1-1-2 Software Configuration of CX-Simulator
The CX-Simulator consists of the Ladder Engine, which is composed of the
virtual CPU Unit and other units (default: only the Simulator Communications
Unit), the FinsGateway (version 2 or higher) Virtual Communications Unit, the
Debugger, and the Virtual External Input Tool.
Item Contents
A platform for CS/CJ-series PLC Emulation
Consists of multiple units.
Default: Consists of the CPU Unit and the Simulator Communications Unit.
CPU Unit A virtual unit corresponding to the actual CPU Unit, in-
cluding application programs (UM1), debugging pro-
grams (UM2), and I/O memory areas.
Ladder Engine
Simulator Communications
Unit
The CX-Simulator's own virtual and general-purpose
communications unit, corresponding to PLC's network
communications unit. Possible to communicate with the
CX-Programmer.
FinsGateway (ver-
sion 2 or higher)
Virtual Communi-
cations Unit
Connect Simulator Communications Unit in the Ladder Engine with FinsGateway ver-
sion 2 or higher. Two types are available: Virtual Controller Link Unit and Virtual
Ethernet Unit. The CX-Programmer also performs FINS communications with the Lad-
der Engine via the Virtual Communications Unit.
Debugger Controls the Ladder Engine and executes various CX-Simulator's own debugging
functions.
Debugging program (UM2) Possible to simulate I/O operation with a program in the
program area for debugging other than the area for ap-
plications (UM1).
For virtual external
I/O functions
Command log The log for CX-Programmer's operations (e.g. I/O mem-
ory change, Force set/reset) is saved in a file (Command
log file).
Possible to replay operation for the Ladder Engine using
the Data Replay Tool.
