Connecting

All connections to the Gateway can be made at the terminal block, which is located in the lower junction box section of the enclosure. The terminal block label is located on the inside of the

lower cover. See Figure 3-6 for the standard terminal block label.

The junction box portion of the enclosure has four conduit entries for power and communications wiring. Do not run communication wiring in conduit or open trays with power wiring, or near heavy electrical equipment.

Install the included conduit plugs in any unused conduit openings. For NEMA

®

4X and IP65 requirements, use thread seal (PTFE) tape or paste on male threads to provide a watertight seal.

Grounding

The Gateway enclosure case should always be grounded in accordance with national and local electrical codes. The most effective grounding method is a direct connection to earth ground with minimal impedance. Ground the Gateway by connecting the external grounding lug to earth ground. The connection should be 1 Ω or less. The external ground lug is located below the Gateway enclosure and is identified by the following symbol:

3.4.2

Ethernet

The Gateway is equipped with two 10/100BaseTX Ethernet communications ports (see

Figure 3-6

). These connections can be used to access the Gateway’s web interface and to communicate Modbus TCP and OPC protocols.

The primary Ethernet port (Ethernet 1) is used to connect to the host system or other application systems. The secondary Ethernet port (Ethernet 2) can be used as a back up connection or a maintenance port for local access to the Gateway.

Ethernet connections should use Cat5E shielded cable to connect to an Ethernet hub, switch, or router. The maximum cable length should not exceed 328 ft. (100 m).

Note

Unless dual Ethernet ports were specified at the time of order, the secondary Ethernet port

(Ethernet 2) will not be active.

RS-485

The Gateway may be ordered with an optional RS-485 (serial) connection (

Figure 3-6 ). It is

referenced by the A and B Serial Modbus terminals. This connection is used to communicate

Modbus RTU on an RS-485 data bus.

Use 18 AWG single twisted shielded pair wiring to connect the Gateway to the RS-485 data bus.

The total bus length should not exceed 4000 ft. (1220 m). Connect the Tx + (positive, transmit) wire to terminal A and the Rx - (negative, receive) wire to terminal B. The wiring shield should be trimmed close and insulated from touching the Gateway enclosure or other terminations.

If the existing data bus uses a 4 wire Full Duplex configuration, see Figure 3-7

to convert to a

2-wire Half Duplex configuration.

Terminating resistors

Three DIP switches are provided to enable various terminating resistors to the RS-485 data bus.

The switches are found inside the electronics housing near the top center of the main circuit

board ( Figure 3-8

).

Figure 3-8. RS-485 Resistor DIP Switches

470Ω Pull-down Resistor Main Circuit Board

120Ω Terminating Resistor

Electronics

470Ω Pull-up Resistor

Switches 1 and 3 are connected to pull-up and pull down resistors. Switch 1 is for the Tx + (A) line and Switch 3 is for the Rx – (B) line. These 470 Ù resistors are used to prevent noise from being interpreted as valid communications during periods when no actual communications are occurring. Only one set of pull-up and pull-down resistors should be active on the RS-485 data bus at time.

Switch 2 is connected to a 120 Ω terminating resistor. This resistor is used to dampen signal reflections on long cable runs. RS-485 specifications indicate that the data bus should be terminated at both ends (

Figure 3-9 ). However termination should only be used with high data

rates (above 115 kbps) and long cable runs.

Power

The Gateway is designed to be powered by 24 VDC (nominal) and requires 250 mA of current.

The positive and negative connections are found on the left side of the terminal block

(

Figure 3-6

). An additional case ground is found on the left side of the junction box enclosure.

Connect supply power to the positive + and negative – power terminals found on the left side of the terminal block (

Figure 3-6 ). Recommended torque is 7 in-lbs and the gauge is 12 to 22 AWG.

An additional internal case ground can be found on the left side of the enclosure. The wiring should include an external power shut-off switch or circuit breaker that is located near the

Gateway.

Note

Using an uninterruptible power supply (UPS) is recommended to ensure availability should there be a loss of power.

Security Setup Utility

The Security Setup Utility enables secure communications between the Gateway and host system, asset management software, data historians, or other applications. This is done by encrypting the standard data protocols (AMS Wireless Configurator, Modbus TCP, Ethernet/IP ™ , and OPC) used by the Gateway and making them available through various proxies within the

Security Setup Utility. These proxies can function as a data server for other applications on the control network. The Security Setup Utility can support multiple Gateways at once and each proxy can support multiple client application connects.

Overview

This section describes how to connect the Gateway to a host system and integrate data gathered from the field device network. It covers network architectures, security, and data mapping.

In accordance with Emerson WirelessHART ® security guidelines, the Emerson Gateway should be connected to the host system via a LAN (Local Area Network) and not a WAN (Wide Area

Network).

Network architecture

Physical connection types are important when determining the network architecture and what protocols can be used for integration. Ethernet is the primary physical connection type and

RS-485 is available an optional connection type. The following network architecture diagrams will help when integrating data from the Gateway into the host system.

Ethernet

An Ethernet connection supports Modbus ® TCP, OPC, AMS ® Wireless Configurator,

Ethernet/IP ™ , and HART ® TCP protocols. Using this connection type, the Gateway is wired directly to a control network (see

Figure 5-1 ) using a network switch, router, or hub. There are

often two networks for redundancy purposes.

Fiber optic (optional)

A Fiber optic connection supports Modbus TCP, OPC, AMS Wireless Configurator, and HART TCP protocols. Using this connection type, the Gateway is wired to a fiber optic switch (see

Figure 5-2

).

Note

A fiber optic connection requires a third party copper Ethernet to fiber optic Ethernet converter.

RS-485 (serial)

An RS-485 connection supports Modbus RTU protocol. Using this connection type, the Gateway is wired to an RS-485 bus which typically leads to a serial I/O card or Modbus I/O card (see

Figure 5-3

). Up to 31 Gateways can be connected to a single I/O card in this manner.

Modbus

The Gateway supports both Modbus RTU over the RS-485 serial port and Modbus TCP over

Ethernet. It functions as a sub device on the Modbus network and must be polled by a Modbus master or client (host system).

Communication settings

It is import that the Modbus communication settings in the Gateway match the setting in the

Modbus master or client. Please refer to host system documentation for more information on how to configure these settings. The Modbus communication settings can be found by navigating to System Settings>Protocols>Modbus.

Figure 5-5. Modbus Communications Page

36

One Modbus Address: When this option is selected, this address is used by the Gateway for

Modbus RTU communications.

Multiple Modbus Addresses: When this option is selected, a new column for address will appear on the Modbus mapping page.

Modbus TCP Port: This is the TCP/IP port the Gateway uses for Modbus TCP (Ethernet). To change TCP/IP port settings, see the Internal Firewall section for more details.

Host Integration

Baud Rate: The data rate or speed of serial communications. This setting is only required for

Modbus RTU.

Parity: This setting determines parity (none, even, or odd) to use for error checking purposes.

This setting is only required for Modbus RTU.

Stop Bits: This setting determines the number (1 or 2) of stop bits to use when ending a message. This setting is only required for Modbus RTU.

Response delay time (ms): This setting determines how long (ms) the Gateway waits before responding to a Modbus request. This setting is only required for Modbus RTU.

Unmapped register read response?: This is the value returned by the Gateway if the Modbus master requests a register with no data assigned to it (empty register). It is recommended this be set to zero fill to prevent errors.

Floating point representation: This setting determines if the Gateway uses floating point values or integer values. There are three options for this setting.







Float uses 32 bit floating point values.

Round rounds the data value to the nearest whole number.

Scaled uses scaled integers to offset negative values or increase decimal point resolution. The equation for scaled integers is: y = Ax - (B - 32768)

Where: y = Scaled integer returned by the Gateway

A = Gain for scaled integer value x = Measured value from wireless field device

B = Offset for scaled integer value

Use swapped floating point format?: This setting switches which register is sent first for a floating point value. This setting is only used for floating point values.

Incorporate value’s associated status as error?: This setting will cause the Gateway to report a predetermined value when a communications or critical diagnostic error is received from the wireless field device. The value is user configurable depending on which floating point representation is chosen. See Value reported for error below.

Value reported for error (floating point): This setting determines what value is reported if the wireless field device reports a failure or stops communicating to the Gateway. This setting is used for floating point values. The choices are NaN (not a number), +Inf (positive infinity), -Inf

(negative infinity), or Other (user specified).

Value reported for error (rounded and native integer): This setting determines what value is reported if the wireless field device reports a failure or stops communicating to the Gateway.

This setting is used for rounded or scaled integers. The choice is a user specified value between

-32768 and 65535.

Scaled floating point maximum integer value: This determines the maximum integer value for the purpose scaling integers. 999-65534

37


January 2015

5.4.2


00809-0200-4420, Rev HB

Use global scale gain and offset?: This setting determines if a global gain and offset is applied for scaled integers or if each value has a unique gain and offset. Unique gain and offsets are found on the Modbus Mapping page.

Global scale gain: This value is multiplied to the data values for the purpose of scaling integers.

If global scaling is not selected, a gain value will be available for each separate data value on the

Modbus Mapping page.

Global scale offset: This value is added to the data values for the purpose of scaling integers. If global scaling is not selected, an offset value will be available for each separate data value on the

Modbus Mapping page.

Register mapping

Register Mapping is the process of assigning data points from wireless field devices to Modbus registers. These registers can then be read by a Modbus master or client. Modbus register mapping can be found by navigating to System Settings>Protocols>Modbus.

When changes have been accepted, select Return to form.

Address: This is the Modbus RTU address used by the Gateway for this data point. It is possible to group data points assigning them the same address (i.e. all data points from the same process unit can have the same address). This column only appears if Multiple Modbus Addresses is selected on the Modbus Communications page.

Register: This is the Modbus register number used for this data value. Modbus registers hold two bytes (16 bits) of information; therefore 32 bit floats and integers require two Modbus registers. Each data point needs a unique Modbus register number, unless they are assigned different addresses. Register numbers 0-19999 are reserved for Boolean (bit, coil, binary, etc…) values. Register numbers 20000+ are reserved for floating point or integer values.

Point Name: This is a two part name for the data point. The first part is the HART Tag of the wireless field device which is producing the data. The second part is the parameter of the wireless field device.

Note

Point Name is entered as <HART Tag.PARAMETER>. Point Name can be entered using the list of values (…) or manually entered. The following table gives a list of standard device parameters which may be considered for Modbus register mapping.

00809-0200-4420, Rev HB

Note

The **_HEALTHY parameters are a great indication of the health and communications status of the data values.

State (state value): The value of a data point which drives a Modbus output of 1. For example, if a data point is reported as either True or False, a state value of True will report a 1 for True and 0 for False. A state of False will report a 0 for True and a 1 for False. State is only required for register numbers 0-19999 (Boolean, bit, coil, binary, etc…).

Invert: This check box will invert the Modbus output from a 1 to a 0 or a 0 to a 1. Invert is only used for Boolean values using register numbers 0-19999.

Gain: This value is multiplied to the data value for the purpose of scaling integers. Gain is only required if scaled is chosen on the Modbus communications page and globe gain and offset is not chosen.

Offset: This value is added to the data value for the purpose of scaling integers. Offset is only required if scaled is chosen on the Modbus communications page and globe gain and offset is not chosen.

Overview

Native integration with DeltaV enables the Smart Wireless Gateway to be autosensed and easily commissioned for seamless integration with all DeltaV applications: Explorer, Diagnostics, and

Control Studio. WirelessHART ® devices can be easily added to the wireless field network and then reconciled through DeltaV Explorer and assigned to analog channels through drag and drop assignment.

Latency considerations in control logic design and operation

Since the DeltaV wireless I/O scanner software requests updates for 1/5 of the devices each second, DeltaV receives updates on a particular field device once every 5 seconds. That is not necessarily synchronized with the update rate of the field device. Also, there is some latency between when the field device takes a process sample and when it is permitted to pass its value onto the wireless network. Status update responses can also increase latency in some instances.

So for example, if a device updates once every 8 seconds, and wireless network latency is 2 seconds, the amount of time that could pass between when an event occurred in the field and before it is available to the DeltaV I/O bus is between zero and 15 (8+2+5) seconds. The update period of the DeltaV control module should be added to that total to determine the range of latencies before an event in the field can be acted upon by the control system.

Operators should be made aware that the update rate of wireless measurements on operator screens are somewhat slower than those from wired devices. For example, if the operator initiates a valve movement, it can be 5-15 seconds before confirming feedback appears on the operator screen. Any control logic designed along the same principles should also take the update rates and latencies into account as well.

Overview

Redundancy for the Smart Wireless Gateway increases the availability of the wireless field network by providing two sets of physical hardware which operate as a single Gateway system.

This section covers setup and installation of a redundant Gateway system. It also covers diagnostics and integration to help monitor the health of the redundant Gateway system.

Choose one Gateway as the starter Gateway. For the purposes of this document, it will be referred to as Gateway A. The other Gateway will be referred to as Gateway B.

To configure redundancy system settings:

1.

Connect a PC/laptop to the Ethernet 1 port on Gateway A.

Log in using the admin user account.

Navigate to System Settings>Gateway>Redundancy.

Gateway A’s factory serial number will be assigned to Gateway A.

Gateway B’s factory serial number will be assigned to Gateway B.

The Gateway names will be used in diagnostic messages and host system integration to help identify each Gateway. It is recommended that these names be marked on each physical

Gateway, in addition to the configuration settings.

Selecting left or right for Gateway A is for visualization purposes only. It has no effect on performance or functionality.

After the redundancy system settings have been configured, the two Gateways must be connected and undergo a pairing process.

To pair both Gateways and form a redundant system:

1.

Connect a PC/laptop to the primary Ethernet port on Gateway A.

Log in using the admin user account.

Navigate to Diagnostics>Advanced>Redundancy Status.

Connect the secondary Ethernet port on Gateway A to the secondary Ethernet port on

Gateway B (see Figure D-3 on page 70 , Redundancy Setup Connections

).

A dialog will appear on the page; select Form redundant pair.

Wait for the Pairing to redundant peer status to turn green.

Select Return to page.

Once the Gateways have finished the pairing process, Gateway A will appear as the current active Gateway on the left hand side and Gateway B will be the standby Gateway on the right

(note that left/right hand appearance can be changed on the Redundancy System Settings page). If significant configuration changes need to be downloaded to the standby Gateway, it may temporarily go offline shortly after the pair process is complete. This is expected behavior and does not represent instability in the system.

Mounting and connections

Redundant Gateways follow similar mounting and connection practices as a standalone

Gateway. Please refer to Section 3: Mounting and Connection for more information. In addition to the standard practices, the following considerations should be taken when installing redundant Gateways.

Mounting

The redundant Gateways should be mounted in a location that allows convenient access to the process control network as well and provides good coverage for the wireless field network.

The redundant Gateway antennas should be mounted at the same height and be spaced between 3 ft to 9 ft (1m to 3m) horizontally. This is to ensure that they provide identical coverage for the wireless field network and to help eliminate coverage gap in the event of a switch over.

Ethernet

An Ethernet connection to the host system will support Modbus TCP, OPC, AMS ® Wireless

Configurator, and HART IP protocols. When using this architecture, connect the secondary

70

Ethernet port on Gateway A directly to the secondary Ethernet port on Gateway B. Then connect the primary Ethernet ports for both Gateways to a process control network using sepa-

rate/redundant network switches. See Figure D-4

Ethernet Connection Architecture.

Note

The primary Ethernet port for each Gateway should be connected to separate network switches on the same process control network. Consult a control system administrator for more details about available redundant network switches.

Simplex RS-485

A simplex RS-485 host connection supports Modbus RTU protocol. When using this architecture, connect the secondary Ethernet port on Gateway A directly to the secondary

Ethernet port on Gateway B. Then wire the RS-485 ports for both Gateways in parallel to a single

serial card at the host system. See Figure D-5

Simplex RS-485 Architecture.

Note

In either a simplex or dual RS-485 architecture, the primary Ethernet ports can be connected to an asset management network to provide connectivity to AMS Device Manager or AMS Wireless

Configurator.

Dual RS-485

A Dual RS-485 host connection support Modbus RTU protocol. When using this architecture, connect the secondary Ethernet port on Gateway A directly to the secondary Ethernet port on

Gateway B. Then wire the RS-485 ports for both Gateways separately to dual serial cards at the host system. See

Figure D-6 Dual RS-485 Architecture.

Note

By default, only the active Gateway in a redundant system will respond to Modbus polling requests. If simultaneous polling is desired, login to the Gateway web interface, navigate to

Setup>Modbus>Communications and set “Respond when running as redundant standby?” to

Yes. Only use this setting in a dual RS-485 architecture.

Power

Power for the redundant Gateways should be applied after all primary and secondary Ethernet and RS-485 connections have been made. Using separate uninterruptable power supplies (UPS) is recommended to ensure availability of the redundant Gateway system.

Diagnostics

The redundant system will perform many diagnostic checks to verify the health and connectivity of the system.

Figure D-7. Redundancy Status (Diagnostics>Advanced>Redundancy Status)

These diagnostics can also be mapped to Modbus registers or OPC tags. The following table covers what diagnostics are included on the Redundancy Status page as well as how they can be mapped as parameters in Modbus or OPC.

In addition to the redundancy diagnostics, an additional check may be configured to test network connectivity to a host system or other application. The redundant system will use this check to determine the best connectivity option and which Gateway should be set to the active

Gateway.

To configure network connectivity check:

1.

Navigate to System Settings>Gateway>Ethernet Communication.

Enter the host system IP address in the Check Network Connectivity IP Address field.

Select Save Changes.

Gateway replacement

When replacing or reintroducing a Gateway in a redundant system, always connect both the primary and secondary Ethernet connections before powering the standby Gateway. If the

Gateway is being reintroduced (i.e. it was a part of the original redundant system), it will automatically rejoin the redundant system. If the Gateway is new or has been set to default configuration, it will need to be paired to the current active Gateway. Navigate to System Set-

tings>Gateway>Redundancy and follow the recommended actions on that page or follow the procedure above to pair Gateways and form a redundant system.
