I am trying to increase the responsiveness of my main operator interface. Currently when, for example, something passes a sensor it is generally 2-4 seconds before it is registered on the screen. What I am ultimately trying to do is reduce that as much as possible. I have separated each PLC into it’s own scanclass which the gateway status page tells me runs at an average duration of about 4ms. The rate is 900ms.
If i reduce the 900ms rate the tag quality intermittently becomes unknown and the graphics flicker to indicate a bad tag? Is this normal behavior? How often should I be able to run a scan class? Should I be doing something else to speed up indication on my screens?
