Underrange (index 0x6020:01 / 0x6030:01), Overrange (index 0x6020:02 / 0x6030:02)

Underrange and overrange of the measuring range

• Underrange:
  The bits in index 0x6020:01 / 0x6030:01 (underrange bit) and index 0x6020:07 / 0x6030:07 (error bit) are set.
• Indicates that the output value is below -256 (approx. 0.8 % of end value; -32767 for bipolar terminals).
• The output value is limited to 0 (-32768).
• For bipolar terminals underrange is also set if the ADC outputs the lower limit value.
• Overrange:
  The bits in index 0x6020:02 / 0x6030:02 (overrange bit) and index 0x6020:07 / 0x6030:07 (error bit) are set.
• Indicates that the output value is above 32768.
• The output value is limited to 32768.
• Overrange is also set if the ADC outputs the upper limit value.

For overrange or underrange the red error LED is switched on.
