Modbus Master Serial King: Modbus Field Communication Test Assistant

Modbus Master 7.0.21

04H -- Read Input Register, Byte Operation
Modbus RTU, Modbus ASCIICan be based onTCP/IPOrUDP/IPMethod of communication mode. Suitable for running on any platformWindowsUnder the platform. Green software, No need for any runtime libraries.

Feature Overview:

1. Select Ethernet as the connection methodTCP, EthernetUDP, serial portRTU, serial portASCII, Modbus RTU(TCPTong
   News)Modbus RTU(UDPCommunication), Modbus ASCII(TCPCommunication), Modbus ASCII(UDPCommunication)
2. If it is a serial portRTU, ASCII: Set serial port client serial port and parameters, Click to open, Different registers can be selected for read and write operations.
   if it isTCP, UDP, RTU(TCP|UDP), ASCII(TCP|UDP):
   Set up the clientIPAnd ports (Default502) , Click the link, After successful connection, Different registers can be selected for read and write operations.
3. This software serves asModbus main site(i.e.Mdobus client)
   Use, can read coil register(Output Coil), Discrete input register(Input Relay), holding register(HoldingRegister), input register(Input Register), Extended register(Extended Register)the data, At the same time, it can be written into the coil register(Output Coil), Maintain the sender(HoldingRegister), Extended register(Extended Register)data; Data can be displayed in a formatted format, Bring convenience to testing work.
