3 Controlling the valve terminal
Use a uniform method of control. Preferably all control
signals should be positive−switching (1−switching), other
wise all control signals negative−switching (0−switching).
Mixed mode control is not permitted.
3.1 Address assignment of the valves
Assign the addresses in ascending order without gaps.
Counting begins from left to right, but on the individ
ual valve positions from right to left.
A valve position occupies 2 addresses on the manifold
block and Bi−expansion block, even if it is fitted with a
blanking plate. On the Mo−expansion block 1 address
will be assigned.
In the case of valves with two pilot solenoids, pilot
solenoid 14 occupies the lower−value address and
pilot solenoid 12 occupies the higher−value address.
In the case of valves with only one pilot solenoid on
Bi−blocks, the higher−value address remains unused.
