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 plates from right to left.
A valve location always occupies 2 addresses, even if it
is fitted with a blanking plate.
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 one pilot solenoid, the
higher−value address remains unused.
