1. PREFACE
1.1. INTRODUCTION TO THE DH485 ROUTER
This manual describes the installation, operation, and diagnostics of the Aparian DH485
Router. The DH485 Router provides intelligent data routing between EtherNet/IP and DH485
which can help simplify the migration from MicroLogix and SLC systems to ControlLogix or
CompactLogix platforms, where a DH485 interface is required.
The module can also be used for remote programming, bridging between Ethernet and
DH485.

1.2. FEATURES
The DH485 Router is able to transfer data from a DH485 device to a maximum of eight Logix
controllers. The module operates in one of four modes, simplifying the configuration for all
applications.
Mode Description Message Initiator
Transparent
PCCC
The
DH485
Router will redirect DF1 PCCC messages to a Logix
controller at a preconfigured EtherNet/IP path.
Logix PLC Mapping configuration may also required.
This mode also supports remote programming using RSLogix
500.
Remote
Device
Reactive Tag
The
DH485
Router will
convert
DF1 PCCC messages to Logix
controller tag reads or tag writes.
No Logix PLC Mapping configuration is required.
Remote Device
Scheduled Tag The DH485 Router transfers data between a DH485 device
and a number of Logix tags, using a preconfigured scheduled.
No Logix or remote device configuration is required.
DH485 Router
Unscheduled The DH485 Router transfers messages received from a Logix
Message Instruction.
Logix (Msg)
Table 1.1. – Modes of Operation
The DH485 Router is configured using the Aparian Slate application. This program can be
downloaded from www.aparian.com free of charge. Slate offers various configuration
methods, including a controller tag browser.
Hereafter the DH485 Router will be referred to as the module.
The module can operate in both a Logix “owned” and standalone mode. With a Logix
connection the input and output assemblies will provide additional diagnostics information
which will be available in the Logix controller environment.
The module uses RS485 for DH485 communication. The RS485 port uses a terminal block for
convenient installation.
A built-in webserver provides detailed diagnostics of system configuration and operation,
including the display of received DH485 communication packets, without the need for any
additional software.

1.3. ARCHITECTURE
The figure below provides an example of the typical network setup.
Figure 1.1. - Example of a typical network setup
By converting and redirecting DH485 messages from legacy devices to EtherNet/IP, the
module provides an interface for data exchange to Allen-Bradley ControlLogix and
CompactLogix platforms.
The DH485 Router can be used in redundant Logix controller systems.
Systems that rely on a central ControlLogix communicating to a number of remote DH485
devices, e.g. MicroLogix and SLC stations, may find the DH485 Router useful when upgrading
to newer ControlLogix processors. These systems can easily be upgraded using the DH485
Router without affecting the existing and often costly wireless infrastructure.
The DH485 Router in conjunction with the DF1 Router can be used to replace both 1761-NET-
ENI and 1761-NET-AIC. The old network architecture used the NET-ENI and NET-AIC to allow
the user to use Ethernet to connect to various SLC, PLC5, and MicroLogix controllers as shown
below.

networks to EtherNet/IP as shown below:

2. INSTALLATION
2.1. MODULE LAYOUT
The module has three ports at the bottom of the enclosure as shown in the figure below. The
ports are used for Ethernet, RS485, and power. The power port uses a three-way connector
which is used for the DC power supply positive and negative (or ground) voltage as well as the
earth connection.
The RS485 port uses a four-way connector. This provides connection for the communication
positive (+) and negative (-). The fourth connection is used for shielding the cable in high noise
environments.
The Ethernet cable must be wired according to industry standards which can be found in the
additional information section of this document.
Figure 2.1. - DH485 Router side and bottom view
The module provides three diagnostic LEDs as shown in the front view figure below. These
LEDs are used to provide information regarding the module system operation, the Ethernet
interface, and the auxiliary communication interface (RS485).

Figure 2.2. – DH485 Router front and top view
The module provides four DIP switches at the top of the enclosure as shown in the top view
figure above.
DIP Switch Description
DIP Switch 1 Used to force the module into “Safe Mode”. When in “Safe Mode” the module will not
load the application firmware and will wait for new firmware to be downloaded. This
should only be used in the rare occasion when a firmware update was interrupted at
a critical stage.
DIP Switch 2 This will force the module into DHCP mode which is useful when the user has forgotten
the IP address of the module.
DIP Switch 3 Reserved
DIP Switch 4 Reserved
