Of course this is besides the "SYNCHRON" calls in the Startup OBs. WinCC 3964R driver can access any of the CPU Data Blocks through any of the interfaces, if both are enabled on S5 side.To enable the Link you need to : a)RK512+3964R Drivers are loaded inthe interfaces of CP-525 b) CP-525 ports are synchronised to CPU with the "SYNCHRON" call in startup OBs c) " Send All" / "Receive All" are called in the CPU cyclically / Time interrupt OB. However you should remember that when both the interfaces of CP-525 are used, each port supports only 9.6kbps speed. If single port is used, you can go upto 19.2kBPS Hope this helps Navnag
