Timeout determines every packet by determining the time interval betweenĬharacters. Specified for the Modbus gateway under serial setting ( Figure 5). These devices need to be match with each other. Their serial port settings such as baud rate, data bits and stop bits of Maximum of 247 devices can be connected in parallel to the Modbus gateway and Only change it if necessary, otherwise leave it in the default settings.įigure 4 - Modbus RTU/TCP gateway network settings You can communicate with the gateway using these settings.

Under network settings ( Figure 4), you can customize the Modbus gateway Setting including network, serial and modbus settings.įigure 3 - Modbus RTU/TCP gateway overview In this surface, you can configure all the gateway After the page have loaded, you will see the overview ( Figure 3) IP address of the Modbus gateway: 192.168.10.254 to the browser URLīar. Table 2 - Network settings of the PC and the Modbus gatewayĪfter successful configuration, open your web browser and type the Voltage requirements, they must be operated from a separated power supply.įinally, you need an Ethernet cable to connect the Modbus gateway to the PC.įigure 2 - Modbus RTU/TCP gateway wiring diagram Specifications of Modbus gateway How to wire these devices to the gateway. Same serial port parameters including baud rate, data bits, stop bits and parity.įurthermore, each device must be have an unique slave ID.

You can connect maximum of 247 slaves (such as relay board, temperature sensorĮtc.) in parallel to the Modbus RTU/TCP gateway. See how to wire the slaves to it, how to set up, and there is an example how use.įigure 1 - Modbus RTU/TCP gateway Connect the Modbus RTU/TCP gateway to PC Modbus Ethernet devices with Modbus serial devices. This is a multifunctional serial Modbus gateway, which integrates Devices / Masters | USB to RS485 converters
