Applicable range of initial device value files
The applicable range of initial device value files is as follows.
Target device
Applicable range
Global device
Initial device values set up in the initial value file of the global device are used.
Buffer memory
Local device
Initial device values set up in the initial value file of the local device (Program Name.DID) are used.
File register
• When "Use File Register of Each Program" is set, initial device values set up in the initial value file of the local device (Program
Name.DID) are used. If there is a program which doesn't have its file register (a file register with the same name as the program),
it is not assumed as an error but the initial device values are not used.
• When a common file register is used across all programs, initial device values set up in the initial value file of the global device
are used.
Number of initial device value settings and maximum range of one range
Up to 1000 ranges can be set in one initial device value file. Up to 8000 data points can be set in one range.
Setting initial label values
This section describes the settings of initial label values. For labels assigned to a device, the initial value setting follows the
initial device value.
Setting procedure
The procedure for using initial label values is as follows.
1.
Set up initial label values using a global label and local label.
2.
Configure CPU parameters ( Page 398 Initial value setting).
3.
The CPU parameters, programs, initial global label value file, and initial local label value file are written to the CPU
module.
( GX Works3 Operating Manual)
4.
The data in the specified initial global label value file and initial local label value file is automatically set to the specified
label when the CPU module is powered off and on, reset, or the status changes from STOP to RUN.
