According to the Beckhoff „measurement error” a reference value can be calculated as specified in section “General information on measuring accuracy/measurement uncertainty”.

That result is for the measurement range ±10V by the above given data and an environment temperature of TEnvironment,max = 55°C to ±321 ppmFSV (or 0.032%FSV).

See also measurement error/measurement deviation/measurement uncertainty, output uncertainty under Continuative documentation for I/O components with analog in and outputs.

Representation ±10 V measurement range

Note: In Extended Range Mode the Underrange/Overrange display in the PDO status has the character of an information/warning when the nominal measuring range is exceeded, i.e. no Error is displayed in the PDO status and LED. If the technical measuring range is also exceeded, Error = TRUE is also displayed. The detection limit for Underrange/Overrange Error can be set in the CoE.

In Legacy Range mode, an Underrange/Overrange event also leads to an Error in the PDO status.
