On its 4.5-inch screen, the Siemens 6AV6641-0CA01-0AX1 displays operator screens at a resolution of 160 × 64 pixels. The SIMATIC HMI OP 77B uses a monochrome yellow-green backlit STN display. The active screen area measures 102.38 × 40.94 mm; contrast and backlighting are coordinated with the graphical display. The panel is operated by a membrane keyboard instead of a touchscreen. It has 23 system keys and eight configurable softkeys, four of them with LED. Two labelling strips are assigned to keys F1 to F4 and K1 to K4. For communication, the OP 77B has a switchable RS-422/RS-485 interface for MPI and PROFIBUS DP. RS 232 and a USB port for peripherals and project transfer are also available. Internal working memory is 1 MByte. A slot optionally accepts a Siemens MMC as external storage. Engineering uses WinCC flexible 2004 Compact or a newer designated version. The rated supply is 24 V DC, with a permissible range of 18 to 30 V DC. Typical current consumption is approximately 200 mA, while the stated maximum continuous current is around 300 mA. The front of the enclosure meets IP65 and the rear is specified as IP20. For control-panel installation, the front measures 150 × 186 mm and the total depth is 38.5 mm. The required cut-out is 134 × 170 mm. Without packaging, the OP 77B weighs approximately 500 g.
