Hello,
I've read on some posts that to add a VFD to a PLC program you first have to download the AOI from the Rockwell website. My question is, why is that really necessary to do when you can simply a VFD module on the I/O configuration in the PLC program and control the VFD. What's the need and value to download the AOI or is it only needed to do for older PLC like Micrologix ?
Thanks
