4.1.1 General Information
The BTV 20.4A is a PC-based machine operator terminal that also contains all
the hardware of the MTA 200 control system. Depending on the configuration,
slots are available for customer-specific extensions in the PC bus.
This chapter describes the BTV 20.4A in its version for the MTA 200
control system. The BTV 20 can also be delivered as a pure indus‐
trial PC, as a PC with integrated PLC, or as a PC with integrated
MTC200 control system. These versions are described in the gen‐
eral BTV 20 documentation DOK-MTC200-BTV20.3****-PR0x-EN-

Fig.4-1: BTV 20.4 front panel
The front panel consists of a 4 mm thick aluminum panel with beveled edges.
It is coated with a chemical resistant polyester foil with embossed keys that
covers the whole front panel. The integrated 10.4" TFT color display provides
excellent visualization of the data. A 3.5" floppy disk drive, a reset button and
a connection for an external keyboard or a mouse are located under the floppy-
disk flap. Three LEDs indicate the operating state of the BTV 20.4. A key-
operated switch locks the safety functions.
