hi MrBooth, CPU goes into Stop because there is no OB121 loaded. This OB is called when the CPU detected a programming error. load the OB121 and the CPU will not go into Stop. have a look into the event #2. it is obviously. Access address: 2051. At first, there is no such address. At second the DP_SEND/DP_RCV blocks don´t work with the diagnostic address. Have a look to this FAQ/application sample: What should you watch out for when configuring a CP342-5 as DP master and why is it necessary to call the FC1 "DP_SEND" and FC2 "DP_RECV" functions in the user program of the CPU in order to transfer data?hope this helps, regards, |

Thanks Mop, Yes for now that is what I want to do. just want to have a work DP Network so I can run some diagnostic tools like Profitrace... I guess you just want to access IO-addresses over the internal Profibus interface, right? AttachmentModule Information.pdf (204 Downloads) |
