1.0 GENERAL
DESCRIPTION
The mMINT (Modbus Master INCOM Network Translator)
Module, as seen in Figure 1, is a Cutler-Hammer accessory
product that will provide communication between a Modbus
RTU network and an INCOM (INdustrial COMmunications)
network (see
Figure 2
). This module is transparent to the
Modbus network. It communicates to a master on the Modbus
network using the Modbus RTU (Remote Terminal Unit)
protocol. It communicates to slave devices on the INCOM
network using the IMPACC (Integrated Monitoring, Protection,
And Control Communication) protocol. The catalog number of
this product is
MMINT
.
2.0 FEATURES
The mMINT module is a slave device on the Modbus network
and as such requires a master that will exchange register
objects with the mMINT module.
•
Handles generic pass though commands (Modbus/IN-
COM/Modbus).
•
Capable of passing Modbus register objects from Cutler-
Hammer’s existing products and newer PnP (Plug-‘n-Play)
products to a Modbus RTU master.
•
Data in IEEE Floating Point format and fixed point.
•
Modbus RTU communications data transfer rates of 1200,
9600, or 19200 baud with 1 start bit, 8 data bits, no parity
and either one or two stop bits.
•
Up to 32 products connected to INCOM network port (246
unique addresses maximum).
•
Flashing Status LED to indicate an active module.
•
LED indicators for INCOM transmit and receive
communications exchanges.
•
LED indicators for Modbus RS485 transmit and receive
communications exchanges.
•
Input power for the module from either 120 Vac or 48 to
125 Vdc.
•
DIN rail mount package.
•
0ºC to 60ºC ambient operation.

3.1 Module
Mounting
When mounting the mMINT verify that an
11mm H x 28mm W
DIN Rail
is used and that it is within an enclosed space.
3.2 Simplified Wiring Rules
3.2.1 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
IMPACC wiring specification T.D. 17513.
