All the Compact devices can be fitted with the
communication function thanks to the COM option.
Compact uses the Modbus communications protocol
for full compatibility with the supervision management
systems. An external gateway is available for
communication on other networks:
Eco COM is limited to the transmission of metering
data.
It is not used to communicate status and controls.
For fixed devices, the COM option is made up of:
a Modbus BCM ULP “device” communication module, installed behind the
b
Micrologic control unit and supplied with its set of sensors (OF, SDE ,PF and CH
micro switches) its kit for connection to XF and MX1 communicating voltage releases
and its COM terminal block (inputs E1 to E6).
For drawout devices, the COM option is made up of:
a Modbus BCM ULP “device” communication module, installed behind the
b
Micrologic control unit and supplied with its set of sensors (OF, SDE, PF and CH
micro switches) its kit for connection to XF and MX1 communicating voltage releases
and its COM terminal block (inputs E1 to E6).
a “chassis” communication module supplied separately with its set of sensors (CE,
b
CD and CT contacts) Modbus CCM.
Modbus BCM ULP “Device” communication module
This module is independent of the control unit. It receives and transmits information
on the communication network. An infra-red link transmits data between the control
unit and the communication module.
Consumption: 30 mA, 24 V.
Modbus CCM “chassis” communication module
This module is independent of the control unit. With Modbus “chassis”
communication module, this module makes it possible to address the chassis and to
maintain the address when the circuit breaker is in the disconnected position.
Consumption: 30 mA, 24 V.
