Free selection of modules
The cyclic data can be configured in any way from the available modules. You can find more
information in the table provided in the section "Modules that can be plugged in for the
project" above.
Further individual modules without property bytes are available in addition to the basic types.
Basic type 1
Basic type 1 was implemented according to the LVSG profile of the PROFINET user
organization (PNO) and comprises four data blocks. These are preassigned such that they are
primarily suitable for use with a 3WA circuit breaker without metering function. The most
important currents of the phases are transferred.
The predefined data blocks cannot be modified.

Basic type 2
Basic type 2 was implemented according to the LVSG profile of the PROFINET user
organization (PNO) and comprises six data blocks which are preassigned for a 3WA circuit
breaker with metering function. Here only the average voltage values are transmitted.
The predefined data blocks cannot be modified.
