Parameters
3. Diagnostics
3.1. Echo Profile
Allows you to request the current echo profile either locally via the handheld
programmer, or remotely via SIMATIC PDM, or AMS Device Manager. (For more
detail see Echo Processing on page 126.)
To request a profile via SIMATIC PDM open the menu Device – Echo Profile Utilities.
(For more detail see
Echo Profile Utilities
on page 49.)
To request a profile via the handheld programmer:
a) In PROGRAM mode, navigate to LEVEL METER > DIAGNOSTICS (3) > ECHO
PROFILE (3.1)
b) Press RIGHT arrow to request a profile.
(For more detail see
Requesting an Echo Profile
on page 38.)
3.2. Electronics Temperature
3.2.1. Current Internal Temperature
Read only. Displays (in degrees C) the current temperature on the circuit board
recorded by the internal electronics.
For access via SIMATIC PDM open the menu View – Process Variables and
check the field Electronics Temperature.
3.2.2. Highest value
Read only. Displays (in degrees C) the maximum temperature recorded by the
internal electronics. The high and low values are maintained over a power
cycle.
Via SIMATIC PDM navigate to Maintenance and Diagnostics > Electronics
Temperature.
3.2.3. Lowest value
Read only. Displays (in degrees C) the minimum temperature recorded by the
internal electronics. The high and low values are maintained over a power
cycle.
Via SIMATIC PDM navigate to Maintenance and Diagnostics > Electronics
Temperature.
