3.3.2 Selecting Logged Variables
By default, the device variables that will be logged are the PV (primary device variable), PV%, Out
(mA), and SV (secondary device variable). If the device supports command 33 of the HART specifi-
cation, you alternatively have the option to log different variables.
After you have started HPCLogger and polled for devices (see section 3.3.1) follow these steps to
select non-default variables:
1.
Select a device from the Live List.
2.
Select the desired 4 variables to log from the 4 drop down menus on the Specific Monitor
screen (Figure 11).
3.
Select “Done”.
NOTE:
Only devices which support command 33 of the
HART specification will support custom selection of
logging variables. Devices which do not support this
command will only log the default variables as de-
scribed above and will not have access to the Spe-
cific Monitor screen.
