Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual
Rev Version 1.2.2
Figure 42 I/O Edit (Digital Inputs)
The following parameters can be configured for 915U-2 digital inputs.
Name
Enter a name for the digital input or leave the default name. The name can be up to
30 characters, including spaces.
Debounce Time (sec)
Debounce is the period of time that an input must remain stable before the module
determines that a change of state has occurred. If a digital input changes from on
to off and from off to on in less than the debounce time, the module will ignore both
changes. The default debounce time is 0.5 seconds.
Digital Outputs
To configure digital outputs, click
Digital Outputs
under
IO
in the project tree. Select a digital output from the list on
the right and click
Edit
. This displays the IO Edit screen (Figure 43) where you can change settings.
Figure 43 IO Edit (Digital Output)
The following parameters can be configured for 915U-2 digital outputs.
Name
Enter a name for the digital output or leave the default name. The name can be up
to 30 characters, including spaces.
Fail-safe Time (sec)
Sets the time the output needs to count down before activating the fail-safe state.
Receiving an update or a COS message will reset the fail-safe timer to its starting
value. If the fail-safe timer goes down to zero, the output will be set to the fail-safe
state (on or off).
It is recommend the fail-safe time be configured for a little more than twice the
update time of the input that is mapped to it. That way, the output will reset if it fails
to receive two update messages.
Fail-safe State
Sets the state that the output will assume after the fail-safe time has elapsed. When
the fail-safe state is enabled (on), the LED flashes briefly off, and the digital output
turns on. When the fail-safe state is disabled (off), the LED flashing briefly on, and
the digital output turns off.
