TI555 texas instruments PLC ASCII string help

I need help writing code that sends one real # out of a serial port (RS232)in form of an ASCII string.

The processor is a Siemens (Texas Instruments) 555-1105
The serial port module in the rack is a 505-2571
The software is either TISOFT or Workshop.

edit

wow. nm, i should read. Ok, a 2571 card.

So, short answer, you need to set the module dip switch for the port on the card you are using to PLC select.
Then, create both a "create connection command" block and a "Write command" block. I often set most of these using a special function set to cyclical w/ a 5min timer.
ftp://ftp.controltechnology.com/public/Pubs/PRODUCTS/257X/06200182.pdf pages 18-20 for the format of those blocks.
But read the whole manual and note that you'll be using the GAS protocol manager.

Thanks, this is the info I've been looking for!
