How to reset an S5 PLC.
I'm adding this to the forum because I always forget this sequence...
Siemens S5 reset instructions
1. Put the plc into stop mode using the physical start/stop switch on the plc
2. Now press the switch below the start/stop button towards the Overall Reset position and hold it there.
3. With the bottom switch held at overall reset position, switch the start/stop button from stop to start and then back to stop twice. While still holding the bottom switch at overall reset wait for the stop led to flash.
4. Release the overall reset and your PLC should be reset.
