Description
2.10 Communication
①
②
Because the circuit breaker is designed for up to two communications modules, it can be
integrated into the communication environment with two different protocols. For example,
simultaneous connection of a fieldbus for automation or remote control applications (incl.
parameterization and remote switching) and Modbus TCP Ethernet communication link for
communicating measured values for efficient and safe power monitoring.
For the remote control switch of the 3VA27, you require the version of the stored energy
mechanism to be able to connect the device via the closing coil / shunt trip and Com Act
when the spring is charged. The automatic spring charging motor is recommended for this.
(Info: Opening the circuit breaker is always possible even when the spring is not charged.)
Communication applications
• Parameterization and configuration
– With the powerconfig software (as of Version 3.9)
• Energy management
– Metering function MF Basic / MF Advanced
– Remote access and remote switching
– Integration in powermanager and TIA
