Data exchange between CPU DP and PN (S7300)

Aligasifier Posts: 30 Rating: (0)	Good morning, I am trying to exchange data between 2 CPUs, one is DP and the other PN, a)Is it possible to exchange data between them?I am using USEND-URCV, but it does not work. b) I am trying to get the exchange followitng this link: https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=22791526&caller=view In the sender CPU (PN) it shows the values when I go online of the ID, RD_1.. so it seems to stablish some connetion, but in the receptor CPU is shows nothing when I go online,I can not find out why. c)i do not understand how can I activate M0.3 in OB100, as they explain in that link : "The value of the "EN_R" input parameter is always "1" because the marker M0.1 is set to the value "1" in the startup OB100. In this way the S7-300 station is always ready to receive" This is my code for the receptor, ` CALL "URCV" , DB12 EN_R :="START-UP" ID :=W#16#1 R_ID :=DW#16#1 NDR := ERROR := STATUS:= RD_1 :=P#DB8.DBX20.0 BYTE 135 any idea why is does not work?Any help would be really great, Thank you
