Distributed Management

Post by jiji.thankappan » Thu May 16, 2019 10:17 am

Hello all,

In distributed manager Architecture, can we distributed the driver managers on different machines.
and can more than instance for the same driver (bacnet for example ) running independently on separate machines.

Yes, it is possible to start a driver manager on a remote machine.
If you have several drivers of the same type you can start every driver on it's own computer. How many drivers of the same type can connect to a WinCC OA server should be described in the WinCC OA Documentation.

Why do you want to start the drivers on own computers?

Please keep in mind that you have an additional network connection (possible cause of failure) if you are starting the driver on a remote machine.

the reason behind distributing the driver managers over many machine that we are having a largo number of I/Os, over 600K most of it are BACNET,
so because we believe it will be too much load to Run the Drivers for all this number on single machine.
in the same time we don't want to go for distributed system architecture , it will expensive and we only need to only to distribute the i/O collection

If you are starting the drivers on several machines which connect to the same server you still will have a WinCC OA server where the Event Manager has to handle data for all the drivers.

Are you sure that your server system is capable of handling data for all the drivers?
How many value changes per second do you expect as constant load in your system having 600.000 IOs?
