I tried to exchange data between CPU 319 and 315(CP343-1 Lean) using PN-IO (FC PNIO_SEND and PNIO_RECV) over fictive area, but nothing happened

The CPU 3xx-PN takes initiative here, using PUT and GET The usage is explanined here: http://support.automation.siemens.com/WW/view/en/18610307 No extra program in the system with the Lean CP 2) a secondway is to declare the system with the Lean CP as IO device of the CPU3xx-PN acting as IO controller. The both sytems will echange data over fictive I/O In thewith the Lean CP, ou must use special PN - FCs See http://support.automation.siemens.com/WW/view/en/31764614 It seems that you have two separated projects. It is easier to put all together in one project. Hello, Idownloaded thesecond option from Siemens support, suggested by Edr, to test it using PLCSIM 5.4 SP3. I triedto exchange databetween CPU 319and 315(CP343-1 Lean)using PN-IO (FC PNIO_SEND andPNIO_RECV) overfictive area, but nothing happened.I used the VAT for both CPU to monitor/modify values, but withoutsuccess ! Both CPU remain in RUN mode, without any error but I can´t see the changed data. What could be my mistake? Is possible to test it using PLCSim ? Best regards.

One thing to note over and top ofthis is: You MUST use the relased SFB's and can NOT use their S7-300 counterpart FB's (even though they internally use the relased SFB's they will not work to simulate comms). I hope this helps
