But now come problemwhen I download configuration in PLC can't read and write analog outputs integrated and on the extended cards.It seems like CPU can't see that have analog outputs in the system when I try to monitoring this analog outputs. Try also to config with manual addressing using memory area bytes from 0 to 127 but no result PQW xxx is unreachable. Can someone explain me ware is a mistake.

I don’t use this type AO cards to this moment. Can you explain me how I can write memory to this type of AO I can’t use this example: L MW100 T PQW752 It’s generating CPU STOP. This CPU 6ES7 313-5BE01-0AB0may be not use P memory area but now come question what memory area use? Is it standard QW memory area? I remember that in one project have similar problem with this card 6ES7 332-5HD01-0AB0 (4AOx12bit) with CPU S7-4162DP so problem must be not in CPU.Or have some specific function for write PQW xxx. 10x in advance.

Second, make sure that the firmware version of the CPU coresponds with the one from Step 7. I had a problem like that with a S7-313C.Whenever I tried to update the hardware configuration , the PLC could be put in Run mode but it did not do anything. The HW config used by Festo for the CPU wasn't in the standard S7 libraries. So I downloaded the HW config from a similar platform and uploaded it to this one . That solved the problem. Thirdly , if you have problems when you try to convert analog inputs to INT , do some operations and then reconvert it to W , you might try declaring the PIW as INT and the PQW as INT also, and avoid conversions( example : in the Symbol table : adress PQW 256 data type INT ). If none of the above work , please post more details about the problem or if you solve the problem , tell me how. Good luck!
