6.1 Response times in standard operation
The basis for the calculation of response times is the cycle time of the PSC1. system. During operation
this is
T_cycle = 8 ms . The response times stated correspond to the related maximum propagation
time within the PSC1 module for the specific application. Depending on the application, further
application-dependent response times for the sensors and actuators used must be included in the
calculation to obtain the total propagation time.
Function
Response
time [ms] Explanation
Activation of a monitoring function by
means of ENABLE with subsequent
shutdown via digital output
24
*)
Activation of a monitoring function by means of the
ENABLE signal.
Activation of a monitoring function by
means of ENABLE with subsequent
shutdown via safety relay
47
*)
Activation of a monitoring function by means of the
ENABLE signal.
Response of an already activated
monitoring function including PLC
processing for position and speed
processing via digital output
16
*)
If a monitoring function is already activated via ENABLE,
the module requires one cycle to calculate the actual
speed value. In the next cycle, after the calculation of the
monitoring function, the information is further processed
and output by the PLC, i.e. based on the logic
implemented this results, e.g., in the switching of an
output.

Activation of an input and switching the output
Activation of output relay via digital

Activation of an input and switching the output
Deactivation of digital output via
digital input

Deactivation of an input and therefore deactivation of the
output
Deactivation of output relay via digital
input

Deactivation of an input and therefore deactivation of the
output
Mean value filter (for setting see
encoder dialogue box SafePLC2)
0 - 64
Group propagation time for the filter. This propagation
time only acts on monitoring functions related to position
/ speed / acceleration, however not on the logic
processing.
Activation of digital output via
2 manual elements
32 ms
Activation of the 2 manual elements and therefore
deactivation of the output
Deactivation of digital output via 2
manual elements
32 ms
Deactivation of the 2 manual elements and therefore
deactivation of the output
*) On the usage of a mean value filter, its response time must be included
