Hi! I have the same problem but in my case the "Enable put/get" check is checked. In fact, the put funcition is working fine, the problem is only with the get function and the error is the same: 2 = "Negative acknowledgement from the partner device. The function cannot be executed" Any idea? Thanks and regards, ------------------------------------------------------------------------------------------ |

Thank you for your support. Please find attached de zip file with many screenshots. I have made a lot of tests. Sometimes the put works, sometimes the get works, sometimes none works and sometimes both works; and I am only changing the number of bytes, compiling the PLC project and downloading it (remember that it is PCS7 with a S7-410-5H). No changes in the user DBs, no changes in the netpro. At this moment, the get is working with 4 bytes and the put with 2 bytes. If I increase the number of bytes it does not work. An the question is that on monday we could communicate up to 132 bytes. Regards, P.S.: I said "Bingo" because I was expecting this kind of funny errors AttachmentScreenshot.zip (547 Downloads) |
