J1939 to Modbus Interface
The BridgeWay J1939 to Modbus Interface provides connectivity between a Modbus RTU (RS485 serial) network and a J1939 (CAN) network. The AB7606 operates as a Modbus RTU Slave device, allowing a Modbus RTU Master to read and write J1939 PGN data. Pyramid Solutions provides a free downloadable Windows-based configuration tool (BWConfig) for the AB7606. This PC-based software enables mapping of J1939 parameter (PGN) data into the AB7606 I/O table memory, which is accessible from a Modbus RTU Master as Modbus registers.
Configuration of the AB7606 is easy with BWConfig. It consists of setting up an I/O table containing the J1939 PGNs you wish to read or write, and the rate at which each will be read or written from/to the J1939 network. BWConfig maps the I/O table to a range of Modbus registers accessible from the AB7606 Modbus RTU interface. The configuration is downloaded from BWConfig to the AB7606 via an RS232 connection and is saved in Flash memory. You can also upload an existing configuration from the AB7606 for comparison or to update the configuration.
Use Case Examples
- A low-cost interface used on oil and gas equipment, marine vessels, locomotives, pumping stations, generators, engine test cells and other mobile and stationary equipment. Use to access engine parameters from a Programmable Logic Controller (PLC), HMI or PC and send data onto the J1939 network for control and management.
- An on-vehicle gateway used to interface a J1939 network to an onboard industrial automation based control and monitoring system or HMI
