SIEMENS 6AV3505-1FB01, also named OP5 operator panel, is a compact text-based human-machine interface for small PLC automation system. It is designed to display process messages, set parameters and trigger control commands, supporting local machine operation for old automation equipment renovation.

This panel delivers reliable operation control for machine control tasks. The operation control supports text message display, setpoint modification and alarm message indication. The operation control comes with function keys for manual operation and machine status checking. Stable operation control completes on-site operation and status monitoring for standalone machinery.

The built-in communication circuit achieves steady data interaction. The data interaction communicates with S7-200 / S7-300 PLC via RS485 interface. The data interaction transfers real-time machine status and user operation commands. Accurate data interaction ensures synchronous data exchange between HMI and PLC controller.

Panel embedded structure brings convenient cabinet fitting. Cabinet fitting can be embedded into control cabinet front panel. Cabinet fitting connects power supply and PLC communication cable via rear terminal block. Flexible cabinet fitting is widely used for legacy OP5 system spare replacement.

6AV3505-1FB01 supports alarm buffer storage, password protection and multi-language text display function, equipped with RS485 communication port and 24VDC power terminals. It has LED status indicators for power and communication diagnosis. Widely applied in packaging machines, conveyor systems and small processing equipment.
