Table13: Outputs
Name Unit Value range Description
fYAnalog none LREAL Analogue control value.
bYPWM none [TRUE,FALSE] Boolean output, pulse width modulated.
bYDig none [TRUE,FALSE] Boolean output of a two-point controller (TRUE control
value 100%, FALSE control value off)
bYDigPos none [TRUE,FALSE] Boolean output of a three-point controller (TRUE control
value 100%, FALSE control value off)
bYDigNeg none [TRUE,FALSE] Boolean output of a three-point controller (TRUE control
value -100%, FALSE control value off)
dwAlarm none DWORD Alarm signals (see ENUM ...)
iState none INT Present controller status (see ENUM ...)
bError none [TRUE,FALSE] If an error is present, then bError is TRUE.
iErrorId none INT If bError is TRUE, then iErrorId provides an error code
(see ENUM ...)
