Module Operation - Mitsubishi Electric MELSEC-L Series LD40PD01 User Manual

Module operation

The hardware logic control can be started or stopped with the configuration tool.
Start or stop the hardware logic control under the following situations.
Operation
Starting the hardware logic control
Stopping the hardware logic control
How to start or stop the hardware logic control
The following describes how to start or stop the hardware logic control.
[Online]  [Module operation]  [Hardware logic control start] or [Hardware logic control stop]
This operation can be performed during monitor execution. For details on the monitor, refer to the following.
Page 93 Monitor
When the hardware logic control is stopped, the count value of the counter timer block is reset. To stop the
count operation without resetting the count value, turn off the count enable of the counter timer block.
Checking the operating status of the hardware logic control
The operating status of the hardware logic control can be checked in the toolbar during monitor execution.
Hardware logic control status
During hardware logic control
During hardware logic control stop
When the hardware logic control is started or stopped from the configuration tool, Hardware logic control flag (X4) turns on or
off. Thus, users can check the operating status of the hardware logic control by monitoring the status of Hardware logic
control flag (X4) in GX Works2.
For details on Hardware logic control flag (X4), refer to the following.

Relations of operations with output signals and window operations
The hardware logic control can be started or stopped with the configuration tool or output signals (Y4, Y5). The (start or stop)
status of the hardware logic control changes depending on the last operation performed.
• When [Hardware logic control start] is selected with Hardware logic control stop request (Y5) on, the hardware logic control
is started.
• When [Hardware logic control stop] is selected with Hardware logic control start request (Y4) on, the hardware logic control
is stopped.
For details on Hardware logic control start request (Y4) and Hardware logic control stop request (Y5), refer to the following.

Situation
• Use this operation after the power is turned on. The hardware logic control is stopped after the power-on. Check
the safety and select [Hardware logic control start] to start the control.
• Use this operation after the completion of the simulation. The hardware logic control is stopped after the completion
of the simulation. Select [Hardware logic control start] to start the control again.
Use this operation to check the module and system status. Select [Hardware logic control stop] to stop the control.
When checking the module and system status, stop the hardware logic control for safety.
Button status Remarks
The "Hardware logic control stop" button can be
pressed during the hardware logic control.
The "Hardware logic control start" button can be
pressed during the hardware logic control stop.
