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 response time
The typical response time is the time required for transferring a piece of information from the sensor to the
actuator, when the whole system operates normally, without error.
