Why does the message "Try to load another SCommCom.dll" appear?

FAQ #100358

If an other tool is using a different SCommCom.dll (Webconnect, Visi+, OPC...) than PG5, an error message will appear when opening PG5



The following message window will appear:


There are several tools using the SBC Communication Driver (SCommDrv.exe, SCommdll.dll). If they are not using the same version of the SComm.dll, it is not possible to run them at the same time.

Tools using Scomm.dll:

  • Webconnect
  • Visi+
  • Merz OPC
  • Various SCADA systems
  • All tools from the PG5 controls suite
