Updated, now that I’ve found out how to directly enter a character code
Updated again. I’ve lost all the uploads to this site, so while the tables might still be useful, you’ll need to generate the characters youself if you want to see them.
If you’re the curious type (quite possible) and you’ve been playing with an Allen Bradley Micro810 (less likely) you might have wondered what special characters you can put on the screen.
And you’d stay curious if you tried to find the answer in the Allen Bradley Documentation, because it’s shit: It doesn’t even tell you how many characters there are on a each line. Incidentally, the answer is 16.
So, in an attempt to remedy the situation, I wrote a simple program which displays every character. Unfortuantely this was lost, but it shouldn’t be hard to re-create it. You will need Connected Components Workbench.
Entering the characters into strings is pretty easy – just type $ followed by the 2 digit Hex code. e.g. ‘Hello$21’ would appear as Hello!.
The first 32 are dramatically different to the ASCII standard, and well worth knowing about, but there are a few others different 5C,5E & 7F. Codes 80 to FF are less useful, but there are a few accented characters in there that might be of use, depending on which language you use.
Characters 00 – 3F (0-63)
