Communication of the ETUs of the 6-series (optional)
The electronic trip units of the 6-series can be expanded with communication connections
because of their modularity. Depending on the communication modules used, the following
protocols are available:
● Modbus RTU via RS485
● Modbus TCP via Ethernet and other IP communication
● PROFIBUS DP
● PROFINET IO
● IEC 61850
Communication is used for software integration into
● powerconfig for parameterization and maintenance
● powermanager for power monitoring and operational monitoring
● Totally Integrated Automation TIA for automation and process integration
● Energy automation
Metering functions of the ETUs of the 6-series (optional)
For the electronic trip units of the 6-series, there are two metering function modules:
● MF Basic
● MF Advanced
These modules allow determination of the following additional measured quantities:
● Voltage
● Power
● Energy
Additional features of the MF Advanced version:
● Implementation of the enhanced protection functions that are based on the variables
voltage and power
● Power supply of the ETU from the busbar voltage (for line voltages above 85 V) and
therefore also activation of further functions such as powering the external ground-fault
neutral transformer Gret, or the making current release, without an external power source
● Implementation of the Rc residual current protection function via an external summation
current transformer
