How to exchange or share data between any two 800xa or 1190 Nexus systems
System 800xA V3.1
It is desired to share data between two systems, an 1190 Nexus system and an 800xa DCS system (a power house application). The two systems are on separate networks. They have an OSI PI server / application that is connected to both system.
The configuratiion at this installation is that there are two systems that are on independent Master networks, the paper machine being an 1190 Nexus system with an AC450 and Advant Stations, and the other system an 800xA DCS located in the powerhouse. There is an I/O point in the 800xA system, a water level input, that is sent to an OSI-PI Historian Server, The operators on the paper machine need to see this water level data point on the Advant Station. To accomplish this the OSI-PI server needs to send this data point to the AC450 via the Accuray Object Servers' Data Dictionary. The water level data point (or Tag Name) needs to be defined in the Data Dictionary. This wil then translate the OIS-PI server name to the tag name (needs to be defined) in the AC450 data base. This AC450 tag will then be displayed on the Advant Operator station.
