16.2.20.1 Arithmetic function
This function extension is available from version 06.00.00!
The integrated arithmetic function allows for easy arithmetic conversion of the process
value to be written or which was read into the format of the target parameter via
parameterisable factors and without the need for an additional arithmetic FB.
In C01093
, the interpretation of the wInHWord and wInLWord inputs can be set to be
able to write to parameters:
C01092/1...3 Error status
•If bFail = TRUE:
Error status is displayed.
•Subcode1 = LS_ParReadWrite_1
Subcode 2 = LS_ParReadWrite_2
Subcode 3 = LS_ParReadWrite_3
0No error
33803 Invalid data type (e.g. STRING)
33804 Limit violation
33806 Invalid code
33813 No element in the selection list
33815 Writing of the parameter not
permitted
33816 Writing of the parameter only
permitted if controller is inhibited
33829 Invalid subcode
33865 No parameter with subcodes
