4.18 Reaction times of local signals
Typical reaction time of the local input and output
The typical reaction time is the time that is required to transmit information from the sensor to the actuator, if
the overall system is working without error in normal operation.

Definition Description
RTSensor Response time of the sensor, until the signal is made available at the interface. Typically
provided by the sensor manufacturer.
RTInput Reaction time of the EK1960 safe input. This time depends on the parameter settings of the
input module. In this case from the setting Channel x.InputFilterTime.
RTLogic Reaction time of the controller. This is the internal cycle time of the controller and typically
ranges from 500 µs to 10 ms for the EK1960, depending on the size of the safety project.
The actual cycle time can be read from the controller.
RTOutput Reaction time of the output. This is typically between 2 and 3 ms.
RTActor Response time of the actuator. This information is typically provided by the actuator
manufacturer
The typical response time is based on the following formula:
4.19 TwinSAFE reaction times
The TwinSAFE terminals form a modular safety system that exchanges safety-oriented data via the Safety-
over-EtherCAT protocol. This chapter is intended to help you determine the system's reaction time from the
change of signal at the sensor to the reaction at the actuator.
Typical reaction time
The typical reaction time is the time that is required to transmit information from the sensor to the actuator, if
the overall system is working without error in normal operation.
