Function restriction in the DFRFG function block in case of a negative input signal (eliminated in V7.1 or V7.3)

Eliminated from:
9300 vector 0.37…90 kW SW7.3 and
9300 vector 110…400 kW SW7.1

Eliminated function restriction:
In contrast to the positive input signals at the DFRFG1-IN function block the output profile generated has not been created correctly in case of negative input signals. The added input signal should generate a corresponding output profile as soon as a LOW level is assigned to the DFRFG1-QSP signal. This was not the case with negative input signals since in the DFRFG1 function block a wrong interpretation and handling of the internal states existed.

The comparison request between the input signals at DFRFG1-IN has been changed. Now, the comparison is made with 'DFRFG1-IN > 0' and no longer with 'DFRFG1-IN ≥ 0'.
