While upgrading xA from 5.0 to 5.1 we are facing a problem of disconnection of 5.0 connectivity server
We are upgrading xA from 5.0 to 5.1 on-line and we have faced following problem,
- we have created separate client/server netwrok for V5.1 with one Connectivity, one Aspect and one domain server.
- We have sucessfully upload in V5.1.
- we have also simulate the value in V5.0 and same was getting updated in V5.1.
Problem : while taking controller on-line, we have to give 'warm' download from V5.1 and same time OPC DA of V5.0 is disconnected.
This seems clear to me, once you are downloading to the Controller, all your Clients should be on the 5.1 System already. The Controller Configuration will be different to the Values stored in the 5.0 System now. I didn't check but i am quite sure this is also what is described in the Upgrade Manual as well...?
I'm sorry that that this answer will not help you!
Only one firmware + application version can be in the controller at the same time, 5.0 or 5.1 (unless you are performing a true OLU*).
The 5.1 OPC server can only connect when 5.1 is downloaded and vice versa for the 5.0 OPC server.
By having some servers/clients at 5.1 and some on 5.0 you can perform a "bumpless" upgrade.
*) OLU = Online upgrade (requires redundant controller and HMI servers).
