Section 1—Micrologic Communication System

Introduction The Modbus communication option makes it possible to remotely use all the

functions of a MasterPact™, PowerPact™, or Compact™ circuit breaker, its Micrologic trip unit, and all its options.

Remote operations are based on a secure communication architecture. The Modbus communication system may be used to interconnect the control units (A, P, or H) and a supervisor, and a PLC or Modbus master. The connection uses an RS485 physical link and the Modbus-RTU protocol.

Communication System Parameters

Micrologic trip units use a system consisting of:

• 4-wire Modbus,

• RTU, RS485 network,

• master / slave (Micrologic trip units are always slaves),

• any Modbus software (not proprietary),

• daisy chain using Belden

recommended).

Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 0613IB1201 Section 1—Micrologic Communication System 06/2012

Communication System Components

Circuit breakers that have Micrologic trip units are Powerpact, Compact, and Masterpact.

The communication system consists of:

• Micrologic trip units (A, P, or H models are capable of communication),

• Breaker Communication Module (BCM),

• communication switches that report circuit breaker status (open, closed,

tripped, ready to close) into the BCM,

• 24 Vdc control power,

• daisy chain 4-wire Modbus network,

• drawout circuit breakers also have cradle communication module

(CCM),

• communicating shunt trip and shunt close coils,

• ethernet gateway or circuit monitor to allow Modbus TCP / IP

communication.

Micrologic A Trip Units • Trip units require 50 mA at 24 Vdc control power. Control power source

to the trip unit must be isolated from the 24 Vdc control power to the BCM. The positive or negative output of the power supply must not be earth grounded. The DC output of the 24 Vdc power supply must also be isolated from its input. See External 24 Vdc Control Power Supply Characteristics on 11.

• Micrologic A trip units control power connections to F1 (-) and F2 (+).

• See the trip unit manual and the Masterpact NT/NW Universal Power

Circuit Breakers catalog for specific information about the trip unit and other components.

Micrologic P and H Trip Units • Micrologic P or H trip units require 100 mA at 24 Vdc control power.

Control power source to the trip unit must be isolated from the 24 Vdc control power to the BCM. The positive or negative output of the power supply must not be earth grounded. The DC output of the 24 Vdc power supply must also be isolated from its input. See External 24 Vdc Control Power Supply Characteristics on 11.

• P and H trip units control power connections to F1 (-) and F2 (+).

• See the trip unit manual and the Masterpact NT/NW Universal Power

Circuit Breakers catalog for specific information about the trip unit and other components.

Breaker Communication Module (BCM) • The BCM requires 50 mA at 24 Vdc control power. Control power source

• The BCM control power connections to E1 (+) and E2 (-).

Communication Switches • Report circuit breaker status into BCM. Switches are actuated by the

circuit breaker mechanism to indicate open, closed, tripped, and ready to close status.

• Switches are installed in the circuit breaker mechanism and connected

by wiring and connector into the BCM.

• See BCM instructions for each circuit breaker type for instructions and

mounting information.

0613IB1201 Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 06/2012 Section 1—Micrologic Communication System

24 Vdc Control Power • The 24 Vdc (E1, E2) power supply for the BCM must be separate from

the 24 Vdc power supply module for the Micrologic trip units (F1-, F2+).

• The separate power supplies provide isolation between the trip unit and

the communication system. The positive or negative output of the power

supply must not be earth grounded. The DC output of the 24 Vdc power

supply must also be isolated from its input. Specifications are in the table

below:

Daisy Chain 4-Wire Modbus Network • Use 22 AWG Belden

shielded / twisted cable (8723).

• Ground shield at one end of the chain only.

• Respect Standard Wiring Practices as explained on page15.

Cradle Communication Module (CCM) • Used with drawout construction.

• CCM requires 50 mA at 24 Vdc control power. Control power source can

be the same as the one powering the BCM. Control power source must

be isolated and ungrounded. See External 24 Vdc Control Power Supply

Characteristics on 11.

• Provides connections for daisy chain communication wires.

• Provides connections for 24 Vdc control power.

• Can be connected to cradle position switches to report circuit breaker

position (connected, test, disconnected) in the cradle.

• Maintains communication parameters (address, baud rate, parity) for the

cradle so when a spare circuit breaker is racked in, the communication

parameters are automatically transferred.

Communicating Shunt Trip and Shunt Close Coils

• Allows opening and closing the circuit breaker through communication

network.

• Connected to BCM.

• Special three-wire shunt trip and close coils are required.

Ethernet Gateway or Circuit Monitor • Modbus TCP / IP Communication

• System Wide Communication

• Web Pages

• Communication from any Browser

• Requires resistor / capacitor terminator at the end of each daisy chain.

Catalog number: 3090MCTAS485

• Belden

cable shield must be connected to ground at only one point. We

recommend that this be done at the master device.

• Maintain color code throughout system.

• Ensure connections are on proper stripped and connection is on wire not

on insulation.

• Do not strip wires more than necessary or they may short together or to

ground and disrupt communication.

• Maintain baud rate and parity throughout the daisy chain.

• Do not use “T” connections except from CCM to BCM, when less than

1 M of cable is needed.

Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 0613IB1201 Section 1—Micrologic Communication System 06/2012

System Problems Most Modbus system problems are related to wiring and addressing.

Never

• Connect 24 Vdc to communication terminals—it will damage the BCM.

• Allow the shield to touch ground at more than one point—it can cause

communication errors due to circulating currents in shield.

• Change cable type—it can cause communication errors.

• Use Modbus address 16 in a mixed-mode daisy chain (mixed mode

means that there are more than one type of communication on the daisy chain). Address 16 can be used by other components in the system leading to communication errors.

• Use SY / MAX address 01 in a mixed-mode daisy chain. Address 01 can be

used by other components in the system leading to communication errors.

• Mix 2-wire and 4-wire devices on the same daisy chain (2-wire Modbus

is not recommended for Micrologic trip unit communication systems)—it can cause additional load on the communication network and slow down or stop communication.

Troubleshooting General

• Ensure all shipping splits and other connections are made.

• Confirm 24 Vdc control power exists at the CCM and E1 / E2 at proper

polarities.

• Confirm circuit breaker is in Test or Connected positions.

• Confirm trip unit is powered (display should be active).

• Check communication parameters and press “address sync” on CCM.

• Check wiring color codes.

CCM LED Indicators

• No LEDs:

24 Vdc control power present.

• One LED solid Green:

24 Vdc control power; no network traffic.

• One LED solid Red:

CCM is defective.

• One LED solid Green with short voids:

seeing good Modbus packets on the wire.

• One LED solid Green with short Red flashes:

indicates the CCM is seeing Modbus packets with errors,

indicates the CCM is connected to a “mixed-mode” daisy chain.

• Pressing “Address Sync” push-button on CCM:

— three (3) flashes of Red followed by three (3) flashes of Green:

information successfully transferred from BCM to CCM,

— three (3) flashes of Red followed by solid Green:

error transferring information from BCM to CCM.

• Racking circuit breaker into Test position:

Wiring Checks with Multi-Meter

• Continuity:

— disconnect master device,

— check continuity between each wire,

— twist each pair together and check for continuity,

— ensure no continuity between wires and ground.

• DC Voltage:

— with system fully connected, but NO communication activity,

— measure between Rx+ / Rx- (green / white) on each slave device:

should measure approximately 4 Vdc,

— measure between Tx+ / Tx- (red / black) on each slave device:

should measure approximately 0.8 Vdc.

Addresses, Baud Rate, and Parity Settings

Micrologic communication system uses four addresses: BCM, CCM, trip unit protection module, and trip unit metering module.

Addresses, baud rate, and parity are set through the HMI for the A, P, or H Micrologic trip units. The HMI address setting actually addresses the BCM from 1 to 47 (47 is the default). The other three addresses are set automatically: CCM = BCM + 50 (97 is default), trip unit protection module = BCM + 100 (147 is the default), and trip unit metering module = BCM + 200 (247 is the default).

Introduction

Module A module contains:

• a table of registers that may be read-accessed only,

• files such as the event log,

• commands for functions such as writing in the registers, turn the circuit

breaker ON or OFF, reset counters, etc.,

• Modbus functions used to remotely access the registers and the manger

files.

NOTE: The commands for the metering and protection modules are

controlled by the breaker communication module.

Command Interface A command interface in the breaker communication module and cradle

communication module is used to control the applications. This interface monitors execution of the command and issues a report.

Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 0613IB1201 Section 2—Communication Architecture 06/2012

Modbus Functions The device and cradle Modbus options operate in slave mode and enable a

Modbus master to access all the registers, files and applications contained in the modules.

Breaker Communication Module: @ Address xx

The breaker communication module may be used to remotely monitor circuit breaker status:

• open (OFF),

• closed (ON),

• tripped (SDE),

• ready to close (PF), and so on.

It is also possible to remotely open or close the circuit breaker if the MX and / or XF communicating coils are installed.

Remote control may be disabled by locally setting the Micrologic control unit to manual (“Manu”) mode. “Auto” mode enables remote control of the circuit breaker.

NOTE: More detailed information on these registers is presented in the

Appendix, Table of Registers, “Breaker Communication Module @ Address xx” on page 57.

Communication Profile In order to optimize the number of Modbus request, a communication profile

has been implemented. The communication profile is located in the breaker communication module @address xx. This communication profile contains information coming from the breaker communication module, the metering module and the protection module. The communication profile is defined in the register range: 12000–12215.

Simplified Open/Close Command In order to simplify the application software to remotely open or close the circuit

breaker, a simplified Open/Close command has been implemented. The simplified Open/Close command is located in the breaker communication module @ address xx. With the simplified Open/Close command, it is not necessary to request the flag, neither to enter in configuration mode, neither to read the control word. It is still necessary to be in Auto mode (see register 670). Furthermore, this simplified Open/Close command is password protected (default value = 0000). In order to change the password, it is mandatory to use the « magic box » and the associated Micrologic utility RSU (please consult us).

The simplified Open/Close command is a share command (command code = 57400).

0613IB1201 Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 06/2012 Section 2—Communication Architecture

NOTE: More detailed information on this command is presented in the

Appendix, List of Command, “Breaker Communication Module Commands @ Address xx” on page 122.

NOTE: Communication profile and simplified Open/Close command are

available only with a Breaker Communication Module firmware version greater or equal to V2.0 (register 577 must be greater or equal to 02000).

Cradle Communication Module: @ Address xx + 50

The cradle communication module indicates the position of the device on the cradle:

• “connected” position,

• “test” position,

• “disconnected” position.

NOTE: More detailed information on these registers is presented in the

Appendix, Table of Registers, “Cradle Communication Module @ Address xx + 50” on page 62.

Metering Module: @ Address xx + 200 The metering module prepares the electrical values used to manage the

low-voltage distribution system.

Every second, the metering module refreshes the “real-time” RMS measurements. Using this data, it then calculates the demand and energy values, and stores the minimum / maximum values recorded since the last reset.

Metering-module operation depends on the Micrologic settings:

• type of neutral (internal, external, none),

• the normal direction for the flow of active power

(this setting determines the sign of the measured power),

• voltage-transformation ratio,

• rated frequency.

The metering module must be set independently of the protection module to determine:

• the calculation mode for the power (type of distribution system),

• the calculation mode for the power factor (IEEE

, IEEE alt., IEC).

Description Details

The minimum values for real-time measurements may be accessed at the registers of the real-time values + 300.

All the minimum values are stored in memory and may be reset to zero, group by group according to the list below, by the command interface:

• RMS current,

• current unbalance,

• RMS voltage,

• voltage unbalance,

Minimum Values for the Real-Time Measurements from 1000 to 1299

• frequency,

•power,

• power factor,

• fundamental,

• total harmonic distortion,

• voltage crest factor,

• current crest factor.

NOTE:

The minimum and maximum values of the real-time measurements are stored in the memory. They may be reset to zero. The maximum values of the demand measurements are time stamped and stored in memory. They may be reset to zero.

The maximum values for the real-time measurements may be accessed at the registers of the real-time values + 600.

All the maximum values are stored in memory and may be reset to zero, group by group according to the list below, by the command interface:

• RMS current,

• current unbalance,

• RMS voltage,

• voltage unbalance,

• frequency,

•power,

• power factor,

• fundamental,

• total harmonic distortion,

• voltage crest factor,

• current crest factor.

The energy counters may be:

• reset to zero,

• preloaded with an initial value,

using the reset applications via the command interface.

The demand values are refreshed every 15 seconds for sliding windows or at the end of the time interval for block windows. When block windows are used, an estimation of the value at the end of the time interval is calculated every 15 seconds.

The time-stamping function becomes useful once the time and date have been set on the Micrologic control unit, either locally or via the communication network.

If power to the Micrologic control unit is cut, the time and date must be set again. With firmware release “logic 2002 AA” and above, the clock is powered by the battery. So, it is no more necessary to set time and date after power comes off on the Micrologic control unit.

If power to the communication option is cut, the time and date must be set again. The maximum drift of the Micrologic clock is approximately 0,36 seconds per day. To avoid any significant drift, the clocks must be periodically synchronized via the communication network.

The configuration registers may be read at all times. The registers may be modified via the command interface in configuration mode.

• RMS / phase of voltage harmonic,

• RMS / phase of current harmonic.

The alarms registers may be read at all times. The registers may be modified via the command interface in configuration mode. These alarms (available with Micrologic H only) can be used to trigger wave form capture.

NOTE: More detailed information on these registers is presented in the

Appendix, Table of Registers, “Metering Module @ Address xx + 200” on page 64.

Protection Module: @ Address xx + 100 The protection module ensures the critical circuit breaker functions. The

Micrologic control unit was designed to make this module completely independent to minimize any issues with the protection functions of the trip units.

It does not use the measurements generated by the metering module, but rather calculates the protection-function inputs and outputs itself. This ensures extremely fast reaction times.

The protection module manages:

• the basic protection: the long-time (LT), short-time (ST), instantaneous

and ground-fault current protection functions,

• the advanced protection: currents I

The protection module controls:

• the automatic load shedding and reconnection functions, depending on

current and power,

• the optional M2C and M6C contacts.

Remote access to the protection module depends on the parameters set locally on the Micrologic control unit and on the position of the protective cover for the settings.

A local operator may disable all remote access to the protection module. It is also possible to limit access to certain users by setting up a password on the Micrologic control unit.

A protection function intended to trip the circuit breaker cannot be modified if the protective cover is closed, with or without the password.

Section 3—Command Interface

Operating Principle Write-access to Micrologic data and control-unit options is monitored to

inhibit accidental operation and operation by unauthorized persons.

Commands sent to Micrologic control units are carried out using a command interface.

The command interface manages transmission and execution of the various commands using the registers numbered from 7700 to 7729 that may be accessed by the Modbus read and write functions.

The breaker communication module supports the command interface for the commands intended for the circuit breaker, measurement, and protection modules.

The cradle communication module supports its own command interface.

—

The command interface offers two command modes:

• Shared Mode:

This mode may be used to send up to 20 commands in series. It returns exclusively the indications on command transmission via the Modbus protocol. This mode does not return the result of command execution.

• Protected Mode:

This mode may be used to monitor execution of a command and to manage access by a number of supervisors to a single circuit breaker. This is the case for the Modbus multi-master architectures on Ethernet TCP / IP.

When a command is written, the command interface updates its registers

with information on command execution. It is necessary to wait until the command is terminated before sending the next command.

(Recommended time-out is 500 ms.)

Furthermore, when the command is terminated, it is necessary to respect a delay before sending the next command.

(Recommended delay is 20 ms.)

Access control is achieved by a flag reservation and freeing mechanism. In protected mode, a command may be issued only after receiving a flag.

NOTE: Certain commands may be accessed only in protected mode. See

“List of Commands” on page 121 to determine the possible commandmanagement modes.

2. Write Command

Write the command number to register 7700 to initiate execution.

It is possible to optimize data flow on the communication system by using function 16 in the Modbus protocol. In this case, the data may be written to registers 7700 to 7709 in a single step. The circuit breaker communication option will automatically put steps 1 and 2 in the correct order.

Register 7715 must be read-accessed to ensure it is 0, if it is not 0 then another user is in configuration mode and you cannot proceed to the next step, see page 128.

The active flag indicates to a supervisor the number of the flag with current access rights to the command interface in protected mode. Only the supervisor that was attributed the given number during a flag query has the right to use the command interface in protected mode. The active flag returns to 0 if no command is sent for two minutes or if the user returns the flag (see the command table for information on return).

he number of the command currently being executed remains set to 0 as long as no command is sent to 7720. As soon as a command is sent, register 7717 indicates the number of the command. It returns to 0 when command execution is terminated.

When command execution is terminated, register 7718 receives the number of the command and register 7719 indicates the result code. The contents of registers 7718 and 7719 are not modified until the next command has been completely executed

See the “List of Commands” on page 121 that may be accessed in protected mode and the corresponding parameters in the section with the list of commands for Micrologic control units.

Command interface registers 7730–7829 may be read accessed. They are used as a buffer for the returned data.

Proceed as follows to send a command in protected mode.

1. Request the Flag

Read register 7715 to ensure it is 0, if it is not 0 then another user is in

configuration mode and you cannot proceed to the next step, see

page 128. It is possible, however, that you already took the flag for

another command and did not return it. For example: if you wished to

sequence sending of a series of commands. It is possible to check if you

have the rights by reading the active flag at register 7716. In this case,

even if you did not read 0 at 7715 when you made the request, it is

possible to send the commands.

2. Fill in Parameters

Fill in the command parameters (P1 to P9) in registers 7721 to 7729.

3. Write Command

Write the command number to register 7720 to initiate execution.

4. Wait for Command Execution

Wait until the command is fully terminated, by reading registers 7717

and 7718 (recommended time-out = 500 ms).

5. Check Result Code

Check the result code for the command by reading register 7719.

6. Send New Command

Send new commands in protected mode by starting with step 2 or go on

to step 7 (recommended delay between command fully terminated and

new command = 20 ms).

7. Release the Flag

Return the flag to free the protected mode. See the command table for

information on returning the flag.

Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 0613IB1201 Section 3—Command Interface 06/2012

Optimize Sending of Commands It is possible to optimize data flow on the communication system by using

function 16 in the Modbus protocol. In this case, the data may be written to registers 7720 to 7729 in a single step. The command interface will automatically put steps 2 and 3 in the correct order.

NOTE: Do not use function 23 to optimize steps 1, 2 and 3, because this

function does not check access rights to protected mode before sending the command. This may cause problems for another supervisor who currently has the access rights.

Most of the commands that may be used to remotely control the circuit breaker implement two steps, namely the request for the flag (step 1) and return of the flag (step 7).

This mechanism makes it possible for a number of supervisors to issue commands, on the condition that the two steps be implemented.

Using this procedure, you take and return the flag for each of the commands to be issued. In this case, the possible degree of parallelism between the various supervisors is increased, but at the cost of more traffic on the communication system.

If you have a number of commands to send, optimize the mechanism by sending all the commands between the two steps; for example, request the flag, send all the commands in one shot and then return the flag. In this case, you occupy the command interface for a longer time, but traffic on the communication system is optimized.

Remote Configuration

NOTE: Detailed information on the registers is

presented in the Appendix containing the “Table of Registers” on page 55.

A number of simple concepts must be clear in order to remotely configure the circuit breaker successfully.

• Configuration is carried out via the registers:

The configuration for all the modules (circuit breaker, cradle, measurements, and protection functions) may be read-accessed in the table of registers.

The only way to remotely modify a configuration is to modify the contents of the configuration registers.

• The table of registers may be write-accessed in configuration mode only:

To modify the configuration registers, it is necessary to remove the register write-protect function by running the command required to enter configuration mode, via the command interface. Once in configuration mode, it is possible to write access the configuration registers and you may modify one or more registers using the standard Modbus write functions.

Specific conditions must be met to enter the configuration mode.

Remote access is not possible if local configuration is underway and visa-versa.

When a user is in the process of locally modifying the configuration of Micrologic or of its options, it is not possible to start a remote-configuration sequence.

Micrologic considers that a local user is in the process of modifying the configuration when a parameter field is highlighted or as soon as the Micrologic plastic cover is opened.

Access to configuration mode is subject to different restrictions depending on the module.

Access to configuration mode for the protection module requires the remote-access code that was programmed on the front panel of the Micrologic control unit.

This code may be obtained only via the setting screen on the Micrologic control unit itself. It is only possible to access the configuration mode for the protection module if the Micrologic control unit has been set to authorize remote access. This setting must be made manually via the front panel of the Micrologic control unit. It is possible to consult the protection module register 9800 to check the status of this parameter.

Access to configuration mode for the breaker communication, cradle communication and metering modules requires a check word that must first be read in the table of registers. This two-step operation is intended to avoid inadvertent access to the configuration mode.

The access commands for configuration mode implement the protected mode and systematically inform on the command result.

New configurations are always checked before being accepted.

When writing in the configuration registers, the Modbus write functions are accepted, even if the written value exceeds the limits presented in the tables of registers that should be consulted first.

To assist in configuring the protection functions, Micrologic provides access to a set of registers that list the minimum and maximum permissible values for the various protection settings.

Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 0613IB1201 Section 3—Command Interface 06/2012

All the configuration data entered are checked before they enter into effect. This check is run when you exit configuration mode, using the commands Out_pCfg, Out_mCfg or Out_CommCfg.

If one of the configuration settings is incorrect, all the new configuration data are rejected. The system indicates why the data are rejected via the result returned for the command used to exit the configuration mode. The protection module indicates the first ten faulty configuration registers. See the information on command Out_pCfg for further details.

The new configuration data take effect only on exiting configuration mode.

The new configuration data take effect only on exiting configuration mode so that the data can be checked; for example, it is when the Out_pCfg, Out_mCfg or Out_CommCfg command has been successfully run that the new configuration settings become active.

Example of a Remote Parameter-Setting Sequence

Below are the steps that must be followed to modify the long-time (LT) current setting.

1. Check that remote access is authorized by reading register 9800 at address @+100 [protection module].

2. Make sure you have the remote-access code, noted on the “Local / Remote” screen in the “COM setup” menu of Micrologic.

3. Enter configuration mode for the protection module, using the In_pCfg command. See the Appendix, “Examples of Commands” on page 127.

4. Enter the new setting in registers 8753 to 8803, at the address @+100 [protection module]. Make sure these new settings are below the value set by the rotary switch.

5. Exit configuration mode for the protection module, using the Out_pCfg command, and check first for an error code returned by the command interface, then the parameters returned by Out_pCfg in registers 7730 to 7739 of the circuit breaker command interface.

6. Read the contents of the registers 8756 and 8757. The settings should be those entered, if step 5 did not return an error.

Section 4—Access to Files

Introduction Micrologic stores events and wave form in different files. These files may be

read with the command interface: ReadFileX_RecY. The requested recording may be read starting in registers 7730. See the Appendix, “Examples of Commands” on page 127.

A file is made up of records. All records in a file have the same structure and size.

Each file is linked to a descriptor. The descriptor is made up of a read zone for file configuration (Header) and for file characteristics (Status). Descriptors are updated each time new data is added to the file.

The file configuration (Header) gives information about size of file and records. The file characteristics (Status) gives information about record numbers. The file characteristics (Status) makes available to the supervisor two sequence registers that indicate the first and last events recorded in the file. They enable the supervisor to determine whether certain events were deleted before they could be read. The sequence number for the last event increments from 1 to 8000 each time a new event is recorded. When the file is full (maximum of 100), the new events overwrite the oldest events. The sequence number for the last event continues to increment normally. When the oldest event is overwritten, the sequence number for the first event also increments.

When the sequence number reaches 8000, the next sequence number will be one.

Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 0613IB1201 Section 5—Modbus Functions 06/2012

Section 5—Modbus Functions

Introduction Modbus is an application layer messaging protocol, positioned at level 7 of

the OSI model, that provides client/server communication between devices connected on different types of buses or networks.

The Internet community can access Modbus at a reserved system port 502 on the TCP/IP stack.

Modbus is a request/reply protocol with services specified by function codes.

Modbus / JBus Protocol In the Modbus protocol, register numbering begins with 1, whereas in the

JBus protocol, numbering of the equivalent registers begins with 0. However, a JBus master can dialogue with a Modbus slave by addressing a register number –1 to access the correct register on the Modbus slave.

Example of a request to read a register.

In order to read the rms current on phase A (register 1016), you will have to address the register number 1016 – 1 = 1015 1015 = 0x03F7 (hexa).

Request Response

Function — 03 Function — 03

Starting Address Hi 03 Byte count — 02

Starting Address Lo F7 Register value Hi 02

N° of registers Hi 00 Register value Lo 2B

N° of registers Lo 01 — — —

The contents of register 1016 (rms current on phase A) are shown as the two byte values of 02 2B (hexa), or 555 (decimal). Therefore, rms current on phase A is 555 Amps.

Modbus Exception Responses When a client device (master) sends a request to a server device (slave) it

expects a normal response. One of four possible events can occur from the master’s query:

• If the server device receives the request without a communication error,

and can handle the query normally, it returns a normal response.

• If the server device does not receive the request due to a

communication error, no response is returned. The client program will eventually process a time out condition for the request.

• If the server device receives the request, but detects a communication

error (parity, LRC, CRC,…), no response is returned. The client program will eventually process a time out condition for the request.

• If the server device receives the request without a communication error,

but cannot handle it (for example, if the request is to read a non existing register), the server will return an exception response informing the client of the nature of the error.

0613IB1201 Modbus™ Communications System for Micrologic™ A, P, and H Trip Units 06/2012 Section 5—Modbus Functions

The exception response message has two fields that differentiate it from a normal response:

Function code: Function code of the original request + 0x80 (hexa)

Exception code: See the following list

01 ILLEGAL FUNCTION

02 ILLEGAL DATA ADDRESS

03 ILLEGAL DATA VALUE

Advanced Modbus Functions Read n non-contiguous registers (function 100, sub-function 4).

The n non-contiguous registers must be specified one after the other by their register in the data table. The maximum for n is 100 (When using Micrologic A, it is recommended to have n less than or equal to 21).

To optimize access to Micrologic and its COM options, it may be very useful to read n non-contiguous registers in a data table.

Use of function 100, sub-function 4 avoids:

• reading a large block of contiguous data when only a few elements of

data are required,

• multiplying read functions for n registers (functions 3 and 4) or for one

word (function 1) simply to read a few elements of non-contiguous data.

The table below provides an example of reading the data in registers 101 and 103 of the slave with the Modbus address 47.

ASCII

If the most-significant bit is set, the date and time may be incorrect. There are two possibilities:

• no synchronization with the supervisor,

• loss of power. If power has been lost, the self-test bitmap “D/T loss” is enabled until the date and time are enabled (via the control unit or the communication module).

UINT corresponds to a 16-bit unsigned integer with an interval of values from 0x 0000…0 x FFFF (0…65535).

INT corresponds to a 16-bit signed integer with an interval of values from 0x 8000…0 x 7FFF (-32768…+32767).

Mod10000 corresponds to n registers in the INT format.

Each register contains an integer from 0 to 9999. A value V representing n registers is calculated as indicated below:

V = sum(R[n] + R[n + 1] x 10000 +..+ R[n + m] x 10000 (m-1)), where Rn is the number of register n.

Example: Register 2000 = 123; Register 2001 = 4567; Register 2002 = 89; Register 2003=0 Energy = 123 + 4567 x 10 000 + 89 x (10 000)² + 0 = 89 4567 0123 kWh

SFIXPT corresponds to a signed INT integer with a fixed point. The position of the point is indicated by the scale factor. The interval of values is:

-32767… +32767 with a scale factor “x 1”.

Other example:

-32.767 … +32.767 with a scale factor “x 1000”.

Date corresponds to a normal date made up of three UINT, as follows:

• first UINT: month expressed using the eight most-significant bits (January = 0x41) day expressed using the eight least-significant bits,

• second UINT: year expressed using the eight most-significant bits (modulo 100) (00 to 49 = years 2000 to 2049, from 50 to 99 = years 1950 to 1999) hours expressed using the eight least-significant bits,

• third UINT: minutes expressed using the eight most-significant bits seconds expressed using the eight least-significant bits.

XDATE corresponds to an extended date made up of four UINT, as follows:

• first UINT: month expressed using the eight most-significant bits (January = 0x41) day expressed using the eight least-significant bits,
