3. POINTS OF CAUTION
■ GENERAL PRECAUTIONS
• Before you remove the module, turn off the power supply and input signal for safety.
■ ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the air, install the module inside proper housing with sufficient ventilation.
• Do not install the module where it is subjected to continuous vibration. Do not subject the module to physical impact.
• Environmental temperature must be within -5 to +60°C (23 to 140°F) with relative humidity within 30 to 90% RH in order to ensure adequate life span and operation.
• Be sure that the ventilation slits are not covered with cables, etc.
■ WIRING
• Wrong connection may damage the module.
• Do not connect cables to moving parts or pull them tightly.
• Do not install cables close to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises are present. Do not install them in the same duct.
■ AND ....
• The module is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.

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.

11.3. A/D CONVERSION
1) OUTPUT IN NORMAL CONDITIONS
Analog input signal (0 – 100%) from signal conditioners is converted proportionally into digital data, provided 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.

13. TROUBLESHOOTING
Basic troubleshooting methods are explained in this section.
For problems concerning the PLC CPU and Master Unit, consult users manuals for these units.
R1C-GH
13.1. L ERR. INDICATOR BLINKING
CHECK
Have you changed the station No. and/or baud rate settings during normal operation?
TROUBLESHOOTING
Return these settings to the state when the unit operated normally.
13.2. L ERR. INDICATOR ON
CHECK
Are the station No. and/or baud rate settings correct?
TROUBLESHOOTING
Set them correctly.
13.3. L RUN INDICATOR OFF
Consult the users manual for the Master Unit.
13.4. UNABLE TO READ/WRITE DIGITAL VALUES?
CHECK
Is the L RUN indicator OFF?
Is the L ERR. indicator blinking or ON?
Is the RUN indicator on the PLC CPU blinking or OFF?
Is the RUN indicator on the Master Unit OFF?
Are the RD/SD indicators on the Master Unit ON?
Are the wires for analog I/O properly connected to respective terminals? No wire breakdown?
Remove analog input wires and apply test voltage to the terminals (e.g. Use a dry cell). Try to read out digital value.
TROUBLESHOOTING
Refer to Section “13.3. L RUN INDICATOR OFF”.
Consult the users manual for the Master Unit.
Consult the users manual for the CPU.
Consult the users manual for the Master Unit.
Consult the users manual for the Master Unit.
Check these wires visually or check conductivity for each pair of wires.
If the digital value is read out normally, there are possibilities of noise interference via external wires. Check wiring and grounding.

14. CHECKING
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input: Check supply voltage across the terminals T6 – T7.
3) Input: Check that the input is within 0 – 100% of full-scale.
4) DIP SW setting: Check that all switches are set correctly.
15. ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered specifications, therefore you usually do not need any calibration.
16. MAINTENANCE
Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the module for at least 10 minutes. Apply 0%, 25%, 50%, 75% and 100% input signal. Check that the A/D conversion data for the respective input signal remains within accuracy described in the data sheet. When the A/D conversion data is out of tolerance, contact Factory or M-System’s local representative.
17. LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for protection against induced lightning surges.
Please contact M-System to choose appropriate models.
