Hello Team,

I am using S71516 PLC with Zenon 7.60. I have created one driver instance for PLC and no of tags is 1600.
Some times i am facing an issue that Tag write from zenon was taking more time to update in PLC Data Block and this time is not consistent.

I need support on below points.

1. How to make Zenon to PLC tag write faster either doing settings in PLC or Zenon?
2. Is it possible to create more than one driver instance for a single PLC to get faster read and write between zenon and PLC. It is recommended or not?

Earlier reply is appreciated.
