5.1 Product Specifications
The MVI56 DF1 Master/Slave Communication Module with Reduced Data Block
is a ControlLogix backplane compatible module that allows ControlLogix I/O
compatible processors to easily interface 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.
This module uses a small I/O data area for data transfer between the module and
the ControlLogix processor, making it ideal for ControlNet or Ethernet
applications with the module in a remote rack.
The MVI56 DF1 Communication Module for Remote Chassis allows ControlLogix
I/O compatible processors to interface easily with other DF1 protocol compatible
devices.
The module has two 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.
