Bộ chuyển đổi cổng J1939 sang Modbus TCP Server RTU Slave ICP DAS GW-7238D-G CR

The GW-7238D is a gateway that provides conversion between J1939 and Modbus TCP/RTU protocol. For J1939 network, the GW-7238D supports PDU1, PDU2, broadcast and destination specific type of J1939 messages. For Modbus TCP/RTU network, the GW-7238D is a Modbus TCP server / RTU slave to reply the request from Modbus TCP client / RTU master. Utility software is provided for users to configure J1939 and Modbus TCP/RTU setting in the GW-7238D. The application fields can be diesel power-train applications, In-Vehicle networks for trucks and buses, etc.
The following figure shows the application architecture for the GW-7238D

• Diesel power-train applications
• In-Vehicle networks for trucks and buses
• Truck-Trailer connections
• Fleet management systems
• On Board Diagnostics
• Vehicle Automation\
