Industrial gateway Anybus AB7077-B

communicationRS-422Modbus RTU

Overview
The Anybus Communicator converts serial protocols to CC-Link IE Field, allowing RS-232/RS-422/RS-485 devices to be integrated into CC-Link IE Field control systems. It provides secure, high-speed protocol conversion and is designed for straightforward configuration and industrial interoperability.

Features and benefits

• No hardware or software changes required: pre-defined support for Modbus RTU and a 6-step Modbus RTU wizard to avoid scripting and manual serial frame building.
• Hassle-free connection to Modbus RTU: wizard-based setup and pre-defined configurations.
• Wide compatibility: converts standard serial protocols such as Modbus RTU and DF1, as well as custom request/response or produce/consume proprietary protocols.
• Slim IP20 DIN-rail design: installs close to field devices to reduce cabling.
• 3-year warranty.
• Improved PLC performance: presents serial data as easy-to-process I/O for PLCs via intelligent protocol conversion.
• Save & Load configurations for reuse across installations.
• Daisy-chaining: Dual-port switched Ethernet versions enable daisy chaining without external switches.
• Lifecycle management: HMS provides network updates and product maintenance throughout the lifecycle.

Product description
The Communicator AB7077-B functions as a protocol gateway translating serial master traffic into CC-Link IE Field slave data. It supports reliable, deterministic transfers and is intended for industrial network interoperability and protocol conversion between serial devices and CC-Link IE Field controllers.
