Operation Log Function
When the Set limit on files check box is selected, note the following points.
• If the number of data files saved on the external memory device increases, it may take some time for
the data output processing, or the output of the next data may not be processed normally.
• When displaying pictures saved on the external memory device and processing the output of data both
occur simultaneously, the pictures may not be displayed.
• When parts that blink overlap pictures saved to the external memory device, the blinking period may
slow down when data output processing occurs.
• The following single-byte characters cannot be used in the file name configured by File Name or
Specify File Name by Value of Device Address.
" * / : ; < > ? \ |
• File names that exceed the limits in Specify File Name by Value of Device Address and file names
configured with characters that cannot be used are as follows.
- When the text of the file name exceeds the maximum number of device addresses (no NULL), the text
stored in device addresses up to the maximum number of device addresses from the start is
configured.
- When a character that cannot be used is set, the text is up to that character.
- When the first character is a character that cannot be used, the text is that set for File Name.
• The operation when the Set limit on files check box is selected is as follows.
- The files are output up to the set limit, and then for additional files, the new files are saved by
discarding the old files in order of the oldest first.
- If the number of files saved on the external memory device already exceeds the limit when operation
starts, the number of files at that time is the limit. From there the data is discarded in order from the
oldest data and replaced with new data with each file output.
• The following operations are as follows if the Realtime Output check box is selected.
- Even if the data is outputted forcibly, the real time output period (3 minute interval) is not reset.
- While data is being output with the real time output function, the file is not output when the value of
the Realtime Output device address is 1.
- Even when output has finished, the value of device address does not automatically change to 0.
• The function to record data operates when Operation Log data is being saved to the external memory
device.
• The batch output or real time output status of the Operation Log data can be checked with the value of
HMI Special Internal Relay LSM37. When the data starts to be written to the external memory device, the
value of device is 1. When writing is complete, the value is 0.
• The methods to erase Operation Log files saved on the external memory device are as follows.
- To erase files during operation using parts, on the External Memory Device tab in the Project
Settings dialog box, select the Remove Files stored in External Memory Device check box and the
All Operation Log data check box, and then configure the trigger device address. Assign that trigger
device address to a part.
- To erase files with WindO/I-NV4, click Clear on the Online tab, and then click Stored Data in
External Memory Device to open the Clear Data dialog box. Select the Operation Log Data check
box and click OK.
- To erase files on the HG5G/4G/3G/2G-V, HG4G/3G and HG2G-5F, go to the System Mode - File Manager.
In the File Manager, select the files to be deleted by pressing DEL.
