Output
Description
Output
Data type: Boolean
Depends on the
Bypass
parameter and the internal logic. You need to
first connect the associated inputs to the input elements before the
output can be configured.
Table 91: Parameter
Parameter
Description
Number of inputs
(I/O settings tab)
1 … 8
Bypass
(I/O settings tab)
Bypass bridges the fast shut off function with the help of the
Bypass
input.
If the
Bypass
input = 1, then
Output
remains = 1 and the physical output
= High.
Internal logic
(Parameter tab)
You can configure the internal logic of the function block.
Configuring the internal logic
The function block has an internal logic that comprises two AND gates (enable condi‐
tion A and B) and an OR gate. The associated output is set to 1 if all conditions for A or
B are met:
Conditions for A
•
At least one input is activated for
Release Condition A
.
•
All activated inputs of
Release Condition A
= 1.
Conditions for B
•
At least one input is activated for
Release Condition B
.
•
All activated inputs of
Release Condition B
= 1.
Example of two alternative enable conditions
A safety light curtain with presence detection is protecting the work cell of a robot. The
movement of the robot is enabled as long as the safety light curtain (sensor A) is not
interrupted. If the safety light curtain is interrupted, the robot movement is only enabled
if the robot is located in a non-dangerous position (sensor B), e.g., in an offline position.
Either sensor A or sensor B must enable the robot movement.
An OR relationship of condition A and condition B can be used to configure these
alternative enable conditions.
