■ Example
The following tables show the examples of values set to the label name array (pLbLst) and data read to the device name array
(plDevLst). (For five labels to be read: Label1 to 5).
1.
Describe a target label name in a text file, and save it by specifying Unicode (UTF-16).
2.
Read the label name in binary format from the saved text file on a user program, and store the address of the label name
passed to the label name array (pLbLst) on the memory.
• Values set to the label name array (pLbLst)
