7.1 Buffer memory list
The table below provides a brief description and reference information for the 64CCL buffer memory.
→ For details on the buffer memory, refer to Section 7.2.
R/W : Read/write is possible
R : Read only
*1. Read/write is only possible when the expanded cyclic transmission is set to "single."
*2. When writing to an area without assigned link points, writing is invalid. When reading from an area
without assigned link points, the reading operation results in "0" being read.
*3. Only a value of "0" can be written and accepted.
