CT-5801: Terminal module

CT-5801: Terminal module
Terminal modules are used to stabilize the internal bus communication.

Each C series I/O protocol adapter must be equipped with 1pc of terminal module CT-5801 no matter how many sub-modules are connected.

The dustproof terminal could cover the internal bus and field power supply hardware of the last IO module.

And terminal modules have no process data and configuration parameters.

* Take no module channel and replace CT-5800.
