Item Actual PLC CX-Simulator
Program mode Stop
Monitor mode and Run
mode
Continuous execution of scan
Minimum Cycle Time Logical cycle time: Substitute cycle time for
set value.
Actual cycle time: Regulate actual execution
time of one cycle on the computer.
Scan Run (only one scan)
Continuous Scan Run (one scan at regular
intervals)
Step Run (only one step)
Continuous Step Run (repeat address exe-
cution at regular intervals)

I/O memory ar-
eas
Available Available
I/O area alloca-
tion
Required PLC unit registration instead (No slot set-
ting)
I/O refresh Available None (Only for cycle time calculation. Con-
troller Link Unit, Ethernet Unit, and Serial
Communications Board/Unit performs virtual
operation.)
Peripheral ser-
vicing
Available None (Only for cycle time calculation. Con-
troller Link Unit, Ethernet Unit, and Serial
Communications Board/Unit performs virtual
operation.)
External input Available Generate virtual external input by one of the
followings.
• Overwrite I/O memory areas using the
debugging program.
• Issue FINS commands using the com-
mand log and the Data Replay Tool.
• Issue FINS commands using the data
trace file and the Data Replay Tool.
• Issue FINS commands using the data
replay file and the Data Replay Tool.
• Overwrite I/O memory areas using the
I/O Conditions Tool.
