Address Assignment Of The Cpx Terminal - Festo CPX-FB6 Manual

2.1.2 Address assignment of the CPX terminal

2-14
Basic rules for addressing
Inputs and outputs
– The address assignment of the inputs is independent of
the outputs.
– Counting mode does not depend on the position of the
bus node (the bus node counts as a module with 0 inputs
and 0 outputs)
– Counting is from left to right, in ascending order without
gaps
– Sequence:
– Input/output words of the analogue modules,
– Input/output words of the technology modules (word-
oriented),
– Input/output bits of the electric inputs and outputs
(including valves),
– The 8 status bits follow the input bits as from the next
byte,
– The 16 bits of the I/O diagnostics interface follow the
input/output bits as from the next word.
Note
If two addresses are assigned for one valve position, the
assignment applies:
– less significant address: pilot solenoid coil 14
– higher-value address: pilot solenoid coil 12
