SICK safeVisionary2 - Settings for Monitoring Cases; Defining Input Conditions; Configuring Cut-Off Paths; Empirical Values for the Required Input Delay

Input delay
In t
he Input delay field, you can select a delay for the inputs.
If the control device that you use to switch the static control inputs or parity inputs
cannot switch to the appropriate input condition within 12ms (for example because the
stable output state is not achieved until later), you must configure an input delay. The
selected input delay must be large enough to allow your control device to switch to the
new input condition within this time.

7.12.2 Settings for monitoring cases
Name
In t
he Name field, you can enter a meaningful name for the monitoring case. If you
create a lot of monitoring cases, you should consider a naming concept that makes
it possible to identify the monitoring cases easily (for example right cornering, left
cornering).
Sleep mode
If y
ou activate this option, the device changes into sleep mode as soon as the input
conditions for this monitoring case exist.
7.12.3 Defining input conditions
Overview
F
or each monitoring case, you choose the input conditions for which the monitoring
case will be activated.
Prerequisites
•
T
he inputs that are in use are selected.
Approach
b
S
tatic control inputs: In the Input condition column, click on the fields with the input
conditions (1, 0 or any) until the desired condition is displayed for each input and
each monitoring case.
b
Parity inputs: Select the input condition in the drop-down menu.
✓
The input conditions for the monitoring cases are now defined. Combinations
which are invalid or already assigned are marked.
7.12.4 Configuring cut-off paths
Overview
You can create cut-off paths and define the outputs switched by the cut-off paths.
