Note
Error case
When reading variables from different channels or drive objects, or simultaneously from a
channel and a drive object, the following feedback message is output:
● "Error" == TRUE
● "State" == W#16#02
Note
To read a variable of the DOUBLE type from NC without adapting the format, an ANY pointer
of the REAL2 type must be specified in the target area (e.g.: P#M100.0 REAL 2). If the basic
program recognizes REAL 2 as the target type when reading a variable of the DOUBLE type,
the data is applied to the PLC data area as a 64-bit floating-point number.
