4.3.2 Configuration Error Word
The Configuration Error Word contains Client and server configuration error
indications, in a bit-mapped format. Specific bits in the module's Configuration
Error Word are turned on (set to 1) to indicate various configuration errors. The
Configuration Error Word appears in three separate MNET.STATUS controller
tags. Since there is only one Configuration Error Word for the whole module,
each of these tags contains exactly the same data, even though the tag name
might imply otherwise. Multiple copies of the same module error data have been
included in these different controller tag locations for your convenience when
troubleshooting.
Bits set to 1 in the Configuration Error Word indicate the following errors.

Combinations of errors will result in more than one bit being set in the error word.
Correct any invalid data in the configuration for proper module operation. A value
of zero (0) in this word indicates all bits are clear, which means that all module
configuration parameters contain valid values. However, this does not mean that
the configuration is valid for the user application. Make sure each parameter is
set correctly for the intended application.
