ICP DAS releases a new application for ISaGRAF PACs – tGW-700 Gateway Application. It can solve the problem about poor communication efficiency of the long distant RS-485 network.

User sometimes has to choose lower speed transmission (lower baud rate) for long distance communication via Modbus RTU/ASCII over RS-485/RS-422. This often leads into a new problem of inefficient communication. The tGW-700 series gateway of ICP DAS can solve this problem. Using the tGW-700 series gateways can change the RS-485 to the high speed Ethernet and eliminate the cable length limitation of the RS-485 network to solve the problem about poor communication efficiency.

The tGW-700 series is a Modbus TCP to Modbus/RTU or Modbus/ASCII gateway that enables a Modbus/TCP host (i.e. the WP-5147) to communicate with serial Modbus RTU/ASCII devices through an Ethernet network, and eliminates the cable length limitation of legacy serial communication devices.

This application uses the ISaGRAF WinCE PAC to control/monitor a system. When the system becomes a long distant RS-485 network, user can change RS-485 to high speed Ethernet communication by add one tGW-700 series gateway to enhance the communication efficiency, and still use the RS-485 to connect the local modules to keep the low cost feature. Welcome to try our new tGW-700 Gateway Application to solve the poor communication problem!
