With TnD Version 8 you will also find the app notes & user manual installed on your local drive. Look in C:Program FilesPhoenix ContactThinkNDoDocs


This app note includes a downloadable example which consists of some subcharts which implement the Modbus master protocol. These Thinklets will run on either an NT/2000/XP-based system or a WinPLC utilizing the serial port. We recommend using the project 'as-is' and getting it to communicate with your device FIRST (before adding the subcharts to your project). It includes an HMI and serial port IO configuration and you should be able to read/write to the registers on the RMU.
