This is another PLC that's been trucking along for the past 25 years.
I replaced the processor in this about 9 years ago because the serial port to the PV died. It's been hanging on chains for a long time because this is on an outside platform that vibrates really bad, and this was the solution they came up with.
They replaced the PV on this a lot of times. I don't have pic's of that, but I took a few apart at the shop and made a good one out of that and replaced it.
This will all be brand new in a few months.
I still like the shiny green fuses tho...
This is at a former customers facility from a company I use to work for, but I don't work for that company, but also looks like I'm it for the upgrade.
