Can anybody help me? We have a newly installed slc500 run by rslogix 500 Professional. During trial runs on our conveyor, the plc unit is in a "RUN" mode with the pilot lamp lit beside the "RUN" which is OK. When we try it again it shifted to "FLT" with the red light blinking beside it. What is the cause and how can we solve the problem? We tried to turnoff the power supply to the plc and turn it again but still the "FLT" is blinking. The conveyor doesn't work anymore. Can anybody help me? Thanks a lot.
