Sensitivity blocks
All I/O registers have a configurable sensitivity value that determines
how much the register needs to change before a change-of-state”
(COS) message is sent. All registers except the following have a
default sensitivity value of 1:
•
The 12 analog inputs have a sensitivity of 1000 counts,
or approximately 3% (1000 counts from a total range of
32768 = 3.05%).
•
The 24 floating point values have a default sensitivity of 0.5 units.
•
Inputs 38001–38004 will be 0.5 mA, inputs 38005–38012 will be
in volts, and inputs 38013–38016 will be in hertz.
A sensitivity value is needed for analog inputs in order to prevent
the module from sending every single-bit change of an analog value,
and subsequently saturating the radio channel with unwanted COS
messages. If a lower sensitivity is required, you can adjust the
sensitivity block. However, take care not reduce the sensitivity to
the point where radio messages are so frequent (due to a sensitivity
change) that it saturates the radio network. There is a fine line
between adjusting system parameters to receive up-to-date data
and overloading the radio communications. A total of 50 sensitivity
blocks can be configured for different registers or different values.
To change sensitivity blocks for a module, click
Sensitivity Blocks
in
the project tree (see
Figure 51
). The screen lists existing sensitivity
blocks for this module. To add a new sensitivity block, click
Add
. To
edit an existing sensitivity block, select it in list on the right, and click
Edit
. This displays the IO Edit screen (see
Figure 52
) where you can
change settings. To delete a sensitivity block, select it in the list and
click
Delete
.
