Hello, As such, a DP slave is always limited to max 244 bytes in/out as per Profibus DP standard. However, at application level, you could imagine to implement a kind of application protocole allowing you to multiplex the data. This is in my opinion what you can do with that module. Have a look to that manual here: http://www.prosoft-technology.com/content/download/759/6759/version/3/file/pdps_driver_manual.pdf They describe a "dabase paging system" as of page 17. Here an extract " ... the PDPS driver recognizes a special command code in the PROFIBUS protocol that causes the PDPS driver to write to, or read from the Database range word 400 to word 3999. This feature opens up to the user the whole capacity of the PDPS module's Database. ...." |
