ModScan32 is powerful tool, which can emulates Modbus RTU and Modbus ASCII. It can use serial port (COM), parallel port (LPT), Ethernet (TCP/IP) and Infra Red..
It is very useful to test Modbus RTU embedded in our drives.
Using serial port, ModScan32 can access Control / Status Word and all group of parameters.
