Hello,

Perhaps these links might help:

How do you program communication blocks FC11 and FC12 for the PROFINET IO controller?

- You need 1 call of both blocks.

- You need the amount of bytes to be mapped in Datablocks. You communicate through CP.

Best regards,

Thank you for your replies. I have continued working on it again now. I still don't get why I have to use PNIO rec/send. If I just write the address of the input on the ET200SP in my input program, wont I get the sensor signal in the CPU?

Thank you in advance

Than you for the fast reply. I have 4x16 In on the ET200SP., no output. 

So I guess I only need the PNIO_RECV block. 

Which address is I have to put in CPLADDR? I cant seem to find it.

The mode I have put to 0, as it is a IO controller

LEN = 8 byte as I have 64 input?

What about RECV on the block? Is that the DB i devote to the sensor signals?

Thank you

So about the CPLADDR. In the IO addresses setup of the CP343-1 it has Input start 512. So I guess CPLADDR shold be 200 hex?

 yes.

The DB should be so big that your highest address also can be read out. Examples:

you just have addresses from 100..115, then your DB should have at least 116 byte.

When the adressess are from 200...223, then your DB needs to have 224 byte.

When you start at 0 until 16, the DB just need to have 16byte.

The blocks starting to write and read from address 0.

hope this helps,

regars,

 When you say the DB has to be as big, do you mean the DB where the data is transfered to? In case i guess I could change the CP343 address to 0-15 and have a 16 byte long DB?

Another thing is that I have two ET200SP with 64 inputs both connected to the same CP343-1. How does it distingues between them?
