���� = �������� + ���� + ������������ ���� ���� ���� ����
The scaling formula is:
���� is the user scaled data in the input table in engineering units.
Where:
���� is the slope: (�������� ���� ℎ���������������� ���� ���������������� ���� ���� − ���������������������������� ���� ���������������� ���� ����)/(�������� ���� ℎ�������� ���� ������������ −
�������������������� ���� ������������ )
���� is the ADC signal data at the terminal block converted to corresponding data
���� is the offset: ���������������������������� ���� ���������������� ���� ���� − (���� ∗ �������������������� ���� ������������)
format.
Once the module receives the configuration, the Range Scaling feature is always
active.

3.6.3 Process Alarms

Process alarms allow you to specify alarm limits for the input signal, and to have
the module report when those signal limits have been exceeded. The feature is
active if enabled in the channel(s) configuration.
To set up, input the desired alarm values (Enable Process Alarms, Process Alarm
Latch, Process Alarm High Value, Process Alarm Low Value) for each channel
into the configuration table, as described in Configuration Assembly. Report a
configuration error if any alarm value in the configuration table has been set
incorrectly.
Set the Process Alarm High status bit in the channel status struct when the
channel input value is greater than the Process Alarm High Value in the
