4.3.2 Chip card
The set parameters, the device ID and the check sum for device configuration are stored on
the chip card (for further information see chapter entitled "Commissioning", under "Use chip
card").
4.4 Reaction time
The reaction time (see chapter entitled "Technical details") of the PNOZ s50 is the time
between a signal changing at the inputs for fast (Y10/Y11, Y20/Y21) or slow shutdown
(S35, S36) and the signal changing at the outputs of the power circuit (O1+/O1­, O2+/O2­).
The reaction time takes into account the input filter time, temperature drift, spread of com­
ponents, etc.
To determine the plant's overall reaction times, the corresponding internal processing times
of the higher level safety control system and connected load must also be considered.
