2.1.7 Bus configuration without CMD software

2-38
Logical addressing
In the case of the bus configuration without CMD software,
the following specifications must be known or ascertained for
each bus station. Configure the CPX terminal as follows:
ID code (Ident. code)
•
– CPX terminal only with outputs
CPX terminal only with inputs: ident. code 2
–
– CPX terminal with inputs and outputs
– CPX terminal with PCP channel: ident. code 243
1)
Solenoid coils and/or electric outputs
Process data channel:
•
– Calculate the number of I/Os per valve terminal.
The number of inputs and outputs must be rounded
up to the next word limit.
If the number of input bits differs from the number of
output bits, the greater number is in each case decis-
ive for entry of the process data channel bits.
– Observe that the status bits occupy an additional 8
inputs.
– Observe that the I/O diagnostics interface occupies an
additional 16 inputs and outputs.
– Observe that the maximum number of process data
bits is reduced by 16 inputs and outputs when the
PCP channel is activated.
– Assign logical IN and OUT addresses to each station.
