How to Use the Win-GRAF PAC to Connect the tGW-700 to Expand Modbus RTU Master Ports

PublishTime：2022-01-15

If using the Modbus RTU (RS-232/485/422) device to transmit data in a long-distance application area, the user will normally choose a lower baud rate for better signal quality.But, using this way will cause low transmission efficiencies. In order to improve this problem, ICP DAS releases the tGW-700 series products (tiny Modbus TCP to RTU/ASCII gateway) for converting Ethernet/RS-485 signals so that the user can reduce the RS-485cable lengths and solve the issue with inefficient communications.
This paper will provide a demo program (demo_tgw725.zip) to describe how the Win-GRAF PAC communicates with LC-103 modules via the tGW-700 gateway (as the figure below).
