Figure 5 shows a typical Field Agent application, in which the role of the CPE400 Embedded FieldAgent (EFA) is to gather data locally, then securely transfer selected data to the Predix Cloud via the
EFA port. The PACSystems RX3i maintains control over the remaining Ethernet ports on the CPE400,
as well as its serial port. Data from the local environment, obtained via any of these ports, can be
manipulated by the RX3i PLC and tagged for use in the Field Control application.
The remote user with an acceptable security profile can then access data in the cloud from multiple
installations, aggregate selected data and make decisions based on the bigger picture. For instance,
the CPE400 could be installed in a control system monitoring a single wind turbine. The remote user
might be monitoring several hundred such turbines. With a suitable dashboard-style application on
his computer, the remote user could identify turbines that need to come offline for maintenance, or
turbines whose power generation output could be enhanced or retarded to fit demand.
To utilize the EFA port (for detailed steps, refer to the Field Agent User’s Guide, GFK-2993):
1. Connect a Cat 6 Ethernet cable between a computer and the CPE400 EFA port.
2. Set the IP address of the computer to 172.31.0.101 (or any IP address on the 172.31.0.0/16
subnet other than 172.31.0.100, which is the default IP address for the CPE400 EFA port).
Note that the EFA IP address can be read from the CPE400’s OLED display in the “FA Settings”
-> “Network Config” -> “IP Address” and “Subnet Mask”.
3. Use the OLED display to enable Configuration Mode by toggling “FA Settings” -> “Commands”
-> “Config Mode”. The Predix Machine Web Console is only accessible while the EFA is in
Configuration Mode. Note that Configuration Mode will automatically disable after one hour if
not explicitly disabled earlier.
4. Using a browser on the computer, browse to the Predix Machine Web Console at
https://172.31.0.100:8443/system/console. The Google Chrome browser is recommended for
accessing the Predix Machine Web Console.
a. Log in using the default password, then update the password.
b. Verify that the Log Service page displays. This confirms that log in has been successful.
c. Configure the EFA port for WAN network.
d. Configure a Network proxy, if required.
e. Configure Time Synchronization.
f. For maximum security, update the Field Agent firmware before connecting to the
Internet. This procedure is outlined in the Field Agent User’s Guide, GFK-2993. See the
chapter on Updating the Field Agent, specifically Method 1: Manual Local Update Using a
Local Area Network.

5. Provide a means of connecting to the Internet.
6. Enroll the CPE400 in the Predix Cloud:
a. The Administrator logs into the EdgeManager and creates one of the following:
i. Two user accounts: one with the Operator role and the other with the Technician role
ii. One user account with both the Operator and Technician roles
b. From the customer’s EdgeManager URL, the Operator logs into the EdgeManager and
creates a Field Agent device representation with the desired Device Name and Device ID.
c. The Operator assigns the newly created Field Agent device to an EdgeManager user with
the Technician role.
d. The Technician obtains the following enrollment information from the Operator:
i. The EdgeManager Enrollment URL
ii. The User Authentication and Authorization (UAA) URL used to authenticate the
Technician
iii. The Device ID selected by the Operator
iv. The device’s Activation Code
e. The Technician logs into the Web Console on the Field Agent to be enrolled, and navigates
to the Predix Cloud Enrollment page under Technician Console, Predix Cloud Enrollment.
f. The Technician enters the enrollment information, presses the Enroll Device button, and
authorizes the enrollment (which may include providing the Technician’s EdgeManager
Username and Password).
g. From EdgeManager, the Operator verifies that the Field Agent is displayed as Reachable.
7. For security, toggle Configuration Mode to disable access to the Predix Machine Web
Console.
8. Disconnect the local computer once enrollment has been completed.
9. Configure and Manage the activities on the EFA using Predix EdgeManager. This involves
selecting tags in the CPE400’s OPC-UA server and configuring these as read, write or
read/write. In this way, the system is set up to allow data to pass securely from the CPE400 to
