For FB_VGC_2S.TcPOU Please set the DP interlock to be true by default so the GUI screen shows the correct logic

[slacAdpai]

FB_VGC_2S.TcPOU should set the differential pressure to be true by default because it is not even checked in the interlock:

(* As long as the differential pressure is less than 30mbar, the valve is allowed to open )
IF rDiffPress <= rDiffPressAllowed AND i_stUSG.xPRESS_OK AND i_stDSG.xPRESS_OK THEN
iq_stValve.xDP_OK := TRUE;
ELSE
iq_stValve.xDP_OK := FALSE;
( If the differential pressure is exceeded, even when the valve is open,
the state is unexpected and triggers a fault, because it suggests that something
is wrong with the valve, or gauges or mapping or there is a major leak on one side.*)
iq_stValve.eVGC_State := ERR_DiffPress;
iq_stValve.xERR_DifPres := TRUE;
