CHAPTER 4
Reference
This chapter introduces the objects contained in the project workspace and discusses their associated commands
and features.
The following components, which are available either from the project hierarchy or from main menu, form part
of the CX-Server software.
♦
PLC Memory. Refer to the Chapter on PLC Memory Components of the CX-Server PLC Tools User
Manual;
♦ IO Table. Refer to the Chapter on IO Table Component of the CX-Server PLC Tools User Manual;
♦
PLC Settings. Refer to the Chapter on PLC Setup Component of the CX-Server PLC Tools User Manual;
♦
Data Trace/Time Chart Monitor. Refer to the Chapter on Data Trace/Time Chart Monitor Component of the
CX-Server PLC Tools User Manual;
♦
Error Log. Refer to the Chapter on PLC Error Component of the CX-Server PLC Tools User Manual;

PLCs and Projects
A project file contains one or more PLCs that are (potentially) connected to the computer. These PLCs do not
really have to be connected unless communications with them are to occur. A full description of the
communications possibilities for C-series PLCs, CV-series PLCs and CS/CJ/CP-series PLCs is provided in the
CX-Server PLC Tools User Manual .
The PLCs selected also affect which setup procedures need to be performed. For example, the CV-series and
CS/CJ-series require setting up the IO Table via the IO Table object in the project workspace and using the PLC
settings object to establish specific PLC characteristics.
Connection to the PLC requires the specification of the type of communications interface to be used to connect
to the PLC. Two methods of communication are available: serial communications and network communications.
Serial and network communications can be made using communication types although these are dependent upon
the type of communicating PLC.
Adding a PLC to the Project
CX-Programmer supports multiple PLC and multiple program support. When a project is initially configured, it
contains one PLC and one program. Additional PLCs and programs can be added.
Use the following procedure to add a PLC to a project.
1, 2, 3… 1. Select the Project object in the project workspace.
2. From the Insert menu select PLC or right click on the project folder and select Insert
PLC . The Change PLC dialog is displayed, part of the CX-Server application.
3. Set up the PLC as required. Refer to the CX-Server PLC Tools User Manual for further
information.
The project workspace is updated with a new PLC entry plus its associated global symbol table, IO Table,
Settings, Memory data and Program where applicable. An empty Ladder program is also displayed in the
Diagram Workspace.
The initial project, program and PLC settings are made whilst the PLC is offline. In order to test the program,
examine memory or monitor PLC operations, communications must first be established with the PLC. Refer to
Chapter - 4 Working On-line.
Changing a PLC in a Project
To change a PLC, double-click on the PLC object in the project workspace. The Change PLC dialog is
displayed. Refer to the
CX-Server PLC Tools User Manual for further information.
