Group delete of ascii characters in compaxtlogix

Hi All

Im having a small issue with manipulating ascii characters once in my Compactlogix PLC.

I have an external source writing a load of data to the serial port on my controller. I take the data from the buffer, placing it in a custom string tag. This is then cut down to leave me with an 11 character string. This string is in the format 'a b c d e d' with a space in between each character, (this is how i receive the data).

Is there a way to remove all the spaces at once rather than using 5 delete functions for each space?

Best Regards

Oliver

The only thing I can think of is to do a FIND and search for a space. Then do a string DELETE. You could do a small routine that just takes the every other letter out of the string and CONCAT them into a string.

CONCAT test.DATA[0] TESTE.DATA [2] TEMP CONCAT test.DATA[4] TEMP TEMP CONCAT test.DATA[6] TEMP TEMP CONCAT test.DATA[8] TEMP TEMP CONCAT test.DATA[10] TEMP TEMP
Then TEMP has your data with no spaces

Ive written a similar routine just using delete's instead of concat's which works, but just a bit messier than I would have liked.

Thanks for your help.

Sorry I should have started up 5000. You can't specify to the Data location. DATA[0]

I guess DELETE is your best bet.

Nothing wrong with this; the upside is that someone reading the logic later will know exactly what you are doing - verses scratching their head over some trick code that is hard to read.
