OverviewThe Anybus Communicator is a protocol converter that connects serial field devices to PROFINET-IRT control systems. It maps serial protocols to PROFINET-IRT I/O, enabling integration of RS-232/RS-422/RS-485 equipment into industrial Ethernet environments with secure and deterministic data exchange.
Key product descriptionThe Anybus Communicator AB7078-B operates as a Serial Master (Modbus RTU client/master) and translates common serial protocols (Modbus RTU, DF1 and proprietary request/response or produce/consume transactions) to PROFINET-IRT (Slave). A pre-defined Modbus RTU setup with a 6-step wizard simplifies commissioning. The device is designed for IP20 protection and DIN-rail mounting to reduce wiring effort and allow installation near connected equipment. Save/Load configuration enables reuse across installations. Models with Dual Port switched Ethernet support daisy chaining.
Features and benefits- Protocol conversion without changes to existing serial devices or PLC software; pre-defined Modbus RTU support with 6-step wizard.
- Fast integration of Modbus RTU and other standard serial protocols (DF1) as processed I/O data for PLCs.
- Support for custom request/response and produce/consume transactions; trigger-initiated operations.
- Compact IP20 housing for DIN-rail (EN 50022) mounting to decrease cabling distances.
- Dual Port Ethernet options for daisy chaining, reducing need for external switches.
- Save & Load configuration for reuse and faster deployment.
- Long product lifecycle and manufacturer-provided network updates.
- Certifications: CE, UL, WEEE; hazardous-location UL information available.
