The operator interfaces are intelligent visualization systems for automation applications. They can be installed in control cabinets or panels, for example. Users operate the device via the membrane keyboard integrated into the front plate and via the LCD display with touch screen. Communication with control and automation systems runs via interfaces (RS-232, RS-422/485, Ethernet) connected in the "e"-area at the back of the devices. Various peripheral devices, such as barcode scanners, card readers, USB sticks and WLAN / Bluetooth modules can be connected via USB interfaces or optional fitted modules. With a wealth of functions, these operator interfaces provide optimum visualization. Their active communication concept in combination with integrated functionality reduce the automation system workload. The ET-3x6-Tx and ET-3x6-Fx operator interfaces are compatible with their predecessors (ET-8A and ET-12), both in terms of software and functionality.
