Overview
The figure below gives an overview of how the "FB_XXXA" block works:
Adding data
Following a request by a positive edge at block input "WREC_INS", the system writes the block
input values for archiving to the user archive on the basis of the archive name, archive number,
etc. The values are simultaneously copied to corresponding block outputs to store the values
written in the clipboard until the next write operation.
