Operation
When the CC-Link is installed, some operation differs from the other Fieldbus I/O options. This section describes these differences.
Remote I/O
Remote input (RX) and remote output (RY) indicates ON/OFF information. Remote data is bit data and the FROM/TO command is executed per 16 bits (1 word).
"n" in the following tables is address configured as a master station with the station configure.

*1: Remote control inputs and outputs are not allocated to fieldbus slave I/O by default.
To allocate remote control inputs and outputs to fieldbus I/O, refer to following section.
Setting Remote Control Input and Output
*2: When initialization of the CC-Link board is completed at the Controller turn-on, Remote Ready flag (in this example, [RX(n+D)B]) turns ON.
I/O assignment of Remote Ready cannot be changed or disabled (NA).

The number of stations, remote I/O range, and remote register range depend on the input / output size.

| Input / Output Byte Configuration (RC+) | Occupied Stations | Remote I/O (Bytes) | Remote Register (Bytes) |
|---|---|---|---|
| 0 < x = < 4 | 1 | S | 0 |
| 4 < x = < 12 | 4 | x - 4 | |
| 12 < x = < 24 | 2 | 8 | x - 8 |

KEY POINTS
When the input and output size of RC+ is set to 32 bytes (default value), number of occupied station will be 3, Remote I/O will be 12 bytes, Remote Register will be 20 bytes (10 words), and system reserved area will be 4 bytes.
When the input and output size is set to 36 bytes, number of occupied station will be 3, Remote I/O will be 12 bytes, Remote Register will be 24 bytes (12 words), and system reserved area will be 0 bytes.
In Version 2.00, there is no system reserved area.

The number of occupied stations is the ones on the CC-Link network. Set this number to the master station.
Remote I/O is ON/OFF information.
Remote I/O data is bit data and the FROM/TO commands are executed in units of 16 bits. Remote register is in numeric data.
