select valve

With the system parameter [Select valve] it is possible to individually select valves for the control pro-

cess. Here it is possible to store all valves in the valve selection or to limit this to individual valves or

valve combinations (e.g. V1, V4, V5 and V7). It is also possible to query which valves are selected. The

valve selection is transferred as a decimal value originating in a binary code. Each bit of the binary

code represents a valve from right to left.
