New version 800xA V6.0 have any function like Honeywell DSA Protocol
In many oil & gas plant. As system experion of Honeywell they have function:
Distributed System Architecture (DSA) is the ideal solution for integrating processes when there are multiple units, control rooms or geographically distributed locations. With Distributed System Architecture, users experience a single, totally integrated system instead of several independent systems, while retaining the ability to autonomously manage each system. The result: optimum functionality and flexibility.
So I read 800xA also have but ABB cost one more server "provider" and "Subcriber"
Honeywell just enable function "DSA" without any more engineering like ABB. ABB 800xA must create and implement on "provider" and "Subcriber". If a system include many control rooms are complicated for ABB's solution.
Honeywell is simple.
One more thing: Server Experion of Honeywell support connect third party with 300.000 tags and many protocol also not limit channels. ABB only have function "PLC Connect" only support 25.000 tags and limit about 30 channels.
The ABB feature is Multi-System Inetgration. As far as you describe, the result is exactly the same.
- Confirm with your sales person but Honeywell typically, 1 value = 1 tag
- In ABB, 1 Faceplate = 1 Tag. Each faceplate has many values, typically 10 to 20, easily more.
