News CNCnetPDM About us Support  




We released an updated version of our CNCnetPDM IIoT Adapter for Programmable Logic Controllers (PLC) from different manufacturers that adds new features and enhances compatibility with MS Windows 11 and Server 2022 Operating Systems (up to version 23H2).

MBUS.DLL (11/19/2023)

Upgrade instructions


We released a device driver for CNCnetPDM that enables simultaneous monitoring of PLCs from different manufacturers by a single solution.

mbus.DLL (7/16/2021)

Fully adjustable device driver that reads the status of bits (coils), digital or analog inputs and/or register data from remote PLCs and outputs it to MTConnect, OPC UA and/or various SQL databases. Allows remote control of these devices via MTConnect compatible programs or our Open Source Client.


We released ModbusGui, a graphical application that allows reading and writing of data from/to Programmable Logic Controllers (PLC). Can also be used with a cost free PLC software simulator.

ModbusGui.exe (7/16/2021)

Reads status (0/1) of single or multiple bits (coils), physical digital/analog inputs and data of holding registers from PLCs and electronic devices with Ethernet connection and Modbus protocol support. Sets status and register values at remote devices.
