Anybus X-gateway J1939 - Modbus RTU

Intelligent J1939 to Modbus RTU slave gateway

The Anybus X-gateway J1939 Gateway provides connectivity between a Modbus RTU-network and a J1939 CAN network. The X-gateway appears as a Modbus RTU Slave device allowing a Modbus RTU Master to read or write data from the J1939 network.

Easy configuration - No programming needed

Togeteher with the X-gateway a free Windows based configuration tool (BWConfig) is provided. This PC based software allows the user to map J1939 parameter (PGN) data into a range of memory addressable through the Anybus X-gateway Modbus RTU interface.

Configuration of the X-gateway is simple using BWConfig and consists of setting up an I/O table containing selected J1939 PGNs and the rate that each will be read or written from the J1939 network. BWConfig will then automatically map the I/O table to a range of addresses accessible from the Anybus X-gateway Modbus RTU interface.
The configuration is downloaded from the PC to the Anybus X-gateway via an RS232 connection and is saved in FLASH memory.

Features and benefits
