Subject: Aerotech Ensemble home search problem
From: Ron Sluiter <[email protected]>

I recently discovered a problem with performing a home search from the EPICS motor record when using an Aerotech Ensemble motor controller.  The problem is that the EPICS Ensemble driver uses Aerotech's ASCII communication protocol and that protocol blocks all communication on ASCII communication ports during a home search.  Consequently, once a home search is started from EPICS, it is unable to stop it.

Aerotech is aware of the problem and have plans to fix this, but a release date has not been set yet.

I have made a motor record minor bug fix release (6.5.2) available here with the home search function commented out of the Ensemble driver.  I advise Ensemble users to upgrade to this version.  Users that need to perform a home search should do it from Aerotech's IDE software, which can abort a home search.
