Communication modules
The circuit breakers utilize an innovative, modern communication concept.
The basis for this concept is the communication-capable trip unit of the ETUs of the 6-series,
the metering function, and the different communication modules.
The terminal strip provides space for two communication modules. It is thus possible to
transmit data simultaneously to two different communication networks or communicate
redundantly on one network. The following communication modules are available for this:
● COM040 (PROFIBUS DP)
● COM041 (PROFINET IO)
● COM042 (Modbus TCP)
● COM043 (Modbus RTU)
● COM044 (IEC 61850)
You can find additional information in the 3VA Communication System Manual
(http://www.siemens.com/3VA-Documentation).
You will find information about the entire communication system, the ordering options, data
structures, and installation instructions, and the Modbus data structure as an Excel file on
the Internet at Siemens Online Support
(https://support.industry.siemens.com/cs/document/109750691/3wl10-
kommunikations%C3%BCbersicht?dti=0&lc=en-WW).
Digital I/O module IOM040
These modules are suitable for all electronic trip units of the 6-series.
The digital I/O modules IOM040 provide two input and two output contacts for control and
remote signaling of alarms and tripping of the circuit breaker. They can be used for the
electronic trip units with display (6-series). Via the display of the ETU or the powerconfig
software, default settings of the inputs and outputs can be selected and configured.
Ready-to-close signaling switch for communication (COM RTC)
The ready-to-close signaling switch COM RTC provides the same information as the ready-
to-close signaling switch RTC, see Section Auxiliary, alarm, and signaling switches
(Page 105). It is used to query whether the circuit breaker is ready to close.
Unlike the RTC signaling switch, whose signals are available at the auxiliary conductor
terminal system, the signals of the ready-to-close signaling switch COM RTC are forwarded
via the communication link.
Actuator module (COM ACT)
The actuator module (COM ACT) is a communication link for the remote operation of
auxiliary solenoids (CC/ST). With the actuator module, the circuit breaker can be opened
and closed by remote access.
