Except the string I was getting, on the table you linked to, which I had also linked to at the top of this page, after having read it, was not on that table. There’s a fundamental disconnect in the information there. You get that right? If there’s a table telling me ‘These are the strings and values’ and I’m not getting a string from that table, I have to assume it’s not to be referenced in the table.
‘Bad Quality’ provides no more information than I should already have by the time I’m checking the quality. It’s useless. Tautological.
The expression in the tag generated an error during execution. The error log should provide more information on the error.
This is a useful error code and string and explanation. It tells me what is up and where to go to begin solving the problem.
I’m going to do my best to sum up what I think the answer is, but no one seems to be at all sheepish or embarrassed about giving it so I’m not sure I’m getting it. (I would be):
There are a number of codes. There’s a table of codes. It’s existence implies it should be consulted.
The table is incomplete. A very common result is not in the table. The very common result does not provide any information that is not provided by the tag not working.
I got the very common result, which could be made more informative simply along the lines of ‘unknown error’ and spent the day on a wild goose chase trying to reference it off an incomplete table based on an assumption that information provided in a manual would be complete, and got a wild goose chase with people telling me to typecast a string I’d already pulled and pasted into a string and to consult a table I’d already consulted?
‘Bad Quality’ is a part of the table, but is not listed. It has a value, but no qualities’ value can be found outside the table, which this one does not appear on. Unlike most all other entries in the table, it does not provide any more granular information and if a tag’s quality is ‘bad quality’ it is on the user to locate the error because it’s outside Ignition’s diagnostic capability, yes?
If I seem frustrated it’s because I am. That penultimate paragraph could have been given and saved everyone time.
