Configuration
1. Open File Explorer and change target folder to the Modbus Service installation folder.
2. Open and edit the file Mobus_Handler.ini
2.1 Give a Name for the platform.
2.2 Set the Protocol.
For the modbus TCP devices:
Protocol=Modbus_TCP
ClientIP=(IP address of Modbus TCP devices)
ClientPort=(Port of Modbus TCP devices)
Example:
For the modbus RTU devices:
Protocol=Modbus_RTU
SlavePort=(The serial port's device node of the gateway which connect to Modbus RTU devices)
Baud=(The baud rate of the serial port)
Parity=(The parity of the serial port)
DataBits=(The data bits of the serial port)
StopBits=(The stop bits of the serial port)
Example:
2.3 Set the number of modbus devices and device detail information file.
Example:
2.4 Set the content of device detail information.
Example:
EdgeSense Linux Docker version
How to config Modbus Service and Restart Service
