Hi Okie,
Not at this time. The P&I has a date of 1995 and it has 10 pages. I'm guessing that it is not a small system. It does chemical / solution make up control on a coil processing line. I see the usual compliment of level, flow, pressure & temperature monitoring and plenty of pump / heating controls.
The chemical supplier was contacted by a customer for an update proposal. They happen to be involved with one of my clients and so we have been talking a bit about options.
Right now, we are working to establish I/O count and degree of complexity required. Obviously, it is one thing to control solution temp and concentration, etc. and quite another to control the line movement.
Best Regards,
Bob A.
