5.8.4 DF1 Command Set For ProSoft Technology Communication
Modules
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 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. 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:
