More Information

Overview Manuals Specifications DF1 Protocol Serial Links Legacy Support

Features:

  • Two configurable DF1 serial application ports
  • DF1 full- and half-duplex operation
  • Master and Slave communication modes
MVI56-DFCM adds two DF1 channels to a ControlLogix rack for communication with Allen-Bradley serial devices and compatible DF1 nodes.

Its ports support full-duplex and half-duplex networks, with Master or Slave behavior selected to suit the polling and response architecture.

When maintaining an MVI56-DFCM installation, document the duplex mode, station addresses, serial timing, cable pinout, message commands, and controller data map.

The ProSoft MVI56-DFCM DF1 Master/Slave Communication Module is listed as Discontinued / Obsolete by OEM. Apter Power provides legacy sourcing and DF1 application review.

ProSoft MVI56-DFCM DF1 Master/Slave Communication Module Specs

General

  • ManufacturerProSoft Technology
  • ModelMVI56-DFCM
  • ConditionNew Original ready stock
  • Product FamilyControlLogix Communication Module

Duplex and station roles

  • Full duplex: Point-to-point or switched DF1 links can use full-duplex messaging.
  • Half duplex: Multidrop networks can use half-duplex Master or Slave operation.
  • Master functions: Configured commands allow the module to initiate supported DF1 data transfers.
  • Slave access: Slave mode responds to requests addressed to the configured DF1 station.

Port-level engineering

  • Two channels: MVI56-DFCM supplies two separately configurable serial application ports.
  • Communication rate: The documented baud range is 110 to 115200 baud.
  • Physical connection: Verify the required cable, electrical interface, handshaking, and termination for each DF1 link.
  • Timing values: Response timeout, retries, polling, and station addressing must match the network design.

Migration preparation

  • Official status: MVI56-DFCM is retained in the ProSoft legacy download area.
  • Configuration archive: Save the module configuration, ladder logic, command list, firmware details, and serial drawings.
  • Migration note: ProSoft provides a technical note for moving MVI56-DFCM or DFCMR applications to PLX51-DF1-ENI.
  • Engineering check: A migration still requires review of DF1 roles, message paths, data addresses, cabling, and controller logic.
Description
The MVI56-DFCM is a high-performance DF1 communication module designed by ProSoft Technology for Allen-Bradley ControlLogix® systems. It supports both half-duplex and full-duplex operation and can be configured as a master or slave device. This module allows ControlLogix controllers to reliably communicate with a variety of DF1-compatible devices, including PLCs, RTUs, SCADA system terminals, and various industrial automation equipment, via RS-232, RS-422, or RS-485 serial interfaces.

The MVI56-DFCM is rack-mounted within ControlLogix enclosures, requiring no additional power supply or complex wiring, facilitating rapid deployment in existing systems. It supports configurable communication parameters, including baud rate, data bits, stop bits, and parity, adapting to the communication needs of various industrial environments.

The MVI56-DFCM is particularly suitable for retrofitting legacy equipment, expanding serial buses, and upgrading mixed new and legacy systems. By providing clear master/slave switching and flexible port configuration, the module easily enables networking of multiple devices while ensuring communication stability and data integrity. In addition, the module has industrial-grade tolerance, including a wide temperature range and resistance to shock and vibration, enabling it to operate reliably for extended periods in harsh industrial environments.
