The Siemens 6AV2123-2JB03-0AX0 is a SIMATIC HMI KTP900 Basic operator panel with a 9-inch TFT touchscreen, 65,536 colors, 800x480 resolution, and 8 function keys, connected over a single PROFINET interface. It runs on 24 V DC and is rated IP65 at the front, IP20 at the rear.
One industrial Ethernet interface and no RS-485 or RS-232 port means this panel talks to the controller over PROFINET only -- a KTP900 Basic variant with a serial port is the pick when the target PLC doesn't support PROFINET. The 10 MB user memory and 800x480 resolution fit machine-level status, alarm, and recipe screens (50 recipes, 100 records each); a heavier multi-screen application needs a Comfort Panel instead of the Basic line. Marine approvals across GL, ABS, BV, DNV, LRS, and NK make this panel usable in shipboard control panels without sourcing a separate marine-rated model.
Machine-level operator interface for status and alarm display and recipe entry, PROFINET-connected HMI on SIMATIC S7-1200/S7-1500 stations, and marine or offshore control panels.
