Configurable functions
You can configure the monitoring cases in the CDS.
Each monitoring case includes …
the input conditions, the so-called control signals, that control the activation of the
monitoring case.
a field set, comprising of protective field and warning field or fields.
if necessary, a unique follow-on case or two alternative follow-on cases.
the multiple sampling for the field set.
Monitoring cases can be switched with the following input information:
static information
velocity information
a combination of both
4.10.1 Monitoring case switching via static input information
For monitoring case switching via static input information, configure for each monitoring
case the input condition to be used to switch to the monitoring case.
WARNING
When switching the monitoring cases using static control inputs, please note the
following points:
Ensure that the control for the monitoring case switching has the required level of safety.
Ensure that the circuit for the control inputs is suitable for the ambient conditions to be
expected so that systematic and design-related effects and resulting errors on the
switching of the monitoring cases can be excluded.
Ensure that the control — using static control inputs — provides switching between the
monitoring cases in the correct time frame. Note that at the time of the switching there
may be a person in the protective field. Only by means of switching in the correct time
frame (i.e. before the hazard occurs at this point for the person) is protection provided
(see section 5.6 “Time for monitoring case switching” on page 71).
