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.
Function
Command log save 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.
Data Trace 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 Re-
play 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.
Multipoint Data Col- Possible to take in data from an actual PLC and to
lection Tool 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.
Data Replay 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
results can be saved as the Data Replay file.
I/O Condition The trigger conditions of I/O memory areas can be
Operation 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.
Program area for In addition to the program area for applications (UM1),
debugging (UM2) 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.
