Number of OPC Client Connections - System 800xA 6.0.2
Please, how can I check the number of OPC Client Connections avaliable or in use at the System 800xA (version 6.0.2)?
I imagine this is a controversial issue, as no one person could tell me how to verify it, but I have a customer that requested that information.
Thank you for attention.
Be specific .... OPC connections to what ?
There is one OPC-DA and one OPC-AE connection to the AC800M for each connectivity server connected to that controller.
Workplaces do not connect to the controllers. Each workstation has OPC-DA Connections to the Connectivity Servers and OPC-HDA connections to the History services.
Third party clients can be connected to either the Afw Surrogate Server or the AC800M OPC-DA server.
If you use third party PLC's, again there are only connections to the Connectivity Servers.
The 800xA system uses "OPC Connections" in many places to many different OPC servers. But it is designed to effectively share OPC data between the clients and minimise the number of connections required to a PLC.
What is it you really want to know ?
