You can receive the MODBUS protocol or SDK.
The MODBUS protocol allows simple communication within a variety of network architectures. Every device (PLC, HMI, control panel, driver, motion control, input/output device) can use the MODBUS protocol to initiate remote operations.
Modbus RTU Data frame structure
The instructions in the RTU protocol are composed of five parts: function code (one byte), starting address (two bytes), address code (one byte), data (N bytes), check code (two bytes), in which the data is composed of data length (two bytes, indicating the number of registers, assuming the content is M) and data body (M multiplied by two bytes).
Take 01 06 00 00 00 1F C8 02 for example
01 Address 01
06 Write Register
00 00 Register 0 corresponds to variable 0
00 1F The value 31 is displayed
C8 02 Modbus CRC verification code
Modbus TCP data frame structure
Modbus TCP adds MBAP packet header to Modbus RTU. Since TCP is a service based on a reliable connection, there is no CRC check in Modbus TCP. All Modbus TCPADU sends and receives TCP transmission control protocols. The Modbus TCP/IP server usually uses port 502 as the port for receiving packets.
Take 00 01 00 00 00 06 01 06 00 00 00 00 00 1F for example
01 Address 01
06 Write Register
00 00 Register 0 corresponds to variable 0
00 1F The value 31 is displayed
Modbus TCP The network protocol is not verified.
The modbus.ini file also supports text display by modifying the parameter configuration. The following is a description of the displayed text configuration parameters.
