Parameters
The following parameters are set on the Configure Points screen.
Default Output Condition Flags: The default output conditions are a set of checkboxes to establish
device-based parameters. These default output conditions apply to all outputs on this device. After
making changes to the flags, click the Send Flags button to submit the changes to the device.
• Auto-Recover - Selecting the Auto-Recover option forces the Gateway to attempt to re-
establish communications with out-of-sync nodes after a polling error condition is indicated.
The Gateway polls the failing device and must successfully communicate with the failing
node Re-Link Count times before the error condition is erased. This parameter is only used
on the Gateway. Without the auto-recover feature selected, the user must manually reset
error conditions or the host system must reset the error condition.
Gateway Link Failure - The Gateway detected a communication problem with a Node. All
•
linked outputs of the failing device are set to the default states.
Host Link Failure - A Modbus timeout forces all device outputs to the default states. This
•
parameter applies to every device that sets this flag.
• Node Link Failure - A Node detected an RF link problem and set its own outputs to the
default states.
• Out of Sync - When an out-of-sync condition is detected, all Node outputs are set to the
default value. This parameter applies only to the Nodes.
• Power Up - All device outputs are set to the default value on initial power-up.
Delta: The delta parameter defines the change required between sample points of an analog input
before a change of state has occurred. To turn off this option, set the Delta value to 0.
Hysteresis and Threshold: The threshold defines a trigger point or reporting threshold (ON point)
for an analog input. Enter a 0 to turn off the threshold, otherwise use a specific value, e.g. 15 mA
for a 0-20 mA analog input. Threshold and hysteresis work together to establish the ON and OFF
points of an analog input.
The hysteresis value establishes how much below the active threshold (ON point) an analog input is
required to be before the input is considered
off. When set to 0, hysteresis is turned off. A
typical hysteresis value is 10% to 20% of the
unit's range. In the example given above, the
input is considered on at 15 mA. To consider
the input off at 13 mA, set the hysteresis to 2
mA. The input will be considered off when the
value is 2 mA less than the threshold.
I/O Enable: Select the checkbox to enable
the individual I/O point. If the checkbox is not
selected, that I/O point is disabled, regardless
of what other parameters may be defined.
For efficient power usage, do not enable I/O points that are not used.
I/O Name: The I/O name field is an optional text field used to assign names to the individual I/O
points for easy reference. This name may appear in many other screens relating to the I/O point.
I/O Number: Click on the I/O # hyperlink on the far left of the screen to access an additional
screen for I/O point configuration. The expanded screen contains more I/O point parameters than is
displayed on the primary page.
I/O Selection: Select the I/O type from the drop-down list. The drop-down list includes all options
available for the entire DX80 line. Not all I/O types included in the drop-down list are applicable for
any given device. Refer to the device data sheet to determine which options are available for each
device.
Max Bad Count: The max bad count refers to a user-established maximum count of consecutive
failed polling attempts before the Gateway considers the RF link to have failed.
