Where can I see the existing list of application and controller errors?

Everthing is decribed in the picture You posted. It's in the file P00.DAT.

i never used this and - never saw anyone else use it either...

one of the problems is that this can only work if one uses EXT mode (module P00 is used by CELL.SRC). also it requires you to make changes in anticipation of some specific error. to me this is useless. if something in your project keeps faulting, this is not something to be deployed anyway.

for me it is far more interesting is to see actual messages displayed on teach pendant, regardless if program is selected or not and regardless what operating mode is presently active.

for that, there are few options. one of them is to simply read entire message buffer. another is to identify specific message using ISMESSAGESET(msg_no). KUKA also has option for this called KrMsgNet

here is an example of reading entire message buffer:

DECL INT msg_count
DECL msgbuf_t mb[100] 
msg_count=get_msgbuffer(mb[])

notes:

notification messages are not managed in the message buffer (because message buffer only has capacity for 100 messages). both user and system messages are listed, however texts of system messages are not included here since they are language specific.

to get texts of those messages check robot folder C:\KRC\Help\

for example English messages are in C:\KRC\Help\en\Messages

some messages may be active but get suppressed by the HMI. check SmartHMI.exe.Standard.config

sigh... this is one sore point for many old school guys... the last time that file was updated was 17 years ago. since that time, there is no more single central document with all messages.

as a result, on-screen help is displayed. you can see them using menu Help>Messages

actual content of the messages (expanded info including remedy) is stored as individual HTML pages at C:\KRC\Help\en\Messages

message themselves (not expanded) are generated from files stored in C:\KRC\Data

initially only standard KSS messages are available. more messages may be added when tech options are installed. also manuals for tech options will cover range of applicable messages.

personally i like openness of the KSS. it is straight forward to get messages from robot and display them by your app exactly the way they look on the robot. but some work is needed to get it really perfect. some messages are suppressed - and only in certain conditions.

thanks... i was thinking that you were looking for info on message documentation (help/recovery)

btw, that list contains only the actual messages themselves (not the help on messages).

one can get equivalent list of messages in various languages from the robot. simply extract file

C:\KRC\DATA\Standard.kxz\CrossMeld_M.##.kxr

where "##" is the two letter code for language, such as EN for English.

.kxz is just a ZIP file and .kxr is an XML file

here is example of what i did with it:
