DBF file handling Question - data flow Clients - Servers to a corporate file server with Plant Scada 2023R2 Update 9

Version = Plant Scada 2023R2 Update 9

my project has a database i am finding has become "intermittently" unstable possibly after recent upgrade from Citect SCADA 2018 to 2023R2 or some security updates pushed out by IT Dept or Microsoft.

what i am noticing is slow performance in read/writes to this database file. Note the code is 7 + years and has not been modified so has proven very reliable to now.

i am trying to understand the data flow and where the issue is. 

when operators make a change to the process, a cicode file writes this change or reads from the  *.dbf file that resides on the "Corporate file Server" in a folder.

the folder and file is mapped as a network drive on the SCADA server. in devices "file name" field  \\Servername\database_folder\MyDB.dbf (example only) is the path to the location on the corporate File server

for the above configuration i would like some explanation of the data flow for this.

QUESTION when an operator makes the change from either SCADA Client A, B or C is the data written to the corporate server directly or via the SCADA server?

  • SCADA Client > Corporate Server

                                    OR

  • SCADA Client > SCADA Server > Corporate Server

 i am unsure of what the corrective action was as i tried many things (restart SCADA, reboot all SCADA machines, recompile, pack etc) one or more of these rectified the issue.
