GE Fanuc IC200ACC415 VersaMax RS-232 to RS-485 Converter Adapter

The IC200ACC415 is an RS-232 to RS-485 converter adapter for GE Fanuc VersaMax Micro and Nano PLCs. It converts the PLC's RS-232 serial port to an RS-485 multi-drop bus, enabling communication with up to 8 slave devices per network (expandable with repeaters). The adapter is powered directly by the PLC — no external power supply required.

Installation Guide

1. Connect the IC200CBL500 cable from the PLC's RJ-45 serial port to the IC200ACC415's 9-pin RS-232 input.
2. Connect the IC200ACC415's 15-pin RS-485 output to the RS-485 network bus.
3. Mount the adapter on DIN rail or panel using supplied hardware.
4. Verify TX/RX LEDs blink during data transmission.
5. Configure PLC serial port for SNP master/slave, RTU slave, or Serial I/O as needed.

FAQ

Q: Does IC200ACC415 need external power?
A: No. It draws power directly from the host PLC's serial port (+5VDC on pin 7, max 100mA).

Q: What cable do I need?
A: The IC200CBL500 (RJ-45 to DB9 female) is required to connect the PLC to the adapter.

Q: How many devices can I connect?
A: Up to 8 slave devices per RS-485 network. Use a repeater to expand beyond 8.

Q: What is the maximum communication distance?
A: Up to 1,200 meters with proper RS-485 cabling.

Q: Will it work with older VersaMax PLCs?
A: Yes. It is compatible with all VersaMax Micro and Nano PLCs.

Q: What do the LEDs indicate?
A: TX LED = data being transmitted; RX LED = data being received. If LEDs stop blinking, check cable connections.

Selection Tips

• RS-232 to RS-485 conversion for Micro/Nano: IC200ACC415 + IC200CBL500
• Direct RS-485 on 23/28-point Micro (Port 2): No adapter needed — use DB-15 port directly
• USB programming: IC200USB001 / IC200USB002
• Serial programming cable: IC200CBL001
• Always verify: PLC model, serial port type, and required cable before ordering
