Echo Profile (3.1.)
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
(Page 216)].
To request a profile via SIMATIC PDM:
Open the menu
Device – Echo Profile Utilities
. [For more detail see Echo Profile Utilities via
SIMATIC PDM (Page 72)].
To request a profile via the handheld programmer:
1. In
PROGRAM
mode, navigate to
Level Meter > Diagnostics (3.) > Echo Profile (3.1.)
2. Press
RIGHT arrow
to request a profile.
[For more detail see Requesting an Echo Profile (Page 51)].
Electronics Temperature (3.2.)
Current Internal Temperature (3.2.1.)
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
.
Highest Value (3.2.2.)
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
.
Lowest Value (3.2.3.)
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
.
