Parsing strings in Control logix 5000

[Jdhillon 0]

I have an application, where I have to receive 7 strings of data from a SLC 505 into Logix 5000 and split it into blocks of 12 bits and send them to display in ASCII. Any advice will be appreciated.

[panic mode 246]

so...where is the problem? receiving? handling 7 strings? decoding? converting to ascii? sending?

Handling 7 strings

[TConnolly 13]

The SLC and the CLX store strings differently. Go to the ab.com knowledgebase and do a search on strings to get the technotes on the subject. I would consider creating a UDT that contains all seven strings as well (and since UDTs cannot be reconfigured online, you might make it hold a couple of extra strings just in case.) The ACII is probably best handled using a SINT array - which can also be a part of the UDT if you want. (Thats how I would do it). String handling in the CLX is best done in ST language instead of ladder. Edited 14 Oct 2005 by Alaric
