I'm starting to look into transferring it. The biggest hurdle is the RS485 communication. The PVP7 is only Ethernet, so I would have to upgrade the SLC CPU to a 5/05, or have a different solution with a Micrologix networked to the SLC's I/O. In theory, with enough time, I could figure either one out. But I'm a little hesitant to jump on this train during a very busy time of year. I could go with a PVP6, but that will be obsolete this fall, and we're back at the beginning.
Paul: I just *knew* you were going to mention the Red Lion conversion. With the above issues, I might have to consider that. I'm just afraid of taking on too many things at once. ...and I'd really like to get good at this.
