11. DATA LIST

11.1. REMOTE I/O

For CC-Link Ver.1.10, the R1C occupies 4 nodes according to the number of I/O channels, for CC-Link
Ver.2.00, it occupies 1 node. Regardless of the number of nodes, for CC-Link Ver.1.10, 32 bits are assigned
to each of input and output for sending to/receiving from the Master Unit, for CC-Link Ver.2.00, 64 bits are
assigned. One (1) bit among RXxB* is used as remote device (R1C) READY signal, turned ON when the
R1C is in normal operation.
• CC-Link Ver.1.10
*x = (Station No. × 2 – 1) H
[example] Station No. = 9
9 × 2 – 1 = 17 ➡ 11H
READY signal is input at RX11B.
• CC-Link Ver.2.00
*x = (Station No. × 4 – 1) H
[example] Station No. = 9
9 × 4 – 1 = 35 ➡ 23H
READY signal is input at RX23B.

11.2. ASSIGNING REMOTE REGISTERS

The R1C does not use the remote registers for the direction from the Master to Remote (RWwn to RWwn+15).
The table below shows the data assignment of those for the direction from the Remote to Master.
DIRECTION ADDRESS
RWrn + 0
RWrn + 1
RWrn + 2
RWrn + 3
RWrn + 4
RWrn + 5
RWrn + 6
R1C
RWrn + 7

RWrn + 8
Master
RWrn + 9
RWrn + 10
RWrn + 11
RWrn + 12
RWrn + 13
RWrn + 14
RWrn + 15

11.3. A/D CONVERSION

1) OUTPUT IN NORMAL CONDITIONS
Analog input signal (0 – 100%) from signal conditioners is converted proportionally into digital data, pro-
vided to the Master Unit.
2) OUTPUT IN AN ABNORMALITY
When an abnormality such like CPU error, STOP, time-out occurs at the PLC, the output signal of the R1C
is maintained as HOLD (no clearing output signal, keeping the value just before the abnormality).
When the PLC recovers to normal operation and the R1C receives new data, the output restarts changing.
