Good morining, I bought new PLC last week and i can’t conect with it. It seams to me that my pc doesn’t see that i connected the plc. I downloaded wago ethernet setting but it also can’t seem to find the plc. The plc itself shows that everytching is connected in the matter of ethernet conection. So my question stands what do I do now. I thougt about just buying the wago comunication cable but it is the last measure for me. I dont undrestand why my pc doesnt see it at all. If it changes sometching, the “Run” LED lights red up, but I think it should because the PLC has no program. Another thing is that the I/0 blinks in a sequence of 4-8, but it has to do with my inputs, because one of them is probably inactive.
Error code 4-8 indicates an interruption in the internal bus after the 8th module. Do you have an End Module (750-600) at the end of the node? This is required.
No i do not have one. Do you think that this may cause all the issues with connecting plc to my computer?
Did you assign an IP address to the PFC? It needs to be on the same subnet as your laptop.
You can temporarily assign the IP address 192.168.1.17 to the PFC by setting the mode switch to STOP and holding down the RST push button for more than 8 seconds.
The SYS LED will flash orange when the temporary assignment is in effect.
You can then access the PFC’s built-in web pages using a web browser with the temporary IP address (username: admin, password: wago) and assign it a static IP
Yes i tryed rst but the ip in the configuration doesn’t change. When i try to go to the web side it show me this site is unreachable.
Okey thank you. It helped. My computer now sees the PLC. My problem was that I did rst in Run mode. But I have another problem, Codesys can’t find my PLC, I downloaded everything from the Wago website and selected the right model in Codesys, and when I scan, it doesn’t appear
Okey. I fixed it. It seams that I had to reinstall wago upload and add again wago Firmware PFC_V040601_28 when i did i started codesys and plc again and it connected. But anyways thank you all for help and support.
