This function detects when the output set value exceeds the range for which conversion is possible.
• If the output set value exceeds the upper limit of the conversion range, the converted value is fixed at
the upper limit. At this time, the Over Range Status turns ON and a Unit Over Range for Channel
event (event code: 64F00000 to 64F70000 hex) occurs.
• If the output set value falls below the lower limit of the conversion range, the converted value is fixed
at the lower limit. At this time, the Under Range Status turns ON and a Unit Under Range for Chan-
nel
event (event code: 64F80000 to 64FF0000 hex) occurs.
• When the output set value returns to the conversion range, the fixing is cancelled and the value
becomes the normal converted value. When the cause of the error is removed and the error is reset,
the Over Range/Under Range Status turns OFF.
• Refer to
on page A-39 for details on status and
on page 8-7 for details on events.
