS Installation

The kV/kV2 MODBUS Option Board can only be

installed in Modem Ready kV Meters. Thesemeters can be identified by the words Modem

Ready which are printed on the left side of the

meter nameplate. All kV2 meters are modemready.

Any combination of up to three (3) option boards

may be installed in the kV/ kV2 Meter at one

time. These include the I/O-2 Input/Output optionboard, the MIO Multi-Input/Output option board

Page 5

7/28/2019 GEH-7282

7/55

(kV2 only), the LP-2 Load Profile option board

(kV only), the kV/kV2 MODBUS Option Board,

and the RG-1 Revenue Guard option board. The

I/O-2 (or MIO), LP-2, and kV/kV2 MODBUS

Option Board can be combined in an option boardstack if necessary. See Figure 1 for details.

Figure 1: Option board stack

The Revenue Guard option board is not part of

this stack and is not affected by the presence of

other option boards.

All MODBUS boards are shipped with an RJ-11

cable connector. This connector will typically

need to be removed and replaced with a connectorappropriate for the network in which the

MODBUS meter will be installed. Appendix C

contains a wiring diagram to facilitate thisprocedure.

The kV/kV2 MODBUS board is installed asfollows:

1. If the meter is not disassembled, follow the

disassembly instructions described in the

appropriate meter instruction book.

2. Place the bezel face down on a soft, cleansurface to protect the nameplate and liquid

crystal display.

3. Remove the I/O (or MIO) and LP option

boards if they are present.

4. The I/O-1 and LP-1 option boards must notbe reused with the kV/kV2 MODBUS

board.

5. If the kV/kV2 MODBUS Option Board will

not be combined with either the I/O or LP

option boards proceed to step 9. If the

kV/kV2 MODBUS Option Board will be

installed with the I/O-2 and/or LP-2 option

boards proceed to the next step.

6. Place the kV/kV2 MODBUS Option Boardon a soft clean surface and install the four

(4) nylon spacers by gently pushing theminto the four (4) holes on the board.

Do not reuse nylon spacers. When

removed, a slight rounding of the spacer

occurs which can greatly decrease the

ability of the spacer to hold the option

board firmly in place.

7. If both the LP-2 and I/0-2 option boards areto be installed, the LP-2 option board must

be installed next. Install it by engaging the

26 pin connector pins between the kV/kV2

MODBUS Option Board and the LP-2

option board. Then, after lining up the nylonspacers on the kV/kV2 MODBUS Option

Board with the four (4) holes on the LP-2

board, snap the option board into place.

8. The I/O-2 option board may be installed

directly to the kV/kV2 MODBUS Option

Board if the LP-2 option board will not be

used or, it may be installed directly to the

LP-2 option board. Either way, the I/O-2

option board is installed in a similar mannerto the LP-2 option board described in step 6

above.

Note: The kV/kV2 MODBUS Option Boardmust always be installed as the inner mostoption board (the board closest to theMeters main board).

9. Depending on whether the installation isbeing made to an S-base or A-base meter,

install the appropriate cable assembly as

described below. For installation on a

switchboard kV/kV2 Meter, refer to the

switchboard meter instruction book, GEH-7271.

Installation on S-base Meters

While the meter is unassembled, the S-basecommunications cable assembly must be

installed. This cable assembly is installed in S-

base meters as follows:

1. With the kV Meter base facing you, locate

the lower of the two small knockouts andremove it (see Figure 6: Locating knockout

for cable assembly on S-Base meters).

Enlarge the hole to a diameter of 0.290inches. Make sure the resulting hole is

clean.

Page 6

7/28/2019 GEH-7282

2. Locate the end of the cable assembly with

the two small black connectors. Pass the

larger of the black connectors through the

knockout hole from the back side of the

meter base. Next, pass the smaller blackconnector through the same hole and pull

until the wire tie is in the slot and up against

the base. Make sure that the cable has beenbrought up on the outside of the shroud.

Figure 6: Locating knockout for cableassembly on S-Base meters

3. Check the headers on the kV/kV2MODBUS board to make sure that the pins

are not bent or out of position. Orient the

smallest black connector such that the

indexed (filled) hole in the black connectoris lined up with the missing pin in the 4 pin

header. Plug the connector assembly into

the header on the MODBUS board. Orient

the larger black connector such that theindexed (filled) hole in the black connector

is lined up with the missing pin in the 6 pin

header. Plug the connector assembly intothe header on the MODBUS board.

4. Attach the plastic connector holder as shownin Figure 7. The connector holder snaps

should extend through the holes in the

kV/kV2 MODBUS board and snap intoplace.

5. Check the 30 pin header on the meter board

to make sure that the pins are not bent or out

of position. Adjust any pins that are out of

alignment.

kV Meters with 26 pin headersinstead of 30 pin headers cannot be

retrofitted with the kV/kV2 MODBUSOption Board .

Figure 7 : Connector holder placement

6. With the kV/kV2 MODBUS Option Board

stack in hand, insert the tabs on thekV/kV2 MODBUS Option Board into theslots in the bezel (see figure 8).

Figure 8: Inserting option boards

7. Gently lower the board until the 30 pin

connector on the meter and the kV/kV2

MODBUS Option Board are engaged. Makesure that the two snaps engage the board.

8. Reassemble the meter, except for the cover,as described in the kV or kV2 Meter

instruction book. Insert and tighten a wire tiearound the cable assembly on the inside of

the meter base to retain the cable assembly.

9. Place the special label indicating the presence

of MODBUS communications on the side of

the meter shroud and replace the cover. SeeFigure .

Figure 9 : Check "RS" box

Installation on A-base Meters

While the meter is unassembled, the A-basecommunications cable assembly must be

installed. This cable assembly is installed in A-

base meters as follows:

1. With the Meter base facing you, locate the

knockout on the left side of the base (see

Figure 10) and remove it by tapping it with apunch. Make sure the hole is clean and the

knockout parts are removed.

Figure 10: Locating knockout for cableassembly on A-Base meters

2. Insert the small connectors end of the cableassembly through the knockout from theoutside of the meter base until the grommet

contacts the knockout. Make sure that the

cable has been brought up on the outside ofthe shroud.

3. Insert the grommet into the knockout and

push until the grommet is fully seated.

4. Check the headers on the kV/kV2

MODBUS board to make sure that the pins

are not bent or out of position. Orient the

smallest black connector such that the

indexed (filled) hole in the black connectoris lined up with the missing pin in the 4 pin

header. Plug the connector assembly into

the header on the MODBUS board. Orientthe larger black connector such that the

indexed (filled) hole in the black connector

is lined up with the missing pin in the 6 pin

header. Plug the connector assembly intothe header on the MODBUS board.

5. Attach the plastic connector holder as shown

in Figure 7. The connector holder snaps

should extend through the holes in thekV/kV2 MODBUS board and snap into

place.

6. Follow the steps outlined in the S base

installation for inserting the stack into themeter. Then, reassemble the meter.

7. Place the special label indicating thepresence of MODBUS communications on

the side of the meter shroud and replace the

cover. See Figure .

MeterMate SoftwareCompatibility

The kV/kV2 MODBUS Option Board iscompatible with the following software:

MeterMate Version 2.12 or greater. Note that

this software will ignore the MODBUS board.

There are restrictions on the way a kV/kV2 meter

must be programmed in order to operate correctly

with the MODBUS board. See Appendix C for

details.

Meter Installation

The kV/kV2 Meter must be connected to theexternal communications device through a means

which will provide both a secure connection and

ease of disconnection for troubleshooting, meter

change out, etc.

All kV/kV2 Meters with kV/kV2 MODBUS

option are supplied with an insulatedcommunications cable which extends

approximately 30 inches out the base on S-base

meters and out of the side of the case on A-basemeters. The communications cable will be

terminated in an RJ-11, which may be replaced by

the required connector following the wiring

diagram shown in Appendix B.

The communications cable should exit the S-base

meter socket enclosure by the most direct means

and be connected to the customer providedcommunications equipment external to the meter

enclosure. Usual practice has a short conduit

nipple extending from the meter enclosure to aseparate, dedicated enclosure where the external

modem is located.

Important: Under no condition should

the communications line be run in a conduit

with power lines or exit the meter enclosure

via the same nipple as the power lines. Also,

for the case where other optional signal lines

are taken from the kV/kV2 Meter, these

other lines should not be bundled with either

the power lines or the phone line.

For A-base meters, the connection to the

customer supplied communications equipmentshould be done in a similar manner. The

communications cable for the A-base terminalblock should be taken immediately to a separate

enclosure dedicated to this specific application.

Figure 14: kV/kV2 MODBUS LED location

An LED will illuminate when the kV/kV2Meters MODBUS board is powered up. The

LED will flash for approximately 15 seconds.During this period, communications is not

possible. Immediately after the LED stops

flashing, the meter display should briefly indicate

busy as the MODBUS board reads basic

information from the meter. The LED will alsolight each time the MODBUS board has

established communications with the meter for

the purposes of acquiring data. By monitoring thisLED (as well as any LEDs on the external

modem), correct operation of the kV/kV2

MODBUS board can be verified during meterinstallation.

Renewal Parts

kV/kV2 MODBUS Kits

There are two kV/kV2 MODBUS kits that maybe ordered to retrofit a Modem ready kV

Meter or a kV2. Modem ready kV Meters

will have Modem Ready printed on the meter

nameplate. If the kV Meter nameplate does not

have this designation, the meter cannot be

retrofitted with a kV/kV2 MODBUS board.Any kV2 meter can be retrofitted with a

MODBUS board.

Appendix A MODBUS Operation

Commands Supported

The MODBUS protocol specification can be obtained by visiting the Website http://www.modbus.org/default.htm.

The kV/kV2 MODBUS board supports a subset of the standard MODBUS commands. These are:

0x03 Read Holding Registers

0x04 Read Input Registers

0x06 Preset Single Register0x16 Preset Multiple Registers

Password and Data Access

The kV/kV2 meters do not, by themselves, support MODBUS; the native protocol for these meters is PSEM (ANSIC12.18) and AMRA Tables (ANSI C12.19). Consequently, the MODBUS board must convert MODBUS requeststo PSEM requests in order to retrieve data from the meter. Meter responses must be translated back to MODBUS

protocol before they are transmitted back to the MODBUS host. This operation is transparent to the MODBUS user

and the information is provided only as background. KV/kV2 meters are generally password-protected. In order for

the MODBUS board to retrieve meter data, it must know the meter password. MODBUS boards are shipped from

the factory with a default meter password of MASTER_012. This is stored in the MODBUS board as theequivalent sequence of hexadecimal digits. GE recommends that the user program the same password into the

meter. However, if the user wants to use a different password, it may be changed in the meter using the GE

programming software (MeterMate) and then must also be changed in the MODBUS board by writing the desiredpassword to the sequence of registers reserved for same (see register maps).

The set of data available through the MODBUS interface is a subset of the data contained in the meter(s) and

accessible through the PSEM interface. In addition, in order to gain access to the full set of MODBUS registers

listed in Appendix B, some of the meter parameters must always be programmed with predetermined, fixed values.If these fixed programming parameters are changed, behavior of the MODBUS interface is undetermined.

MODBUS Address

The MODBUS board is shipped with a default MODBUS address of 15 (0x0F). Note that a full, two-byte register is

reserved for the address; however, only the low-order byte is actually used. Each device must be assigned a newaddress that is unique for the network in which it will be installed. Valid addresses may be from 1 to 247; all other

values are reserved. The MODBUS board recognizes the universal address of 0x00. This address may be used to

communicate with individual MODBUS devices in the event that the individual address is lost or forgotten. In order

to reset the individual MODBUS address, the device must be the only one in the communication path. Then amessage can be addressed to the universal address (0x00) to tell the device to set its individual address to the desired

value. The user should then verify that the device will respond to its new address before installing it in the larger

network with other MODBUS devices.

Accessing the Data Log

Data log information may be retrieved an interval at a time. The default configuration for the interval length is 15

minutes. In general, the host system will poll the meter at regular intervals to obtain the most recent data log interval

Page 13

7/28/2019 GEH-7282

15/55

and the host software will keep track of the last interval read. The MODBUS board keeps track of the most recent

interval recorded; this is available in register 0x2802.

In order to retrieve a specific interval from the data log, the host software must first write the number of the desired

interval into the Data Log Interval Selector register (0x2801). Intervals are numbered from 1 to 2880, therebyproviding up to 30 days of 15-minute interval data. Fewer intervals will be available when fewer than 30 days have

elapsed since recording began.

When the MODBUS board has successfully transferred this interval data from the meter into its own buffers, it will

update the Data Log Last Read register (0x2800) to indicate that the data is now available. The host software can

then retrieve the data by reading the desired number of channels beginning at register 0x2807.

Network Architecture and Wiring

Modbus Wiring Rules Diagrams

The Modbus network protocol has wiring rules and limits on the number of IEDs that may be attached.This section describes in greater detail the rules you must follow when designing a Modbus network.

NOTE: It is important to take future expandability

into consideration when designing a network

configuration. This is particularly so when thenetwork is near its maximum number of IEDs or

maximum cable length. Adding IEDs to a networkafter it has been installed may require rewiring the

network.

CAUTION: Wire-run distances mentioned in the

configuration rules assume application above grade

or in conduit. For below-grade applications, refer toSection 31, Wiring Requirements.

Regardless of which platform is supporting the RS-485 networks (Ethernet Gateway, RS-485 card, or RS-232/RS-

485 converter), the following rules apply to each individual RS-485 network.

1. Each RS-485 network may support up to 31 Modbus IEDs. Figure 2 illustrates this rule. (See the exception

below Figure 6.)

31 RS-485 IEDs maximum;

PMCS Host PC, Ethernet Gateway or MSP

always located at one end of Modbus network.

Host

Figure 2. Network illustrating Modbus Rules 1 and 2.

Exception to Rule 1: Some types of IEDs must be wired on dedicated private serial network segments, one IED per

serial Modbus line.

2. The host (or Ethernet Gateway) must always be located at one end of any Modbus segment. It may not belocated in the center of a Modbus network. Figure 2 shows the correct placement of the host (PC or Ethernet

Gateway).

3. All Modbus IEDs on a single RS-485 network must communicate at the same baud rate. If IEDs with different

communication speeds are connected to the same RS-485 network, the whole segment will communicate at thespeed of the slowest IED. Figure 3 illustrates this rule. (Communication speeds for supported IEDs are listed in

Table 1.)

Page 44

7/28/2019 GEH-7282

46/55

Figure 3. Network illustrating Modbus Rule 3.

4. Each RS-485 network must be properly terminated at both ends of the cable run after the final IED. Figure 4

illustrates this rule.5. Each RS-485 network must have its shield properly grounded. Figure 4 illustrates proper RS-485 wiring and

grounding.

CAUTION: Improper grounding may create aground-loop condition and cause communications

failures. Make sure you follow the wiring diagram

carefully.

To ensure proper grounding, follow this procedure. Begin by grounding the RS-485 cable shield at the host. Follow

the cable to the first IED on the network. Do NOT connect the cable ground to the IED. Pick up the RS-485 output

cable from the IED and attach its ground to the IEDs shield connection or grounding screw. For IEDs with nogrounding connectors, connect to earth ground.

Follow the cable to the next IED, and repeat the above procedure. Do not connect the RS-485 shield from the

previous IED, but DO connect the RS-485 OUT shield on its way to the next IED.

EXCEPTION: The Multilin 565 Feeder

Management Relay does not have isolated

communications ports. Do NOT connect the shield at

this IED. Instead connect the shield of the incomingRS-485 cable to the shield of the outgoing RS-485

cable, skipping the Multilin 565.

Rules of thumb: RS-485 cable ground should always be connected at the previous IED, never upon arrival at an

IED. All RS-485 IEDs must have either two communications cables attached or one communications cable and a

terminating resistor.

Network Wiring and Construction

Once the network has been carefully laid out on paper and IED addresses have been planned, you need to check the

following wiring requirements before beginning assembly of the system.

WARNING: Network wiring and grounding rules described herein apply primarily to commeand industrial installations. Substation installations will exist in the presence of dangerously

elevated ground potential relative to points outside of the station grid as well as large

electromagnetic induction fields. Additionally, large ground faults can elevate substation groupotentials. Follow local utility best-practices and safety procedures to prevent risk of shock or

electrocution to personnel and damage to equipment that could result in a loss of protection a

communications.

CAUTION: The recommended installation practice is to implement optical fiber for connecti

between buildings to provide electrical isolation. This eliminates harmful ground loops cause

differences in the ground potential between structures.

CAUTION: Data line surge protection is recommended for network components such as hubscomputers, or modems connected to IEDs with copper wire, especially installations where the

data communication cable is exposed (i.e., not encased in conduit) or runs parallel to power

conductors. IEDs are routinely installed in areas exposed to heavy electromagnetic fields (EM

which can induce damaging surges in data communication lines. Data line surge protection is

required for fiber optic connections.

Page 48

Wiring Requirements

Modbus has unique wiring requirements. These rules are summarized following.

WARNING: The National Electrical Code (NEC)

and all applicable local codes must be followedwhen installing wiring.

Type of Wire

Belden 9841 or Alpha 6412 may be used for applications under 300 V that are indoors or outdoors in conduit above

grade. These cables may be also be used for 600 V requirements by applying 600 V tubing to them. Belden 3074F

may be used for applications greater than 300 V which are indoors or outdoors in conduit above grade.

Termination

RS-485 cables must be terminated at each end of the network with a 120-ohm, 1/2-watt, 5% tolerance resistor.

IMPORTANT NOTE FOR CONNECT TECH

CARD USERS: The Connect Tech RS-485 cardrequires a 600-ohm rather than a 120-ohm resistor.

Use the 600-ohm resistor at the Connect Tech card

only. The other end of the Modbus network(s)

should be terminated with the usual 120-ohm

resistor.

See Figure 4 for an example of the cable run terminated at the final IED on the network.

Shield Grounding

The RS-485 cable shield must be grounded at only a single point on each RS-485 wire. Connect the shield to the

ground terminal at the Ethernet Gateway or RS-485 interface card. Connect the cable shield to the shield terminal ateach IED on the RS-485 network except the Multilin 565, which does not have isolated communication ports

(Modbus Rule 5, Section 24).

Page 49

7/28/2019 GEH-7282

51/55

Local Configuration of IEDs

You must properly configure each IED connected to the host software. Be sure to set the IED address at the IED and

at the host software, set the communication speed, and configure any necessary settings.

For detailed directions on setting addresses, communication speed, and protection parameters, refer to the user guide

for each IED.

Applying Power to the System

WARNING:

Voltages hazardous to personnel and equipment may be present at the power connections.

Once youve installed the network, you should apply power to the network from the bottom up. Follow thisprocedure when applying power to the system for the first time:

1. Make sure that all communications wiring has been correctly connected to each IED and that the systemmatches the plan exactly, meeting all rules and requirements explained in this manual.

2. Make sure that all wiring for control power to IEDs has been correctly installed and that the correct controlvoltage is present at each IED.

3. If commnet IEDs are installed, apply control power to the IEDs and then to the Modbus Concentrator to which

they are attached.4. Apply control power to any Modbus RTU IEDs.

5. Apply control power to the Ethernet Gateway, if one is being used.

6. Turn the computer on and start the host software according to the instructions in the software manuals.

Trouble-Shooting Guide

Symptom Possible Cause Corrective Action

1. No communication to one

or more Modbus IEDs;

some IEDs OK.

The IED or a repeater is not

powered.

Check that control power is supplied to all IEDs and

repeaters. If the IED or repeater does not operate when

control power is present, contact the GE Resolution Center

at 1-888-GE-RESOLV.

RS-485 wiring is shorted orimproperly connected.

Locate and remove the short or incorrect connection.

An RS-485 shield has been

grounded incorrectly.

Refer to Section 24, Rule 5 for proper RS-485 grounding

considerations. Recheck the RS-485 network forcompliance. Improper grounding can cause communication

errors.

The network configuration is

incorrect.

Check that the network conforms to rules regarding RS-485

wiring above.The IED is not addressed. Ensure that each IEDs Modbus address corresponds to the

address set at the host software.

Two or more Modbus IEDs

have the same address.

Check IEDs for duplicate address assignments. Change the

address of the affected IED, then attempt to communicate

with the original address to see if another IED has thataddress.

Check any dual-port IEDs to be sure that each RS-485 portis wired to a separate RS-485 network.

2. No communication to anyIEDs on one commnet

segment.

The IEDs or a Repeater on thatsegment is not powered.

Check that control power is supplied to all IEDs. Checkthat two LEDs are lit on each Repeater, indicating that

control power is present. If the IED or Repeater does not

operate when control power is present, contact the GE

Resolution Center at 1-888-GE-RESOLV.Commnet wires are shorted or

improperly connected.

Locate and remove the short or incorrect connection.

The network configuration of

the segment is incorrect.

Check that the segment conforms to Rules 1 through 5 in

Chapter 2 regarding the number of IEDs permitted percommnet segment and wiring requirements and limitations.

3. Intermittent communi-

cation to an IED (Modbus

or commnet).

The network configuration is

incorrect.

Check that the network conforms to the rules in Chapter 2.

The IED or a Repeater is notpowered or has inconsistent

power.

Check the control power supplied to the IED and to anyRepeaters on the network or segment.

Two or more IEDs on thenetwork have the same address.

Check the host for duplicate address assignments. Changethe address of the affected IED, then attempt to

communicate with the original address to see if another

IED has that address.
