Bidirectional digital inputs/outputs

Overview
The bidirectional inputs/outputs of terminals X122 and X132 on the CU (DO1) can be used by a
drive object as well as by a higher-level controller (resource sharing). The assignment to a
terminal is defined by means of BICO interconnections which are either connected to a controller
via the DO1 telegram p0922 = 39x or to a drive object.
You can change the interconnection of the bidirectional digital inputs/outputs on the input/
output component.
• You can assign bidirectional digital inputs/outputs in the function. This means that you have
the option of parameterizing an input or an output.
• Digital inputs are used for the acquisition of digital signals. For example, drive enable signals
can be controlled externally.
• For every digital input signal there is the corresponding inverted signal which can also be
used for interconnection.
• Digital outputs are used for the feedback of signals such as enable signals.
Changing the view of the screen form
The view of this screen form can be reduced to the essentials via a checkbox. Changing the
function of one of the bidirectional digital inputs/outputs is not possible in the optimized view.
The view of the screen form can also be switched to a simulation mode. This switchover only
functions in online mode.
1. If you want to optimize the view, activate the "Optimize view" option.
2. If you want to switch to a simulation from the terminal evaluation, select "Simulation" in the
drop-down list of a digital input.
Parameterizing the digital inputs/outputs 8 to 15
Each of the bidirectional digital inputs/outputs can be parameterized as an input or output using
the selector.

Description
Default setting when calling the screen form the first time.
Digital inputs 8 to 15 can be interconnected with this switch position. Several in‐
terconnections are possible.
The selector can be switched by clicking from digital input to digital output.
