Disconnect from driver instance in Runtime

[milosh]

Hi all.

I would like to know is there possiblity to quit/continue communication with some driver instance?

So I have driver S7TIA or S7TCP32 with 10 instances...

How to dynamically disconnect/connect from some of that instances.

I know for driver variable Start/Stop communication, but it disconnect/connect all driver (all instances).

Thanks a lot,
MK

you write that you have 10 instances, but actually you obviously have only a single instance with 10 connections. An instance of a zenon driver is when in Editor you create new driver, (separated EXE task on Windows) a connection when in driver configuration dialog you create new 'Connection' to a particular PLC (the driver task opens many TCP/IP channels). 
With zenon Operator license you can run only single instance of a zenon driver. In Supervisor (or Editions) you could create as many instances as PLC and then stop separately.

Yes, you are right for instances and connections.

As I understood, disconnect from some Connections (from Instance), is not possible?
Only If we use Supervisor, with more instances with single connection, we bassicaly shuld to disconnet from Instance?

yes

the alternative would be to "switch off" (status bit OFF) all affected variables: one-by-one (action in set value dialog) or by a recipe in RGM.

You mean Switch off spontaneous value from Write set value->dialog box?

Thanks a LOT !
