Configuring the AS-i master
The CP343-2 is taken from the hardware catalog in STEP 7 HW Config just like any other
module and placed in the required slot in the rack of the S7-300 station.
After you have inserted the CP343-2, there are still no AS-i slaves configured. In this default
setting the rules of "button configuration" apply initially.
To view general information, addresses and operating parameters and to configure or modify
them, change to the properties dialog of the CP343-2 in STEP 7.
Figure 6-27
The start addresses for both the inputs and outputs must be identical. The default setting for
the reserved data length is 16 bytes.
Operating parameters
Automatic address programming is set by default, i.e. if a slave is replaced due to a fault, the
slave that replaces it will be automatically assigned the previous slaves address. If this
action is not required it can be deselected.
