Zenon to Siemens PLC Tag writing delay

Zenon to Siemens PLC Tag writing delay

Hello,

In my project i have used Siemens CPU 319 and it is connected with Zenon Supervisor. With PLC i have connected many devices via profinet and Zenon supervisor too. Total no of PLC tags is 4500. Here i have recipe (RGM) and datalogging to MSSQL using VSTA.

When i download a recipe (300 Tags) or write data (around 350 Tags) from zenon to PLC, at this time it is taking around 30 SEC to update the tag value in PLC.

Tags update from PLC to Zenon is taking 5 to 7 sec to update in zenon. I have prioritize the tag update time also. Normal - 300, highest - 100.

Please suggest how to get fast updation of tags between PLC and Zenon for both read and write. Requirement is tag updation should happen 1 to 2 sec between PLC and zenon.

What are the factors i have to check in software and hardware? Please suggest and need support on this.

Regards,

Dhanapal
