Dear Stefan, like mentoined in the other post im german forum, i think we need some more specific information what should be done exactly. Because if we are talking about a PROFIBUS slave like an ET200S with I/O's, maybe a FLD connection is not the correct way to go in this case. And the screenshot looks like a standard slave for me. But in general the 240 byte is a limitation by PROFIBUS itself. What properties, advantages and special features does the FDL protocol offer?

Thanks for still being alive and answering that quickly I got stuck with FDL because the manual for a CP only lists more details here, but I didn't realise there are several technologies. Here are the main devices:
Engineering done in: PCS7 V9.0 (SP3) As I have learned, a slave can read only 244 Bytes, so if I want to read 300 bytes I have to use 2 Slaves
If a single device shall read those bytes it has to configure with multiple Profibus Slaves. Is it as simple as that? I have sketched it, and that says more than a thousand words :), it would be Option 2, in that case. thank you stefan |

is it answered in PCS7 V9.0 (SP3) - can a single device read 300 bytes? - 287541 - Industry Support Siemens |
