Say 10 seconds worth and when a trigger like either a m= essage or say an error flag occurs the logging to the circular buffer goes = for 5 seconds and then is stopped and saved. =20 Essentially the system shows random faults and they'd like to know what hap= pened for 5 seconds on either side of the event. =20 =20 The even can be: a contact closure like a button pressed by an operator; a= specific message, Bus error as signaled by an error flag. =20 Does a tool like that exist? =20 Thanks John Dammeyer =20 "ELS!
