Can U90 do string within string, even in a roundabout way?

[Ausman]

HI all, I have a small job on that I am sure I can do with a 130, but the cheaper option would be a low level jazz as it only needs 232 comms and a few outputs.  The issue is that I need to find a string within a string that will come in now and then on the serial port.  The main string that routinely comes in occasionally has a different header along with a particular sub-string that can be anywhere near the end of the entire string, and the overall string length always varies according to other inclusions.  If both the header and the sub-string are there, the output actions will be triggered.  Although I've worked with U90 for ages and don't think this is possible, just asking if anyone has found a way to do it?  Or if it is blindingly obvious somewhere and I have simply missed it?!

cheers, Aus

Maybe Samba with Protocol FB is the cheapest solution. But problem with testing - only one PORT present in Samba.
I used isolated com card installed in Samba  for that purpose.

I'd stick with a Vision Aus, working with strings is just easier inside it, a SM35 would also be a good thing to look at as it's has the native serial port. and you can add a second one or put an ethernet card in if you don't want to use the same port for the program and programming the unit.

Thanks guys for the input, I'll go down the Vision path.
