XD-ETH20

Product features

Implementation of Xingda Yikong Modbus RTU to Modbus TCP Gateway (XD-ETH20)Modbus TCPnetwork andModbus RTUThe data communication between serial buses can supportRS485Communication. namelyModbus TCPandModbus RTUSeamless internal connections between networks.

Product Features:

This product is widely used to support RS485Interface soft starter, frequency converter, intelligent high and low voltage electrical appliances, power measurement device, intelligent on-site measurement equipment, instrumentsPLCTheDCSTheFCSwait.

Simple configuration: Users do not need to understand ModbusDetails only need to refer to the manual and configure the gateway according to requirements, without the need for complex programming, and the connection function can be achieved in a short period of time.

Data function:

Data exchange: cache areaServeraddress mapping

General modules: question and answer, receive, output command polling modeContinuous output mode

Byte exchange method: no exchange2Byte exchange4Byte exchange4Byte size side swapping

ModbusTechnical Indicators:

The configurable parameters areModbusCommunication baud rate, data bits, parity check mode, stop bit, communication transmission mode, response waiting time, polling delay time, output command polling mode, pulse output time, scan ratio

ModbusCommunication baud rate:1200bit/s, 2400bit/s, 4800bit/s, 9600bit/s, 19200bit/s, 38400bit/s, 57600bit/s, 115200bit/.

Data bit:7、8、9 Position.

Parity check methods: none, odd, even

stop bit1 Position2 Position.

Response waiting time: when ModbusThe time to wait for a response from the slave station after the master station sends a command, range:

100ms~50000ms.

Polling delay time: When ModbusAfter the main station sends a command and receives a correct response or a response timeout, it sends the next oneModbusDelay time before command, range:0~2500ms.

Output command polling mode:ModbusWrite commands with four output modes: continuous output, prohibited output, variable output, and pulse output

Continuous output: and ModbusThe output method of the read command is the same, scanning and outputting according to the scanning ratio;

Prohibit output: Prohibit output ModbusWrite commands;

When there is a change in the output data, output a write command and stop outputting after receiving the correct response data;

Pulse output: Output write commands according to the pulse period.

Pulse output time: pulse time of pulse output mode

Scanning ratio

ModbusRegister starting address:ModbusThe starting address of registers, switch values, coils, etc. in the substation equipment ranges from:0~65535；

Number of registers:ModbusThe number of registers, switch values, and coils in the substation equipment;

Memory mapping starting address: The starting address of data in the module memory buffer, and the address range of data mapped in the gateway memory: Read command:0x000~0x5DB（0~1499）

Write command:0x5DC~0xBB7（1500~2999）

Writing commands can also serve as a local data exchange:0x000~0x5DB（0~1499）
