4-1 Debugging Using the CX-Programmer
Debugging using the CX-Programmer can be performed in the same opera-
tion as the CS/CJ-series PLC because the CX-Simulator implements equiva-
lent functions as the CS/CJ-series PLC.
This section shows the differences with the actual CS/CJ-series PLC and no-
tices when operating the CX-Simulator from the CX-Programmer.
Operation of the CX-Programmer Differences/Notices
Transfer/compare a program. Same
Monitoring Monitoring is possible even during a scan when in Step
Run.
Force Set/Reset and Set/Reset
Bits
Force Set/Reset and Set/Reset Bits are possible even
during a scan when in Step Run.
Change the present value of a
word.
Changing the present value of a word is possible even
during a scan when in Step Run.
Change the set value of the
Timer/Counter.
Changing the set value of the Timer/Counter is possible
even during a scan when in Step Run.
Detect a rising/falling edge (differ-
ential monitor)
Differential monitor is possible even during a scan when in
Step Run.
Online Editing Online Editing is possible even during Step Run and scan.
Online Editing during Step Run (including Continuous Step
Run) will return the program control to the head (when
Online Editing enabled for Scan Replay/ Step Run).
Data Trace/Time Chart Monitoring The time axis (the horizontal axis) of the time chart moni-
toring shows the different time with that of the CX-
Simulator operation when in the virtual cycle time mode or
pausing.
Cycle Time Display Setting from the CX-Simulator allows to display the cycle
time in the virtual cycle time or computer cycle time.
Occurring Error and Error History
Display
Same
Register/Set a Password Same
Read/Set Clock Same (The day of the week is automatically corrected
following the calendar in the CX-Simulator.)
Release an access right Same
Note When operating the Ladder Engine only from the CX-Programmer and not
from the CX-Simulator Debug Console (in the Monitor mode and in Continu-
ous Run), the same operation as when the CS/CJ-series CPU Unit is con-
nected to the CX-Programmer can be performed.
