Start up

Various initialization processes of the ISG-MCP run through in the event of a cold start of the PLC program.

During this initialization phase, AXSD is in the "State" 0 ("INIT_STATE").

During this phase, all FBs of the MCP behave passively, i.e. they do not have write access to the HLI. If an FB sends a command before the initialization phase has ended, e.g. because of initialization of an "Enable" input with "TRUE", the FB reports the error 16 ("FB_ERR_TNA_INIT_STATE").
