Description:
Those parameters configure if the analog output signal will be in current or voltage with direct or reverse
reference. Besides setting those parameters, it is also necessary to position the DIP switches. Refer to the
installation, configuration and operation guide of the used plug-in module.
Table 12.5: Characteristic configuration and equations of the AOx on page 12-9 below summarizes the
configuration and equation of the analog outputs, where the relationship between the analog output function
and the full scale is defined by P0251, as per
Table 12.3: Full scale of analog outputs on page 12-8 .
