This program allows the user to test Modbus communication from a standard PC to any type of Modbus compliant device using either a serial (RS232, RS422 or RS485) or Ethernet (Modbus TCP or Modbus over TCP) connection. This program consists of a user friendly interface that allows the user to test communication quickly and easily. When the program is first started the main screen appears.

The first step involves setting up communication with the attached device through either serial or Ethernet. The second step involves entering the correct device and register addresses and then selecting the command to issue to the device. The third step is where all testing takes place and includes a view of register values that were read, register values that are to be written, raw Modbus data as sent and received from the device, and finally a log.
