Configure quickly
Define the starting point and quantity for each data type through menus, then save and reload unique configurations. Run multiple instances when the test calls for it.
Mdbus for Windows
See every signal. Test every response.
A practical Windows tool for developing, monitoring and testing systems that use the MODBUS protocol—across serial connections, LANs and the internet.
4 modesMaster, Slave, Host, Monitor
32 slavesPoll from one Host instance
RTU / TCPSerial and network support
Core capabilities
One bench tool, from first packet to full system test.
Mdbus connects MODBUS devices to the Windows environment for configuration, data acquisition, simulation and communications diagnostics.
Observe the wire
View transmitted and received MODBUS messages, isolate traffic by slave number, CRC error or function, and log received messages to a file.
Simulate both ends
Operate as a Master or Slave over MODBUS RTU or ASCII. Exercise data acquisition, control functions and upset scenarios before commissioning.
Connect over IP
Communicate through the internet or LAN with devices and applications supporting Modbus RTU/TCP, in either Master or Slave mode.
Move data into Excel
Use a direct DDE interface with Excel and other compatible programs. Dump values from multiple slaves into a spreadsheet with one DDE poke.
Add OPC when needed
Choose the Standard package or the edition with an OPC Server option, depending on how the test environment needs to exchange data.
Operating modes
Put Mdbus where the system needs it.
Select a mode to see how the same toolkit can support development, commissioning and troubleshooting.
Mode 01 / Master
Poll, control and validate a slave device.
Designate a slave, watch communications status and statistics, acquire data with function codes one through four, and exercise control with five and six.
Live communications statusSee whether the link is responding as expected.
TX / RX message viewInspect traffic during communications testing.
A practical workflow
Configure once. Reuse the setup. Inspect the details.
Move from connection to evidence
A focused flow keeps repetitive test work efficient while preserving the diagnostics needed to find intermittent problems.
