Buffer Memory
10.14 [BFM#16896 to #16927] Ver. 2 Compatible Remote Output (RY)
Used when the remote net ver. 2 mode or remote net additional mode is selected.
The output status from remote I/O stations, remote device stations and intelligent device stations are stored.
When 1 station is occupied, 2, 4 or 8 words are used. The number of used points changes depending on the
expanded cyclic setting and the number of occupied stations.
In addition, the ver. 2 compatible remote output (RY) is assigned to the following buffer memories according
to slave station offset and size information (RY offset, RY size).
→ For details on the expanded cyclic setting and number of occupied stations, refer to Section 2.3.
→ For details on the slave station offset and size information, refer to Section 10.11.
Example
Caution
• 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.
• The last two bits cannot be used in the communication between the master and intelligent device stations.
• The upper 16bits (1 word) in the last station of remote stations and intelligent device stations is occupied
as a system area. For details, refer to the each unit's manuals.
