Designed to facilitate seamless industrial Ethernet-based communications across mixed-manufacturer control systems, the Omron CJ1W-FLN22 functions as a high-reliability FL-net interface module within the CJ-series automation architecture. This module operates as a dedicated CPU Bus Unit, enabling deterministic data exchange and real-time inter-controller links between Omron systems and third-party PLCs or CNCs conforming to the FL-net (OPCN-2) standard. Operating on an efficient 5 VDC internal bus supply, this module combines low power consumption with robust industrial-grade noise isolation to ensure stable, non-stop network performance in demanding factory automation systems.
| Parameter | Specification |
|---|---|
| Manufacturer | Omron Corporation |
| Model Number | CJ1W-FLN22 |
| Unit Classification | CJ-series CPU Bus Unit |
| Media Access Protocol | CSMA/CD |
| Transmission Path / Topology | Star Topology |
| Current Consumption | 370 mA max. at 5 VDC |
| Shock Resistance | Conforms to JIS C0041 (147 m/s2, three times each in X, Y, and Z axes) |
| Operating Humidity | 10% to 90% RH (non-condensing) |
| Operating Atmosphere | Must be free from corrosive gases |
| Dimensions (W x H x D) | 31 mm x 90 mm x 65 mm |
| Net Unit Weight | 0.1 kg |
| Shipping Weight (Calculated) | 1.5 kg (inclusive of packaging materials) |
| Interface / Port | Description & Function |
|---|---|
| RJ45 Ethernet Connector | Standard 10Base-T / 100Base-TX physical interface connection point for FL-net networking. |
| Front-Panel LEDs | Indicates network status, RUN mode, and active transmission errors. |
| Rotary Switches | Local hardware address configuration (Node ID assignment). |
This unit directly replaces older CJ1W-FLN02 legacy modules. While backward compatible in basic cyclic transmission modes, users must verify that the corresponding CPU rack firmware supports the advanced routing capabilities of the FLN22. Check unit revision letters on the side panel label before commissioning parallel networking topologies.
Do not operate this CPU Bus Unit adjacent to high-current output cards or AC contactors. Radiated EM noise can disrupt packet delivery cycles over the CSMA/CD layer, leading to network timeouts. Ensure the cabinet temperature remains below 55 degC, as thermal saturation in sealed enclosures can cause intermittent communication drops.
Always use Category 5e (or higher) double-shielded twisted-pair (STP) cabling with metal-hooded RJ45 plugs. Ground the cable shield at the switch side only, or follow the system-wide equipotential bonding guidelines to prevent ground loop currents from flowing through the communication port.
CRITICAL WARNING:
Disconnect all power sources to the PLC rack and output modules before mounting or removing the CPU Bus Unit. Failure to completely isolate power can result in terminal damage, backplane failure, or unexpected system startup.
Align the upper and lower locking catches of the module with the slots on the CJ-series backplane.
Carefully press the module straight onto the bus connector until the locking levers click firmly into place.
Configure the hardware node switch on the front panel to the desired address, avoiding overlapping node configurations.
Connect the shielded RJ45 Ethernet cable, verifying that the connector latch locks securely to prevent loose-fit faults.
