If the “Storage Space Insufficient” message pops up on the
HMI screen (Window number 8 in EBPro), it is likely caused by not having a USB
flash drive or SD card connected to the HMI when the Event/Alarm log or the
Data Sampling Object is configured to save data to one of these memory devices.

When the message pops up, one of the Bit Lamps will be
illuminated corresponding to either HMI memory, SD card, or USB disk. Connect
the appropriate memory device and the message will no longer pop up.

Note: If the “HMI Memory” lamp lights, then the Event/Alarm
log and/or Data Sampling Object is configured to save data to HMI memory
without the Preservation Limit option enabled and the HMI memory is full. See “How
to clear HMI memory.”
