Setting initial device values

This section describes the settings of initial device values.
Setting procedure
The procedure for using initial device values is as follows.
1.
First, the user must create an initial device value file. To set initial values to a local device, create an initial device value
file with the same name as the program which sets these values, and specify the range of the values. To set initial values
to a global device, create an initial device value file (with any name) which sets these initial values, and specify the range
of the values.
2.
On the device memory, set up initial device value data within the range specified in the initial device value file.
( GX Works3 Operating Manual)
3.
In the "Device Memory Register Diversion", select the device memory which was set up in Step 2. Setting "Device
Memory Register Diversion" enables data set up on the device memory to be used as initial device values for the device
which is specified in the initial device value file.

4.
Configure CPU parameters. ( Page 519 Initial value setting)
5.
Write the set initial device value file and the CPU parameters to the CPU module.
( GX Works3 Operating Manual)
6.
The data in the specified initial device value file is automatically set to the specified device or buffer memory of the
intelligent function module when the CPU module is powered off and on, reset, or the status changes from STOP to
RUN.

Item Description
Target Memory Sets the storage memory for the initial device value file, initial
global label value file, and initial local label value file.
Setting of Device Initial Value Selects whether or not to use initial device values.
Use Or Not
Global Device Initial Value Sets the name of the initial global device value file.
File Name
*1 If nothing is specified, initial global device values are not applied.
*2 If "Target Memory" is set to "Memory card", boot a target file from the SD memory card with the boot operation. ( Page 225 BOOT
OPERATION)
*3 If "Setting of Device Initial Value Use Or Not" is set to "Use" and the specified initial global device value file does not exist, an error
occurs. If the other file (initial local device value file, initial global label value file, or initial local label value file) does not exist, an initial
value is not applied, but an error does not occur.
