Important: Pro-Set 600 software downloads all command blocks when
your PLC-5 processor enters run mode after a valid MCC block is
accepted. All programming errors reported in SYS62 (N40:214) are
referenced to the MCC block until SYS01-B08 = 1.
Correct Any DataĆentry (Programming) Errors in MCC
Upon receipt of the MCC block, the QDC module tests data for data-entry
errors, such as a value out of range. When it detects an error, the QDC
module halts operation until you correct the error. For a complete list of
error codes to help you correct a programming error, refer to Section 2 of
the Plastic Molding Module Reference Manual, publication 1771-6.5.88.
You must correct errors by entering the changed configuration values into
your PLC-5 data table and downloading the new values to the QDC
module as outlined above. Pro-Set 600 software continues to attempt to
download the MCC block to the QDC module until an MCC block is
accepted and the QDC module returns SYS01-B08 = 1.
Important: The QDC module must receive a valid MCC block before you
can download additional blocks.
