When using either the AlarmAck or AlarmClear functions to acknowledge or clear a disabled alarm, it is found that the functions do not acknowledge or clear the alarm. However they do not return an error code under these circumstances. 

CIT has confirmed this to be a problem that has been fixed in Citect version 5.20 Service Pack A. The fix has been made so that the functions return error code 366 under these circumstances. This error code indicates the function was not successful because the alarm was disabled.
