Siemens 6AV4010-1AA00-0AA0 Comm Processor

This communication processor handles data exchange between HMI devices and PLCs. The Siemens 6AV4010-1AA00-0AA0 belongs to the SIMATIC HMI product family. You can connect operator panels to SIMATIC S5 or S7 controllers. Its dual-port design supports simultaneous communication with multiple devices.

Physical Dimensions and Hardware Layout

The Siemens 6AV4010-1AA00-0AA0 measures 12.0 cm in overall width. Its total depth reaches 11.5 cm including connectors. This communication processor weighs approximately 0.35 kg. A metal housing provides excellent electromagnetic shielding. Three diagnostic LEDs display power, transmit, and receive activity.

Communication Ports and Protocol Support

This processor features one RS‑232 port and one RS‑485 port. The Siemens 6AV4010-1AA00-0AA0 supports the AS511 protocol for S5 controllers. It also handles the PPI protocol for S7-200 systems. You can configure baud rates from 1200 to 115200 bps. The module automatically detects the connected PLC type.

Energy Storage and Data Buffering

Internal capacitors preserve configuration data during brief power dips. The Siemens 6AV4010-1AA00-0AA0 stores up to 256 bytes of temporary data. This buffer prevents message loss during port switching events. Consequently, HMI communication remains stable and uninterrupted.

Connection Modes and PLC Compatibility

You can connect this processor to S5 CPUs via the AS511 interface. The Siemens 6AV4010-1AA00-0AA0 works with S5-95U, S5-115U, and S5-135U models. For S7 systems, use the PPI port on S7-200 CPUs. The module supports multi-drop connections on the RS‑485 port. Therefore, one processor can serve multiple HMI devices.

Configuration and Diagnostics

Configure the Siemens 6AV4010-1AA00-0AA0 using ProTool or WinCC Flexible software. Set the baud rate and protocol parameters via DIP switches. Three front panel LEDs simplify troubleshooting tasks. A flashing TX LED indicates active data transmission. A steady RX LED confirms proper PLC communication.
