Powerservice software
If a laptop with the powerservice software is connected to an ETU of the 6-series, the
following data can be recorded.
That is the data log described above can be called up or the TD420 can be read out. In the
powerservice program, a high-resolution analysis of the 3-phase current and voltage curves
can be performed for fault analysis or to identify system anomalies.
The on-board buffer memory (= register) of the ETUs of the 6-series is constantly written to.
You can set up to two trigger points at which the memory is to be frozen with its symmetrical
time interval before and after this point or these points. You can also import simulated
current and voltage curves into the device with the powerservice software and then test and
document how it would respond. In this test environment, real test tripping is generated. In
this way, the software helps to find the optimized parameter settings for the user's
application.

Communication
The circuit breaker can be integrated into an industrial communication network via
communication modules for remote monitoring and remote operation of a circuit breaker.
The communication modules are used with the electronic releases of ETUs of the 6-series.
Its most important functions are power distribution and generator protection.
Depending on the communication modules used, the following protocols are available:
●
Modbus RTU via RS485 (COM042)
●
Modbus TCP via Ethernet and other IP communication (COM043)
●
PROFIBUS DP (COM040) (planned for 2019)
●
PROFINET IO (COM041) (planned for 2019)
Up to two different communication modules can be installed at the same time so that
connection to the communication systems is possible with different protocols.
The standards demanded of air circuit breakers in terms of their electrical and mechanical
properties, cost-effectiveness, and adaptability are increasing as a result of ongoing
