System description
2.3 COM190 communication module
• Readout of status and maintenance information
• Security functions
The COM190 is equipped with Ethernet interfaces for connecting to the PC or network.
Communication protocols and systems
The COM190 communication module supports the following communication protocols:
• PROFINET IO
• Modbus TCP
It is possible to use only one protocol or both protocols simultaneously and independently of
each other. Since no configuration is required, the 3WA circuit breaker can be used in
different systems simultaneously. An air circuit breaker can thus be used, for example,
simultaneously in energy management and automation.
Two COM190 modules performing different roles (role A and role B) can also be operated
simultaneously on the same circuit breaker. This allows the circuit breaker to provide new
redundancy solutions, as it can be used in parallel in two independent communication
systems.
Security
COM190 is a modern communication module and offers security functions to prevent
unauthorized access to the circuit breaker or unauthorized changes to data via
communication.
