Hello guys, looking for ideas on what could be wrong. 1. The plc and the pc, plc and hmi are connected via a router. They are all in the same subnet and have same IP adressess (last number is not of course). 2. I can build projects and do programming via Tia portal V17 to each device normally. That means if i program the plc it will go online and download the project, do its logic etc. If I build a project and download it to the HMI it works OK. Problem starts from part 3. 3. I made a makro (button) on a HMI screen which sets a boolean tag to 1 or true in the global data so i can toogle another tag (energize it basiclly). So both "tags" are in global data and the problem occurs each time I press the "button" i get an error message 190011 the tag could not be written to a plc or something. With a few other simulations i have deduced that there is no communication between HMI and PLC only to my PC. 4. They (PLC and HMI) are connected in topology and network view and everything seems fine to me in the Connections. PLC is configured so that allows full access. What bugs me further is that even if i try connecting my plc directly to the HMI (ethernet cable) it's all the same. Even after restarting both devices, rerunning the runtime etc Note that i havent had any problems using PLC SIM and WIN CC SIM in the past, only the physicall devices bug me:/ Link from wetransfer with pictures [snip] If anyone can help i would be most grateful, best regards from Slovenia Almir Attachmentwetransfer_connections-png_2022-01-23_1325.zip (165 Downloads) |

Delete the connection and make a new with the changed IP addresses of the devices. |
