Hello PLC; You mentionned a problem with the instruction PNIO_RECV, but the image you posted refers to PNIO_SEND. Please take a screencapture of the PNIO_RECV network in your program, preferably while you are online with the CPU. Here is the initial description of PNIO_RECV from the Step7/WinCC manual, v15.1, the information should help you with all versions of Step 7 TIA Portal. https://support.industry.siemens.com/cs/ca/en/view/109755202/45784041355 If you look n the navigation column at the left of the manual page this links opens, you can gather more information that will help you understand what the combination of NDR, Error and Status outputs means for your application. Hope this helps, |
