Dear Duris, I had attached the video. In this video, I had update the TIA portal V16 with update 6, but problem still persist. For your info, actually previously I have experience on Modbus RS485 for S7-1200, which is using same function block "MB_Master", which able to read the data successfully. So I don't know why S7-1500 unable to read the RS485 data. Your helping & advise is highly appreciated. Thank you. Best Regards, Jay AttachmentUnable to change the Port to 272 (Video).zip (144 Downloads) |
