5.3. Tool
– Device Communication
The following items need to be addressed with the customer to define the
new advanced diagnostic protocol:
Tool to provide status (e.g. isolation valve status upstream and
downstream)
Some operations require knowing the status of the isolation valves on both
sides of the device. The tool shall provide this information by writing to the
isolation valve status attribute whenever the status changes.
Note: At this time, this is not implemented on the customer tool software.
Request from the device to the tool to modify the tool status (e.g.
Operating the isolation valves at the request of the MFC)
Some operations require a specific state of the isolation valves on both sides
of the device. The tool shall read the isolation valve request attribute on a
schedule TBD and satisfy the request of the MFC.
Note: At this time, this is not implemented on the customer tool software.
