Basic rules for addressing
Inputs and outputs
The address assignment of the inputs does not depend on
the outputs.
Counting does not depend on the position of the field bus
node (the field bus node counts as 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 function modules (word−
orientated, in preparation)
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 diagnostic interface follow the
input/output bits as from the next word
Please note
If two addresses are assigned for one valve location, the
following applies:
lower−value address: pilot solenoid 14
higher−value address: pilot solenoid 12
