F3LR01-0N FA-M3 Fiber-optic FA-bus Module | Yokogawa

Yokogawa F3LR01-0N FA-M3 Fiber-optic FA-bus Module

Configured for distributed system expansion and remote I/O unit interconnection in FA-M3 PLC networks, the Yokogawa F3LR01-0N (F3LR01 Fiber-optic FA-bus Module) provides direct physical/electrical execution. It establishes high-speed communication lines between main units and sub-units, allowing I/O refresh cycles to operate within ladder programming limits without requiring dedicated software environment configuration.

Hardware Specifications

Channel-to-Channel Isolation and Optical Noise Immunity

The interface utilizes dedicated optical transceivers to achieve complete electrical and channel-to-channel isolation between distributed chassis nodes. By converting electrical backplane signals into optical data streams, the hardware eliminates ground loop propagation and common-mode noise transmission across the 200 m media span. This optical isolation layout ensures stable 10 Mbps data transfer rates within high-interference industrial environments without requiring external signal isolation components.

Frequently Asked Questions

Q: Does the F3LR01-0N module support hot-swapping during active PLC backplane operation?

A: No. Power to the FA-M3 main unit and all connected sub-units must be completely deactivated before installing or removing the interface module to prevent electrical damage to the backplane bus logic.

Q: How does the system respond if an optical transmission channel error occurs?

A: The module automatically triggers a hardware shutdown of the associated I/O contact outputs on the affected sub-unit and transmits the precise physical location data of the transmission error to the central CPU.

Field Installation Guidelines

• Verify that the fiber-optic cable routing does not exceed the maximum transmission distance limit of 200 m between stations.
• Maintain the minimum bend radius specified by the fiber-optic cable manufacturer during routing to prevent signal attenuation and optical link failure.
• Ensure the surrounding atmosphere remains clear of corrosive gases, flammable gases, and heavy dust accumulations before mounting the hardware into the base unit slot.
• Secure the module into the FA-M3 main or sub-unit slot using the integrated locking mechanism to ensure stable physical connection with the backplane bus.
