What is the maximum binding count per TGML graphic when polling OPC tags?

Issue

What is the maximum binding count per graphic when polling OPC tags?

Environment

Vista 5.1.X

TGML graphics

Vista OPC client

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 vista 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?
