6.7.1 Use of actual value and set value inputs as digital
inputs
The actual value and set value inputs can be used as digital
inputs under the following conditions:

In order to address the two digital inputs "In W" and "In X" a
resistor (R=1.2KΩ±5%) must be connected in series with the
input according to the wiring diagram. The switching levels are
> 11mA for a High-Signal and < 8mA for a Low-Signal.
