Owners 2-105
Conversely, any number of adapters can simultaneously issue Stop
Commands. Therefore, Stop Ownership is not exclusive.
Example:
The operator presses the Stop button on the Local HIM to stop the drive.
When the operator attempts to restart the drive by pressing the HIM Start
button, the drive does not restart. The operator needs to determine why the
drive will not restart.
The operator first views the Start owner to be certain that the Start button on
the HIM is issuing a command.
Start Owner
When the local Start button is pressed, the display indicates that the
command is coming from the HIM.
Start Owner
The [Start Owner] indicates that there is not any maintained Start
commands causing the drive to run.
Stop Owner
The operator then checks the Stop Owner. Notice that bit 0 is a value of “1,”
indicating that the Stop device wired to the Digital Input terminal block is
open, issuing a Stop command to the drive.
Until this device is reclosed, a permanent Start Inhibit condition exists and
the drive will not restart.

Start Inhibits and Start Permissives.
