MGate 5118 gateway 1-port CAN-J1939 to Modbus / PROFINET / EtherNet/IP conversion

MGate 5118 industrial protocol gateways support the SAE J1939 protocol, which is based on the Controller Area Network (CAN) bus. SAE J1939 is used to implement communication and diagnostics between vehicle components, diesel engine generators, and compression engines, and is suitable for the heavy-duty truck industry and backup power systems. It is now common to use an engine control unit (ECU) to control these types of devices, and an increasing number of applications use PLCs for process automation to monitor the status of J1939 devices connected behind the ECU.

MGate 5118 gateways support the conversion of J1939 data to Modbus RTU / ASCII / TCP, EtherNet/IP, or PROFINET protocols to support most PLC applications. Devices that support the J1939 protocol can be monitored and controlled by PLCs and SCADA systems using Modbus RTU / ASCII / TCP, EtherNet/IP, and PROFINET protocols. With the MGate 5118, you can use the same gateway in a variety of PLC environments.

## J1939 Command without Typing

The J1939 protocol is designed to retrieve a wide range of data from CAN-J1939 devices. To eliminate the need to manually enter all J1939 commands into the gateway, MGate 5118 gateways can automatically detect output commands used by the CAN device.

With just one click in the Web console, all output commands from the CAN device will be automatically detected by the gateway. The commands will be displayed in the Web console's command list and, if necessary, can be further modified by the user. MGate 5118 gateways significantly simplify the connection between PLCs and CAN devices for users.

## A Variety of Maintenance Functions

MGate 5118 gateways support a Web console for easy configuration and maintenance, and the integrated traffic monitoring function monitors J1939 protocol traffic, allowing users to monitor the status of connected CAN devices, including error counts, packet counts, and bus offline status. The traffic monitoring function can also be used for troubleshooting CAN devices. The diagnostic tool helps users check CAN device settings and indicates CAN device availability by reading the J1939 network address. Furthermore, MGate 5118 gateways have a built-in Live List function for when two or more J1939 devices are connected to the same CAN bus. This function shows the PGN and address of packets transmitted by each device, giving users the ability to measure CAN bus loading.

To detect loose cables, MGate 5118 gateways support status monitoring and fault protection functions. The status monitoring function alerts a PLC when the cable between the gateway and the CAN device is loose. In addition, the fault protection function performs user-defined actions when the cable between the gateway and the PLC is loose.
