Diagnostic parameters for digital inputs/outputs
r0721 CU digital inputs terminal actual value
Display of the actual value on the digital inputs
Bit Signal name
00 DI 0 (X122.1)
01 DI 1 (X122.2)
02 DI 2 (X122.3)
03 DI 3 (X122.4)
04 DI 4 (X132.1)
05 DI 5 (X132.2)
06 DI 6 (X132.3)
07 DI 7 (X132.4)
08 DI/DO 8 (X122.7)
09 DI/DO 9 (X122.8)
10 DI/DO 10 (X122.10)
11 DI/DO 11 (X122.11)
12 DI/DO 12 (X132.7)
13 DI/DO 13 (X132.8)
14 DI/DO 14 (X132.10)
15 DI/DO 15 (X132.11)
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
08 DI/DO 8 (X122.7)
09 DI/DO 9 (X122.8)
10 DI/DO 10 (X122.10)
11 DI/DO 11 (X122.11)
12 DI/DO 12 (X132.7)
13 DI/DO 13 (X132.8)
14 DI/DO 14 (X132.10)
15 DI/DO 15 (X132.11)
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
