Title: Priority tag/address
Post by: joko markono on March 09, 2025, 01:23:07 AM

Hi,

First of all, sorry if this topic has been discussed before.
Is there a way to prioritise the plc address that i want to read because i have about 100 addresses to read and display. Some of them need to have faster update. I'm using OmronSerialHostlink.

Add a second driver instance to the form, set the PollRateOverride to how fast you want it to update.
For the controls that display the faster data, set ComComponent property to the driver instance that with the faster PollRateOverride

it works! Thanks Archie.
How many driver instance I can add for the same PLC unit and serial port?

There is no limit. They all route through one common data link layer so it does not create port sharing issues.
