Writing Data To The Module - Mitsubishi Electric MELSEC-L Series LD40PD01 User Manual

Writing data to the module

Write the hardware logic to the execution memory of the flexible high-speed I/O control module.
The execution memory and the flash ROM can be selected as the write destination of the data. Select only the execution
memory or both the execution memory and the flash ROM as the write destination.
Because the hardware logic written into the flash ROM is read to the execution memory at power-on, a control can be started
without re-setting. However, the number of writable times to a flash ROM is 10000 times. Thus, using different write
destinations as shown in the following examples is recommended.
• When the adjustment is repeated with changing the settings, select "Write to Module (execution memory)".
• After the adjustment is completed, select "Write to Module (execution + flash ROM)".
Users can set a password for the hardware logic by setting "Enable" in the [Security] menu of [Project]. For the hardware logic
with a password, users are required to input the password for reading the hardware logic from the module.
Writing data
The following describes how to write data.
1.
Select a writing method depending on a selected write destination.
[Online]  [Write to Module (execution memory)] or [Write to Module (execution + flash ROM)]
When "Write to Module (execution + flash ROM)" has been selected and the number of writes to flash ROM exceeds 10000
times, the error window is displayed. Data can be written to the module even in such situation. However, the data written in the
flash ROM is not guaranteed.
2.
When the following conditions are satisfied, set a password.
• "Enable" has been set in the [Security] menu of [Project].
• [Write to Module (execution + flash ROM)] has been selected.
• If data writing is executed while the hardware logic control is operating, the hardware logic control will stop
and the data will be written to the module. After the data writing is completed, the hardware logic control
restarts.
• If data writing is executed while the hardware logic control has stopped, the stop status of the hardware
logic control will continue.
