3.
Locate the data file for storing the MCC block. PLC-5 data table
word addresses are listed on the worksheets.
4.
Enter the value for each word and bit.
When you enter bit selections in words prefixed with file identifier B
(example: B34), the PLC-5 processor automatically switches the radix to
binary format so you can conveniently enter binary data.
Download MCC Parameters
To download the MCC block to the QDC module, switch the PLC-5
processor from
PROGRAM
mode to
RUN
mode. Pro-Set 600 software
downloads the MCC to the QDC module for you.
Important: You can verify that the MCC block was successfully down-
loaded or you made a programming error by evaluating the following
words that Pro-Set 600 software continuously reports to the PLC-5
processor.
If:
And:
Then:
SYS01ĆB08 = 1
(B34/8)
N/A
QDC module accepted a valid MCC.
SYS19ĆB00 = 1
(B34/288)
SYS61 = 1
(ID code for MCC block
stored in N40:213)
You made a programming error in MCC.
Read the error code in SYS62 (N40:214), and
look up the error in Section 2 of the Plastic
Molding Module Reference Manual (pub. no.
1771Ć6.5.88).
Important: Pro-Set 600 software downloads all command blocks when
your PLC-5 processor enters run mode and after a valid MCC is accepted.
All programming errors reported in SYS62 (N40:214) are referenced to the
MCC until SYS01-B08 (B34/08) equals zero.
Correct Any DataĆentry Errors
Upon receipt of 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 errors, 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 is accepted
and the QDC module returns SYS01-B08 (B34/08) equal to 1.
