Omfins error 0x40 occurs when an IO module is removed from the rack. By default, when this occurs, tags associated with the device will not be able to be read because the error has a severity level of GENERIC_GENERAL_ERROR. Some people may wish to still be able to read tags from the device under this situation. 

CIT has confirmed this to be a problem in the OMFINS driver. This problem has been fixed in version of the driver. A new Citect.ini OMFINS parameter has been added. This parameter is called IgnoreNonFatalError. By default it is set to 0, indicating error 0x40 will be treated as an error with severity GENERIC_GENERAL_ERROR. If it is required to still be able to read tags when the error occurs, set [OMFINS] IgnoreNonFatalError to 1.
