SUMMARY
The AbvSpu provides functions to read and write process attributes (Status, measuring value, alarm information) as well as to control process parameters (limits, delay times, etc.).PARAMETERS (IN)
- obj (INT)
- Object Number
- wMask (WORD)
- Bit Mask
PARAMETERS (OUT)
- wSts (INT)
- Status
PARAMETERS (IN_OUT)
DESCRIPTION
GetSts() - Reads actual statusReturns the status of the object referenced by <obj>.
The actual status is ‘anded’ with <wMask> and returned by <wSts> (wSts:=obj.sts&wMask).
The function is defined for measuring points only.
- For MP-Objects the Status (obj.sts) is returned.
- For PV-Objecte of the types Bit/Byte/Word the measuring value (obj.val) is returned.
- In case of an error <wSts=0xffff> is returned.
- Possible Errors:
- a) Invalid Object Number
- b) Wrong Object Typ.
