(e) Monitor data pointer storage area (Address: according to monitor buffer head
address setting (Default: 2600H/3300H))
• The oldest data position of the monitor data area is stored using the offset value from the head address of
the monitor data area.
• 0 to (monitor buffer size specification (Default: 0D00H) -3): oldest data position
• When the monitoring data exceeds the monitor buffer size, the new data is written over the oldest data. (Ring
buffer type) The oldest data position of the monitor data area can be confirmed from this area.
"2611H" becomes the oldest data when "000FH" is the monitor data pointer using "2602H" as the head
address of the monitor data area.
(f) Monitor data size area (Address: according to the monitor buffer head address
setting (Default: 2601H/3301H))
The number of monitor data stored in the monitor data area is stored.
0 to (monitor buffer size specification (Default: 0D00H) -2): Number of monitor data
