Please help. I'm trying to establish data exchange between S7 300 (CPU 315-2 PN/DP) and PAC 3200 with extension module for Profibus over Profibus network. I'm programming in Step 7 V12 SP1 Professional. The installed version of the gsd file for PAC is GSD_PAC3200_V24 (which I've downloaded form Siemesn web pages http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objId=27552047&nodeid0=10805055&load=content&lang=en&siteid=cseus&aktprim=0&objaction=csview&extranet=standard&viewreg=WW). In attachemnt there are some screenshots that show that the communication is established (also the diagnostic of the PAC is showing DATA_EXCH - Configuration is OK. Data is being exchanged with a class master 1). The only problem is that everything that the CPU is reading is 0 and that is not correct because the PAC is showing some measurements. If anybody has any idea, please reply. Thanks, Igor
