Free tool for searching Modbus devices on a serial network or an Ethernet network.

**Marcom Modbus Scan** is a very useful tool for scanning Modbus RTU (RS485 / RS422) networks or Ethernet networks to find Modbus slaves.

The software is very simple to use: just select the serial or Ethernet communication parameters and start the scan.
The software checks for the presence of the slave by requesting address 1 of the holding register area. If the device responds with an error or with the register value, it is listed among the present devices.

It is possible to select different speeds for the serial port, the TCP port, and the IP address for Ethernet communication, as well as the range of Modbus addresses to test.

The software requires:**Windows 7/8/10/11 (32 bit and 64 bit) + .Net Framework 4.6.2**
