Modbus interface module
Functions
This module, required for connection to the network,
contains the Modbus address (1 to 99) declared by the
user via the two dials in front. It automatically adapts
(baud rate, parity) to the Modbus network in which it is
installed.
It is equipped with a lock-out switch to enable or disable
operations involving writing to Micrologic, i.e. reset,
FRXQWHU UHVHW VHWWLQJ PRGL¿FDWLRQV GHYLFH RSHQLQJ
and closing commands, etc.
There is a built-in test function to check the connections
of the Modbus interface module with the Micrologic and
FDM121 display unit.
Mounting
The module is mounted on a DIN rail. A number of
modules may be clipped one next to the other.
For this, a stacking accessory is available for fast clip-
connection of both the Modbus link and the 24 V DC
supply.
The Modbus interface module supplies 24 V DC to the
corresponding Micrologic, FDM121 display and BSCM
module. Module consumption is 60 mA / 24 V DC.
BSCM module
Functions
The optional BSCM Breaker Status & Control Module
is used to acquire device status indications and control
the communicating remote-control function.
It includes a memory used to manage the maintenance
indicators.
Status indications
Indication of device status:
O/F, SD and SDE.
Maintenance indicators
The BSCM module manages the following indicators:
mechanical operation counter
b
electrical operation counter
b
history of status indications.
b
It is possible to assign an alarm to the operation
counters.
Controls
The module can be used to carry out communicating
remote control operations: (open, close and reset) in
different modes (manual, auto).
Mounting
The BSCM module can be installed on all Compact
NSX circuit breakers and switch-disconnectors. It
simply clips into the auxiliary contact slots. It occupies
the slots of one O/F contact and one SDE contact. The
BSCM is supplied with 24 V DC power automatically
via the NSX cord when the communication system is
installed.
