I work for a automotive parts manufacturer that is trying to remain profitable. We have a Johnson Metasys control system that controls our penthouses and two older chillers. We also have a Trane Tracer Summit control system (ver 10.04.0025) that controls our two newest chillers. Needless to say both are legacy systems. We are having issues now with the Arcnet cards in the Metasys PC's (Win95).
My question is this. Without upgrading the hardware in the feild, or the network they operate on, what in your humble but wise opinion would be the best way to integrate both of these into a single HMI?
What would be needed for hardware?
What would be the easiest software to configure, and will talk to both?
How do we choose something that will be around 5 years from now?
How about a recommendation of a reliable system integrater?
we are trying to upgrade a little at a time in order to keep costs down, yet the past culture in this UAW plant was to "buy from the big guys so they will take care of everything", and yet they don't (unless you want to pay through the nose). You all know the problems with dealing with both of these proprietary systems.
Any comments would be welcome. Thanks!
