Message: '<value>' is not a valid bit number for '<variable>'
Possible error cause: Attempted access to a bit that is outside of the range for a data type.
Error correction: Use a bit value for the bit access that is lower than the number of bits in the data type of the variable.
Example of the error:
PROGRAM PLC_PRG VAR test1: WORD; test2: BOOL; END_VAR test1 := test2.17; --> C0003: '17' is not a valid bit number for 'w'
