The Modbus controller EM12D-TMB is the centre of the
ControlPlex
®
system. It collects all information of
the REX12D electronic circuit protectors and forwards it to the superordinate Modbus server and thus to the
superordinate control unit.
The Modbus interface to the superimposed control unit is realised with a 3-wire cable. It allows connection
of the
ControlPlex
®
system to the Modbus server, thus enabling display and analysis of the individual
measuring values as well as diagnosis and control of the individual electronic circuit protectors. The user has
unrestricted access to the safety-relevant functions in the event of a system disruption. Any occurring failures
will be detected quickly and can be remedied without delay. The
ControlPlex
®
system effectively reduces
system downtimes and significantly increases the productivity.
