Modbus Master for the Pocket PC

Ver 1.06 Now Only £12.49

The Modbus Master program allows you to communicate with one or more Modbus devices connected to the serial port or ethernet network port of your Pocket PC. With a suitable RS232 to RS422/485 converter, you can configure the program to communicate with up to 10 devices at the same time if you are using a multidrop connection. If you are using the network connection, you can communicate with a single modbus device or if you are connecting through an ethernet bridge to your modbus devices, you can communicate with up to 10 devices at the same time.

You can also configure up to 10 data blocks to show the data polled from each device. The individual data blocks are shown in a grid format on screen and can display up to 64 words of information at a time. You can easily scroll backwards and forwards through the memory map of the Modbus device to show more data as required.

The data can be shown in a variety of formats including :

• Hex
• Decimal
• Binary
• Unsigned Short
• Signed Short
• Unsigned Long
• Signed Long
• Float

Double words formats can also be shown in High/Low or Low/High word format.

If the data block allows writes, you can simply click on a cell in the grid and modify the data value shown. This new value will then be written down to the Modbus device.

A protocol trace screen is also available to show the raw data being sent and received from the Modbus devices. This trace can also be sent to a file if required.

You can also capture the poll data to a CSV file for later analysis using a program such as Excel.

You can download a free trial copy of the program by clicking here.
