I recently made a small modification to a program for a SLC 5/05. It reads 6 elements from a "F" data table in a ML1100. It reads F8:61 to F8:66 from the ML1100 and puts the values into F8:11 to F8:16, respectively. There is no problem with the read.
However, when I open the data table to view the contents, RSLogix (7.10.00 (CPR 7))freezes - every time. Actually, it freezes when I try to open any data table in the program. This has never happened before and it doesn't happen if I open the program with RSLogix another laptop (8.20.00 CPR 9). I can view data tables from any other compatible PLC with either version RSLogix and they work fine, so there must be some strange "bug" that was introduced when I added the additional MSG instruction to read from the ML1100.
I've changed the logic so that the MSG only reads 1 element, and I get the same result.
When I download the old version (pre-MSG), I can view data tables again.
If I have time later, I'll eliminate the read MSG and try writing the values from the ML1100 to the 5/05 to see if it still locks up.
Until then... Any suggestions?
