In addition to the alphanumeric display, operator guidance is also assisted with key LEDs.
The best possible adaptability for suiting customer wishes has been integrated into the COMPACT MMI PANELWARE 4B1270.00-490 in the form of key legends which can be changed or replaced at any time through the front of the unit. The same method as the key legends has also been used for customized company logos or product names. The 4B1270.00-490 MMI is also sealed to IP54 standards. In spite of the advantages of the PANELWARE philosophy there are still other applications which can be solved with a simpler terminal.
