Adding an RS-232 Insert
When you are using an external device (such as a scale, scanner, or PLC) to
send text to your controller, you need RS-232 inserts. When printing, RS-232
inserts will automatically update with the data sent from the external
device. (Make sure your external device is connected to the controller. (See
“Optional External Devices” on page 3-26.)
When an external device sends RS-232 commands and data to the
controller, the controller places the RS-232 data into a buffer. For example, a
shoe manufacturer may have a packaging line with an external device
sending 22 characters where the first 19 are the name of a shoe (Athletes
Cross Trnr, Elite Runner, Wimbledon Tennis, etc.) and the last three are the
color (Blu, Brn, Red, etc.). With some sample data, the shoe manufacturer’s
buffer might appear as follows:
When you create RS-232 inserts, you specify which characters of the buffer
you want in each field. You therefore specify a buffer starting point (or field
offset), and you specify the total number of characters to use. For example,
if you want to print the type of shoe in one RS-232 insert and the color in
another, the RS-232 inserts would be defined as follows:
A message can contain up to eight user inserts. For more information on
RS-232 inserts, see Appendix C.
1) At the message screen, place the cursor in the message where the
element will be added.
2) Select a font. (See Page 4-26.)
3) Press Options. A menu is displayed.
