Rockwell ProSoft MVI56-DFCM DF1 Half/Full Duplex Master/Slave Communication Module

Product Overview

The ProSoft MVI56-DFCM is a DF1 Master/Slave Communication Module for the Allen-Bradley ControlLogix platform. It provides two powerful and fully configurable DF1 ports allowing SCADA and field devices supporting the DF1 protocol to be integrated into the ControlLogix platform. Each port is user-configurable to act as a Master or Slave, supporting both DF1 Half-Duplex and DF1 Full-Duplex modes.

FAQ

Q: What devices support DF1 protocol?
A: Rockwell Automation PLCs (SLC 500, MicroLogix, PLC-5), power monitoring equipment, and various third-party devices.

Q: Can both ports be configured as Master?
A: Yes, each port is independently configurable as Master or Slave.

Model Selection Tips

• MVI56-DFCM = DF1 Master/Slave for ControlLogix
• For DF1 on CompactLogix, consider MVI69-DFNT
• For multi-protocol (DF1 + Modbus), consider MVI56E-MNETCR
• Verify DF1 device baud rate and mode compatibility
