Identifying ARNC0 Error in Logger

Hey there I got this Error on my Logger and it makes my program won’t boot up, what does it mean? can someone help me please

Hello,

could it be that this is a quite old project? Can you give some background what lead to this Error.

(2ten Error Line states an Index of an Interface)
(3ten Error Line talks about no Mode defined)

My guess is that you have a very “old” virtual interface in your Configuration.
And this Virtual Interface has a Configuration called “Mode”.

I hope this goes in the right direction. Please have a look in the file in your Automation Studio Project.

After I check, I don’t have Virtual Interface in my Arnc0cfg, should I add it?

Hello,

no i don’t think it is usefull to add it, because in modern days we don’t use it anymore.
Lets first diagnose bit more…

  • Are we sure the Project and the System are identical did you check “Online Compare” or did you transfered lately.
  • Was the system ever running before?
  • Which versions do you use “Change Runtime Window screenshot?”
  • Can you upload a complete logger instead of only a screenshot. Is there maybe more to see.

Greetings

  • No I haven’t transfered it to a real PLC, so I can’t do an Online Compare
  • Here are the Change Runtime Window:

-Here are the complete logger:
Logger.zip (21.5 KB)

After I checked I forget to add a SDC Configuration for the AcpSdcmap, now it can boot up, but it still have that Error.

I also check the original program that once used in actual PLC also have the same Error, I think that Error doesn’t affect my boot up problem, but still it would be nice if I can fix that Error

Hello,

The error does only affect the NC-Manager but it don’t affects the PLC Operation State “Run/Service”…

ok there is not much more in the logger, but i got now that it states “Nodes”, so it definitly does not come from the previous discussed “mode”. That was only bad reading in the picture.

I could now reproduce the error in my local test project. It started to occure after removing CNC_Enabled=“1” from all ACP10 Axis. So there is no Axis the ARNC0 could use.

The ARNC0 is telling us that on his interface he could not find a “node” = “axis” which is enabled for CNC-Operation.

The error vanished if i disable all ARNC0 channels.

  • Can you please check your ARNC0mapping?
  • Do you use a CNC-System on this PLC?

Greetings

Sure these are the mappings:


And no, I don’t think I’ll use CNC for this project.

These are the ACP10 mappings. I meant the ARNC0 mapping.

Arnc0map.ncm

Do you have this file?
