Overview of CX-Simulator
CX-Simulator enables you to realize SYSMAC CS/CJ series CPU Units in your
computer as a virtual PLC and operate (simulate) it equally as actual CPU Units.
Combination use of CX-Simulator and CX-Programmer enables you to verify ladder
program operation and cycle time in advance on a PC without an actual PLC.
Moreover, various debug functions of CX-Simulator make it possible to debug ladders,
which used to be impossible by using an actual PLC only.
Relationship between CX-Simulator and CX-Programmer
CX-Simulator creates a virtual PLC on a virtual network in your PC. If you use the
“Work Online Simulator“ function of CX-Programmer Ver.3.0 or greater versions,
CX-Simulator automatically starts up a virtual PLC of the current project’s device type to
open connection between CX-Programmer and the virtual PLC.
Before Installation
There are two setup types in CX-Simulator V1.3, but choose “1. For online with
CX-Programmer” if CX-Programmer has already been installed in your computer.
CX-Simulator is automatically installed in the directory where CX-Programmer is
installed.
Choose “2. For online with FinsGateway Applications” if you want to use a virtual PLC
for the debug of an application using the FinsGateway network.
Major Characteristics of CX-Simulator
Program execution, monitoring, debug without actual PLC
Monitoring of programs and IO memory present values is enabled. Moreover, normal
debugs such as force on/off, differential monitoring, data trace and online edit are
enabled from CX-Programmer. Also, any cyclic task can be started/stopped and
interrupt tasks can be started in simulation.
Cycle time check without actual PLC
It is possible to check estimated cycle time (current, minimum, maximum, and mean
values, servicing time *1) when the program is executed in an actual PLC in advance.
Program execution per step or scan, I/O brake condition settings
Debugs that cannot be realized in actual PLCs are provided.
Step Run: Executes a program per instruction
Scan Run: Executes a program per scan (cycle)
I/O Break Condition Settings: Aborts execution when the conditions set in I/O
memory are satisfied.
Designation of the start and break points
Debugs in connection with display devices and serial communications devices *1
Regarding the serial communications port of a PC as the communications port of a PLC,
it is possible to debug a program in combination with display devices or serial
communications devices (barcode reader, ID sensor, etc.).
Display of the send messages of serial communications and network
communications *1
It is possible to check the send messages issued by TXD instruction (communications
port output), SEND instruction (network send), and CMND instruction (command send).
It is useful for the debugs of serial communications and network communications.
*1: Yo u need to start CX-Simulator from the Windows [Start] menu and set a virtual PLC. See Chapter
5 and the operation manual of CX-Simulator for the detailed operations.

This chapter explains basic functions such as programming and comment entry of a simple
ladder by using CX-Programmer.
Here, a sample program “a program of car entry control by opening/closing shutters” is
created as an example. This program is used to explain how to use the debug functions o
CX-Simulator, which are mentioned after Chapter 3.

2-3 Creating Sample Program
The following is coding of a simple ladder program by using CX-Programmer.
This is a sample program of controlling car entry in a shed by opening/closing shutters.
When a car approaches, the shutters automatically open; and in two seconds after the
car passes the gate, the shutters close.
Upper limit SW (000001)
Lower limit SW (000002)
Normal rotation motor
(000500)
Reverse rotation motor
(000501)
rrival detection sensor (000000)
Operation Flow
(1) When a car enters, the arrival detection sensor (000000) is turned on.
(2) The normal rotation motor (000500) of the shutters is turned on.
(3) The shutters reach the upper limit in three seconds, the upper limit SW (000001) is
turned on, and the shutters open.
(4) When the car passes the gate, the arrival detection sensor (000000) is turned off.
(5) In two seconds, the reverse rotation motor (000501) is turned on.
(6) In three seconds, the shutters reach the lower limit, the lower limit SW (000002) is
turned on, and the shutters close.
See CX-Programmer Introduction Guide or the operation manual o
CX-Programmer for the detailed entry method of a ladder program.

This chapter explains how to operate CX-Programmer functions such as program transfer, PLC
mode change, cycle time check, and ladder program monitoring, when CX-Programmer is connected
to a CX-Simulator virtual PLC.
In addition, you can use CX-Programmer when connecting to a virtual PLC by the exactly same
operation as when connecting to an actual PLC. For detailed operations, see the operation manual
of CX-Pro
ammer.
