Data Type Double-Point Indication (Dp, Input)/Double Command (Dc, Output) - Siemens SIPROTEC PROFINET IO Manual

2.3.3

Data Type Double-Point Indication (DP, Input)/Double Command (DC, Output)

Number of byte values:
Range of values:
0 = "not applicable"/
disturbed state for DP and
idle state for DC
1 = OFF
2 = ON
3 = disturbed state for DP,
not allowed for DC
NOTE
Depending on the data type selected in DIGSI, the values 0 and 3 for double-point indications have the
following meaning:
−
Type DP:
−
Type DP_I:
"not applicable":

NOTE
The data type double command requires the associated command feedback to be parameterized as double-
point indication.
A double command with a single-point indication as feedback or without feedback acquisition is controlled in
the same way as a single command via PROFINET IO. This means that the processing of a double command
via PROFINET IO depends on the type of the associated feedback.
