3. Key Features

Compact & Cost-Effective

• 35% smaller than FC900B, ideal for slim I80 setups

• Lower power consumption, reducing system load

Dual-Port Communication

• Two independent ports for simultaneous connection to DNC + HMI

• Hardware-driven transfer, no CPU performance impact

Protocol Versatility

• Supports standard DNC for online machining

• Compatible with Yaskawa HMIs and third-party controllers

• Switchable RS-232 (point-to-point) / RS-422 (multi-drop)

4. Compatibility & Configuration

Required Boards

• CPU: JANCD-FC250 / FC251

• PLC Core: JANCD-FC500

• Backplane: JANCD-FC001

Typical System Setup

• Compact DNC: FC250 + FC500 + FC900C + FC810

• HMI Link: FC251 + FC500 + FC900C

Limitations

• Max 1 board per system

• Occupies one full slot on FC001 backplane

5. Common Faults

• Communication timeout: Cable fault, baud rate mismatch

• Port failure: ESD damage or driver chip burnout

• Bus error: Backplane contact issue

• No power: 24 V loss or internal fuse blow

6. Applications
