Allen Bradley SLC500/Micrologix Strings

Postby pnogara » Tue Sep 04, 2012 2:12 am

HI SIelco Systemi

Is support to read and write to SLC/Micrologix string data files (eg ST10) planned?
It seems the only piece missing from what is otherwise very comprehensive support for Classic Allen Bradley PLCs.

From memory if a string element eg ST10:0 = "Hello" then
ST10:0.0 = ST10:0.LEN = 5 and
ST10:0.1-41 = ST10:0.DATA = <"He">, <"ll">, <"o"\00> (up to 82 chars)

And I am pretty sure A-B PLC 5 series is the same.
