The HP E1313/E1413 can test readings to see if they fall within test limits.
You can program upper and lower test limits for each channel you wish to
test. You can enable limits testing against upper and lower, upper limits
only, or lower limits only.
You can query the results of limits testing several ways:
Checking Results with the CALCulate Subsystem
Composite Returns a single value. A value of one indicates that one or
more of the module's tested channels has exceeds its limits.
Channels Returns an array of 64 values. Each value corresponds to
one of the module's 64 channels. A value of one
indicates that the channel has exceeded its limits.
Individual Returns a single value for a specific channel. A value of
one indicates that the channel has exceeded its test limits.
Channel
There are two versions of each of the query types explained above:
Cumulative Cumulative limit results are accumulated from the time
the module is
limits since
the event is recorded.
Current Current limit results indicate the status of limits tested
during the last completed scan list.
Checking Results with the Status System
Polling Poll by accessing bit 11 of the Operation Status Event
Register. When bit 11 is set to one, one or more limits
were exceeded.
Interrupt If bit 11 of the Operation Status Enable Register is set,
the Operation Summary bit will be sent to the Status Byte
Register. An out-of-limits condition can then be reported
by interrupt.
