Start/Stop Operation
This section describes operations to start and stop the Web server CPU module and to use the stop and reset inputs.
Start/Stop Schematic
Start/Stop Operation Using WindLDR
The Web server CPU module can be started and stopped using WindLDR run on a Windows PC connected to the Web
server CPU module. When the Start button is pressed in the menu bar shown below, start control special internal relay
M8000 is turned on to start the Web server CPU module. When the Stop button is pressed, M8000 is turned off to stop
the Web server CPU module.
1. Connect the PC to the Web server CPU module, start WindLDR, and power up the Web server CPU module. See
“Introduction” on page 4-1.
2. Check that a stop input is not designated using Configuration > Run/Stop Control > Stop and Reset Inputs. See "Stop
Input and Reset Input" of the basic volume (page 5-2).
Note: When a stop input is designated, the Web server CPU module cannot be started or stopped by turning start control special
internal relay M8000 on or off.
3. Select Online from the WindLDR menu bar.
The Online tab appears.
4. Click the Start button to start operation, then the start control special internal relay M8000 is turned on.
5. Click the Stop button to stop operation, then the start control special internal relay M8000 is turned off.
The PLC operation can also be started and stopped while WindLDR is in the monitor mode. Select Online > Monitor >
Monitor
and click the Start or Stop button.
Note: Special internal relay M8000 is a keep type internal relay and stores the status when power is turned off. M8000 retains its
previous status when power is turned on again. However, when the backup battery is dead, M8000 loses the stored status, and can be
turned on or off as programmed when the Web server CPU module is powered up. The selection is made in Configuration > Run/Stop
Control > Run/Stop Selection at Memory Backup Error. See "Run/Stop Selection at Memory Backup Error" of the basic volume (page
5-3).
The backup duration is approximately 30 days (typical) at 25°C after the backup battery is fully charged.
• Make sure of safety before starting and stopping the Web server CPU module. Incorrect operation on the
Web server CPU module may cause machine damage or accidents.
Caution
The start/stop circuit of the Web server CPU module
consists of three blocks; power supply, M8000 (start
control special internal relay), and stop/reset inputs.
Each block can be used to start and stop the Web
server CPU module while the other two blocks are set
to run the Web server CPU module.
