Hi,

I tryed to read port diagnostic of scalance X204-LD thru CP343-1 but SFB52 return error 16#C0809000.

I tryed the same block and code when scalance is linked onto integrated PN port of the CPU and it works.

I used the document attached to create the code.

I'm using :

Step 7 V5.5

CPU 317F-PN/DP

CP343-1 (1EX30)

Scalance X204-2LD.

Any ideas ?

Regards.

Hello,

only idea, if you want use CP card, probably need call other blocks not same as with integrated PN CPU port. This looks like FB52 (Simatic_NET_CP library hope) is alternative in this case, look to page 12.

It works with FB52. I have read this section but I thought that FB52 is an alternative and not mandatory when I use CP343.

Thanks.
