Hi,we have TI505-TI525 PLC to control Columbia block machine in our system and got a problem. As you know there 3 LED on the PLC module. these are;
RUN LED
PC GOOD LED
DC GOOD LED
One day, I tried to run the plant but RUN LED was not lighted. I reloaded the Tisoft4.3 program from PC to PLC then took the switch OFF then ON position but still was not RUN LED ON position. Could you tell me how to get RUN LED is ON and what to do to take RUN LED is ON.

Thanks

You must disconnect the battery. This clears the memory. This kind of error is usually the result of a parity error in the memory of the plc. I have seen this problem many times and this has always worked when I have encountered this problem.

I've seen this problem when an eeprom is on it's way out. Clear the memory, replace the eeprom and reload the software.
