3.1
General Information on Configuring the CP 343-2 with
STEP 7
Significance of the Configuration in STEP 7
Configuration in STEP 7 is necessary for the use of the CP 343-2 in an S7-300.
Here, a distinction must be made between the obligatory basic configuration and
the optional slave configuration for the CP 343–2 P.
The following applies to the CP 343–2 P:
While configuration with the buttons as described in Section 1.6 simply allows
querying of the current actual configuration, by configuring in STEP 7, you can
create a defined configuration regardless of the actual configuration and download
it to the CP.
Note
The information on the basic configuration in Section 3.2 applies both to the
CP 343-2 and to the CP 343-2 P.
The information in Section 3.3 relates only to the CP 343-2 P!
3.2
STEP 7 Basic Configuration
Entering the AS-i Master into the S7-300 Station in HW Config
The CP 343-2 / CP 3 43-2 P 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 CP 343-2 / CP 3 43-2 P, there are still no AS-i slaves
configured. In this default setting, the rules of " button configuration" apply initially
(see Section 1.6).
