Ok, I re-opened the topic so I'll try to handle this debate. My understanding of ArchestrA is that it is a common denominator for your low-level process engineering needs, bringing together DCS, PLCs and stuff. InFusion ECS is a much broader product with other goals (like Plant Management) which have nothing to do directly with your process system but it does help you with your whole Business Process. Am I right here, Invensys?
