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
4addresses
Type 04−B
Single−solenoid sub−bases always occupy 1 address
Double−solenoid sub−bases always occupy
2addresses
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.
