Pretty sure the DCS takes info from the many different points along the process. The PLCs are small processes along the machine as well.
On the demarc point, what piece of networking equipment would you suggest for point (B)? Not sure if a router, managed switch, or since I'll want all remote locations on a VLAN, maybe it could be an unmanaged switch.
In all honesty, I was wanting the plant network for the remote access. So the above mentioned point makes needing corporate access a null point. Although, if they ever wanted a PLC tech company wide I could see this option asked for. Maybe you could tell me if remote maintenance of multiple locations of a company is done. I understand OEM access, but just couldn't imagine a guy in a company maintaining multiple facilities PLCs remotely. Seems more like they'd just dispatch that person to facilities instead.
Unfortunately, migrating Delta V over to anything else I fear would cost far more than 20k. Its currently got all the hardware and software plus a 30+ year senior staff member to maintain it. I don't know enough about the DCS, but I do know they collect distributed I/O, control, collect data, and trend that collected data. Things I'm sure plant PAX is capable of, but the cost of equipment and training would be a hard selling point.
As long as I can do the control/compactlogix on the VLAN as a datacollector, then if routing is all that is required to take a 192.168.100.xxx/255.255.255.0 address to a 10.20.0.xxx/255.255.254.0 address then sure. The delta V is basically treating the field PLCs as a remote I/O point. If I can slip things like Plant PAX in and slowly show its benefits would be about the only approach I can take. The fact that its free is a huge plus.
