The ST100A Series Manufacturer Specific or Device Specific commands start at command 137. Use the device specific commands to
setup and configure the ST100A Series instrument via HART. The ST100A Series device specific commands are grouped in functional
categories as summarized in Table 14 below.
Table 14 – ST100A Series HART Device Specific Command Groupings
Group No. Description Command Numbers
Group 1 Commands to set up and configure the instrument. 137, 138, 139, 140, 145, 146,
148, 149, 150, 159
Group 2 Commands to set up 4–20 mA output channels including the OUTZ, and
OUTF parameters.
