Communication using ASCII

Delete rung 1 and 2 you should only have
XIC B3:2/1 BST AWA 0 ST10:1 R6:0 0 NXB XIC R6:0/DN OTU B3:2/1 BND

now type in N01123456 into ST10:1
then toggle B3:2/1

Ok, it's done. Data table for ST10:1 says LEN=9, string text is N01123456.

What happened when you toggled the B3:2/1?

What happened when you toggled the B3:2/1?

Nothing happened at the display, if that's what you're asking, it's still showing "0".

try ron's idea and see what happens.

check you email

I tried Rons' idea and connected it to hyperterminal and nothing is displaying on the screen. I had to shut down Linx in order to use com1. I will check my email now.

then maybe you don't have HyperTerminal set up correctly ... the code I posted works fine for me – see the HyperTerminal display at the right side of the picture ... (note that my Channel 0 was set for SYSTEM mode during the test) ...

I had to shut down Linx in order to use com1.

why? ... are you using the COM1 port on your computer for RSLogix500? ...

when we talked earlier I thought that you said that you have a SEPARATE computer that you can run HyperTerminal on for testing purposes ...

And, after ruling out everything else, try swapping RX and TX on one end of your cable.

Ok, it is working like a champ now. I kind of figured it had to do with the display itself, and it was. Format MUST look like this: NxxIxxd6,d5,d4,d3,d2,d1, <cr>, or it will not work. Thanks guy's, I could never have done this without your support.

Nxx= display address
Ixx= user input function (if not used you must still enter a "00".
d-6 thru d-1= ASCII data
<cr>

Hope this helps someone else in the future.

I was wrong about shutting down Linx. It is using Com5, the hyperterminal is using Com1.
When I load the program attached it times-down and every 30 seconds it displays another "30". So my screen looks like this:
0
30
30
30
30
30.....

attach your program and we'll check it - or just double-check the addresses of the TIMERS yourself ... sounds like you've got a typographical error ... the number should increment by ONE each second ...
