Good morning Gentlemen,
This is my first post and I need some serious advice.
Firstly I want to say I am not a PLC programmer nor do I wish to ever be one, I am a process Engineer that works for a small Systems Integration company in Ireland.
I got assigned to commissioning a water treament system in a Pharma plant and I've managed to make a really big mistake.
As part of a validation test I was required to shut down the PLC to demonstrate a system shutdown. THe test worked but what I didnt realise was that when the PLC was in "Program" mode it retained its outputs. I somehow left a steam valve opened over night which managed to cause a 15,000L tank to crack resulting in an employee inflicting serious scaulding. Now my boss says its my fault and I better have a good excuse.
The guy who wrote this program has since left the company and I cannot contact him.I asked a guy who works in Automation to have a look at his program and he said its awful, no structure to it and the entire program written in a single routine with no comments and over 100 warnings. Is this my fault? Was the PLC faulty or was it the steam valve? Where can i find documentation on this PLC?
