The MVI69-DFCM is a Master-Slave Communication Module created by Prosoft Technology, which allows CompactLogix and MicroLogix platforms to easily interface with DF1 protocol compatible hosts as well as devices. The most common devices that support the protocol include power monitoring systems, Rockwell Automation PLCs, and third-party devices available in the marketplace. This module comes with 2 application serial ports that can be user-configured to serve as master or slave ports. The transfer of data between the MVI69-DFCM and the CompactLogix or MicroLogix processor is often asynchronous to the DF1 protocol, with the communication module’s internal database being utilized for data exchange. This single-slot communication module is 1769 backplane-compatible and it offers CRC and BBC error checking capabilities. Both full and half-duplex data transfer modes are supported by the DF1 ports.
The MVI69-DFCM has a maximum power rating of 800 milliamps (mA) at 5 Volts DC and can be DIN rail or panel-mounted. It has an operating temperature range of between 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). This module suitable for use in various industrial applications, including food processing, SCADA system pipelines, mining, offshore platforms, paper making, and pulp manufacturing. The MVI69-DFCM’s DF1 ports can be independently configured as master ports. Once configured in Master Mode, this module is able to read and write (or transfer) data between remote DF1 devices and the processor, enabling the CompactLogix or MicroLogix platform to serve as a SCADA-based sub-master. Error codes are available on a personal command basis and a list of slave statuses is maintained for every active master port. This module also comes with a customizable polling of the command features that includes disabled, continuous, and “ON” data change. Each master port contains up to 100 commands that are fully configurable for slave address, word or byte count, function, and register addressing.
