The Rockwell 2711-T9A8 is a panel for industry belonging to the PanelView Standard Terminals 900 line. A vital condition to ensure the correct functioning of the terminal is ventilation. The operator should provide sufficient space within the enclosure and take into account other systems in the heat analysis. The environment temperature close to the module has to be between 32 and -131 degrees Fahrenheit when the device is operational and has to stay in the range from -13 to 158 degrees Fahrenheit when the operator terminal is in storage conditions. An access to must be guaranteed to make sure to manage to deal with maintenance, troubleshooting and wiring tasks. The terminal must not be subjected tremors above 1 g at 2000 hertz. The user can simply connect other systems (e.g: a PLC) to the terminal operator exploiting its DH+ interface. The energy consumption of this model should be around 50 watt at its nominal temperature. The Human-Machine-Interface grants the use of a memory card to be able to download or backup HMI programs. The panel provides the user a 640 x 400 pixels monochromatic display. The operator can use the panel via its touch-screen UI. The top impact that the HMI can withstand is 15 g during running settings and 30 g when the panel is shut down.

The Allen-Bradley 2711-T9A8 standard operator terminal allows its operators to establish connections between the different industrial applications and machines, as well as the humans controlling it. There is a nine (9) inch monochrome display on this standard operator terminal. DH+ and RS-232 printer communication ports can also be used for configuring this standard operator terminal. Furthermore, it also comes with the 2711-NC13 communication cable that serves the purpose of programming. In order to input data and control this HMI (human machine interface), users need to use the touchscreen. For power, this operator terminal requires one hundred and twenty (120) volts alternating current (AC).

One thousand and eight (1008) kilobytes is the internal memory rating on this module, as this device has two hundred and forty (240) kilobytes (kb) of application memory and seven hundred and sixty-eight (768) kilobytes (kb) of bitmap and text storage. If damaged, the backlight on this operator terminal can be replaced. Eight (8) pounds is the shipping weight of this module. The measured shipping dimension of this operator terminal is approximately sixteen (16) inches by fourteen (14) inches by eight (8) inches. This Allen-Bradley standard operator terminal is an F series terminal. This operator terminal supports data highway plus terminals. Thanks to this terminal, it is capable of establishing point-to-point communication.

For this, users need to use a single controller. On the other hand, using multiple controllers over the Allen-Bradley DH+ network, users can establish network communication. Minimization of ladder logic is possible thanks to direct access to the controller files.
