Vijeo Designer_UnityPro Channel Update Times

[Lewis_Red]

Hi Guys, Have a simple question. New with UnityPRo V6.0 and Vijeo Designer. Need to slow the update time to analog channels on the HMI so the readings are not changing rapidly and unuseable to the operator. Tried to increase the filter time in UnityPro to 3 & 4 but did not slow down. Any other ideas?

Filter time setting at analog channel is only couple or several plc scans.

On vijeo designer you need change scan group setting for variables that you want update slower.

First you need to add new scan group to io-manager.
Then navigate to variables and change scan group setting to this slower group.


Another method is to use filter code on PLC for analog measurements (smoothing/filtering)

You can try filter FV=FV+C(NV-FV) for analog channels.

FV= Filtered value
C= constant. The smaller the number the more dampening.
NV= New Value
