The action detects the address of the I/O tag defined by the
parameter pointIdent. Address is represented by two strings (adr1_Txt, adr2_Txt).
If the detection of an address is successful, then the value of the
parameter retIdent_Int is 0 and the parameters adr1_Txt, adr2_Txt
get the particular values.
Example
BEGIN
INT _retIdent
TEXT _adr1, _adr2
GETPOINTADR M.bod, _adr1, _adr2, _retIdent
IF _retIdent = _ERR_NO_ERROR THEN
MESSAGE "Address of I/O tag M.bod:" + _adr1 + ", " + _adr2 ON srvskol1v.HIP
ELSE
MESSAGE "Failed to find the address of I/O tag M.bod" ON srvskol1v.HIP
