Product Specifications
The MVI56 DF1 Master/Slave Communication Module allows Rockwell
Automation ControlLogix compatible processors to interface easily with DF1
protocol compatible devices and hosts. Devices commonly supporting the
protocol include Rockwell Automation PLCs and power monitoring equipment, as
well as several other third party devices in the marketplace.
The MVI56-DFCM module has two Application Serial ports supporting the DF1
protocol, with each port user-configurable to act as a Master or as a slave. Data
transfer between the module and the ControlLogix processor is asynchronous to
the DF1 network, with the module’s internal database being used to exchange
data between the processor and the DF1 network.
