I would leave it up to the contractors, engineers and such but they were already here. They put in a photo eye and worked to get the line to prevent jams. After a few attempts they simply gave up and ripped out all the equipment. We made numerous attempts over the past year for them to fix it but they haven't even looked at it again. Our line has 50+ major issues and we spent millions for the install. I'm a first year tech and I've been fixing things that 3+ of their techs could not.
So basically its up to me or it won't get fixed.
I could wash my hands of it but when someone gets hurt I'm not really going to be worthy of this position.
As for the system, there are surely better plc things I could do but access to this will not be given by my company. Rightfully so as I could make things much worse. I think designing a little module would be the most practical or finding a similar solution on the market is good too.
To be honest it might take me a few years more to do this. I have such a mental block with this kind of work.... I miss PHP!!!!!! I've learned a bunch of random facts from Dave and so far I've only blown 1 power supply
BTW. We pass OSHA inspections every time.
