Summary:

I have added an I/O Device to my project but when I start-up the Citect runtime I get the following error message:

Failed to Load Database '_IODev' (FILE NOT FOUND)

... where IODev is the name of the I/O Device that I've just added.

Solution:

Some drivers (e.g. Bailey) use address mapping which means that any I/O Devices using these drivers will require variable tags to be configured. To eliminate this start-up error message, make sure that you have added at least 1 Variable Tag for that particular I/O Device before starting up the Citect runtime.
Keywords:
