Smoothing
You can also configure the module to smooth the thermocouple analog input signal over a
configured number of cycles, thus presenting an averaged value to the program logic. You
have four choices for the smoothing algorithm:
● None
● Weak
● Medium
● Strong
Source reference temperature
You configure a source reference temperature for each TC analog input module channel,
choosing one of the following options:
● Set by parameter
● Internal reference
Alarm configuration
You select whether to enable or disable the following alarms for the selected channel of the
selected TC analog input module:
● Wire break
● Upper limit exceeded
● Lower limit exceeded
● User power (Configured in the system block "Module Parameters" node; see the figure
below.)
