8.3.5.8 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:
COMMAND OPTIONS Read/Write DESCRIPTION
LOOP HTR UID R/W Assign Heater device to Temperature
LOOP AUX UID R/W
Assign Auxiliary device to
Temperature
LOOP P R/W Set the P Value
LOOP I R/W Set the I Value
LOOP D R/W Set the D Value
LOOP PIDT OFF:ON R/W Sets automatic PID values (from
