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.

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).

Installation

Revision 1.2
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

2.2. MODULE MOUNTING
The module provides a DIN rail clip to mount onto a 35mm DIN rail.
Figure 2.3 - DIN rail specification
The DIN rail clip is mounted on the bottom of the module at the back as shown in the figure
below. Use a flat screw driver to pull the clip downward. This will enable the user to mount
the module onto the DIN rail. Once the module is mounted onto the DIN rail the clip must be
pushed upwards to lock the module onto the DIN rail.
Figure 2.4 - DIN rail mouting

Revision 1.2
2.3. POWER
A three-way power connector is used to connect Power+, Power– (GND), and earth. The
module requires an input voltage of 10 – 28Vdc. Refer to the technical specifications section
in this document.
Figure 2.5 - Power connector
2.4. RS485 PORT
The four way RS485 connector is used to connect the positive (+) and negative (-)
communication conductors for serial communication. The shield terminal can be used for
shielded cable in high noise environments.
Figure 2.6 – RS485 connector
NOTE: The shield of the RS485 port is internally connected to the power
connector earth. Thus, when using a shield, it is important to connect the Earth
terminal on the power connector to a clean earth. Failing to do this can lower
the signal quality of the RS485 communication.
NOTE: When using a shielded cable, it is important that only one end of the
shield is connected to earth to avoid current loops. It is recommended to
connect the shield to the DH485 Router module, and not to the other DH485
device.

Revision 1.2
2.5. RS485 TERMINATION
All RS485 networks need to be terminated at the extremities (start and end point) of the
communication conductor. The termination is done by placing a resistor between the positive
and negative communication conductor. The value of the resistor will depend on the
characteristic impedance of the cable chosen, but generally ranges from 100 Ohm to 150
Ohm.
2.6. ETHERNET PORT
The Ethernet connector should be wired according to industry standards. Refer to the
additional information section in this document for further details.

3. SETUP
3.1. INSTALL CONFIGURATION SOFTWARE
All the network setup and configuration of the module is achieved by means of the Aparian
Slate device configuration environment. This software can be downloaded from
http://www.aparian.com/software/slate.
Figure 3.1. - Aparian Slate Environment
3.2. NETWORK PARAMETERS
The module will have DHCP (Dynamic Host Configuration Protocol) enabled as factory default.
Thus, a DHCP server must be used to provide the module with the required network
parameters (IP address, subnet mask, etc.). There are a number of DHCP utilities available,
however it is recommended that the DHCP server in Slate be used.
Within the Slate environment, the DHCP server can be found under the Tools menu.
Figure 3.2. - Selecting DHCP Server

Setup
Document No. D120-007 Page 15 of 73
Revision 1.2
Once opened, the DHCP server will listen on all available network adapters for DHCP requests
and display their corresponding MAC addresses.
Figure 3.3. - DHCP Server
NOTE: If the DHCP requests are not displayed in the DHCP Server it may be due
to the local PC’s firewall. During installation the necessary firewall rules are
automatically created for the Windows firewall.
Another possibility is that another DHCP Server is operational on the network
and it has assigned the IP address.
To assign an IP address, click on the corresponding “Assign” button. The IP Address
Assignment window will open.
Figure 3.4. - Assigning IP Address
The required IP address can then be either entered, or a recently used IP address can be
selected by clicking on an item in the Recent List.
If the “Enable Static” checkbox is checked, then the IP address will be set to static after the IP
assignment, thereby disabling future DHCP requests.
Once the IP address window has been accepted, the DHCP server will automatically assign the
IP address to the module and then read the Identity object Product name from the device.

Setup
Document No. D120-007 Page 16 of 73
Revision 1.2
The successful assignment of the IP address by the device is indicated by the green
background of the associated row.
Figure 3.5. - Successful IP address assignment
It is possible to force the module back into DHCP mode by powering up the device with DIP
switch 2 set to the On position.
A new IP address can then be assigned by repeating the previous steps.
NOTE: It is important to return DIP switch 2 back to Off position, to avoid the
module returning to a DHCP mode after the power is cycled again.
If the module’s DIP switch 2 is in the On position during the address assignment, the user will
be warned by the following message.
Figure 3.6. - Force DHCP warning
In addition to the setting the IP address, a number of other network parameters can be set
during the DHCP process. These settings can be viewed and edited in Slate’s Application
Settings, in the DHCP Server tab.
Once the DHCP process has been completed, the network settings can be set using the
Ethernet Port Configuration via the Target Browser.
The Target Browser can be accessed under the Tools menu.
