Analog modules
6.11 Analog input module SM 331, AI 6 x TC isolated (6ES7331-7PE10-0AB0)
Calibration consists of several different steps, during which the individual calibration values
are determined.
● If a fault occurs during calibration or if new parameters are assigned to the module, the
calibration of the relevant channel is canceled and the most recently active calibration
values for the channel become effective once more. All of the calibration values recorded
up to this point are lost. The module can now handle the current process values once
again.
● Calibration can be canceled at any time once it has been started. Following cancelation,
the previously active calibration values take effect again and the calibration values
recorded up to this point are lost. The module can now handle the current process values
once again.
