COM800 / COM100 breaker data server
The COM800/COM100 breaker data servers can be used to integrate communication-
capable 3VA UL molded case circuit breakers, with 5-series and 8-series trip units, into
various communication networks.
● The COM800 breaker data server supports a maximum of eight 3VA UL molded case
circuit breakers
● The COM100 breaker data server supports one 3VA UL molded case circuit breaker
3VA molded case circuit breakers can be connected to higher-level communication networks
by the following methods:
● Direct Ethernet connection to Modbus TCP
● 7KM PAC PROFIBUS DP expansion module to PROFIBUS DPV1 / V2
● 7KM PAC Switched Ethernet PROFINET expansion module to PROFINET IO and
PROFIenergy, as well as Modbus TCP
● 7KM PAC RS 485 expansion module for Modbus RTU
The 3VA UL molded case circuit breakers are typically integrated in the power monitoring
software powermanager or the TIA (Totally Integrated Automation) automation concept via a
communication network.
The 3VA UL molded case circuit breakers can also be connected to the commissioning and
service software powerconfig.
The 3VA UL molded case circuit breakers can also be connected to many non-Siemens
systems via these communication networks.
Furthermore, local visualization on the DSP800 display can be implemented with the
COM800/COM100 breaker data server.
Example: Configuration of the COM800/COM100 breaker data server with a 3VA-line of
three 3VA UL molded case circuit breakers and with connection to the power monitoring
software powermanager (left), to the DSP800 (center) and to the commissioning and service
software powerconfig (right).
