This may be a simple question.
I understand the concept and application of analog modules (i.e. Compactlogix) for transducers, and outputs for VFD speed reference and such but my question is regarding the use of Ethernet/IP for the analog. For example we have a couple Ethernet based SICK encoders that do not report to a HSC module--there isn't one on the rack and Drives are speed referenced thru Ethernet as well....does this indicate the analog and signals are traveling thru the Ethernet and these modules are not necessary as the code is being handled in the controller without the dedicated module interface of a HSC or Analog input/output modules?
