4. Address assignment of the output modules:
After the (4-bit rounded) addresses of the valves
the digital outputs must be addressed.
– Assign the addresses in ascending order without gaps.
– Counting begins on the node from
right to left .
– Counting on the individual modules is made from the
top to the bottom.
– Digital output modules occupy 4 or 8 addresses.
Inputs
1. The address assignment of the inputs does not depend on
the outputs.
2. Address assignment of the input modules:
– Assign the addresses in ascending order without gaps.
– Counting begins on the node from right to left.
– On the individual modules from the top to the bottom.
– Input modules occupy 4, 8, 12 or 16 addresses.
3. Status bits:
The address assignment of the status bits depends on the
fitting variants of the inputs and the configuration.
The following always applies:
– The status bits are only available if input modules
are connected to the valve terminal and are configured
– Addressing
The status bits are transmitted to the four highest-
value positions of the configured address range.
