RedLotus Posted September 26, 2011 Report Share Posted September 26, 2011 Hi, I was trying to use the Jazz PLC as a mod bus slave and forced the following System integers in my program: SI 141 = #1 SI 142 = #100 SI 143 = #3 SI 144 = #2 SI 145 = #19200 SI 140 = #600 After I loaded my program to the PLC, I modified the program in the U90 Ladder and tried to reload it but it resulted in a communication failure. The comm parameters are perfectly matched and the cable does not seem to be at fault. Is this because of the program? If so is there any way I can delete the program via the keypad? I tried to stop the program using the Info button and tried to re-establish communications but that did not work. Is there any way to revert to Factory Settings? Is this step necessary in this case? I would appreciate it if someone could answer my questions. Quote Link to comment Share on other sites More sharing options...
