4. Commissioning
4−8
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.
