The MVI56-DFCM is a DF1 serial communication module from ProSoft Technology, engineered to connect Rockwell Automation ControlLogix processors to DF1 protocol-compatible devices. The MVI56-DFCM mounts in a single 1756 chassis slot and features two independently configurable serial ports supporting RS-232, RS-422, or RS-485 interfaces. Each port can be configured as a DF1 Master or Slave, with support for both half-duplex and full-duplex modes. The MVI56-DFCM provides up to 5,000 registers of user data storage and supports up to 100 commands per Master port. With 500V optical isolation and Class I Division 2 hazardous location certification, the MVI56-DFCM delivers reliable DF1 connectivity for demanding industrial applications.
SCADA Systems – Pipeline and offshore platform data concentration and monitoring
Foreign Device Data Concentration – Aggregating data from multiple DF1 devices to a ControlLogix processor
Power Monitoring – Interfacing with Rockwell Automation power monitors (RS-485 half-duplex, DFCM as Master)
Food Processing – DF1 communication for process control and equipment monitoring
Mining – Connecting DF1 devices in harsh industrial environments
Pulp and Paper – DF1 integration for production line control systems
Remote I/O Applications – Ideal for ControlNet or Ethernet applications with the module in a remote rack
HMI Integration – Connecting PanelView HMIs (full-duplex point-to-point, DFCM as Slave)
Single-slot, 1756 backplane compatible; supports local or remote rack
Two application serial ports, independently configurable as Master or Slave
Supports RS-232, RS-422, and RS-485 interfaces (jumper-selectable)
Full and half-duplex DF1 protocol support
Full hardware handshaking control for radio, modem, and multi-drop support
Up to 100 commands per Master port, with configurable polling (disabled, continuous, on-change)
Comprehensive LED indicators: Module Status, Backplane Transfer, Application Status, Serial Activity
RJ45 Configuration/Debug port with included RJ45 to DB-9M cable
Class I, Division 2, Groups A, B, C, D hazardous location certified
Includes sample ladder logic for rapid integration
True DF1 Master/Slave Flexibility – Each of the two ports can be independently configured as a Master (issuing commands) or Slave (responding to commands), providing unmatched application versatility compared to fixed-function serial modules.
Comprehensive Protocol Support – Full and half-duplex DF1 with CRC/BCC error checking, plus support for PLC-5 and SLC-500 command sets, ensures compatibility with legacy and modern Rockwell Automation devices.
Hardware Handshaking for Modem/Radio – Full hardware handshaking control enables reliable communication over radio links and modems, a critical feature for SCADA and remote monitoring applications where standard modules fail.
500V Optical Isolation – Protects the ControlLogix backplane from electrical noise and transients on field serial lines, enhancing system reliability in electrically noisy industrial environments.
High-Density Command Processing – Supports up to 100 commands per Master port with configurable polling intervals, enabling efficient data collection from multiple slave devices without overwhelming the ControlLogix processor.
Hazardous Location Ready – Class I Division 2 certified, allowing deployment in potentially explosive atmospheres where many competitive modules cannot be used.
Floating-Point and Multi-Typed Data Support – Handles floating-point data movement and multiple data types, simplifying integration with devices that use non-integer data formats.
Proven Interoperability – Tested with RA PanelView, RA Processors, and RA Power Monitors, ensuring reliable connectivity with the most common Rockwell Automation field devices.
Q1: What is the difference between the MVI56-DFCM and the MVI56-DFCMR?
A1: The MVI56-DFCMR is a variant with a Reduced Data Block designed for remote chassis applications (ControlNet or Ethernet), using a smaller I/O data area for data transfer. The standard MVI56-DFCM uses a larger data block and is suitable for local rack installations.
Q2: Can the MVI56-DFCM operate as both a Master and a Slave simultaneously?
A2: Yes. Each of the two serial ports can be independently configured—one port can act as a Master while the other acts as a Slave, or both ports can be configured identically.
Q3: What serial interfaces does the MVI56-DFCM support?
A3: The module supports RS-232, RS-422, and RS-485 interfaces. The interface type is selected via jumpers on the module. The CFG debug port is RS-232 only.
Q4: How many commands can be configured on a Master port?
A4: Each Master port supports up to 100 commands. Each command is fully configurable for function, slave address, register addressing, and word/byte count.
Q5: Does the MVI56-DFCM provide electrical isolation on its serial ports?
A5: Yes. The two application serial ports provide 500V optical isolation from the ControlLogix backplane. The debug/configuration port does not provide isolation.
