The symbol table allows these names to be entered and edited directly. Each symbol name
must be unique. Use the following procedure to activate the symbol tables.
1, 2, 3…
1. Double-click on the symbol table object beneath the PLC in the project workspace. The
global (i.e. PLC’s) symbol table is displayed containing global symbols.
Double-click on the symbol table object beneath a program in the project. The program’s local
symbol table is displayed.
Using CX-Programmer
This chapter contains an example tutorial and also describes basic procedures that should be
considered
before performing any programming task on the computer and preparing ladder
programs with CX-Programmer, and how to use the various tools to improve productivity.
CX-Programmer offers many methods of working with its tools: in general, instructions are
given for using the toolbar icon in the first instance.
The following tutorial has been based on a CS1H PLC. The choice of PLC made here affects a number of other
parameters that may need to be set up. For example, the CV-series requires setting up the IO table, and using the
Settings object in the Project hierarchy to establish specific PLC characteristics.
When planning a PLC programming project, various items need to be considered and set up within CX-
Programmer before beginning to lay down program instructions. For example, it is important for CX-
Programmer to know the model and configuration of the PLC to be programmed, so that it can establish the
correct program checking and communications for that PLC. Programming should be targeted at the PLC that is
to be used. It is possible to change the PLC type at any time - the program(s) are then converted. However, since
the conversion may not be perfect, it is best to set the correct PLC type at the beginning.
Before programming, it is recommended that a checklist of the important program aspects be
constructed, including its structure and PLC parameters. To start a new project in CX-
Programmer, follow these steps in addition to the basic procedure outlined in your PLC
programming manual:
