3 Function and System Design
3.1 Function
Fieldgate FXA320 is designed for inventory control applications. It possess two 4...20 mA input
circuits which can be switched to be passive (connected device has own power supply) or active
(Fieldgate powers the connected device). An additional four binary inputs for switches or counter
applications are available as an option.
3.1.1 Inventory Control
Fieldgate FXA320 allows owners, vendors and suppliers to remotely acquire the current levels of
products in tanks or silos, e.g. in order to account for them in their own production planning. The
Fieldgate allows level limits to be configured and, if required, automatically activates the next
delivery. The options here range from a simple purchasing requisition via e-mail through to fully
automatic order administration when XML data is coupled into the planning systems on both sides.

3.2 Communication interface
Fieldgate is equipped with an Ethernet 10BaseT interface, an analog modem or a GSM modem.
3.2.1 Ethernet 10BaseT
Fieldgate with 10BaseT Ethernet interface is connected to the local network via a hub or switch
using a standard cable with RJ45 plug connector. As Fieldgate is constantly available in the network,
it is accessed with a standard web browser. Several PCs can access Fieldgate simultaneously.
Fig. 3-2: Connecting Fieldgate to Ethernet
3.2.2 Telephone network
Fieldgate is connected to the 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. The Windows internal telecommunications network can be
used for dialling. After this, the Fieldgate can be accessed with a standard web browser.
Fieldgate can also dial itself into a central server, e.g. in order to deliver periodic measured values.
If Fieldgate dials into the Internet permanently via an Internet Service Provider, it is possible for
several users to access the Fieldgate simultaneously. In addition the user does not require a modem
as a receiver at the work place.

3.2.3 Mobile communications network (GSM)
The GSM modem allows data to be transferred via a mobile communications network. It 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 is established via the data channel of the SIM card, which may require additional
activation, depending on the GSM provider.
Fig. 3-4: Connecting Fieldgate to a mobile communications network
3.2.4 GPRS support
GPRS (General Packet Radio Services) is a mobile communications technique, which exploits the
advantages of packet-oriented data transmission and channel bundling.
In contrast to 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 are compiled into
packets, which can be sent depending on requirement and capacity. Data transmission in packets
enables not only greater transmission rates but also permanent dial-in operation. The Fieldgate is
thus permanently in a position to connect to the Internet, an Intranet or a mailbox, whereby data
are only transferred as required, e.g. if a new e-mail is sent or a new Internet page is called up. In
this case, 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. Permanent dial-in allows
optimal use of Fieldgate’s web page functions, providing Internet access via WAP or HTML and PC.
To use some GPRS functions, e.g. access to the Fieldgate via Internet, 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.

3.3 Signal channels
Fieldgate FXA320 has two analog input channels, optionally four binary input channels and a relay
output channel. More details are to be found in Chapter 3.5, System Architecture and Chapter 4,
Installation.
3.3.1 Analog input channels
Two analog input channels allow the connection of two 4...20 mA devices. A switch behind the
front panel allows them to be individually configured to be passive (connected device has own
power supply) or active (Fieldgate powers the connected device).
3.3.2 Binary input channels
Four binary input channels, comprising two blocks of two channels with common ground, are
available as an option. The inputs can be used as follows
• Inputs 1, 2, 3, 4: switching status: L-signal: -3 ... +5 V, H-signal: +15 ... +30 V
• Inputs 1, 3: event counting: measuring range 0 ...12.5 kHz
• Inputs 2, 4: frequency measurement: 4.7 Hz (±1%) ... 12.5 kHz (±4%)
The input channel is configured using the Fieldgate Web server.
3.3.3 Relay output
The relay can be used to signal an alarm or save power:
• Alarm relay
The relay is configured as an alarm relay by not selecting the function "Power Down Devices
between Scan Cycles" on the device set-up page. It closes on power-up and opens on power-
down. The alarm circuit must be wired accordingly.
• Power save
For installations where power saving is at a premium, e.g. solar stations, the device power can
be wired via the relay. The function "Power Down Devices between Scan Cycles" is then
selected by ticking the checkbox, see Chapter 6.3.4. When the device scan is complete, the
relay is opened and the power to the devices is cut. When the next scan is due, the relay closes
and after a short delay to allow the device to power-up, the scan proceeds.
