OSCAT BUILDING 功能块 BLIND_NIGHT 似乎不起作用

如何解决OSCAT BUILDING 功能块 BLIND_NIGHT 似乎不起作用

我遇到了 BLIND_NIGHT 问题。这个功能块在我的情况下似乎不起作用。日落时分我已经连接到 PLC 什么也没发生 我的代码如下所示：

FUNCTION_BLOCK Blind
VAR_INPUT
   xBlindDown: BOOL;
   xBlindUp: BOOL;
   xAutoSunset: BOOL := FALSE;
   xAutoSunrise: BOOL := FALSE;
   tSunsetoffset: TIME;
   tSunriSEOffset: TIME;
END_VAR
VAR_OUTPUT
   xBlindControlUp: BOOL;
   xBlindControlDown: BOOL;
END_VAR
VAR
   BlindInput: OSCAT_BUILDING.BLIND_INPUT := (SINGLE_SWITCH := FALSE,MAX_RUNTIME := T#25S,MANUAL_TIMEOUT := T#60M,MASTER_MODE := TRUE,IN := TRUE);
   BlindControl: OSCAT_BUILDING.BLIND_CONTROL_S := (T_UP:=T#20S,T_DN:=T#18S);
   BlindNight: OSCAT_BUILDING.BLIND_NIGHT;
   BlindSecurity: OSCAT_BUILDING.BLIND_Security;
   
   SunTime: OSCAT_BASIC.SUN_TIME := (LATITUDE := rLatitude,LONGITUDE := rLongitude);
   CurrentDateTimeUTC: DATE_AND_TIME;
   CurrentDateUTC: DATE;   
END_VAR

这是代码：

CurrentDateTimeUTC := FuGetDateAndTime();
CurrentDateUTC := TO_DATE(CurrentDateTimeUTC);

SunTime(UTC := CurrentDateUTC);

BlindInput(
   POS:= BlindControl.POS,S1:= xBlindUp,S2:= xBlindDown,);

//GVL.xInit is a global variable which is set to true after first PLC cycle
//this switch of IN state is required to stop moving of blinds after a power failure of PLC update
IF (GVL.xInit = TRUE) THEN
   BlindInput.IN := FALSE;
END_IF

BlindNight(
   UP := BlindInput.QU,DN := BlindInput.QD,S_IN := BlindInput.STATUS,PI := BlindInput.PO,DTIN := CurrentDateTimeUTC,SUNRISE := SunTime.SUN_RISE,SUNRISE_OFFSET := tSunriSEOffset,SUNSET := SunTime.SUN_SET,SUNSET_OFFSET := tSunsetoffset,E_NIGHT := xAutoSunset,E_DAY := xAutoSunrise
);

BlindSecurity(
   UP := BlindNight.QU,DN := BlindNight.QD,S_IN := BlindNight.STATUS,PI := BlindNight.PO
);

// in order to stop moving blinds after a power failure or PLC update we need to check if PLC has been initialized
BlindControl(
   UP := BlindSecurity.QU AND GVL.xInit,DN := BlindSecurity.QD AND GVL.xInit,S_IN := BlindSecurity.STATUS,PI := BlindSecurity.PO
);

xBlindControlDown := BlindControl.MD;
xBlindControlUp := BlindControl.MU;

我也遇到了一个问题，即断电后百叶窗会自动打开 - 我不希望这就是我引入 xInit 全局变量的原因，该变量默认为 false 并在第一个之后设置为 true PLC循环。多亏了 PLC 的这种重启，百叶窗不会向上移动。 我正在使用 IN := FALSE for BLIND_INPUT 测试整个代码，但它也没有帮助，BLIND_NIGHT 不起作用。

您发现这里有什么明显的问题吗？
