1.3 Field Agent Architecture
The goal of Field Agent technologyis to connect industrial machines to the Predix* Cloud, so that asset owners can receive
insights and optimization for their equipment. Field Agents connect and transmit this data securely. Operators can then
visualize the performance of their assets and enable predictive analytics. Armed with this valuable information, operators can
optimize equipment uptime. OEMs can proactively maintain and service their equipment fleet, improving operations, growing
service revenues and winning new business. Asset owners can evolve past a break-fix model and implement predictive
analytics to minimize unplanned downtime.
GE has developed a family of Field Agent devices to address the challenges of communicating equipment data. A Field
Agent has two primary functions:
• Collecting and transmitting machine data securely
• A platform for running applications at the edge
Once a Field Agent is up and running, data is transferred from the plant to the cloud over encrypted channels, preserving its
time stamp, quality, and fidelity. It also provides a rich domain application environment for edge processing, so logic can be
executed at the most appropriate place in the architecture — locally on the machine or in the cloud.

1.4 Mini Field Agent (MFA)
The GE Mini Field Agent* (MFA) module is a Machine to Cloud collector that securely forwards data to a Predix* Time
Series Database Service. The MFA is based on the ARM architecture and designed to meet low power, harsh environment
specifications for industrial use. It runs an embedded Linux® operating system and comes with Predix Machine pre-integrated
and ready to enroll in Predix EdgeManager. The Field Agent ecosystem enables end users ease of developing Predix solutions
using the MFA platform. The following figure depicts the typical installation of a MFA. The section Configure the Network
provides defaults IP addresses.

1.5 Embedded Field Agent (EFA)
The GE Embedded Field Agent (EFA) is available in two physical form factors: the Mark* VIe controller, which is part of the
ControlST family of products, and the CPE400 controller, which is part of the PACSystems* family of products. The EFA resides in
one of the virtual machines on the controller and uses the Ubuntu® operating system. It comes with Field Agent software including
Predix Machine pre-integrated and ready to enroll in Predix EdgeManager. While the EFA is essentially configured the same way
as an MFA, there are different Application and Configuration templates provided for the EFA. For instance, because the EFA has
more memory and a higher-performance CPU compared to the MFA, it can retain more “Store and Forward” buffered data in the
event of temporary loss of communications to the cloud. Therefore, the Store and Forward configuration files for the MFA and EFA
are different.
1.5.1 Mark* VIe IS420UCSCH1A CPU w/ Field Agent
The Mark* VIe UCSC EFA uses the IICS Cloud Port (found on the bottom of the UCSC) to both communicate to controllers to gather
data, as well as to connect to the Predix Cloud. For more information about the UCSC itself, please see GEH-6721_Vol_II Mark* VIe
and Mark* VIeS Control Systems, Volume II: General-purpose Applications.
1.5.2 PACSystems IC695CPE400 RX3i Rackless CPU w/ Field Agent
The CPE400 EFA uses the EFA Port (found on the bottom of the CPE400) to connect to the Predix Cloud. It uses an internal virtual NIC
to communicate with the controller to gather data. The CPE400 also contains a display, which is described in the EFA HW Instructions
portion of this document. For more information about the CPE400 itself, please see PACSystems RX7i & RX3i CPU Reference Manual,
GFK-2222Y or later.

1.6 Virtual Field Agent (VFA)
The GE Virtual Field Agent (VFA) is a Virtual Machine that uses the Ubuntu operating system. It contains Predix Machine to allow
streaming data to the cloud or running applications locally. It also incorporates User Interfaces for configuring networks and time
synchronization, getting Field Agent Product and Linux OS Updates, and checking status and running commands. While the VFA is
essentially configured the same way as an MFA or VFA, there are different Application and Configuration templates provided for the
VFA, because these templates are associated with a specific version of Predix Machine. Currently the Virtual Field Agent is normally
distributed as one of the possible Virtual Machines on a Control Server. To learn more about Control Servers, please see GEH-6851
Control Server – High Availability (HA) Maintenance Guide and GEH-6852 Control Server – Simplex Maintenance Guide.

2 MFA Hardware Instructions
2.1 Internal Components
Caution
The only user-serviceablecomponents in the Mini Field Agent are the Real Time Clock
Batteryand cellular SIM card. Do not remove or alter any other components on the Mini
Field Agent.
The MFA module is shipped with a battery pre-installed. The battery holder is located below the Supercap, and can be
replaced by opening the top cover.
To replace the battery
1. Power OFF the MFA Module.
2. Wait for 1 minute.
3. Open the top cover by loosening the four screws on the edges.
4. Use a small flat-head screw driver to gently pry out the old battery.
5. Insert the new battery.
Replace battery only with Rayovac BR2032 or part IC690ACC001Bor later. Use of
another battery may present a risk of fire or explosion.
Warning Battery may explode if mistreated. Do not recharge, disassemble, heat above 100 °C
(212 °F) or incinerate.
The MFA module has an optional cellular modem. The SIM is available as a pre-installed option or may be installed by the
customer. The SIM card holder is located underneath the cellular modem and can be installed by opening the top cover and

Mounting Kit is required to use the Panel Mount option. After mounting the MFA, connect it to the facility network using
standard Ethernet cables. The LAN interface should be connected to the local area network containing one or more industrial
devices. The WAN interface should be connected to a network with access to the Internet.
