Features
GW-7228 J1939 to Modbus RTU Gateway is a solution that provides a communication transformation between J1939 protocol and Modbus RTU protocol. For J1939 CAN networks, the GW-7228 supports PDU1, PDU2, broadcast and destination specific type of J1939 messages. From Modbus RTU networks, From the view of Modbus RTU network, the GW-7228 is a Modbus RTU slave to replies to requests from the Modbus RTU master. We provide a software utility software for users to configure the GW-7228 parameters of CAN J1939 / Modbus RTU. The application fields can be Diesel power-train applications, In-Vehicle networks for trucks and buses or wherever you need to allow communication with CAN J1939 protocol. GW-7228 is a J1939 Communication Device that allows you to join J1939 and Modbus RTU networks.
