6 Replacing a Defective Slave / Automatic Address
Programming
If the indicator AUP is lit in the protected mode, it indicates the following:
Exactly
one
slave has failed.
Automatic address programming by the CP 242-2 is possible.
You can now replace the defective slave as follows:
Remove the failed slave from the AS-i cable. You can identify the failed slave simply by the
flashing LED assigned to the slave in the front panel display. First, press the DISPLAY button
to change the display of the CP 242-2 from the status display to the slave display. The first
group of 5 slaves is displayed. By repeatedly pressing the DISPLAY button, you can display the
remaining slave groups one after the other.
Replace the defective slave with an identical slave with address 0 ( as supplied). The CP 242-2
then programs this slave with the address of the original station that had failed.
The “AUP” indicator then goes off. The CP 242-2 indicates the new slave in the LED display.
Note that “automatic address programming” is only possible when:
The “AUTO_ADDRESS_ENABLE” flag is set to 1.
The CP 242-2 is in the protected mode.
Only one slave has failed.
