*1 If the Expansion Setting Parameters are not used, the Process Value HH (High High Limit) Alarm and Process
Value LL (Low Low Limit) Alarm will be 0.
*2 This value will be 0 if neither the Expansion Setting Parameters nor the Expansion Operation Data are used.
*3 This value will be 1 if an error occurs in the A/D conversion. If the error is not cleared after the Unit restarts or
the Controller is reset, including when the power is turned OFF and back ON, check whether there is a source
of noise nearby. For details, refer to 3-1-12 Error Processing.
