5.7 DF1 Command Set For ProSoft Technology Communication Modules
5.7.1 Introduction
This document contains a complete description of the command set required to
communicate with DF1 protocol devices using a ProSoft communication module.
ProSoft communication modules that contain a virtual DF1 master device use
this command set to control and monitor data in DF1 protocol devices. These
include Rockwell Automation PLC, SLC, MicroLogix and ControlLogix controllers
and field devices supporting the DF1 protocol. ProSoft supports the DF1 protocol
on both the serial and network interface. The network interface requires the use
of the port service address 0xAF12 as specified in the ControlNet Specification.
Rockwell Automation supports this feature in the ControlLogix 5550, PLC5 xx/E
and SLC 5/05 processors.
The ProSoft modules contain a virtual database that is defined by the user. This
database is used as the source for write commands and the destination for read
commands issued on the virtual DF1 master devices. The module interfaces data
contained in remote DF1 slave devices to the virtual database using the DF1
master. User commands are issued out of the DF1 master from a command list.
These commands gather or control data in the DF1 slave devices. The following
illustration shows the relationships discussed above:
