2.1.1 Ascertaining the address range

2−4
Ascertain before configuration the exact number of available
inputs/outputs. Depending on what you have ordered, a CPX
terminal comprises a different number of I/Os.
Please note
Note that a CPX terminal provides status bits or an I/O
diagnostic interface, depending on the setting.
The status bits must be treated like inputs and occupy
an additional 8 input addresses.
The 16 bits of the I/O diagnostic interface must be
treated like inputs and outputs. They occupy an addi
tional 16 input addresses and 16 output addresses.
If the PCP channel is configured, an additonal 16 input
addresses and 16 output addresses are occupied.
The maximum possible extension to the CPX terminal is
limited to 96 inputs and outputs.
The I/Os will be assigned automatically within the CPX
terminal.
