Data only available in conjunction with the COM15 module
(BUS connection not required).
2)
Only possible with ETU76B.
✔ Available
-- Not available

Possible applications
Transmission of circuit breaker data to PROFIBUS DP or MODBUS and integration into
higher-level visualization systems possible
e.g. in PCS7, Power Management Systems, WinCC (incl. add-ons like the text message radio server)
-- ✔
Transmission of circuit breaker data and software (i.e. HTML pages with data) to a local output
device, or remotely through Ethernet/Intranet/Internet (without the possibility of integration into
higher-level visualization systems)
e.g. for monitoring, diagnostics, maintenance and parameterization of individual circuit breakers
✔ --
Utilization of the functionality of all CubicleBUS modules
e.g. configuration of the configurable digital output module, status check of the digital input modules,
diagnostics
✔ ✔
Transmittable circuit breaker data without integrated metering function
Device identification
Communication address, Article No., circuit breaker in delivery state, circuit breaker parameters
(size, number of poles, rated current module etc.), identification numbers, trip unit type,
free text for plant code and comments
