OMS MAXv WatchDog Timeout Counter
++
+ 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. +
++ 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; +
