I'm a beginning programmer and I have some problems to send data between a CPU 416-2 and CPU315-2 DP. I want to send 400 bytes from a DB in the CPU 416-2 to the CPU 315-2 DP through a profibus cable. I need to program this in Step7, the simatic manager. I've got also a CP342-5 card for the CPU 315, but I don't have a CP 443-5 card for the CPU 416. I have set a S7 connection between the CP 342-5 and the CPU 416. By checking this connection in NetPro, the connection status is green (Set up), so this looks good. I used the folow link as example to send 8000 bytes with BSEND/BRCV: https://support.industry.siemens.com/cs/do/en/view/18516182 But the BSEND and BRCV gives me an error = 1 and status = 1, this means:
I checked everything, but I don't find any problem. Maybe there is a problem with the CPU416 and isn't it possible to use BSEND? Or do I need to buy a CP443-5? Is there a better/ easier way to send 400 bytes data from the CPU 416 to CP342-5? I attached my project. Thanks in advance for your help. AttachmentCom_cpu416_cpu315.zip (36 Downloads) |
