Using the CX-Simulator with the following features can reduce man-days for
program debugging.
The CX-Simulator simulates operation of the SYSMAC CS/CJ/CP-series CPU
Unit. The operation of programs can be easily checked without an actual PLC
being connected. Using the CX-Simulator combined with the CX-Programmer
allows to develop/debug programs on a single computer.
Programs for the Virtual CPU Unit on the CX-Simulator can be seamlessly
debugged with the CX-Programmer that has been used. The powerful
monitoring functions (including those for a ladder diagram window and pre-
sent values) can be used as they used to be.
Furthermore, when CX-Programmer version 3.0 or higher is used with
CX-Simulator version 1.3, the CX-Simulator can be started and placed online
from the CX-Programmer.
An estimated cycle time for operation on the actual PLC can be obtained as a
virtual cycle time, which is different from an elapsed time on the computer. Use
it as a tentative time for operation on the actual PLC.
Adding dedicated debugging functions to the CX-Simulator enables more
detailed debugging than that of CX-Programmer + actual CS/CJ/CP-series
PLC.
A program can be executed in the unit of instruction. Peripheral servicing
during a stoppage by the address execution enables monitoring of program
being executed.
A program can be executed from any mnemonic code by designating a start
point. Setting multiple break points and break conditions depending on the I/O
memory status enables to pause a program at any point and on any conditions.
Scan Replay returns the program conditions to those just prior to the scan
started. The program can be replayed on the same conditions any times.
Displaying the number and the time of executions of each task will help solve
the bottleneck in executions, reducing the cycle time by re-division of the tasks.
Simulated startup of interrupt tasks at any timing enables to debug interrupt
processes.
In the CX-Simulator, debugging serial communications is possible by: (1) ac-
tual communications to an external serial communications device using a
