Plug-in module self-test

No user self-test exists for the plug-in modules. The plug-in modules perform
their own self-test when power is applied. Additionally, the mainframe checks
two-way communication with all plug-in modules at power on.
Each plug-in module also performs error checking at regular intervals during
operation and any errors detected are reported via the status system to the main
controller.
