Remarks:
1
)
In AC500 the following interface identifier applies:
"-" = Diagnosis via bus-specific function blocks; 0 ... 4 or 10 = Position of the
Communication Module; 14 = I/O bus; 31 = Module itself
The identifier is not contained in the CI512-ETHCAT diagnosis block.
2
)
With "Device" the following allocation applies:
31 = Module itself or ADR = Hardware address (e. g. of the DC551)
3
)
With "Module" the following allocation applies dependent of the master:
31 = Module itself (Module error) or Module type (1=AI, 2=DO, 3=AO; channel
error)
