Safety	WirelessHART Fieldgate SWG70

1 Safety

1.1Designated 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.

1.2Installation, 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.

6	Endress+Hauser

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			WirelessHART networks use the frequency spectrum between 2400 ... 2483.5 MHz accord-
technologies			ing 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 with-
			out 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.
Operation			CAUTION!
			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-ver-
			sions 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 effect operation, a new version of the operating instructions is normally issued.

WirelessHART Fieldgate SWG70	Function and system design

3 Function and system design

3.1WirelessHART 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.

Function and system design	WirelessHART Fieldgate SWG70

3.2WirelessHART 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.

3.2.1Network management

In its role as network manager, Fieldgate SWG70 organizes the wireless communication between the WirelessHART field devices.

														3
													Fig. 3-2: Network management
1	Step 1: Advertising										4			WirelessHART gateway (Fieldgate SWG70)
2	Step 2: Join Request										5			WirelessHART device or adapter

3Step 3: Authorization, Session & Network Keys, Scheduling and Routing

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.

3.2.2WirelessHART 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.

WirelessHART Fieldgate SWG70	Function and system design

3.3Connecting 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.

3.3.1Instrument 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.

Fig. 3-3: Instrument 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 stored. After communication has been established again, the field devices regain their previous position in the instrument list.

3.3.2Cache

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	Cache	HART Command	Description
WirelessHART Fieldgate
	Static: cached upon	0, 11, 21	Read unique identifier (associated with tag or long tag)
	read
	Static: cached upon	12, (17)	Read (Write) Message
	read & write
		13, (18)	Read (Write) Short Tag, Descriptor, Date

		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 sup-
	port 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

4 Installation

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.

4.1Mounting considerations

4.1.1Positioning 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	• Mark the positions of the various measuring points on a scale overview of the plant. It is
WirelessHART Network	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 line-
	ofsight, 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.

4.1.2Antenna 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).

5.4Connecting 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.

5.For a daisy-chain connection, route the second RS-485 cable through the second cable gland from left and connect it to the right terminal block labeled "RS-485", see table above.

6.To activate the RS-485 termination, set DIP switch number 7 to "ON". See Chapter 6.1.3 "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.

5.5Cable 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.
