Caution
• RX for the upper word in the last station is occupied as the system area.
• When the TO instruction (or direct buffer memory specification) is executed for writing to an area without
assigned link points, writing is invalid. When the FROM instruction (or direct buffer memory specification) is
executed for reading from an area without assigned link points, the reading operation results in "0" being
read.
