After completing static debugging, it is necessary to debug a program as-
suming external inputs such as a sensor in the actual running.
In the conventional debugging, it used to be necessary to give actual inputs
from switches or tools assuming sensor inputs, motor outputs, or others and to
visually check the outputs, requiring a lot of man-days.
The CX-Simulator is equipped with such functions as to automate creating
virtual external inputs and the data for executing/monitoring debugging pat-
terns and to save its workload.

The CX-Simulator saves operation history of the
CX-Programmer as FINS commands. Executing the
saved data can be repeated using the Data Replay
Tool.
The actual PLC's data trace data saved by the
CX-Programmer's data tracing or time chart monitoring
can be input to the CX-Simulator using the Data Replay
Tool. Also, long-term data that can not be saved by the
CX-Programmer's data tracing can be saved using
Data Trace Recording Tool.
Possible to take in data from an actual PLC and to give
the data as input data to the CX-Simulator using the
Data Replay Tool. Unlike Data Trace, every-cycle data
can not be read. However, more than 50 words of data
can be read.
Each data of the command log (.flg), the Data Trace file
(.cdt), and Data Replay file (.cvs) can be input to the
CX-Simulator as virtual external inputs. Also, the re-
sults can be saved as the Data Replay file.
The trigger conditions of I/O memory areas can be
described in logic expressions and the value can be
given to the I/O memory area as virtual external inputs
when a set time elapses after the expressions hold.
Multiple expressions can be processed simultane-
ously.
In addition to the program area for applications (UM1),
the CX-Simulator provides the program area where the
ladder program, sharing the I/O memory area with
UM1, for creating virtual external inputs is executed
(UM2). Virtual external inputs can be created in the
ladder program.
