More Information

Overview Manuals Specifications Configuration Communication Application Scenarios

Features:

  • Dual configurable serial ports supporting independent DF1 master or slave operation with half-duplex and full-duplex communication.
  • User-configurable database supporting storage and transfer of up to 5000 registers with floating-point data handling.
  • Optimized reduced I/O data block architecture for efficient communication in remote ControlLogix, ControlNet, and Ethernet installations.
The ProSoft MVI56-DFCMR provides an effective way to integrate DF1-compatible equipment into ControlLogix automation systems. By supporting both local and remote rack installations, the module offers flexibility for distributed control architectures across a wide range of industrial processes. Its compatibility with numerous DF1 devices helps simplify system integration while extending communication capabilities.

Two configurable serial ports allow the module to communicate with PLCs, power monitoring equipment, radios, modems, and other DF1-enabled devices. Independent master or slave configuration on each port makes it suitable for data collection, controller-to-controller communication, and SCADA applications. Comprehensive communication settings enable adaptation to different serial network requirements without additional hardware.

The module is especially valuable in facilities that require dependable serial communications between modern ControlLogix processors and existing DF1 networks. Industries including mining, food processing, offshore production, pipelines, and pulp and paper benefit from its configurable memory management, asynchronous data exchange, and reliable communication diagnostics. User-defined ladder logic configuration also simplifies implementation within established Rockwell Automation control environments.

The MVI56-DFCMR ProSoft DF1 Half/Full Duplex Master/Slave Communication Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The ProSoft MVI56-DFCMR is a ControlLogix backplane-compatible communication module that enables Rockwell Automation ControlLogix I/O compatible processors to communicate with DF1 protocol compatible devices. It operates as a single-slot module and can be installed in either a local or remote rack, making it suitable for distributed industrial control systems. The reduced I/O data block design is particularly beneficial for ControlNet and Ethernet applications where the module is installed in a remote chassis.

Designed for flexible serial communication, the ProSoft MVI56-DFCMR features two independent DF1 serial ports that can each be configured as either a master or a slave. Both half-duplex and full-duplex operating modes are supported, along with CRC and BCC error checking for dependable data transmission. Full hardware handshaking provides compatibility with radios, modems, and multi-drop communication networks.

The module exchanges data asynchronously between the DF1 network and the ControlLogix processor through an internal database. Memory allocation is completely user configurable, allowing storage and transfer of up to 5000 registers between the processor and connected DF1 devices. Read and write command lengths of up to 125 words are supported, and floating-point data movement is available for applications requiring advanced process values.

When configured as a master, the ProSoft MVI56-DFCMR can read from and write to remote DF1 devices, allowing the ControlLogix processor to function as a SCADA sub-master. Each master port supports up to 100 fully configurable commands with adjustable slave addressing, register mapping, polling methods, and word or byte counts. Individual command error codes and slave status information simplify communication diagnostics.

The ProSoft MVI56-DFCMR is widely used in foreign device data concentrators, SCADA systems, pipelines, offshore platforms, food processing, mining, and pulp and paper industries. Configuration data is obtained through user-defined ladder logic, while data transfer between the module and processor is handled through the 1756 backplane. Tested hardware connections include Rockwell Automation processors, PanelView terminals, and power monitoring equipment, demonstrating broad compatibility across industrial automation applications.
