Memory card writing timing
If the write timing setting for Alarm Log, Data Log, and Operation Log data is set to Real Time, the data is stored in
the file output buffer once.
The writing timing from the file output buffer to the memory card is as follows.
• Within 3 minutes of an output event to the memory card.
• When the HG Special Relay LSM20 changes to 1.
• When switching to the System Menu.
• When downloading/uploading project data.
• When the Access Pause button is pressed.
●
Memory card access status
Models HG2G-5F, HG3G/4G, HG2F/3F/4F are equipped with a memory card interface and therefore have an Access
Lamp (LED).
The access lamp (LED) indicates the access status to the memory card. This status can also be read by monitoring HG
Special Relay LSM21.
The access lamp states and status descriptions of the HG Special Relay LSM21 are as follows.
Access lamp states
*1 HG2F/3F/4F only
In the following events, WindO/I-NV2 writes the data in the file output buffer to the memory card once,
and then moves on to the next process. This creates a processing delay which can cause WindO/I-NV2 to
raise a communication error when downloading or uploading a project file. If a communication error
occurs, try downloading/uploading the project file again.
• When data exists in the file output buffer
• When attempting to switch to the System Menu while reading/writing to the memory card.
• When downloading/uploading project data.
