DES
H30
Communications Link Function (Mode selection)
y98 (Bus Link Function, Mode selection)
Using the RS-485 communications link (standard/option) or fieldbus (option) allows you to issue frequency commands and
run commands from a computer or PLC at a remote location, as well as monitor the inverter running information and the
function code data.
H30 and y98 specify the sources of those commands--"inverter itself" or "computers or PLCs via the RS-485
communications link or fieldbus." H30 is for the RS-485 communications link; y98 for the fieldbus.
