2.6.7. Table 1-8
If your vessel shape is more complex than any of the preconfigured shapes, you
can define the shape as a series of segments. A value is assigned to each level
breakpoint and a corresponding value is assigned to each volume breakpoint.
Level values are defined in Units (2.1.1.). Volume values are defined in Volume
Units (2.6.2.)..
Level Values
Volume Values
Enter up to 32 level breakpoints, where the corresponding volume is known.
The values corresponding to 0% and 100% levels must be entered, and
breakpoints can be ordered from top to bottom, or the reverse.
Breakpoints are grouped into four tables: Table 1-8, Table 9-16, Table 17-24, and
Table 25-32.
Entering breakpoints via SIMATIC PDM:
• See
Communications manual
Entering breakpoints via the local push buttons:
a) The default unit for level values is m: to change it navigate to Setup (2.) >
Sensor (2.1.) > Units (2.1.1.), and select the desired unit.
b) Navigate to Setup (2.) > Volume (2.6.) > Table 1-8 (2.6.7.), and enter the
value.
c) Go to the appropriate table for the particular breakpoint you wish to adjust:
for example, go to Table 1-8 for breakpoint 1.
d) Under Table 1-8, go to Level 1 (2.6.7.1.) to enter the level value for the
breakpoint 1.
e) Under Table 1-8, go to Volume 1 (2.6.7.2.) to enter the volume value for the
breakpoint 1.
f) Repeat steps c) to e), until values have been entered for all required
breakpoints.
