♦
If tags are used, they must have the data types and names as the corresponding network variable in
the host (PLC). Therefore, we recommend that you copy tags from the CX-Programmer’s symbol
table.
♦
STRING variables and array variables cannot be created with the CX-Designer.
Copying from the Symbol Table of the CX-Programmer
Use the following procedure to copy tags from the CX-Programmer’s symbol tables.
1. Select the network variable to be reused in the CX-Programmer’s symbol table.
2. Drag and drop the tag to the CX-Designer’s symbol table to copy it.
