I/O Status in Diagnostics

When More I/O Info is clicked, it brings up the Controller I/O Status dialog:

In most cases I/O system errors are caused by a module mismatch (i.e. The wrong module is installed in the wrong slot or the module is missing). This dialog shows the status of each individual module, that is the Module expected to be installed by Cscape and the Module which is physically installed in the controller.
