2) Details for the buffer memory allocation related to remote outputs (RY) when the expanded cyclic
transmission is set
The table below shows details for the buffer memory allocation related to remote outputs (RY)
when the expanded cyclic transmission is set.
Caution
• RY 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, 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.
