Chapter 8: Cyclic Transfer
Notes on the common memory areas
The common memory areas (area 1 and 2) can also be set using the following procedures.
1.There is no need to allocate sequential node numbers. [Example]
| Node | Node | Node |
| 2 | 4 | 7 |
| Node 2 | Node 2 | Node 2 |
Area 1 | Node 4 | Node 4 | Node 4 |
| Node 7 | Node 7 | Node 7 |
2. There is no need to assign data memory areas in node number order.
| [Example] | Node | Node | Node |
|
|
| Node | |||
|
| 1 | 2 | 3 | 4 |
|
| Node 1 | Node 1 | Node 1 | Node 1 |
| Area 1 | Node 4 | Node 4 | Node 4 | Node 4 |
| Node 3 | Node 3 | Node 3 | Node 3 | |

3. There is no need for continuous data memory areas.
[Example] |
|
|
|
| Node | Node | Node |
| 1 | 2 | 3 |
| Node 1 | Node 1 | Node 1 |
Area 1 | Node 2 | Node 2 | Node 2 |
| Node 3 | Node 3 | Node 3 |
