Migrating Citect Server to another PC

Iván

Hi everybody!

Currently we have a PC running all the server processes (IO, Trend, Report,...). We pretend to migrate Citect Server to another PC.

But I'm not sure how to bring together the old trends. After some research I found out that trends are stored in Data folder, so... is it just copy and paste this folder ??

Besides, we defined our accumulator variables to be stored in an IO Device with OFSOPC protocol, so I understand these variables are in a OPC Server in the Citect server pc. 

Thanks for your help

  • By default, trends are stored in the Data folder. Yes, you can just copy that to the new PC. You should check your trend tag definitions to see if they have a path\filename specified. It is possible to store trends in other folders. See TN5933 Trend Redundancy Backfilling for information about moving trend files.

    The OFSOPC protocol can be used to communicate with the OFS software, but it is also used for internal (memory or persisted memory) devices. Accumulators are normally stored in persisted memory devices. Check if your I/O Device definition has Memory: TRUE and Persisted: TRUE (or blank) selected. Persisted device tag values are backed up to a .CACHE (XML) file in the Data folder by default. Check the File Name field of the I/O Device to see if a custom persistence path/filename was specified. You just need to move that file to the new server to get the accumulated values.
