Table 4-8. Command and Query Reference (cont)

ALARMS?	Active Alarms Query
	Returns alarm status for the indicated channel(s). The value returned
	represents data from the most recent scan. The most recent scan is the
	scan in progress or, if scanning is not in progress, the last completed
	scan.
	ALARMS? <channel>
		<channel> = (0 .. 20)
	If the channel specification field is left blank, values for all defined
	channels are returned (values for channels defined as OFF are not
	included.) An Execution Error results if a request is made for a channel
	defined as OFF, the channel specified is invalid, no scan measurements
	have been made, or review values have been cleared.
	Data is returned as comma-separated integer values, indicating which
	limits were in alarm when last scanned. The returned values are
	interpreted as follows:
	0 neither limit is in alarm and/or alarm(s) not defined
	1 Limit "1" in alarm
	2 Limit "2" in alarm
	3 Limit "1" and Limit "2" in alarm
	If measurements are not active, the last known value is returned. The
	value 0 is returned for measured channels that do not have alarms
	defined.
	For alarm status of all defined channels (no channel specification made),
	undefined (OFF) channels are not included. For each defined channel,
	an integer value (0, 1, 2, or 3) is returned. Commas separate integers for
	different channels, and no blank spaces are included. For example, if
	channel 1 has no alarm, channel 12 has Limit "2" in alarm, channel 13
	has Limit "1" and Limit "2" in alarm, and channel 14 has Limit "1" in
	alarm, the return is "0,2,3,1".
ALARM_ASSOC	Associate Alarm Output
	For the indicated channel and alarm limit, associate the given digital
	output line.
	ALARM_ASSOC <channel>,<limit_num>,<DO_line>
	<channel>	=	(4 .. 20)
	<limit_num> = 1 2
	<DO_line>	=	(0 .. 7)

Any other values or use of an invalid channel cause an Execution Error to be generated. If an association already exists for the specified channel and limit, executing this command revises the association. When switching alarm associations, the output being left (switched away from) is set to a high (non-alarm) state. To set multiple channels to a single DO_line, issue this command for each association to be made.
