HMS AB7000-C Anybus PROFIBUS Gateway

AB7000-C is an Anybus Communicator protocol converter from HMS Networks, acting as a bridge between RS232/422/485 serial devices and PROFIBUS-DP V0 industrial bus. It converts Modbus RTU, ASCII, custom serial protocols into standard PROFIBUS data, presenting serial device data as simple I/O blocks to Siemens, ABB and Rockwell PROFIBUS master PLCs without modifying field equipment firmware.

This DIN rail-mounted gateway has been discontinued by the manufacturer and serves as critical maintenance spare for legacy factory and process automation systems. It features multi-status LED indicators for network diagnostic, supports offline configuration via PC software, and delivers galvanic isolation between serial and PROFIBUS ports to suppress industrial electromagnetic interference.

Core Functions

Realize bidirectional protocol conversion between serial field instruments and PROFIBUS-DP PLC master stations, realizing unified bus management of serial equipment.
Built-in flexible serial frame editor supports custom serial protocol parsing, compatible with old sensors, inverters and weighing instruments without hardware upgrades.
Modbus RTU quick configuration wizard simplifies parameter setup, only 6 steps to complete data mapping without complex PLC programming work.
Galvanic isolation design separates serial side and PROFIBUS bus to eliminate ground loop noise and protect PLC bus circuits from surge damage.
Offline configuration storage allows one-time parameter setup and batch replication for multiple production line equipment, improving engineering deployment efficiency.
Real-time bus fault diagnosis via front LED lights quickly locates PROFIBUS disconnection, serial cable break and communication timeout failures during on-site maintenance.
