Dealing with Problems / Error Displays

This chapter contains information about special operating states of the CP 343-2. It
is intended to help you to deal with problems.

7.1

Replacing a Defective AS-i Slave/Automatic Address
Programming

Simple Replacement of AS-i Slaves

Using the automatic address programming function, you can replace failed AS-i
slaves extremely simply.

Note

Remember that “automatic address programming” is only possible when the CP
343-2 is in the protected mode and only one AS-i slave has failed.

Slaves with profile CTT5 (multiaddress slaves) do not support automatic address
programming.

The sections below explain how to replace failed AS-i slaves using the automatic
address programming function.

Detecting a Defective AS-i Slave

If the AUP LED is lit (only in the protected mode) this indicates the following:

Exactly

one

slave has failed.

Automatic address programming by the CP 343-2 is possible.

You can recognize the failed AS-i slave simply because the LED assigned to the
slave flashes on the front panel.

Replacing a Defective AS-i Slave

Replace the defective AS-i slave with an

identical

AS-i slave with address

zero (default address).

The CP 343-2 then programs this slave with the address of the original station that
had failed.

The “AUP” display goes off. The LED in the slave display of the CP 343-2 module
indicates that the slave has been included.
