Fieldgate FXA320, FXA520
Gateways / Interfaces
Gateway for Remote Monitoring of Sensors and Actuators
via Web Browsers
Their integrated time control make Fieldgates suitable for
all applications in which more distant measuring points
have to be sporadically analysed. Configurable
monitoring of limit values with alarm signalling via email or SMS make it possible to react directly to changes
on-site.
The supported data transfer in XML format allows for
simple further analysis and processing of the measured
data, through to integration into complex planning
systems.

Application
Fieldgates enable remote monitoring of connected 4...20
mA sensors/actuators, either via telephone lines
(analogue), Ethernet TCP/IP or mobile communications
(GSM). The measured data is web compatible (HTTP,
HTML, WML) and can, therefore, be analysed in the
web browser without additional software.
For remote diagnosis and remote configuration, HART
sensors are suitable in conjunction with FXA520.
30 measuring points
• Up to 4 measured values can be displayed per device
(HART)
• Intrinsically safe version [EEx ia]IIC for applications in
hazardous areas
• Remote diagnosis and remote configuration of
connected HART devices
• Applicable in 4...20 mA SIL 2 Loops (IEC 61508)

Fieldgate FXA320, FXA520
Applications
Vendor Managed Inventory By using Fieldgates to interrogate tank or silo levels remotely, suppliers of raw materials can provide their
regular customers with information about the current supplies at any time and, for example, account for them
in their own production planning. For their part, the Fieldgates monitor the configured level limits and, if
required, automatically activate the next supply. The spectrum of options here ranges from a simple purchasing
requisition via e-mail through to fully automatic order administration by coupling XML data into the planning
systems on both sides.

Fieldgates not only transfer the current measured values, they also alert the responsible standby personnel, if
required, via e-mail or SMS. In the event of an alarm or also when performing routine checks, service
technicians can diagnose and configure connected HART devices remotely. All that is required for this is the
corresponding HART operating software (e.g. ToF Tool - FieldTool Package, ReadWin, ...) for the connected
device. Fieldgate passes on the information transparently, so that all options for the respective operating
software are available remotely. Some on-site service operations can be avoided by using remote diagnosis and
remote configuration and all others can at least be better planned and prepared.

Communication interface
Internet connection If the Fieldgate dials into the Internet permanently via an Internet Service Provider, it is also possible for several
users to access the Fieldgate simultaneously when using an analogue/GSM version. The other advantage is that
the respective user does not require a modem as a receiver at the work place.
Ethernet The 10 Base T Ethernet interface with RJ45 plug-in connection can be connected to the local network using a
hub or switch. A standard network cable is used for this. In Ethernet operation, you always have access to the
Fieldgate with a standard web browser, since the device is constantly available in the network. Several PCs can
access the Fieldgate simultaneously.

The Fieldgate is connected to the available telephone network via an RJ11 (PSTN) plug connector. This form
of communication is always a point-to-point connection and only one PC can communicate with the device at
any one time. In this configuration, the Fieldgate has to be selected before each access, so that it is ready for
online operation. For example, the Windows internal telecommunications network can be used for dialling.
After this, the Fieldgate can be accessed with a standard web browser (e.g. Internet Provider).
The Fieldgate is also capable of dialling itself into a central server, in order to deliver periodic measured values
for example. Here, it is also possible to transfer the measured values via the Internet using an Internet Service
Provider.

Mobile communications network (GSM)
If there is no Ethernet or telephone network available in the Fieldgate's operating location, the data can also be
transferred via GSM using the mobile communications network.
These communications versions can be configured as point-to-point connections or as freely accessible via the
Internet/Intranet. A SIM card from a mobile communications network operator is required for GSM operation.
Communication takes place via the data channel of the SIM card, which may require additional activation,
depending on the GSM provider.

GPRS support GPRS (General Packet Radio Services) is a mobile communications technique, which exploits the advantages
of packet-oriented data transmission and channel bundling.
Different from normal GSM connections, no complete channel is reserved for the duration of the connection
between the mobile device and the basis station, rather the data is packed into packets, which can be sent
depending on requirement and capacity. Data transmission in packets enables not only greater transmission
rates but also always-on-operation. The Fieldgate is thus permanently in a position to connect to the Internet,
an Intranet or a mailbox, whereby data is only transferred as required if a new e-mail is sent or a new Internet
page is called up. Here, you are only charged for the amount of data actually transmitted (and not for
connection time).
The GPRS mode of the Fieldgate GSM thus offers the easiest and most cost-effective option for connecting a
measuring point permanently to the Internet or an Intranet. Thanks to always-on-operation, the WAP functions
of the Fieldgate can also be used easily and cost-effectively.
To use the available GPRS functions, the GSM/GPRS provider will need to allocate a public IP address. It will
be necessary to determine in each individual case, whether this additional service is offered by the respective
operator.

HART - Multidrop configuration (FXA520 only)
• Only HART communication possible
• Up to 30 devices (2 x 15) can be connected
• When the maximum number of devices are connected, observe the following:
– Minimum operating voltage of the connected devices,
– Voltage drop at the communication resistor,
– HART conformity multi-drop of the connected devices,
– Current consumption of the connected devices
– Output characteristics of the power supply unit
– All connected devices must first be allocated their own HART polling address
• A HART communication resistor is already integrated into the device. When the internal communication
resistor is used, the permitted number of devices in multi-drop operation is reduced due to the limited
current-carrying capacity of the resistor.

All E+H measuring devices with the HART protocol can, therefore, be used to the full extent with
the Fieldgate
A current list of all E+H measuring devices that have the HART protocol can be found under:
• www.hartcomm.org: "HART Products/Product Catalogue/ ...".
All Endress+Hauser measuring devices with HART protocol can be connected to the Fieldgate.
Even 4...20 mA devices without HART protocol can be operated in conjunction with the Fieldgate, e.g. limit
switch (Liquiphant, ...). However, then only the measured value can be read. The remote maintenance
function is not given for 4...20 mA devices because the HART protocol is required for this function.
