Micrologix Master Modbus PowerFlex 4 Slave Modbus

First of all, I would like to dedicate this practice to Miguel Custodio. As we have seen before, the Micrologix can be the Master in a Modbus network, after that first test with the simulator, today we are going to carry it out but with a PowerFlex, we are going to control our drive via Modbus.

The first thing we do is configure the communication parameters, just as we did before.

The values we want to write/read to our drive will be done through MSG Messages, where each of them points to an address, depending on what we want to achieve.

An essential requirement is to know the addresses of the registers we want to access, whether to read or write; for this, I am attaching a PDF with information that cannot be overlooked. Here is an example of the Setup of the main Message.

Here is a PDF with the most relevant addresses.

An image of the messages sent and received between the Micrologix and the PowerFlex.

And to finish, a small online video of the operation. I recommend changing the video setting to 720HD.

If you liked it or found it useful, share it... :-)
