Issue
What is the maximum binding count per graphic when polling OPC tags?
Product Line
TAC Vista
Environment
- Vista Server
- Vista OPC Server
Cause
There is no limit to the number of OPC tags, but performance may be affected when a large number of binding are used.
Resolution
The load on the Vista server should be considered. E.g. datatypes and the update period:
- Does an outside air temperature tag need to be updated every 10 seconds or is 10 minutes maybe more appropriate?
- Can binary signals be combined into a single register?
