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.
