Anybus X-gateway J1939 - Modbus TCP

Intelligent J1939 to Modbus TCP slave gateway

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

Fast copying of I/O Data

Data from J1939 messages are mapped to I/O table locations, making them accessible to the Ethernet network. The X-gateway acts as a Modbus TCP server, allowing J1939 data to be addressed as Modbus registers by a Modbus TCP client device.

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 TCP 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 TCP interface.
