SEM Cxx

SEM Cxx

is a central module of the SEM system. It is equipped with tools for communication with

SCADA systems.

Fig. 3.5. Module SEM C12

The module communicates with the parent system by means of DNP 3.0, IEC 60870-5-104 or MODBUS
communication protocols and using GSM, Ethernet and RS 232/422/485 links. Thanks to the interaction
with the ELF application tool, the controller operation can be fully programmed, for example:



Inspection of the temperature increments in distribution panels.



Control and monitoring of the status of switches in MV panels.



Current and voltage protections.



Automation – monitoring and enforcing of the state of binary inputs.

The module acts as a data hub with all elements of the SEM system and is connected with these elements
via the bus. This enables a remote configuration of modules and software exchange as well as the registration
of events in the log.
