How to calculate the polling time at the netcontroller / OPC server?
How many nodes/ controllers can be put on each netcontroller to get to specific polling time.
- OPC Server
The OPC server was designed to be performance tuned.
It is hard to determine just how many controllers / polling time. It would be determined better by looking at the programming of the controllers, for example, Inputs / Outputs how many points in each group and the interval of the data that is required to be received.
The "OPC Server Guide" has performance options and guidelines on setting up an optimal system. You can also add another OPC server if you need to do load balancing.
