(6) Precautions for the use of device initial values

6.26 Device Initial Value
- 163
(a) When device initial value data and latch range data are overlapped
In cases where both device initial value data and latch range data are overlapped,
the device initial value data takes priority.
Hence, the latch range data are also changed to the device initial value data when
the power supply is switched OFF and then ON.
(b) Disabling the device initial value from being set in a device area at the time
of STOP
RUN
The device initial value data are reflected at the time of STOP
device initial value function.
To disable the device initial value data from being reflected at the time of STOP
RUN in a certain device area (data that are set at power supply OFF
are changed by a program), use the MOV instruction or similar one in the main
routine program so that the initial values will be set to the specified devices only.
Use the TO instruction to write data to the buffer memory of the intelligent function
module.
(c) Devices that require module synchronization setting
When specifying the following devices in the device initial value range setting,
make "Module synchronization setting" in the PLC system setting of the PLC
parameter dialog box.
If the module synchronization setting is not made, the device initial values may not
be set to the target module properly.
• Intelligent function module device (U\G)
• Link direct device (J\W, J\SW)
Remark
Refer to the following manual for the device initial value range setting, the device
initial value data setting operation, and the operation for writing the device initial
values to the CPU module.
