CP343-1 hardware configuration

Hello guys,

I have to config a Hardware with PLC319-3PN/DP and 2 CP343-1(6GK7343-1EX30-0XE0) on the same rack.

When I insert PROFINET-IO System for each CP343-1 and compile it I get this error:

" The system data could not be created because the configuration is inconsistent"

with only one PROFINET-IO System I don't have this error

I attached a pictures with my hardware configuration 

Hi,

first I checked you CP343-1 if it compatible with you PLC - it does.

It´s just a guess:

Your CP343-2 is connected to slot number 5, this means it uses base Adress 272 and a length of 16 bytes. Please check if there is any other Adress in this area. In most CPUs (for example, the CPU 315-2DP, 318), the slot-oriented addressing can be modified with STEP 7 configuration (HW Config).

Also check manual on page 24:

Hello,

on S7-300 is not possible to use 2 CP 343 in IO-Controller mode!

Only one CP can be used in Controller mode.
