Support Questions / Re: Advanced HMI driver performance problem
« on: June 15, 2023, 12:09:38 AM »
Yes, We tried with the new version but same problem was coming.
We are little confuses is it driver side problem or networking?
Because when we are doing the internal testing PLC to PC it works fine.
but when we are deploying At client side facing a problem.
On client side main PLC is connected to .net app , HMI and one more PLC.

Support Questions / Advanced HMI driver performance problem
« on: June 14, 2023, 07:15:29 AM »

We are using Micrologix 1400 PLC.
Case 1: when testing .net the application with only .net application to PLC(PLC is of Type B and firmware is old) the performance was good.
Case 2: when HMI + .net application + Second PLC( which communicates with other plant hardwares )+ Main PLC(firmware is latest and Type C plc) to which hmi and .net app communicate . In that case the Advanced HMI driver reading/writing slow downs the app performance.

In .net application , we have created 3 client as follows
1.Alarm
2.Event
3.All screens

We created three clients which are communicating with the main PLC.
Mostly we are reading addresses  in Block but for boolean files in some cases we are unable to read the block address.
In alarm we are reading the 120 tags on 500 msec time frequency.
In event 50 tags in 5 sec
in screen 100 tags in 1 or 2 sec.
 we are facing bad performance in client side.

Please let us know the solution for the same.
