The SMARTONE also allows the user to define the Message Interval while
the Inputs are in an Undesired State, either Opened or Closed.
Usage Example: A company has remote containers at job sites and
would like to know if a door is ajar. If a door is left ajar
the company would like a notification every 2 hours. Based on
this requirement, the SMARTONE would be connected to an open
door sensor with the Undesired Input State Message enabled and
set as Opened with a Message Interval of 2 hours.
Note: The SMARTONE uses a 5 minute "hysteresis" window to prevent sending
false alarms. This means that only one status change message can be sent
during any 5 minute time window. Any subsequent status changes will be
detected but not reported. Multiple status changes during any 5 minute window
will result in the transmission of incorrect trigger bits. Refer to page 52
for "Input Status Changed Message".
The SMARTONE has the ability to send an Accumulate/Count Message at a
regular configurable interval and/or based on configurable multiples of
accumulated hours and/or number of counted events or hours of vibration.
Usage Example 1: A construction company needs weekly engine run
times for their heavy equipment to manage their maintenance
scheduling. Based on this requirement, the company would
schedule a weekly Accumulate/Count Message.
Usage Example 2: A construction company wants to insure that no
equipment is ever operated beyond 400 hours without maintenance.
Based on this requirement, the company would schedule an
Accumulate/Count Message for every 400 hours of use.
The SMARTONE has the ability to send both Status Change and Undesired State
messages based on vibration.
Serial Commands
The SMARTONE uses the I/O port for unit configuration as well as interface to
remote passive and smart sensors. Two commands are provided in the unit
interface to support smart sensors. External sensors or instruments that can
format and communicate to the SMARTONE can send user data through the
SMARTONE by using these two commands.
The SMARTONE connects to smart sensors via the SMARTONE Serial Cable.
Spot offers 2 accessory cables for the SMARTONE, the USB Configuration
Cable and the Serial Cable. See Appendix E: Accessories.
