ID of the request Modbus frame to the set value in Fixed ID Value textbox.ДЇigure 6 - Modbus RTU/TCP gateway modbus settingДЇor more information about how to set up the gateway, please download theД®xample Latch channel 1 of a relay board using Modbus TCP If it changed to fixed, the gateway change the the slave

The ID mapping in auto ID mode, the gateway does not make any change Response timeout time when accessing slave device. The default port number of the standard Modbus TCP protocol is 502, but you canДЄlso modify it according to your own application. The connections sets the maximum connection to the Modbus gateway. Network is the Modbus TCP master device, and the serial port is the Modbus RTU

In this case (TCP Master - RTU Slaver), the In modbus operating settings shown on Figure 6, the operation modeДetermines the way of working.

The interface determines the type of the serial port.ДЇigure 5 - Modbus RTU/TCP gateway serial settings Timeout determines every packet by determining the time interval betweenД¬haracters. 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.ДЇigure 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.ДЇigure 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 URLД«ar. Table 2 - Network settings of the PC and the Modbus gatewayДЄfter successful configuration, open your web browser and type the Voltage requirements, they must be operated from a separated power supply.ДЇinally, you need an Ethernet cable to connect the Modbus gateway to the PC.ДЇigure 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.ДЇurthermore, each device must be have an unique slave ID. You can connect maximum of 247 slaves (such as relay board, temperature sensorД®tc.) 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.ДЇigure 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
