The current transformer (CT) must be purchased separately. Watlow CT
part number is 16-0246 (up to 50 amps).
Systems that are more than 50 amps need an interstage transformer. For
example, if you use a 300 amp CT, part number 16-0073, and an interstage
transformer, part number 16-0176, the 300 amp CT provides a 5 amp signal
to the interstage transformer. In turn, the interstage transformer provides a
20 mA maximum signal to the controller.

Watlow Series PD ■ 20 ■ Chapter 4 Ethernet Communications
Network security is a critical issue for any network. Be sure to work with your network administrator
to ensure that you follow best security practices to ensure a secure network environment. Here are some
items to consider when installing Ethernet based controls on any network.
• Use private IP addresses.
• Separate the process network(s) from business network(s).
• If external access is required, then have a single point of access to the process network.
• External access points should be protected by a firewall.
• External access points should be protected by a layer 3 switch or router.
• Access to the Internet should be indirect, going through an access point to the business
network on the way.
• Separate processes or cells using VLANs.
• Run virus protection software on all PC's on the process network.
Refer to the bottom of the web page navigation frame for the browser versions supported. You may access the Series PD and view controller parameters via an onboard Web (HTTP) server.
The Series PD supports full product configuration and monitoring of runtime parameters via MODBUS TCP over TCP/IP using a third party software package such as Lookout™, created and sold by National Instruments.
The 10BaseT Ethernet connection supports the TCP/IP stack. At the application layer it has an HTTP
(web) and Modbus server. The HTTP server provides a means of changing runtime parameters via
HTML. The TCP/IP stack supports DHCP client, Auto IP, Static IP, DNS client, and Netbios name
resolution.
Getting Started
1. Connect the Series PD to your computer's Ethernet port using a cross-wired RJ45 cable or connect the
Series PD to a switch/hub or network using a straight wired RJ45 Category 5 cable. The Series PD is
limited to a 10BaseT connection and will not work on an Ethernet port set for 100BaseT only. Use of a
10/100 switch/hub will overcome this issue if your PC has only a 100BaseT port.
2. Wire a 24V‡ (ac/dc) power supply to the Series PD power terminals. See wiring section.
3. Wire sensor inputs and controller outputs. See wiring section.
4. Power up the controller, switch/hub and PC.
5. Start your Internet browser. Enter the Browse at address of the Series PD into the browser’s address
field. See figure on next page for the Browse at address location on the left side label. Two different
Netbios names may be used to access the Series PD. Either PDxxxxxx, where xxxxxx is the first six
digits of the serial number, located on the left side label, or WATxxxxxx, where xxxxxx is the last six
digits of the Series PD MAC address. The MAC address is also printed on the left side label of the Series PD in the form xx:xx:xx:xx. See figure on next page.
Note: Browsing the Series PD using the Netbios name only works with Windows. The computer and Series PD must
be on the same logical network. Browsing using the IP address always works.
Note: If you are not using a DHCP server, it may take several minutes for both the Series PD and your computer to
get their IP addresses.
Ethernet Communications

Figure 21 — Browse at address, MAC address, and Serial number locations
6. When you change data on the Monitor Device page or access other web pages, you are prompted to en-
ter a Network Security user name and password. The factory defaults are:
user name - new
password - user
7. Once you enter the user name and password you can access the other controller pages. If you browse
another address or close your browser, you will be required to enter this information again.
8. To change security level passwords, go to Device Configuration > Network > Security.
9. To configure the Series PD, go to Device Configuration and set up the unit.
Note: The controller leaves the factory with all inputs, outputs and control loops set to off.
Go through each Device Configuration page and make the appropriate selections for your application.
Click the Submit button at the bottom of each page.
Note: Be sure to click the Submit button at the bottom of any Device Configuration screen to send your changes to
the controller. Changes are not entered into the controller until you submit them.
9. Select the Monitor Device page. The process values and set points are displayed. You can change con-
troller set point and the mode of operation, auto or manual. Select the parameter value you want to
change by clicking on it, enter the new parameter value and click the Submit button. This sends the
Series PD the new value and refreshes the Monitor Device page.
Note: Information on the Monitor Device page, including alarms and errors, is automatically refreshed once per second, if your browser supports Java Virtual Machine and is enabled to allow Java applets to run.
Network Services
The Series PD supports DHCP client, Auto IP, and Static IP for address assignment. Normally you
will not need to make any changes. The user is able to configure preferences as to which services are used
if available. Intelligence is employed within the Series PD to revert to backup IP assignment methods if
the primary method is unavailable. It will try DHCP first, then Auto IP to assign an IP address. This is
the same method that a Windows based computer uses to get an IP address.
When using Auto IP, the Series PD starts with the IP address 169.254.10.10. If this address is already
in use, it will randomly attempt other addresses in the 169.254.XX.XX subnet. As with any IP networking
device, the IP address assigned to the Series PD must be compatible with the network it is physically connected to.
Note: If you are using Auto IP, it may take several minutes for both the Series PD and your computer to get their IP
addresses.
The Series PD does support DNS client and Netbios name resolution. Configuration information may
be entered at the Network Display Setup page.
Note: If you forget the fixed IP address of your Series PD, short the jumper connections on the top of the unit (see page 5), turn
the input power off and back on again. This causes the Series PD to use DHCP first, AutoIP and finally fixed IP addressing to try
assigning an IP address. This allows you to read the current fixed IP address. Once the unit is powered up without the jumper
connections shorted, the Series PD returns to using the previous IP addressing settings.

Watlow Series PD ■ 22 ■ Chapter 5 Monitor Device Page
When accessing a Series PD controller through a browser, the Monitor Device page appears. The Monitor Device page contains real-time information representing the current process conditions. This information is loaded
when the Monitor Device page is browsed and is automatically refreshed once every second. The Monitor Device
page provides real-time information on:
• Input Status
• Control Loop Status
• Alarm Status.
Input errors and alarms appear on this page as a red box next to the related input or output. These are refreshed once a second.
If you try to change any values on the Monitor Device page, you are prompted to enter Network Password
information. The User Name is new and Password is user. Be sure to change your user name and password if
controller security is a concern. If you want your browser to remember the User Name and Password after you
enter it the first time, check the box, Save this password in your password list. If you close your browser, you
must re-enter your user name and password information.
Note: You must have Java Virtual Machine installed on your computer and Java must be enabled for the Monitor Device page to display
properly in your browser. Most browsers will already have this configured by default.

Navigation Frame
The left side of the Series PD web pages contain a navigation frame
that looks and operates much like Windows Explorer™. This frame does
not change as web pages are accessed and changed. The navigation area
contains folders and web page links. A plus (+) sign in front of a folder
indicates the folder can be expanded to show more information. A minus
(-) sign in front of a folder indicates the folder can be contracted to show
less information.
For example, if you click on the + sign in front of the Device Configuration folder or click on the Device Configuration folder itself, you expand the Device Configuration folder. The folders that appear contain
additional folders as indicated by the + sign in front of each folder. Click
on the + or - sign in front of any folder or click on the folder itself to expand or contract that folder.
When you see page links (underlined text), you can click on a link to
take you to a specific Series PD web page. For example, with the Inputs
folder expanded, click on the Analog Input 1 link to go to the Analog Input 1 Configuration page.
