How do I bring data to 800xA HMI from Wonderware Tag Server
The requirements are to bring values from an existing Wonderware Tag Server to 800xA HMI Screen.
Approximately 4000 values.
It will required to historize them too.
A specific server for OPC Connection with WW will be introduced and named as 800xA 3rd Party OPC Connectivity Server. This server with 2 NIC Cards: one NIC for 800xA Redundant Client/Server Nwk and one NIC Card to communicate with Wondwerare Tag Server thru a CISCO firewall.
Planing to use OPC tuneller.
Any commments to this implementation?
Am I missing something?
Is it a good practice to have dual home server or to be connected directly to Client/Server network and form there access the tunneler?
Any special licenses required in 800xA for this to work (apart of tag licensing)?
You don't need any special license and the configuration make sense. I would also recommend to use a tunneller, without that you may get problems to reconnect after lost connection. If you want to connect to a redundant 800xA network you will need two NIC's for that, in total 3 NIC's.
