Hi All,
As part of a bigger project and not being too familiar with S7 I'm trying to send & receive data from datablocks over Profibus between a 315-2DP (Master) and a 313 with a CP342-5 Card (Slave). There is a Siemens Document details most of this and there is a lot of info on tips for communicating with the 342-5, all which I have examined.
At the moment everything looks good (No fault lights or diagnostic issues) The data transfer simply isn't occurring by looking at the datablocks online and I'm unsure why. The code can be downloaded at http://code.google.com/p/plc-code/downloads/list (just to big to upload here) below if anyone is interested and is bare-bones containing only the essentials, I imagine its a configuration issue.......
