So I'm kind of a noob when it comes to PLCs and am curious about the communication between controllers and drives.
I've heard the term cyclic data or cyclic communications thrown around, but I'm not sure if I know exactly what it means. Does cyclic data simply refer to data that is updated/recorded/read during every scan of the PLC? Also, is that how a drive, VFD for example, communicates with a controller when monitoring parameter values of the drive?
I'm sure every controller and drive configuration is different, but maybe someone could explain this?
