Applies To:
  • CitectSCADA v6.10 spk B
Summary:
Citect is running fine on the local network, but then crashes when I connect to a WAN. Over the WAN there are multiple projects also running.

Solution:
Please check that the IO device numbers are unique across the different projects. They may be separate projects, but the servers use the IO device number to find a device, which may cause a conflict.

Having the same numbers across servers which are connected appears to cause them to crash or hang.
