Example
The following examples shows the determination of the response time of a safety function (sensor – logical
function – actuator).
Tab. 12.4: Response time of a safety function
Sub-function
Response time of the sensor
Test time for testable sensors, e.g. Type 2 contact-
less safety devices
With testable sensors, the response time increases
by the active test gap + 12 ms.
Thus, with a test gap of 4 ms, there is an additional
response time of 4 ms + 12 ms = 16 ms
Filter time
When the ON-OFF filter is active, + 8 ms
Standard time
Controller module input to controller module output
With a cycle time of 4 ms.
Logics for switch-off delay times
If function blocks with switch-off delay are used in the
logic plan, then these times have to be added to the
response time.
Actuator response time
