Simplified wiring rules

INCOM network

The following simplified rules apply to a given system consisting of

a single daisy-chained main cable link between master and slave

devices (see Figure 2). For more complex considerations, including

star configurations, please refer to the wiring specification T.D. 17513.

• Recommended INCOM cable styles are Belden 9463 or

C-H style 2A957805G01

• The maximum system capacity is 10,000 feet of communications

cable and 32 slave devices on the INCOM network under

the mMINT

• Non-terminated taps, up to 200 feet in length, off the main link

are permitted, but add to the total cable length

• Make sure that there is twisted-pair wire that is recommended for

PowerNet network use. Use shielded twisted-pair wire to connect

each slave to the INCOM network, daisy-chain style. The polarity

of the twisted pair is not important.

Modbus RS-485 network

The following simplified rules apply to a given system consisting of

a cable link between master and slave devices (see Figure 2). For

more complex configurations, please refer to standard Modbus RTU

wiring specification rules for the RS-485 network.

• The recommended Modbus cable has twisted-pair wires

(24 AWG stranded 7x32 conductors with PVC insulation)

having an aluminum/mylar foil shield with drain wire

• The maximum system capacity is 4000 feet of communications

cable and 247 devices on the Modbus RTU network

• Make sure that there is twisted-pair wire that is recommended

for Modbus RTU network use. Use shielded twisted-pair wire

to connect each slave to the Modbus RTU network, daisy-chain

style. The polarity of the twisted pair is critically important.

Section 4: mMINT module connections

Section 6: Network communication protocols

The lower INCOM communication network for the mMINT is

based on a master-slave protocol. The mMINT is a master on the

INCOM network.

In order to satisfy the mMINT communications needs, please see

Reference Materials:

IL17384—Part A: INCOM Communications Standard, Eaton.

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

The contents of Modbus registers are INCOM product objects

(e.g., IA—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

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

(low16/high16 Modbus register addresses), for example:

4xxxx/4yyyyy (XXXX+116/YYYY+116). See Table 14.

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 (1016).

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 (1016) is used to load the object assignments for

the block of registers. The block assignments are stored beginning at

address is assigned within the block of registers. For example,

although object IAoccupies registers 404611 (120216) and 404612

(120316), only register address (120216) 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 (03E816/500016) registers.

Data pertaining to the objects configured in the block of assignment

registers is mapped into registers starting at 41201/420737

(04B016/510016) 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.

ote:N 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.

Non-volatile register 42001/425345 (07D016/630016) 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 (07D016/630016) 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 000016, data contained in the invalid objects.

Non-volatile register 42002/425346 (07D116/630116) 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.

When register 42002/425346 (07D116/630116) is set to zero, however,

the floating point high order word is first in the Modbus register

space.

Non-volatile register 42002/425347 (07D116/630216) is used to

configure 32-bit fixed point and 64-bit energy word order. When

non-zero (factory default), the fixed point and energy low order

word is first in the Modbus register space.

When register 42003/425347 (07D216/630216) is set to zero, however,

the fixed point and energy high order word is first in the Modbus

Registers not containing a 32-bit or 64-bit format, such as Status and

Product ID objects, pass through registers, INCOM control registers,

and INCOM routing address configuration registers, are not effected

by the word order configuration registers.

Configuring any or all registers 42001/425345 through 42003/425347

(07D016/630016 through 07D216/630216) is accomplished using a write

function code 16 (1016) to mMINT diagnostic address 247 or 248.

ote:N mMINT SW2-1 must be properly set. See Section 5 and Table 5.

INCOM routing address configurations

Non-volatile registers 42101 (083416) through 42592 (0A1F16) 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 000116 through 0FFF16. Invalid

INCOM addresses are 000016 or Yxxx16, 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

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,

sub-function 30 (1E16). 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 (1016) beginning at register 42601/424577

(0A2816/600016).

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

pass-through query using either function code 03 or 04 beginning

at register 42701/424833 (0A8C16/610016).

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 pass-

through INCOM product query’s response is given in Figure 7.

ote:N 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 (0B5416/620016) and extend through

42903/425091 (0B5616/620216). These three registers are written

with a ‘slave action number’ and its 1’s complement using function

code 16 (1016). 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 (1016) 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

low order register.

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

Mantissa Multiplier value (power of 2 signed exponent).

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.

Energy = 2Mantissa Multiplier x (48-bit energy value) x 10Engineering Units.

Appendix A

otes:N

1. Modbus is a registered trademark of Schneider Electric.

2. mMINT modules use DIN rail mounting.

3. Control voltage is 120 Vac +/–20% or 24–125 Vdc.

4. Connectors are plug-in types from Phoenix contact.

5. Terminal Types (supplied with module) are 3-point, 4-point, and

5-point Phoenix contact.

• MVSTBR2,5/3-STF-5,08 (Order No. 1835106)

• MVSTBR2,5/4-STF-5,08 (Order No. 1835119)

• MVSTBR2,5/5-STF-5,08 (Order No. 1835122)

6. INCOM communications cable is Eaton C-H style 2A957805G01

or Belden style 9463.

7. Set up switch SW1 to insert 100 ohm terminating resistor on

last module in the INCOM network.

8. Set up switch SW2 to select data transfer rate on the

Modbus network.

9. Set up switch SW3 to insert 121 ohm terminating resistor on

last module in the Modbus network.

10. Power wiring is any approved 300 V, 10 A, 30–12 AWG

(stranded or solid).

11. The register map for INCOM products is shown in register

number order in Table 8 and functional order in Table 9.

Numeric entries indicated with an asterisk (*) have specific

definitions dependent upon the particular INCOM product.

These tables include only a partial list of applicable INCOM

products; however, it contains a complete list of the INCOM

objects directly supported by the mMINT. Due to the mMINT

pass-through feature, all INCOM product objects are accessible

by a Modbus master.

12. The primary and secondary codes are mapped to the high

and low bytes, respectively, of registers 404609 (120016)

and 406145 (180016). The primary status codes are shown in

Table 10. The secondary status codes are shown in Table 11.

The cause-of-status codes are mapped to registers 404610

(120116) and 406146 (180116). The cause-of-status codes are

shown in Table 12.

13. Catalog number is MMINT.
