I have an MSS demo unit connected via Profibus to a 315-2AF03-0AB0 processor. The Profibus address of the MSS is 10 (decimal). I am trying to access the MSS diagnostic data through the block SFC 59. I have created data block DB1 with a length of 3 bytes and assigned it to RECORD. The error I continue to get at RET_VAL is 8729. I have attached an archive of my file if someone is willing to give me some guidance on how to fix this problem AttachmentProfibus.zip (77 Downloads) |

Hello Swright, Change value in LADDR ( doesn't means profibus address ) from A to 3FF. Explanation of this you will find there: Parameter assignment of SFC 103 / SFC 59 required for identifying and reading out topology data regards |
