1. PREFACE
1.1. FEATURES
The PLX51-HART-4I can convert up to four analog devices into either EtherNet/IP™, Modbus
TCP/IP®, or DNP3 TCP/UDP protocols. This includes 4 to 20 mA input devices, with or without
HART communications.
The conversion to EtherNet/IP enables a HART device to be added directly into a Rockwell
Automation Logix IO tree. The Modbus TCP/IP option enables a HART field device to be
viewed as a Modbus Server. The DNP3 option converts a HART field device into a DNP3
Outstation. The DNP3 option also supports Secure Authentication, ensuring secure
communications across the Ethernet network.
In addition, a rich collection of process and diagnostic information is provided directly into
Logix, without the use of any explicit messaging. HART commands can also be relayed to the
device using an EtherNet/IP message relay object. A DTM (Device Type Manager) is available,
further simplifying device configuration and management using an FDT frame. A built-in
webserver provides detailed diagnostics of system configuration and operation, as well as
field device specific diagnostics.
The PLX51-HART-4I is configured using the PLX50 Configuration Utility. This program can be
downloaded from https://www.prosoft-technology.com.
Hereafter, the PLX51-HART-4I will be referred to as the module.

2. INSTALLATION
2.1. MODULE LAYOUT
The module has six ports at the bottom of the enclosure as shown in the figure below. The
ports are used for Ethernet, the four analog HART channels, and power. The power port uses
a three-way connector, which is used for the DC power supply and the earth connection.
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. –Side view

Installation
Page 8 of 88
2.2. LED’S
The module provides six diagnostic LEDs as shown in the figure below. These LEDs are used
to provide information regarding the module system operation, the Ethernet interface, and
the status of each of the four analog HART channels.
Figure 2.2. –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, it 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 you have forgotten
the IP address of the module.
DIP Switch 3
Reserved
DIP Switch 4

2.3. 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 enables you to mount the
module onto the DIN rail. Once the module is mounted onto the DIN rail, the clip must be
pushed upward to lock the module onto the DIN rail.
Figure 2.4 - DIN rail mouting

Installation

2.4. POWER
A three-way power connector is used to connect Power+, Power- (ground), and earth. The
module requires an input voltage of 12 to 28 Vdc. Refer to the Technical Specifications section
in this document.
Figure 2.5 - Power connector
2.5. ANALOG (HART)
The Analog HART channels are connected using a two-way connector. The input channels are
internally loop-powered and can be connected directly to the field device signal terminals.
The input channels provide internal current limiting and electronic fuse protection.

The equivalent Analog Input circuit is shown below:
Figure 2.7 –Analog Input Equivalent Circuit
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
The network setup and configuration of the module is achieved by means of the PLX50
Configuration Utility. This software can be downloaded from https://www.prosoft-
technology.com/.
Figure 3.1. - PLX50 Configuration Utility

Setup
Page 14 of 88
3.2. NETWORK PARAMETERS
The module has 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 to use the DHCP server within the PLX50 Configuration Utility.
Within the PLX50 Configuration Utility, the DHCP server can be found under the Tools menu.
Figure 3.2. - Selecting DHCP Server
Once opened, the DHCP server listens 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.

Setup
Page 15 of 88
To assign an IP address, click on the corresponding “Assign” button. The IP Address
Assignment window opens.
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 read the Identity object Product name from the device.
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

Setup
Page 16 of 88
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.
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 the DHCP Server tab of
the PLX50 Configuration Utility’s Application Settings.
Once the DHCP process is complete, the network settings can be set using the Ethernet Port
Configuration via the Target Browser. The Target Browser is found under the Tools menu.
Figure 3.6. - Selecting the Target Browser
The Target Browser automatically scans the Ethernet network for EtherNet/IP devices.
Figure 3.7. - Target Browser

Setup

Right-clicking on a device reveals the context menu, including the Port Configuration option.
Figure 3.8. - Selecting Port Configuration
The Ethernet port configuration parameters can be modified using the Port Configuration
window.
Figure 3.9. - Port Configuration
Alternatively, these parameters can be modified using Rockwell Automation’s RSLinx
software.

3.3. CREATING A NEW PROJECT
Before you can configure the module, a new PLX50 Configuration Utility project must be
created. Under the File menu, select New.
Figure 3.10. - Creating a new project
A PLX50 Configuration Utility project will be created, showing the Project Explorer tree view.
To save the project, use the Save option under the File menu. A new device can now be added
by selecting Add under the Device menu.
Figure 3.11. - Adding a new device

Setup
Page 19 of 88
In the Add New Device window, select the PLX51-HART-4I module and click the Ok button.
Figure 3.12 –Selecting a new PLX51-HART-4I
The device will appear in the Project Explorer tree with its configuration window opened. The
device configuration window can be reopened by either double-clicking the module in the
Project Explorer tree or right-clicking the module and selecting Configuration.

Utility’s installation and operation documentation.

Setup

3.4. PLX51-HART-4I PARAMETERS
The PLX51-HART-4I parameters are configured using the PLX50 Configuration Utility. The
configuration form is divided into multiple tabs to configure the general, DNP3, and channel-
specific parameters.
When downloading the configuration into the module, it will be saved in non-volatile memory
that remains when the module is powered down.
NOTE: When a firmware upgrade is performed, the module clears all PLX51-
HART-4I configuration.
The general configuration consists of the following parameters:
