range.
• Tracking cannot be set for link direct devices.
• Do not set tracking for the link special relay areas (SB0020 to SB01FF), which are turned on/off by the system, or the link
special register areas (SW0020 to SW01FF), where data is stored by the system.
For details on tracking, refer to the following.
