■Format of a save date and time folder name
The name of a save date and time folder is a date and time when saving project data starts in a recorder module/camera
recorder module.
The time (local time) in a CPU module is used for the date and time.
Output format
YYYYMMDDhhmmssms
YYYYMMDDhhmmssmsDST
*1 'DST' is added to the end of the date and time for the daylight saving time.
Ex.
When the date and time is 1:00:00:000 milliseconds on April 1st, 2021, the folder name is as follows:
Standard time: 20210401010000000
Daylight saving time: 20210401010000000DST
Precautions
The file (UpDateTime.bin) stored immediately under a save date and time folder is a system management file. Do not edit or
delete it.
■Project data saving completion file
When saving project data to a file server is completed, the saving completion file is created as follows:
File name
Same name as a save date and time
folder
Using saved project data
When specifying an SD memory card as a save destination, saved project data can be used to play a recording file by
selecting the checkbox of "Read Project Data" in the "Recording File Reading" screen of GX Works3 and reading it from a
recorder module/camera recorder module at the same time as the recording file.
When specifying a file server as a save destination, saved project data is opened at the same time when playing a recording
file in the file server on the offline monitor of GX Works3, and can be used to play the recording file.
To read or open saved project data, GX Works3 supporting this function is required. (Page 307 Added and Changed
