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


HMS provides the X-gateway with a free Windows based configuration tool (BWConfig). 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.

J1939 interface

  • SAE J1939 network interface with a unique network address in accordance to the J1939-81 specification
  • Max 496 bytes of I/O Input data and 492 bytes of I/O Output Data
  • Up to 120 PGN's monitored by Input data points
  • Up to 100 PGN's  transmitted by Output data points  
  • Supports J1939 network baud rates of 250K and 500K
  • Transmission and reception of all types of fixed-length J1939 messages, including PDU1, PDU2, broadcast and destination specific
  • Monitoring of DM1 (active diagnostics) and DM2 (previously active diagnostics) messages
  • Complete network address management including address claim, protection, and yield on higher priority conflict
  • Network address can be self-configurable over a range of addresses
  • J1939 Transport Protocol for transmission and reception of large messages (9 - 1785 bytes). Both connection based (RTS/CTS) and broadcast (BAM) are supported
  • Configurable CAN bus-off reset option will reset the network interface and attempt to return to online when a CAN bus-off condition is detected
  • 1x 5-pole 5.08 mm Phoenix pluggable screw connector for J1939
