The meaning of the single bits in ru18 dig. input state is defined as follows:
Input state ID (can only be set by the input block)
Channel 1 from the safety mod-
ule
Can not be changed by the input
block
Channel 2 from the safety mod-
ule
1 means that the state of the input is set to active at the output of the processing
block of the digital inputs.
Selection of the input source
The source for the internal terminal state can be selected via the object di01 dig.
input src. sel.
Selection of the internal terminal state source
It can be selected from the 4 sources below for inputs I1...I8 and IA...ID.
The terminal block is always used as source for inputs STO-1 and STO-2.
The selection of the source is done for each input via 2 successive bits in di01 dig.
input src. sel. The meaning of this source selection is identical for each input.
