A transition on bit 2 of Pump Control will toggle between local and remote control of the pump. For example,
if the pump is in local mode, then a 1 to 0 transition will put the pump into PROFIBUS remote control mode.
Only in this mode can any change in the cyclic output data in uence the pump and be re ected in the cyclic
input data.
Set Dispense Mode can be one of the following:
Continuous
Time Dispense
Volume Dispense
Set Tube Size and Set Flow Units are integer numbers, beginning with 1. e numbers correspond to the pump’s
local menu list in the front panel display interface. For example:
tube size “13” from the local menu list corresponds to the value “1” for the Tube Size output value
ow units “gal/hr” from the local menu list corresponds to the value “9” for the Flow Units output value
Set Flow Rate is a decimal oating-point number. Its value must be between the Minimum Flow Rate and Maxi-
mum Flow Rate values from the input data.
Set Dispense Volume is the amount of volume that will be dispensed in Volume Dispense Mode.
Set Dispense On Seconds is the amount of time the pump will dispense in Time Dispense Mode.
Set Dispense O Seconds is used for both Time and Volume dispense modes. It sets the amount of time the
pump will pause between dispenses.
