B.4
Parameter assignment and structure of the parameter data records
of the digital on-board I/O
Parameter assignment in the user program
You have the option of reassigning parameters for the digital on-board I/O in RUN (for
example, values for input delay of individual channels can be modified in RUN without
affecting the other channels).
Changing parameters in RUN
The parameters are transferred to the digital on-board I/O via data records 0 to 15 with the
WRREC instruction. The parameters set with STEP 7 (TIA Portal) are not changed in the
CPU, which means the parameters set in STEP 7 (TIA Portal) will be valid again after a
restart.
The parameters are only checked for plausibility after the transfer.
Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the digital on-
board I/O continues operation with the previous parameter assignment. However, a
corresponding error code is written to the STATUS output parameter.
You will find a description of the "WRREC" instruction and the error codes in the STEP 7
(TIA Portal) online help.
