Siemens SIRIUS 3RK3 - Replacement of Multiple AS-I Slaves During Running Operation

7.10.3 Replacement of multiple AS-i slaves during running operation
WARNING
Loss of the safety function through changes to the system.
Can Cause Death, Serious Injury, or Property Damage.
To ensure the safety of the system, any changes to it or any replacement of defective
components must be followed by a thorough and successfully completed function test of the
system.
A complete function test consists of the following tests:
• Con󹪝guration test (test of the con󹪝guration)
• System test (wiring test of the connected sensors and actuators)
When multiple defective AS‑i slaves are replaced, the defective AS‑i slaves can be replaced by any
new slaves if they are of the same type and have already been assigned the same address.
If the new AS‑i slaves have not yet been addressed, each must be addressed in succession
through an AS‑i master with the autoadressing function to apply them to the system.
In the case of safety-related AS‑i input slaves, the sensor must be operated once to teach the new
code sequence. Non-safety-related slaves are interpreted according to the con󹪝guration.
Automatic teaching of code sequences in the background
The transmitted code sequences are learned in the background by the system. The TEACH-LED
light up yellow when all code sequences have been taught. The code sequences of all taught
slaves can be saved in the code sequence table by pressing the reset button for 3 s or by pressing
the "Adopt code tables" button in the "Target system" > "ASIsafe code tables" dialog box in Safety
ES.
You will 󹪝nd further information in Chapter "Teaching the code sequences (Page 208)".
