Addressing
Note
– Addresses may be shifted if the valve terminal is extended.
– If a monostable 5/2-way valve (requiring an address) is mounted on a valve
position that supports the actuation of 2 addresses, one address remains
unused.
6.1 Addressing rules:
– Address assignment is in ascending order without gaps, from left to right.
– Address assignment is independent of whether the manifold sub-base is
equipped with a valve or a cover plate.
– Depending on the integrated electronics module, a valve position, comprising a
manifold sub-base with electronics module, occupies the following number of
addresses:
Colour of the electronics module Number of occupied addresses/valve position
Grey
1
Black
2 – Less significant address for coils 14
– Higher-value address for coils 12
Fig. 4
– A supply plate does not occupy an address (blue electronics module).

1)
Requirement: valve terminal completely mounted, plug connector inserted. Observe that connected
devices might only satisfy a lower degree of protection, a smaller temperature range, etc.
2)
The valve terminal is intended for use in an industrial environment. Measures for interference suppres
sion may need to be implemented in residential areas.
3)
Use connecting cables with a length of maximum 30 m.
4)
The operating voltage supply is provided via the CTEU bus node or IO-Link master. The load voltage
supply is through the CTEU bus node or, for IO-Link, through a separate feed. Separate fuses are re
quired for operating and load voltage.
