We are discussing design specifications for a combined cycle plant, and want to control the operator environment, including but not limited to a "high performance" HMI.
Assuming that GE still delivers their HMI like Henry Ford delivered the model T ("you can have any color as long as it's black"), the goal is to put an HMI that we can control on top of everything in the facility, including the Mark VI should GE be part of plant (decision not yet made.)
I would like to avoid the classic interface to the GE HMI. Interfacing directly to the control system, like the GE HMI does, is preferred. Redundancy is also preferred. Any suggestions on interfacing?
Also I heard last week that GE charges for "every alarm" that is subscribed for. I would think that the proper term would be "every tag" and not simply just for alarms. Is there any truth to this?
Finally, any other pitfalls to avoid?
Thanks, John
