<h4>
Modifications to Existing Features</h4>
</div>
<div style="text-align: left">
<p><b>Aerotech Ensemble</b></p>
<p>
<ul>
<li>
With previous releases the Aerotech Ensemble asyn motor driver would crash the
IOC at boot-up if the Ensemble was not powered up and able to communicate.
</li>
<li>
The EOT limit switch status was not available except via an Ensemble fault
condition. With this release the status of the EOT limit switches are always
available.
</li>
</ul>
</p>
<p><b>OMS MAXv WatchDog Timeout Counter</b></p>
<p>
<p>
For OMS MAXv firmware ver:1.33 and above, the EPICS driver reads the MAXv's
Watchdog Timeout Counter at bootup, and with every motor status update. If the
Counter is nonzero, an error message is sent to both the errlog task and the
console. Since a watchdog timer trip indicates that the MAXv has rebooted and
no longer has valid motor positions, the controller is disabled and is no longer
available to EPICS until after the VME crate has been power cycled. Other MAXv
boards in the system are unaffected by this scenario.
</p>
<p>
To better communicate this problem to the user, several medm displays have been
changed. Small displays (motorx_tiny.adl, motorx.adl) will show a yellow border
around their position readback values. Larger displays (motorx_more.adl,
motorx_all.adl) will display the message "Controller Error" in yellow. The
following error message at the console and/or in the errlog is definitive;
