RIO Outputs fields

Table 51. RIO Digital Outputs.
Name
Point Select up to eight digital outputs, DO1 to DO8, from
Type the following types:
• DISCRETE1 through DISCRETE8
• FLOAT1_OPEN through FLOAT8_OPEN
• FLOAT1_CLOSE through FLOAT8_CLOSE
• MODULATE1 through MODULATE8
The following additional parameters are also
available for configuration:
• Speed for Floating DOs
• PWM settings for Modulated DOs
For floating outputs, a corresponding float close
should be available for a float open and vice versa.
If not, the wizard gives an error message while you
try to save the configuration.
RIO Deltas
Use Table 52 to configure the RIO Deltas.
Purpose
Delta is an adjustable threshold that allows the user to
determine, on a per-sensor basis, what change in value is
required before the sensor is updated. All Excel 10 controllers
have a guaranteed periodic update time of 55 seconds, which
requires that all sensors report any change every update
period. The delta for each sensor is used to reduce LonWorks
Bus traffic by reducing the amount of updates on a sensor that
are constantly or quickly changing. View or modify Deltas
(change thresholds) for sensors.
Mode
Configuration can be performed with the wizard Off-line or
On-line.
Procedure
1. Click the Deltas_pane button on the left pane to open
the RIO's Delta Configuration page.
2. Enter information into available fields.
3. Click Commit to save the settings or Reset to revert to
the last saved settings.

Definition
4. If sensors are being used for display only, then they can
have a larger value for the delta and rely on the
guaranteed periodic update to update the sensor every
55 seconds regardless on the amount of change.
5. If the sensor is bound to another Excel 10 controller,
configure a smaller delta so that the control algorithm
does not see large changes in value.
6. The default value of 0 sends an update every 2
seconds.
7. Click Back to display the RIO's Input Configuration
page.
