The following procedure outlines setting up Modbus RTU communications between the AKI HMI and a third party device. With a Modbus TCP/IP connection between the PxMM and the same AKI HMI this configuration allows data to be transferred between…
It is important when working with Modbus to establish the addressing conventions in the beginning before programming your Modbus Master ( i.e. PLC, HMI, etc. ) and understand how the master’s addressing convention correlates to the AKD drive’s Modbus…
The Service Port on all AKD drive models supports Modbus TCP, EXCEPT the ProfiNet model (AKD-P-NxPN). While the AKD-P-NxPN can communicate Telnet and ProfiNet at the same time, Modbus TCP support was NOT added to this…
This application note provides a basic overview of the Telnet and Modbus TCP communication protocols. Telnet is demonstrated using Hyperterminal.
Where to find resources and information on both Telenet and Modbus TCP are given.
Modbus TCP is made easy in the AKD Basic drive with the use of "User Defined" Modbus registers. These are the 5000 series Modbus address numbers. The registers are defined in the Basic program and mapped to variables. You can then…
