If a DI/DO is parameterized as output (p0728.x = 1), then r0721.x = 0 is displayed.
DI: Digital input
DI/DO: Bidirectional digital input/output
r0747 CU digital outputs status
Display of the digital output status
Bit Signal name 0-signal 1-signal
08 DI/DO 8 (X122.7) Low High
09 DI/DO 9 (X122.8) Low High
10 DI/DO 10 (X122.10) Low High
11 DI/DO 11 (X122.11) Low High
12 DI/DO 12 (X132.7) Low High
13 DI/DO 13 (X132.8) Low High
14 DI/DO 14 (X132.10) Low High
15 DI/DO 15 (X132.11) Low High
Inversion via p0748 is taken into account.
It does matter whether DI/DO is set as an input or output (p0728).
DI/DO: Bidirectional digital input/output
