NOTE
•
Using multiple sampling you can increase the availability of a system.
•
The multiple sampling can be configured in the CDS. A specific multiple sampling
value can be set both for the configured field set and for the simultaneous field
set in each monitoring case.

Simultaneous monitoring
Overview
Using simultaneous monitoring, the S3000 can monitor two field sets at the same time
(e.g., a hazardous area on the left and a hazardous area on the right) within a monitor‐
ing case.
Approach
1.
On the
Cases
tab, select a further field set as a simultaneous field set within the
relevant monitoring case.
7.11.4
Checking the monitoring case switching
To check the switching between monitoring cases, configure a series of monitoring
cases. Either an arbitrary sequence, a unique sequence, or two alternative sequences
can be defined.
•
Arbitrary sequence: It is allowed to switch from one monitoring case to any other
defined monitoring case.
•
Unique sequence: It is only allowed to switch from a monitoring case to another
specifically defined monitoring case.
•
Alternative sequence: It is allowed to switch from a monitoring case to one of two
specifically defined monitoring cases.
NOTE
Use the monitoring case switching check as an additional check on the control. For
example, to detect deviations of a vehicle from a corridor, or deviations of a system
from the prescribed production process.
