Hi, I'm looking for advice, is there any way to take a snapshot of all the registers, inputs, outputs etc. of a plc? It would be a great help for fault finding to be able to identify what contact was not made which caused a machine to stop. Generally we need to keep production running so it's a case of a quick check then hit reset and away we go, we don't have the luxury of being able to stop in the vfault condition and investigate. All suggestions welcome (Running Mitsubishi) Thanks
