Diagnostic code
One input byte (Fieldbus PLC to Fieldbus module) must always be defined for the whished states of fieldbus inputs.
(1 Byte)
whished state of fieldbus inputs
(1 Byte)
This byte must always be present, also if no
fieldbus inputs are used in the electric schema.
If the SAFEMASTER PRO system includes a fieldbus module, the SAFEMASTER PRO Designer report will
include a table with the I/O index for all the inputs, fieldbus probes and safety outputs used in the electric
circuit.
