Information about the movement test can be found in section 3.2.1.
As long as the movement test has to be carried out (bit 0 = 0), the controller is not enabled.
SCON.ENABLED = 1 only indicates that movement enable is available for the movement test, the
valve is only operated if it is controlled.
With a starting edge for another task other than the movement test the fault E14 Movement test not
executed" is issued.
FCT indicates the status Movement test" in the Advanced data" frame. The LED turns green when
the parameter value has the status (binary, byte 1) xxx0 1111.
If the hardware was exchanged, the movement test is automatically reset by the CMAX (example:
exchange valve and change back again). This is not reversible.
The movement test staus can be reset or skipped with PNU 1192:07.
