APPLICATION and System Requirements

Use the CAS Modbus Scanner to find the correct port settings and the correct slave address. The tool automates the process of trying all the combinations and reports the results.

The tool works for RS232 and RS485 by allowing you to search for a single device or multiple slaves. To connect to a RS485 network from your laptop you simply need a USB-to-485 converter.

  • Windows 2000, XP, Vista, Windows 7 (32bit or 64bit), Windows 8 (32bit or 64bit), or Windows 10(32bit or 64bit)
  • 10mb of free space
  • Modbus RTU requires an RS485 port. You will need to purchase a USB to RS485 converter (ACON U-01)
