Safety WirelessHART Fieldgate SWG70
1Safety
1.1 Designated use
Fieldgate SWG70 serves as a gateway for WirelessHART networks. It enables WirelessHART
devices to communicate with each other and manages security and connectivity. The
Fieldgate converts wireless device data to a format that is compatible with host systems.
NOTICE!
• The WirelessHART protocol may not be used to replace the wiring in the case of safety
applications with a control function.
1.2 Installation, commissioning and operation
The WirelessHART Fieldgate can be operated safely in compliance with the current
guidelines for technical safety and the latest EU directives. Wireless field devices and
adapters connected to the WirelessHART Fieldgate must also be operated in accordance
with the current guidelines for technical safety and the latest EU directives.
If the WirelessHART Fieldgate is installed incorrectly or used in applications for which it is
not intended, it is possible that dangers may arise.
Installation, connection to the electricity supply, commissioning, operation and
maintenance of the WirelessHART Fieldgate may only be carried out by trained, qualified
technical specialists authorized to perform such work by the facility's owner-operator. The
specialist staff must have read and understood these Operating Instructions and must follow
the instructions they contain. It is not permitted to modify or repair the devices in any way.
NOTICE!
• Changes or modifications to the Fieldgate not expressly approved by Endress+Hauser will
void the user’s authority to operate the equipment.
1.3 Operational safety
Location Fieldgate SWG70 fulfills the requirements of EU Guidelines for a number of applications.
The associated environmental conditions must be upheld. See the Technical Information
document for "WirelessHART Fieldgate SWG70" (TI00027S).
The device must not be installed at locations where corrosive vapors may be present.
Hazardous areas Fieldgate SWG70 is available in a version that can be mounted in an explosion hazardous
area. In order to ensure the necessary degree of protection:
• All seals must be undamaged and have been correctly fitted.
• All screws of the housing/housing cover must have been tightened with the appropriate
torque.
• Only cable of the appropriate size must be used in the cable glands.
• All cable glands must have been tightened with the appropriate torque, see (Chapter 5.5).
• All empty cable glands must have been sealed with sealing plugs.

Page 7
WirelessHART Fieldgate SWG70 Safety
When installing components in explosion hazardous areas:
• Ensure that all installation and maintenance personnel are suitably qualified.
• Check that all equipment has the appropriate safety certificates.
• Observe the specifications in the device certificates as well as national and local
regulations.
Coexistence of wireless
technologies
Operation CAUTION!
WirelessHART networks use the frequency spectrum between 2400 ... 2483.5 MHz according to IEEE 802.15.4. Various other wireless technologies also use this frequency spectrum,
for example WLAN and Bluetooth. Depending upon the situation, it is possible that these
different wireless technologies will affect each other.
When wireless technologies are used in an industrial environment, they must coexist without interfering with each other. If you find that systems are interfering with each other, take
appropriate measures to ensure the operation of all wireless systems, e.g. by reconfiguring,
enforcing a wireless compatibility policy, etc.
Maintain a minimum distance of 20 cm between the device antenna and the body of the user
and all persons in the vicinity at all times and for all applications and uses.
1.4 IT security
The Fieldgate SWG70 is equipped with security mechanisms to protect it against any
inadvertent changes to the device settings. Additional IT security measures in line with
operators' security standards and designed to provide additional protection for the device
and device data transfer must be implemented by the operators themselves.
The Fieldgate offers the following functions that increase IT security:
• WirelessHART security management (See Chapter 3.2.2 "WirelessHART security
management" on page 12 and see Chapter 8.2.1 "Basic Setup" on page 43.)
• Password for Web server (See Chapter 11.4 "Change Password (Web Server)" on
page 108.)
• Security certificate for Web server (See Chapter 11.7 "Upload Certificate (Web server)" on
page 110.)
See the Technical Information document "WirelessHART Fieldgate SWG70" (TI00027S) for
system-specific firewall configurations such as TCP/IP ports and services.
1.5 Declaration of Conformity
All Declarations of Conformity can be found on www.endress.com.
CE Mark The WirelessHART Fieldgate SWG70 meets the legal requirements of the relevant EC direc-
tives. Endress+Hauser confirms successful testing of the WirelessHART Fieldgate SWG70 by
affixing to it the CE mark. An EC Declaration of Conformity has been issued for the Ex-versions and non-Ex versions of the device.
1.6 Technical improvement
Endress+Hauser reserves the right to make technical improvements to its software and
equipment at any time and without prior notification. Where such improvements have no
effect on the operation of the equipment, they are not documented. If the improvements

WirelessHART Fieldgate SWG70 Function and system design
3 Function and system design
3.1 WirelessHART protocol
The HART protocol has until now used the wired 4–20 mA loop with a superimposed digital
signal as physical layer.
WirelessHART enables the wireless transmission of HART data. To be employable worldwide, WirelessHART utilizes the 2.4 GHz Band (IEEE 802.15.4 wireless network) as physical
layer. The WirelessHART devices form a mesh network in which every device is not just a
measurement point, but also a repeater. This results in a wider range for the whole network
as well as increased reliability through redundant communication paths.
The network may comprise three types of device:
• WirelessHART gateway (Fieldgate SWG70)
• WirelessHART field devices
• WirelessHART Adapters (SWA70): either connected to 4–20 mA/HART devices or acting
as repeaters.
The WirelessHART network is built up, organized and maintained by the Fieldgate, which
also takes care for connection to different HOST systems through different bus interfaces.

3.2 WirelessHART network
Fieldgate SWG70 is the master device in the WirelessHART network. Acting as network
manager, it recognizes other devices wanting to join the network. It makes contact with each
in turn and initiates the procedures required for them to join. The network organizes itself
without any intervention on the part of the user. Fieldgate SWG70 also acts as security manager and collects the data sent by the network participants, converting it into a form which
can be used by other systems connected to it.
3.2.1 Network management
In its role as network manager, Fieldgate SWG70 organizes the wireless communication
between the WirelessHART field devices.
Fig. 3-2: Network management
1Step 1: Advertising
2Step 2: Join Request
3 Step 3: Authorization, Session & Network Keys,
Scheduling and Routing
4 WirelessHART gateway (Fieldgate SWG70)
5 WirelessHART device or adapter
After the Fieldgate has started up the network, devices can join. To this end, it first sends out
a call for devices to join the network. Then, the device sends a join request to announce its
wish to join the network. If the WirelessHART field device can identify itself with the same
network ID and join key as stored in the WirelessHART Fieldgate, the field device is authorized to join the network. Otherwise, the field device will be rejected.
In the next step, the WirelessHART Fieldgate sends session and network keys as well as
scheduling and routing information to the field device. The field device is told how to participate in the network and receives various information from the WirelessHART Fieldgate:
• Number and identity of neighboring WirelessHART field devices,
• When to send messages and which channels to use,
• When to repeat messages for other WirelessHART field devices,
• The optimal communication path for messages as well as alternative communication
paths in case of failure.
During this process, the WirelessHART device or adapter may also apply to send messages
in certain intervals and ask the network manager for the appropriate resources. The network
manager then takes care that these resources are available. For example, the network manager informs other WirelessHART field devices when to repeat messages.
3.2.2 WirelessHART security management
Fieldgate SWG70 also acts as security manager. To make communication safe, all messages
are encrypted with industry-standard AES-128 block ciphers with symmetric keys. Therefore, messages are unreadable for external listeners. The encryption keys are distributed by
the security manager.
The Join Key is used to join the network. Subsequently, the Join Key is automatically
exchanged against the Session Key and the Network Key, i.e. two new additional keys.

3.3 Connecting to HART-compatible host systems
Fieldgate SWG70 also makes wireless communication accessible to HART-capable host systems via its Ethernet interface or serial interfaces (RS-485) and the following functions.
Depending on the version ordered, Fieldgate SWG70 can also be integrated into Modbus,
OPC or Ethernet/IP host systems.
3.3.1 Instrument list
The WirelessHART devices in the network are made available to the host systems via an
instrument list. This list contains one or more I/O cards. Every I/O card has one or more
channels. Up to 6 field devices can be connected in multidrop mode to each channel. See
Figure 3-3 on page 13. The list itself can be up and downloaded. See Chapter 10.1 "Instrument List" on page 62.
Fieldgate SWG70 assigns a virtual I/O card to each WirelessHART device. The I/O cards are
assigned to the WirelessHART devices in the order in which they join the network. New
WirelessHART devices in the network are assigned to the next available I/O card, which is
added to the end of the instrument list (First-in-First-Out principle).
Within an I/O card, the WirelessHART device itself as well as status information is assigned
to Channel 0. If the WirelessHART device is an adapter, all field devices connected to it are
assigned to channel 1 (multi-drop mode). The list of the connected field devices is also called
sub-device list.
If a WirelessHART device loses communication to the Fieldgate, it stays assigned to the I/O
card initially allocated to it. When communication is established again, the device thus has
the same position in the instrument list that it had before.
The same principle applies to the field devices connected to the WirelessHART Adapter
(SWA70). When communication to the Fieldgate is lost, the long tags of the filed devices are
Fig. 3-3: Instrument list
stored. After communication has been established again, the field devices regain their previous position in the instrument list.

3.3.2 Cache
The WirelessHART Fieldgate stores information received over the WirelessHART network
and makes it available to the host for further processing. This ensures that information is
available immediately for the host system without having to send a request to the device and
wait for the response. The following commands and answers to requests are cached in the
Fieldgate.
Information cached in the
WirelessHART Fieldgate
Cache HART Command Description
Static: cached upon

1 Read Primary Variable
2 Read Current and Percentage
3 Read All Variables
9 Read Device Variables and Status
33 Read Device Variables
38 Read Additional Device Status
48 Reset Configuration Change Counter
93 Read Trend
Each listed command has its own cache memory. Static commands are stored in the cache
upon the first request. Dynamic variables are stored each time a field device sends a burst
message so that up-to-date values are available at all times.
With the exception of write commands 17, 18, 22 and 51, when the WirelessHART
Fieldgate receives a request from a host system which is embedded in Command 77, the
response is sent immediately (provided that the response is available in the cache).
Long Tag Emulation WirelessHART uses the long tag for addressing devices. Not every HART device supports
long tags, for example, older HART devices with HART Protocol Version 5 or less, do not support long tag addressing.
If a HART 5.0 device is connected to a WirelessHART Adapter (SWA70), the WirelessHART
Fieldgate emulates the long tag using the "Message" field. When a host system addresses a
HART 5 device, the emulation translates Command 20(22) directly into Command 12 (17)
which the HART 5 understands. The response is stored in the Fieldgate cache for CMD
12(17) and for CMD 20(22).

WirelessHART Fieldgate SWG70 Installation
4Installation
NOTICE!
• It is recommended that Fieldgate SWG70, adapters and devices be setup on the test bench
and the network be tested before the components are installed in the field.
4.1 Mounting considerations
4.1.1 Positioning the Fieldgate
Install the Fieldgate before installing other WirelessHART devices. This way you can check
for proper operation of new devices as they are installed. Nevertheless, consider the location
of future WirelessHART devices that will be routed through the Fieldgate to ensure good
connectivity.
Guidelines for Planning a
WirelessHART Network
• Mark the positions of the various measuring points on a scale overview of the plant. It is
important that the overview shows likely obstacles to the propagation of the radio waves.
• Make sure that a minimum of 2 other WirelessHART devices are well within the antenna
range of the device. If necessary, consider using an adapter as an additional stand-alone
repeater. Please refer to the following section for more information about the antenna
properties.
• Where a lot of metal, grids or walls prevent a device from being in line-of-sight of its
nearest neighbor, the maximum distance between two devices is 30 m. Install wireless
devices at least 1m above the ground or the floor.
• Where there are fewer structural elements and one or more neighbors are in direct lineof- sight, the maximum distance between two devices for planning purposes is 200 m. In
this case, install wireless devices at least 3m above the ground or the floor.
• Consider moving objects that could affect the device's antenna range.
• Make sure that the device's antenna is aligned vertically.
• If possible, position the Fieldgate at or near the center of the network - it should be in
contact with at least 20% of the devices in the network.
• Do not position WirelessHART devices directly below or above each other as they will be
outside each other's antenna range. See Chapter 4.1.3 "Examples of good and poor
positioning" on page 17.
• If possible, do not position the device next to metal surfaces, pipes or walls containing
metal (minimum distance: 6 centimeters). There should be as little metal around the
device as possible.
• Do not position other 2.4 GHz devices like cordless phone bases or WLAN routers near
WirelessHART devices. Wireless technologies used in an industrial environment must be
able to coexist without disrupting each other. If multiple networks operate in one facility,
wireless frequency management may be required.

4.1.2 Antenna range
The antenna supplied is an omni-directional dipole antenna.
A schematic representation of the wave propagation is provided in the following graphic.
If the antenna is pointed upwards, the signal is emitted horizontally. The transmission and
reception quality decreases by up to 50% as of an angle of approx. 39°. Almost no signal will
be radiated directly above and below the antenna.
We therefore recommend that you mount the wireless devices on one plane where possible.
If you must mount the wireless devices on very different planes, we recommend you use a
remote antenna. See Chapter 4.2 "Mounting the antenna" on page 17. Different coverage is
achieved with a remote antenna. For the associated requirements, please see the Technical
Information document for "WirelessHART Fieldgate SWG70" (TI00027S).

5.4 Connecting to RS-485
Fieldgate SWG70 is equipped with a fully galvanic isolated RS-485 interface. A second
RS-485 terminal block allows several Fieldgates to be connected through a daisy chain.
A terminating resistor is required at each end of the RS-485 cable. If the RS-485 cable is not
routed to other devices (no daisy-chain connection), activate the terminating resistor using
the corresponding DIP switches in the fieldgate. See Chapter 6.1.3 "DIP switches" on page 29.
NOTICE!
• The maximum length of the cable from the Fieldgate is 1200m (at reduced
communication speed).
• Use shielded twisted pair (STP) cables only.
• If the cable shield is grounded, only connect the grounding to one cable end. This avoids
potential equalization currents.
• Ensure adequate strain relief for the cables.
• Pay attention to the bending radii of the cables. Do not drop below the permitted bending
radii.

"DIP switches" on page 29.
7. Screw the housing cover on the housing.
8. Tighten the cable gland with appropriate torque. See Chapter 5.5 "Cable glands and
housing cover" on page 25.
5.5 Cable glands and housing cover
The degree of protection cannot be achieved if the cables and cable glands are not fitted
correctly.
To ensure the IP degree of protection
• all screws of the housing / housing cover must have been tightened with the appropriate
torque,
• only cables of the appropriate size must be used in the cable glands,
• all cable glands must be tightened with the appropriate torque,
• all seals must be undamaged and fitted correctly,
• all empty cable glands must be sealed with appropriate plugs.
The tightening torques of cable glands depend on what type of cable is used and must therefore be determined by the user. The cap nuts must be securely tightened. Tightening the cap
nuts too tight can have a negative effect on the protection class. The following figures can
be taken as rough guides.
Type of cable gland Approx. installation torque
Plastic 2.5 Nm
Nickel-plated brass 4.1 Nm
Stainless steel 4.1 Nm
The Fieldgate housing cover must be tightened with a torque of 2.5 Nm.

1. Enter a Global Advertising Timeout (1 ... 255 minutes)
2. Click the Activate Global Advertising button; advertising starts immediately.
8.2.2 Advanced Setup
Channel Blacklist With WirelessHART technology, Fieldgate SWG70 offers users a self-managed and self-
healing wireless network. If several wireless networks are being operated at one location,
the Fieldgate automatically selects the optimum channel assignment. If new networks are
added, the channel assignment is adapted automatically.
Alternatively, you can also configure the channel assignment manually. Note that a WLAN/
Wi-Fi channel based on the IEEE 802.11 standard is wider than a WirelessHART channel
based on the IEEE 802.15.4 standard. The numbering of the channels is different for
WLAN/Wi-Fi and WirelessHART.

10.3 Configuring Modbus
NOTICE!
• The "Modbus" function is only available on WirelessHART Fieldgate models with versions
"SWG70-xx-1-xx-xx" and "SWG70-xx-2-xx-xx". See Chapter 2.3 "Ordering information" on
page 10.
10.3.1 Modbus Settings
Modbus Settings determines how the Modbus information is to be transmitted by Fieldgate
SWG70 and where the information is to be found. It also allows the selection of automatic
or manual mapping. The set-up of the Modbus communication parameters (address, baudrate etc.) is described in Chapter 8.4.4.
More details on the Modbus Interface itself and the way in which the HART parameters are
mapped to the Modbus registers is to be found in. See Chapter 16 "Modbus Interface" on
page 118.

10.3.2 Input Status
Input Status allows the Modbus mapping of a device with single or multiple binary inputs.
As Fieldgate SWG70 supports extended registers, values are normally assigned to the registers with the reference addresses 100001 to 165536. The reference addresses are obtained
by adding the register number to 100,000. The dialog checks for completeness of entries
(line turns red if not correctly filled out) as well as double assignment to the registers (line
turns yellow).
The algorithm assumes that the discrete device delivers a maximum of 256 packed discrete
values, each comprising 16 bits of an unsigned Integer16 (UINT16). Each bit represents a
unique input status. Fieldgate first splits the data into two bytes. and reserves 8 registers for
each byte, i.e. one for each bit contained.
• Least significant byte (Bits 0 - 7) maps e.g. to registers 100001 - 100008
• Most significant byte (Bits 8 - 15) maps e.g. to registers 100009 - 100016
The value entered after the byte selection determines which of the packed discrete values is
to be mapped, e.g. 0 will map the first set of packed discrete values and 15 the sixteenth set
of packed discrete values. More information is to be found in Appendix 16.2.2.
NOTICE!
• Some HART devices map their binary values and status as PV in HART CMD 3. In this case
the value and status information will be found in the appropriate Input or Holding
Register. See Chapter 10.3.3 "Input Register" on page 73.
• If a device status is mapped as UINT8 in the input status register, the status will only be
found in one of the bit registers, e.g. in bit 0. The UINT8 is stored as a 16-bit value, the
MSB is populated with "0", see Appendix 16.1.3.

10.4.4 Configuring bursts using the WirelessHART OPC server
By using OPC technology, the WirelessHART OPC server offers the possibility of aligning the
burst rate with the WirelessHART Adapter SWA70 in accordance with the application
requirements. This means that no other program, for example FieldCare, is required for the
configuration.
Prerequisites The following prerequisites are necessary for burst configuration:
• The WirelessHART OPC server has been installed.
• The WirelessHART OPC server has been configured with the program "WirelessHART
Fieldgate OPC Configurator". The configuration file was saved with the menu item "Save
Active".
• The OPC client is connected to the WirelessHART OPC server.
• The link to the OPC server has been established in the WirelessHART OPC client. The
device tree structure created in the "WirelessHART Fieldgate OPC Configurator" appears:
Burst configuration The burst configuration is described and illustrated on the basis of the OPC client "OPC Data
Spy". Designations and procedures may differ for other OPC clients.

10.5 EtherNet/IP configuration
NOTICE!
• The "EtherNet/IP" function is only available on WirelessHART Fieldgate models with the
version "SWG70-xx-3". See Chapter 2.3 "Ordering information" on page 10.
The Fieldgate SWG70-xx-3 makes cyclic data available from up to 39 devices
(WirelessHART Adapters and field devices) via EtherNet/IP. In addition, data from Fieldgate
itself can also be made available via EtherNet/IP. Fieldgate offers 10 cyclic data exchange
connections for this purpose. Cyclic data from up to 4 devices can be exchanged via a data
exchange connection.
10.5.1 Setting up an EtherNet/IP connection
1. Set up the WirelessHART network. See Chapter 5.3 "Connecting to Ethernet" on
page 22. See Chapter 7.1 "Ethernet connection" on page 31.
2. Define the HART descriptors for all the HART and WirelessHART field devices that
should be monitored via EtherNet/IP according to the naming conventions. See
Chapter 10.5.2 "Assigning data exchange connections via HART descriptors" on
page 88.
3. Define the burst commands for all the HART and WirelessHART field devices that
should be monitored via the cyclic EtherNet/IP connection. See Chapter 10.5.3 "Burst
commands for cyclic data exchange" on page 89.
4. Integrate the WirelessHART Fieldgate SWG70 into your control system. For this
purpose, install the Add-On Profile (AOP) or the EDS file. See Chapter 10.5.4
"Integrating SWG70 into a PLC via EtherNet/IP" on page 90.
5. Make the configuration for cyclic or direct data exchange with the HART and
WirelessHART field devices. See Chapter 10.5.5 "Cyclic data exchange via the
ControlLogix® controller system" on page 90.
10.5.2 Assigning data exchange connections via HART descriptors
The "HART Descriptor" parameter is used to make available the cyclic data from field devices
and Fieldgates. You can configure this parameter in the corresponding DTM or DD.
The "HART Descriptor" parameter has the following structure for all field devices and for the
Fieldgates:
• Up to 13 characters of customized text
• Identifier with 3 characters.
The customized text is used to identify the devices in readable format. You can enter the tag
name here for example.
The identifier is used to assign the cyclic data and has the following structure:
• 1st character: @
• 2nd character: choice of one of the 10 cyclic data exchange connections. The letter "A"
corresponds to connection "1" and the letter "J" to connection "10".
• 3rd character: device identifier
The identifier @A0 is pre-assigned by Fieldgate and may not be used for WirelessHART
Adapters or field devices.

• FT101@A3
• TT101@B0
HART descriptors for adapters:
•ADAPTER1@B1
•ADAPTER2@B2
•ADAPTER3@B3
•ADAPTER4@C0
10.5.3 Burst commands for cyclic data exchange
In the case of WirelessHART, the variables from field devices and WirelessHART Adapters
are transmitted to the Fieldgate by burst commands. You must configure the burst
commands accordingly.
Use the DTM or DD of the corresponding WirelessHART device and flag the following burst
commands:
• Command 9: Read Device Variables with Status
• Command 48: Read Additional Status
As an alternative to command 9, you can flag command 3 "Read All Dynamic Variables and
Loop Current" or command 33 "Read Device Variables".
The following variables are available with HART commands 3, 9, 33 and 48:
Cyclic data variables In the HART command
393348
PV, SV, TV, QV x x x
PV Status, SV Status, TV Status, QV Status x
PV Unit, SV Unit, TV Unit, QV Unit x x x
Additional Device Status Information x
As an alternative to command 9, you can flag command 3 "Read All Dynamic Variables and
Loop Current" or command 33 "Read Device Variables".
Bit ".NoDataBurstConfigured" in "DeviceStatus_Struct" means that neither command 3, 9 nor
command 33 has been flagged. Bit ".NoDataBurstConfigured" in "DeviceStatus_Struct" means
that command 48 has not been flagged.
See Section "Data block of the WirelessHART Fieldgate" on page 95. See Section "Data block
of the HART devices" on page 97.

"Cmd48Data" is only invalid if ".NoCmd48BurstConfigured" is also flagged.
10.5.7 Diagnostic bits in cyclic data exchange
The cyclic data contain 4 error bits for every HART device. Each of these error bits can
suddenly appear during cyclic communication either when communication is lost or the
configuration of one or more devices has changed.
.HARTCommFail
This bit indicates that the device with the HART descriptor calculated from the cyclic
connection number and the data offset cannot be reached, does not respond or is still
initializing. The bit is reset as soon as the device is initialized. This bit is reset as soon as
the connection is lost.
.DescriptorNotUnique
The HART descriptors of all the devices in the WirelessHART network are read during the
basic device identification procedure. If EtherNet/IP discovers that more than two devices
share the same HART descriptor, the ".DescriptorNotUnique" bit is flagged in the cyclic data
exchange for the devices concerned. In addition, the ".DescriptorNotUnique" bit is also
flagged in the cyclic data exchange for WirelessHART itself to indicate that at least one
HART descriptor collision has been detected.
As devices with identical HART descriptors would share the same data offset in the same
cyclic connection, the cyclic data would be populated by random data from these devices. To
avoid this, the cyclic data are populated with the data of the device for which the identical
HART descriptor was first discovered. This prevents the loss of cyclic data if a new HART
device with an identical HART descriptor is added to the network.
98 Endress+Hauser

WirelessHART Fieldgate SWG70 Engineering
.NoDataBurstConfigured
This bit indicates that the device concerned has not been configured with burst command 3,
9 or 33. The missing burst configuration is either discovered during the detailed
initialization procedure or following a change to the configuration. Command 3, 9 or 33
must be flagged in order to publish cyclic data via EtherNet/IP.
Burst configuration of the wired devices must be performed via the bridge device. Burst
commands that are sent directly to the wired device are not recognized and cause the
".NoDataBurstConfigured" bit to be flagged.
.NoCmd48BurstConfigured
This bit indicates that the device concerned has not been configured with burst command
48. The missing burst configuration is either discovered during the detailed initialization
procedure or following a change to the configuration. Command 48 must be flagged in order
to publish cyclic data via EtherNet/IP.
Burst configuration of the wired devices must be performed via the bridge device. Burst
commands that are sent directly to the wired device are not recognized and cause the
".NoCmd48BurstConfigured" bit to be flagged.
Note that the ".NoCmd48BurstConfigured" bit remains active for devices that do not support
Command 48, such as HART devices Revision 5.
10.6 Downstream Communication (for discreet field devices)
You can use the Downstream Communication view to configure Downstream
Communication. With Downstream Communication, data are transmitted to discreet field
devices for control applications.
1. Click Engineering > Downstream Communication.
The following modes are available:
• On-change update mode
• Periodic update mode

Engineering WirelessHART Fieldgate SWG70
On-change update mode
By default, all Modbus output variables are updated with a change procedure. The Fieldgate
detects any change in the output status caused by the Modbus Master. The Fieldgate adds
the changes to a queue and transfers these changes to the discreet field devices as quickly as
possible.
Periodic update mode
The periodic update mode is activated by an update interval that is different to "00:00:00".
1. Click Engineering > Downstream Communication.
2. Enter the update interval in the Upload Period column for the relevant discreet field
device.
3. Click Apply. All specified variables are transferred periodically to the discreet field
device.
10.7 Substitution value (substitution value to DCS)
The WirelessHART Fieldgate detects when the last measured value is obsolete. This means
that the Global Age Threshold Warning limit or the Global Age Threshold Error limit is
exceeded.
In this case, you can specify one of the following substitution values:
•Last value
• NaN1 (0x7FE00000)
• NaN2 (0x7FA00000)
• Upscale (ffffff)
• Downscale (000000)
• User Defined
NOTICE!
• You can perform a Factory Acceptance Test with the substitution value. See
Chapter 10.7.2.
