5.1 Product Specifications
The MVI46 DF1 Master/Slave Communication Module is an SLC backplane
compatible module that allows Rockwell Automation SLC I/O 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 MVI46-DFCM Master/Slave Communications module allows Rockwell
Automation SLC I/O compatible processors to interface easily with other DF1
protocol compatible devices. Compatible devices include not only Rockwell
Automation PLCs (which all support the DF1 protocol) but also a wide
assortment of end devices.
The MVI46-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 SLC 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.
