Commissioning the Digital Level Controller for use with the HART Tri‐Loop
To prepare the digital level controller for use with a 333 HART Tri‐Loop, you must configure the digital level controller
to burst mode, and select the dynamic variables to burst. In burst mode, the digital level controller provides digital
information to the HART Tri‐Loop HART‐to‐Analog Signal Converter. The HART Tri‐Loop converts the digital
information to a 4‐20 mA analog signal. The HART Tri‐Loop divides the signal into separate 4‐20 mA loops for the
primary (PV), secondary (SV), and tertiary (TV) variables. Depending upon the burst option selected, the digital level
controller will burst the variables as shown in table 2‐1.
The DLC3010 status words are available in the HART Burst messages. However, the Tri‐Loop cannot be configured to
monitor them directly.
To commission a DLC3010 digital level controller for use with a HART Tri‐Loop, perform the following procedure.
