Failed to connect to the PLC

[Geir 4]

Hi, I have suddenly got connection problems to my CJ2H-64EIP. PC is Win7 64bit pro. This combination has worked fine for 4 years, but now I can't connect by any means, tried direct online USB (Will sometimes connect, but CX-P crashes if PLC-program is uploaded - C++ runtime), Ethernet IP Node online, new project with Ethernet IP or USB. Communication to CX-Supervisor is also broken, so I suspect some kind of CX-Server problem. (Error "Invalid configuration: Marvin [CX-Server: MANAGER, INVALID_CONFIG, 0x822]). The PLC can be PINGed from this PC, and when I try to connect from another PC, everything is OK. I can also connect to a CS1G-43H with an ETN21 with no problems. Also tried to update CX-One to v 4.32. (CX-P v9.52) (first running the latest CX-Remover). The CXServer Driver management tool reports device driver v5.2 with my PLC listed. I have also tried to roll back some Windows updates, but the oldest restore point I could find did not help. Finally, when I try to load a program for this PLC from the disk, CX-Programmer crashes, same as above when uploading. Any ideas? Geir

Hi...these are always very difficult problems. Seems like you have different issues, one being CX-Server is somehow messed up, other CX-Programmer seems to have a problem on its own. The problem with CXP might be that there's something wrong or missing related to the Component Profile Sheet. It needs such a CPS file for every product to correclty display and process its specifics. When this file is missing I have experienced CXP to crash however I would usually get an error. You can try having a look here: C:\Program Files (x86)\Common Files\OMRON\Profiles\CPSFiles I attached the CPS files for CJ2H-64 from my disk. Extract them in this folder and see if it helps. For this reason it's good practice to run CX-One from VMware. It allows you to easily roll back to a healthy base when you run in to problems. CPS CJ2H-CPU64.zip

Thank you, I tried to replace my CPSfiles with yours, but no luck so far :( The error message when CX programmer crashes is: Microsoft Visual C++ Runtime Library Runtime Error! CX-P.exe abnormal program termination. Geir
