Before configuring, ascertain the exact number of available
inputs/outputs. Dependent on what you have ordered, a CPX
terminal comprises a different number of I/Os.
The I/Os will be assigned automatically within the CPX
terminal (standard setting). The following applies to inputs
and outputs:
– The address assignment of the inputs is independent of
the outputs.
– The counting mode is independent of the position of the
bus node. The bus node counts as a module with 0 or 8
inputs or 16 inputs and outputs, depending on the setting
of DIL switch 5 (è section 1.2.2).
– Counting is from left to right, in ascending order without
gaps.
Note
– Observe that a CPX terminal provides status bits or an
I/O diagnostic interface, dependent on the setting.
– The status bits must be treated like inputs and occupy 8
bits in the Transmit PDO 4 (standard setting).
– The 16 bits of the I/O diagnostic interface must be
treated like inputs and outputs. They each occupy 16
bits in the Transmit and Receive PDO 4 (standard set­
ting).
