Troubleshooting Error Messages in CX-Net Data Link Table Check Section 9-4

Example Display of Error List

Note (1) If any errors (except for warnings) are detected during the table check performed when transferring data link tables, the data link tables will not be transferred even if the OK Button is clicked. Remove the cause of the error and then transfer the data link tables again.

(2)Messages (in the Contents field) preceded by “Warning,” indicate a warn- ing, not an error that will prevent operation continuing. Check the contents of the message, and confirm that the intended settings and allocations are correct. Click the OK Button to transfer the data link tables without any changes.

(3)The following two messages indicate warnings for CS/CJ-series Control- ler Link Units with unit version 1.2 or later and errors for CS/CJ-series pre-Ver. 1.2 Controller Link Units.

Node XX Node size:

Warning: The total send and receive size of ** exceeds 12000. Node XX Area Overlap:

Warning: Link memory areas 1 and 2 are both set to – [Area]
