For clarity, for anyone else trying to learn what I am trying to do I opened the settings in CX-Programmer and selected the Serial Port 1 Tab. I selected the standard communications settings (9600, 1, 7, 2, E), Start code set to Disable and Received bytes at 256 and set Mode to RS-232C. I used nicelabel to create a label using SATO fonts and selected the print to file option. This made me save it to a location. I then opened that file with notepad and copied the text. I created a rung in cx programmer with A392.13 and TXD instruction with S=D200 C=#0100 and N=&256
I opened the memory and chose d200 and clicked the "a" symbol to show values in text. I then pasted the previous values in that location. I then wired up a serial cable from the CP1W-CIF01 serial option board to the serial port of the S84-EX printer. I used grand technologies part number GTC99CC diagram to make my own male to male cable.
I loaded all the memory values and program to the PLC and closed W500.00 and the print job sent to the printer.
Now I have to figure how I can hook my computer directly to the PLC and get the print to file to automatically store that code in the D values. Or be able to modify the Dvalues real time through an HMI to change print quantity, etc.
