2.1 Characteristics
The FL EPA 2 is an industrial wireless module for the wireless integration of industrial
Ethernet and PROFINET devices in cable-based networks through WLAN and/or
Bluetooth.
Among others, the FL EPA 2 is designed for the following typical applications:
– Wireless network connection for industrial machines, devices and vehicles
– Ethernet cable replacement between moving machine parts
WLAN or Bluetooth?
WLAN is the preferred technology when it is important to integrate multiple devices with high
data throughput and fast roaming.
Bluetooth has benefits if the application requires especially robust wireless connections or
if precise cable planning is not possible.
2.1.1 Device versions
Three device versions are available:
Depending on the model, not all of the properties described above are available.
2.2 Country approvals for the FL WLAN EPA
An up-to-date list of the country approvals can be found in the e-shop at
phoenixcontact.net/products.
The implementation of the Bluetooth PAN profile on mobile devices is not uniform and may
possibly be incompatible with the FL EPA 2. A Bluetooth PAN connection must be tested
individually.
5 GHz WLAN cannot be used at the same time as 2.4 GHz WLAN or Bluetooth.
The performance of both wireless modules is degraded if WLAN and Bluetooth are
activated simultaneously. Only one of the two wireless standards should be active for
applications that require maximum performance or real-time characteristics!

4 Configuration
There are different ways of configuring the EPAs for operation:
Easy Config (“MODE” button)
Typical operating modes, such as direct connection of two EPAs to form a “wireless
Ethernet cable”, can be directly activated via the MODE button on the EPA. A PC is not
required. For a detailed description, please refer to Section 4.0.1 “Easy Config (“MODE”
button)” on page 16.
Web-based management (WBM)
The device includes a web-based management using a web browser. You can see the
current operating state and configure the device without using special software.
For parameter description, please refer to Section “Web-based management” on page 21.
AT commands
You can carry out all the EPA settings automatically from a control program, for example.
For this purpose, send the command to TCP port 8080 of the device. For development or
testing purposes, AT commands can also be transmitted to the EPA via the web-based
management.
The AT command reference can be found, for example, in the web-based management
application under the “Help” menu item.

4.0.4 Easy Config modes
Modes 5 to 9 are used for defining the operating mode of the network (WLAN/Bluetooth,
with or without optimization for PROFINET operation). Set the device, which will later act as
an access point/NAP, to the desired mode.
Configure the clients for mode 4. The access point or NAP then configures the devices in
mode 4, matching the selected operating mode. As soon as a device is configured as a
client, the device is restarted.
The access point scans for configurable devices for 120 s (the scan can be canceled by
switching it off and on). The device is then also restarted. The connection is established
automatically.

Configuration
108452_en_01 PHOENIX CONTACT 19 / 50
The access point retains the configured IP address. The clients/PANU are assigned the IP
addresses in ascending order or - if not possible - in descending order.
Example: Based on the factory settings, the AP/NAP IP address is 192.168.0.254. The IP
addresses 192.168.0.253, 252, … are then assigned to the clients.
If the AP has previously been configured to 192.168.3.50, it will retain this address.
192.168.3.51, 52, … are then assigned to the clients/PANU.
A WLAN connection is established on channel 6. The channel can also be changed
subsequently using the access point web interface.
The connection is layer 2-transparent and thus also suitable for PROFINET.
If several wireless sets are used within a common backbone network, configuration via
Easy Config may lead to double assignment of IP addresses. This is due to the fact that
each wireless set starts at 192.168.0.254. In this case, assign unique addresses
beforehand or subsequently using the web interface.
For functionally safe communication, please refer to the information in Section “Safety-
related communication (PROFISafe/SafetyBridge)” on page 39.
