10.3.5.7 Addressing a pressure control loop
To address a control loop, you must specify the pressure sensor that is associated with the
control loop:
DEV:<UID>:PRES:
where <UID> is a unique identifier that is allocated to each board, based on its SPI location.
The configuration settings for a control loop are DEV:<UID>:PRES: followed by:
