When needing additional DF1 ports in your SLC system, the MVI46-DFCM Network Interface Module is the fastest and easiest way to add DF1 Half/Full Duplex Master and Slave capability. This module has two powerful and fully configurable DF1 ports allowing the many SCADA and field devices supporting the DF1 protocol to be integrated into the SLC platform. Devices commonly supporting the protocol include Rockwell Automation PLCs and power monitoring equipment, as well as several other third party devices. Each port is user-configurable to act as a Master or as a slave.
