Analog Input, 16 Bit Thermocouple, 7 Channels
Module Features
Channel Active
Each channel can be configured as either active or inactive. If a channel is
inactive, the filtering, scaling, calibration, and alarm checks are omitted for that
channel, and a value of 0 is returned for the channel. The reference parameter
for the analog input data returns the byte length and is independent of the
number of active channels.
Low Alarm Limit and High Alarm Limit
Each input channel can have a low alarm limit and a high alarm limit. If an input
reaches one of its limits, the module reports the actual value and reports an
alarm fault in the I/O Fault Table. Alarms do not stop the process or change the
value of the input. Alarm limits can be set anywhere over the dynamic range of
the signal. The range for each is –32,768 to +32,767. The high alarm limit must
be greater than the low alarm limit. If alarm reporting is not wanted, alarm limits
can be set beyond the dynamic range of the signal so they will never be
activated.

thermocouple types.
