Remove field set from a monitoring case
In the monitoring case editor, you can also define the monitoring cases with input con‐
dit
ions and assign the field sets.
7.12.1 Settings for monitoring case tables
Name
In t
he Name field, you can enter a meaningful name for the monitoring case table.
Inputs used
You choose the inputs that you would like to use for switching between monitoring
cases in the monitoring case table.
Input delay
In the Input delay field, you can select a delay for the inputs.
If your control device, which you use to switch the static control inputs, cannot switch to
the appropriate input condition within 12 ms (for example because of the switch’s
bounce times), 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.

Tactile controls (relays) 30 ms to 150 ms

Importing and exporting monitoring case tables
If y
ou need identical monitoring case tables across different projects, you can export
monitoring case tables out of one project and import them into another project.

7.12.1.1 Switching order
Overview
Y
ou can specify the order in which the monitoring cases can be called.
You can specify one or two subsequent monitoring cases for each monitoring event. If
you do not specify a subsequent monitoring case for a monitoring case, then any moni‐
toring case may follow.
If input conditions are present which do not call up any of the defined subsequent mon‐
itoring cases, the safety laser scanner switches all safety outputs to the OFF state.
You can specify the order of the monitoring cases as a process or in individual steps.
