The Operating Mode Command bits (output array) can be used alone or in parallel with the
controller’s switchpad and discrete isolated inputs to change the controller’s operating mode. To
change the operating mode, the fieldbus master should set the desired Operating Mode
Command bit high. Once received, the controller will store the new operating mode in memory,
then return an updated Operating Mode Status byte to the fieldbus master (input array). The
fieldbus master should verify that the correct Operating Mode Status bit has changed, then
complete the command by setting all Operating Mode Command bits low. Setting the bits low
allows the controller to accept operating mode inputs from the switchpad and discrete isolated
inputs.
