Hi all,

I’m a ABB robot newbie.

I want to display any error code on a HMI connected to a Allen Bradley PLC. I have created an unsigned double integer and used the following code  
ERROR  
SetAO ErrorCode, ERRNO;  
ENDPROC

But the received code does not match the error codes in the manual. Does anyone know of a way of doing this. I did thing about doing a lookup table, but with the vast amount of possible codes, this would not be a great way of doing it. I also was wondering if there is any way of converting the ASCII (I assume this is the format) in the IRC5 to a decimal number that matches the fault code.

Many thanks for any suggestions.

Dave

An analog output is not appropriate for sending those numbers. Use a group output and a dint is probably not necessary either, but that is up to you, probably num is sufficient.

You had the right idea - just use a group output and SetGO instead.
