Summary:

S7NT driver may crash at Citect shutdown if PLCs are offline.

Solution:

If the S7NT driver fails to bring any PLCs online, Citect may crash on shutdown. The solution is to set these in the Citect.INI file [ioserver] alwayscallstopunit=1 alwayscallstopchannel=1 or use the S7NT driver from version v2.06.02.001 . NB: Most API based drivers such as S7NT should use the above INI settings.
