Basic rules of addressing
With mixed fitting, the address assignment of the valves, digi-
tal I/O modules and status bits is taken into account.
Outputs
1. The address assignment of the outputs does not depend
on the inputs.
2. Address assignment of the valves:
– Assign the addresses in ascending order without gaps.
– Counting begins on the node from
left to right
.
– Maximum 26 valve solenoid coils can be addressed.
Type 03:
– Single-solenoid sub-bases always occupy 2 addresses
– Double-solenoid sub-bases always occupy
4 addresses
Type 04-B
– Single-solenoid sub-bases always occupy 1 address
– Double-solenoid sub-bases always occupy
2 addresses
3. Round up to 4 bits: The following distinction is made:
a) If the number of valve addresses can be divided by 4
without remainder, continue with point 4.
b) If the number of valve addresses cannot be divided by 4
without remainder, you must round up to 4 bits because
of the 4-bit orientated addressing. The bits thus
rounded up in the address range cannot be used.
