Specific product profiles are located in the other Part sections . http://www .eaton .com, then search on 17384 .

“Modicon Modbus Protocol” http://www .modicon .com/techpubs/toc7 .html

Overview

I

The contents of Modbus registers are INCOM product objects (e .g .,

A

—phase A current) . The mMINT ensures that unique objects reside in identical registers independent of INCOM product . Consequently, for all INCOM products there is a single register map of objects .

See Table 8 or Table 9 .

INCOM objects occupy two registers except for certain energy—real and reactive—objects . These energy objects occupy four registers .

The mMINT can support a maximum of 122 registers within a single

Modbus transaction .

The mMINT is transparent to the Modbus master and responds to every address of INCOM products attached to it . In its default configured state, INCOM product addresses are Modbus network addresses . The mMINT can be configured to route the Modbus address to a different INCOM product address or an INCOM sub-network product address . See Section 6 .

An upgrade has been incorporated to allow the mMINT to communicate with Modbus masters that can only access to register 9999 . Registers previously assigned above 9999 have been assigned dual access, both at the original register (to provide compatibility) and at a new register assignment below 9999 .

The format is given as low/high register numbers followed by

(low

16

/high

(XXXX+1

16

16

Modbus register addresses), for example: 4xxxx/4yyyyy

/YYYY+1

16

) . See Table 14 .


Effective July 2009

Only the RTU communications mode is recognized by the mMINT .

Function codes

The mMINT responds to a limited number of Modbus function codes . These are function codes 03, 04, 08, and 16 (10

16

) .

Block of registers

A block of registers (from the register column of Table 8 or Table 9) can be established for each INCOM product attached to a mMINT .

Function code 16 (10

16

) is used to load the object assignments for the block of registers . The block assignments are stored beginning at register 41001/420481 (03E8 address is assigned within the block of registers . For example, although object I

(1203

16

A

16

/5000

16

) .Only the first object register

occupies registers 404611 (1202

16

), only register address (1202

16

) and 404612

) is loaded into the block of assignment registers . Verification of this block of assignment registers can be read from the mMINT by a read function code 03 or 04 from these 41001/420481 (03E8

16

/5000

16

) registers .

Data pertaining to the objects configured in the block of assignment registers is mapped into registers starting at 41201/420737

(04B0

16

/5100

16

) and continuing in successive order for each object assigned . The number of objects and their placement order in this data block of registers is dependent on the configuration of the block of assignment registers . The total number of data block of registers is limited to 100 .

N ote:

An object can occupy one, two, or four registers .

The data can be obtained from the data block of registers by a read function code 03 or 04 . The address of the starting object must be aligned with a starting address of an object within the data block of registers . The number of registers to obtain must align with an ending address of an object within the data block of registers .

Register access configurations

Non-volatile register 42001/425345 (07D0

16

/6300

16

) is used to configure the mMINT to respond to a group of data objects, of which some objects are invalid within that group . When non-zero

(factory default value), any attempt to access a group of data objects that contain an invalid object will result in an illegal data object exception code 02 . See Section 6 .

When register 42001/425345 (07D0

16

/6300

16

) is set to zero, however, the mMINT will respond to a group of objects with data contained in the valid objects of the group along with an illegal value, if available else 0000

16

, data contained in the invalid objects .


16

/6301

16

) is used to configure 32-bit IEEE floating point word order . When non-zero

(factory default), the floating point low order word is first in the

Modbus register space .

INCOM routing address configurations

Non-volatile registers 42101 (0834

16

) through 42592 (0A1F

16

) are used to configure the 246 Modbus-to-INCOM Routing Address registers . Two consecutive INCOM routing registers correspond to each Modbus address . The first register provides routing to an

INCOM main network address while the second (first+1) register provides routing to an INCOM sub-network address . Registers

42101 and 42102 correspond to Modbus address 1, registers 42103 and 42104 correspond to Modbus address 2, etc .

Valid INCOM addresses range from 0001

INCOM addresses are 0000

16

or Yxxx

16

16

through 0FFF

16

. Invalid

, where Y is non-zero . Any invalid (default) setting in the INCOM main network address register will cause the mMINT to access the INCOM product with the

Modbus network address . A valid INCOM main network address register with an invalid INCOM sub-network address register will route the Modbus network address to the INCOM product at the configured main network address . Both a valid INCOM main network address register and INCOM sub-network address register will route the Modbus network address to an INCOM product at the configured sub-network address accessed through a sub-network master addressed at the INCOM main network address .

All INCOM Routing Address Configuration registers can be reset to their default state using the Diagnostics function code 08, subfunction 30 (1E

16

) . See Section 6 and Table 6 .

Command/data pass-through

A feature of the mMINT is its capability to pass INCOM commands/ data directly through to any of 32 attached INCOM products . Thus, with access to IL 17384, Parts A through F, every INCOM product object and capability is available to the Modbus master .

When passing a command or data through to an INCOM product, the mMINT acts as a dumb slave . Without modification, it passes the command or data through to the INCOM product .

In the event the product responds, the mMINT saves the response until the Modbus master queries for that response . The response data remains in the mMINT until another pass-through command is issued to an attached product or a mMINT power cycle occurs . The mMINT makes no modification to or interpretation of the product response data .

The Modbus master writes the INCOM product command/data using function code 16 (10

(0A28

16

/6000

16

) .

16

) beginning at register 42601/424577

The data format for passing information through the mMINT to an

INCOM product is given in Figure 8 .

The Modbus master reads the INCOM product response to a passthrough query using either function code 03 or 04 beginning at register 42701/424833 (0A8C

16

/6100

16

) .

The number of points (registers) of the read query is 2*nn—where nn is the number of INCOM messages in the response .

The format of the data acquired by the mMINT from the passthrough INCOM product query’s response is given in Figure 7 .

N ote:

Each INCOM response message contains a status byte that indicates its validity .

Control of INCOM product

Since a control error could result in unwanted actions initiated by an INCOM device, the mMINT requires a specific protocol by the

Modbus master in order to perform control related functions within the INCOM product .

A set of registers is reserved for the control protocol . They begin at register 42901/425089 (0B54

42903/425091 (0B56

16

/6202

16

16

/6200

16

) and extend through

) . These three registers are written with a ‘slave action number’ and its 1’s complement using function code 16 (10

16

) . The current ‘slave action numbers’, their support being product dependent, are listed in Table 13 . The format of the data is shown in Figure 8 . These three registers, and only these three registers, must be written in one Modbus transaction .

If the ‘slave action number’ and its 1’s complement are valid, the mMINT issues the ‘slave action’ control command onto the INCOM network . If the slave action request is successfully acknowledged by the INCOM product, the mMINT returns a normal function code

16 (10

16

) response to the Modbus master . The Modbus master may further determine if the INCOM product completed the slave action function successfully by interrogating the product, for example, by reading its status .

If the INCOM product does not acknowledge the slave action request, the mMINT returns an exception code 04 . If the ‘slave action number’ and its 1’s complement are invalid, the mMINT responds to the Modbus master with a data value illegal exception code 03 . See Section 6 .

Energy format

Energy objects in the mMINT are supported in 2-register fixed point object format and a 4-register power/mantissa format . These objects do not support IEEE floating point format .

The 2-register format is presented in units of Kwatthours and is valid for INCOM products reporting energy in watthours or Kwatthours only . Products reporting in units greater than Kwatthours (e .g .,

Mwatthours) could not guarantee consistent Kwatthour resolution up to and through their rollover values .

All products reporting energy (independent of energy units) support the energy objects occupying four registers—register 3 through register 0 . Register 3 is the high order register and register 0 is the low order register .

Register 3 high byte contains a value corresponding to Engineering

Units (power of 10 signed exponent) . Register 3 low byte contains a

Mantissa Multiplier value (power of 2 signed exponent) .

Register 2 through register 0 contains a 48-bit energy mantissa in units of watthours . Net and total energy objects are signed values .

All other energy objects are unsigned values .

The data format of these four registers is given in Figure 9 .

Supported diagnostic sub-functions

It is possible to obtain diagnostics from the mMINT or an attached

INCOM product using function code 08 . See Table 6 . A single register is used for each UART counter within the mMINT . Each

INCOM device and the mMINT contain a unique slave counter .

To use mMINT address 247 or 248 in the diagnostic query, SW2-1 must be properly set . See Section 5 and Table 5 .

Exception codes

Under certain circumstances, the mMINT will return an exception code .

If the function in the query is not supported by the mMINT, exception code 01 is returned in the response .

If the data (object) register is illegal, exception code 02 is returned in the response .

If the data value in the query is illegal, exception code 03 is returned .

If the slave INCOM product fails (usually a timeout), exception code

04 is returned .

In certain circumstances, an exception code 05 (ACK) is returned .

If the mMINT cannot perform the requested function, exception code 07 (NAK) is returned .

If only a partial register is used in the query, exception code 84 is returned .

Section 7: troubleshooting

The most common issues experienced with the installation of an mMINT module are addressed below .

If you have any questions or need further information or instructions, please contact your local Eaton representative or the Customer

Support Center at 877-ETN-CARE (877-386-2273) .

Table 7. Troubleshooting Guide

Symptom

Status leD not flashing

Modbus Tx leD is flashing, but the module does not respond to master command requests

INCOM Tx leD is flashing, but the module does not respond to master command requests

Removing an INCOM product and assigning its INCOM (Modbus) address to another (different) INCOM product, and exception codes are received from the INCOM product

Possible Solution(s)

Verify proper input power to module connector

Verify communication cable is connected correctly from the master to the module (A, B, +, –)

Verify the data transfer rate is correctly set using baud rate switch (SW2)

Verify communication cable is connected correctly from the slave to the module

Verify the product is set up for 9600 baud

Verify that the termination switch (SW1) is set to

ON at the last module

Disconnect the reassigned product from the

INCOM network

Verify that the Modbus Master has sent at least two requests to the address of the product that was just disconnected

Connect the reassigned INCOM product
