Siemens 6AV3515-1MA22-1AA0 HMI Touch Panel Display

Siemens 6AV3515-1MA22-1AA0 is an OP15/C2 operator panel from the SIMATIC HMI family, designed for compact industrial human–machine interface tasks paired with SIMATIC S7 controllers. It features a four-line text display that can be configured as 4 lines of 20 characters each (20 CPL) or as an eight-line display with a total of 40 characters, enabling flexible labeling of process data and control prompts. The panel includes eight softkeys for quick on-screen actions and provides robust serial connectivity: two RS-232 (TTY/V.24) ports plus one MPI/PP I/L2-DP interface for integration with Siemens networks and fieldbus configurations. With 256 KB of user memory, it can store UI pages, scripts, and runtime data used by embedded HMI applications. This OP15/C2 unit is commonly deployed on machines and lines where compact operator input and real-time visualization are needed, delivering direct local control and status feedback while fitting into standard Siemens automation architectures.
