Desired Operator Mode Dispense Flow 
Rate

Desired Operator Mode Dispense Flow Rate is a byte 
used to request a new operator mode dispense flow rate 
to the EFR. If the value supplied is within the operable 
range and the EFR is running in operator mode, the 
value will be accepted by the EFR and reflected back to 
the Active Operator Mode Dispense Flow Rate of the 
Automation Inputs.
