Power over Ethernet

This Gateway is equipped with PoE technology to allow it to source power to a compatible device over the connecting Ethernet cable (PSE mode) or derive its power from another PoE device via the Ethernet connection (PD mode). This device complies with the IEEE 802.3at-2009 standard for PSE operation and IEEE 802.3af-2003 or IEEE 802.3at -2009 for PD operation. These standards require the use of Category 5 Ethernet cable or higher.

In the operation of IEEE 802.3a, PoE power is only transmitted from one device to another when the proper impedance match is made. This prevents damage to non PoE devices on the network. In the Gateway, power is transmitted in passive mode over two unused differential pairs of the Ethernet cable. To use this feature, the Gateway must be connected over the Ethernet to a matching IEEE 802.3a device. Failure to do this will cause no power to be sent or sourced.

A set of switches on the power supply board allow the selection of the specific Ethernet port for PoE and the selection of whether it is a PSE (Power Sourcing Equipment) sourcing power or a PD (Powered Device) deriving its power from another IEEE 802.9 PSE device. See Figure 2-3 for the switch diagram required for PoE configuration.

Note

The Gateway can either source or receive power over an Ethernet port; it cannot do both at the same time.

If using the Gateway as a PSE, the total additional power requirements of the PD must be factored into the total input power requirements of the power supply for the Gateway. It is recommended that the power selection mode switch be left in the PD position unless PSE is needed.

Note

Only one port and one mode of operation (PD or PSE) can be selected at a time; any other combination of jumpers is invalid.

Note

IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) to each device. Only 12.95 W is assured to be available at the powered device as some power is dissipated in the cable.

IEEE 802.3at-2009 PoE standard also known as “PoE+” or “PoE plus”, provides up to 25.5 W of power. The 2009 standard prohibits a powered device from using all four pairs for power.

For more information on PoE and frequently asked questions, refer to Emerson Wireless 1420 Gateway with Power over Ethernet Technical Note

or “Power over Ethernet (PoE)” on page 21.

In order to use both ports for PoE, remember to order option code “2” when selecting number of Ethernet ports.

Time settings

Configuration

July 2017

The Gateway is the timekeeper for the WirelessHART network, so it is imperative that the Gateway’s time is accurate for timestamp data to be meaningful. Time settings can be found by navigating to System Settings>Gateway>Time.

There are three ways to set the Gateway time:

 Network Time Protocol (recommended)

– This option uses a Network Time Protocol (NTP) server to adjust the Gateway’s time in order to

match the time of the control network. Enter the IP address for the NTP server and select the packet version (1, 2, 3, or 4).

 Set with PC Time

– This option will match the Gateway’s time to that of the PC/laptop.

 Manual Entry

– This option allows the user to enter a specific date (MM:DD:YY) and time (HH:MM:SS).

Note

Network Time Protocol (NTP) is recommended for the best network performance because it always adjusts time to match the network time server.

3.4 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 requirements, use thread seal (PTFE) tape or paste on male threads to provide a watertight seal.

3.4.1 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 1Ω or less. The external ground plug is located below the Gateway enclosure and is identified by the following symbol:

3.4.2 Ethernet

4X and IP65

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.

3.4.3 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.

Installation

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. Only terminated at one end typically at the power supply end.

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 Ω 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 3-10). However termination should only be used with high data rates (above 115 kbps) and long cable runs.

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.

Note

When using PoE PD, a power supply is not required.

3.4.6 Power over Ethernet (PoE)

The new Gateway hardware supports IEEE 802.3af and IEEE 802.3at PoE.

With the growth of Ethernet, many have wanted to save time and cost on wiring by sending power down to an Ethernet device over the same Ethernet cable used to haul data. This is possible because there are four extra wires in an Ethernet cable that are typically not used. In the past there was no formal standard, people came up with their own wiring schemes for using these wires to provide power. This resulted in a number of different schemes to exist and lead to confusion as people were damaging their computers because they did not know there was power available over the Ethernet cable.

Installation

Page 30

Installation

July 2017

Reference Manual

00809-0200-4420, Rev HD

In 2003, IEEE 802.3af standard for PoE was adopted. It specified:

 The wires that would carry power and how  Devices that could source power and devices that could be powered  Supplied wattage would be up to 15 Watts (in 2009, IEEE 802.3at was adopted, which allowed power

up to 25 Watts)

 The voltage used  A method of protecting against damaging non-PoE devices

There are two types of IEEE 802.3 PoE devices

1. PSE (Power Sourcing Equipment) is a device that acts as a voltage source and supplies PoE to devices via the Ethernet cable.

2. PD (Powered Device) is a device that is supplied with power via PoE from a PSE device via the Ethernet cable.

The Gateway can be configured by jumpers to work in either one of the modes referenced above. Therefore the Gateway can source power or be powered via the Ethernet cable.

Note

The Gateway cannot be a PSE and a PD at the same time. PoE can only be configured on one Gateway port at a time.

PoE advantages

To save costs on planning, wiring and installation of networks, devices are supplied with power directly via the Ethernet cable (e.g. via a Cat 5/5e cable up to 100m). PoE makes the network planning flexible, independent of power supply cabinets, and junction boxes. There are no extra costs for the electrical wiring. An advantage of PoE is that you can install devices with an Ethernet interface in places of difficult access or in areas in which running cable would be inconvenient. This in turn saves installation time and costs. This technology is in use today typically in IP telephones, cameras, or wireless transmission devices such as WLAN Access Points.

An excellent application is a Gateway connected to a Wi-Fi back haul unit; such as a Cisco

or ProSoft® unit. For example a Cisco unit could power the Gateway or in another case the Gateway could power the ProSoft unit as in a PFN with the addition of an external power supply.

Selecting devices to work with a PoE Gateway

The connecting device to the Gateway whether it is a PSE or a PD must be labeled as compliant with IEEE

802.3af or IEEE 802.3at. Many companies use labels on their packaging such as PoE for IEEE 802.3af or PoE+ for IEEE 802.3at. Check the specific manufacturer's specifications of any device to make sure somewhere it references IEEE 802.3; otherwise it may not work.

The Gateway works as either a PoE PSE for IEEE 802.3af (sourcing 15 Watts) or PoE+ PSE for IEEE 802.3at (sourcing 25 Watts) depending on the input voltage to the Gateway from the power supply. For 12 VDC nominal input, the Gateway can source 15 Watts. For 24 VDC nominal input, the Gateway can source up to 25 Watts. No additional adjustment is necessary.

In the PoE PD mode, the Gateway draws its power over the selected Ethernet cable from another PoE IEEE

802.3 device either 802.3af or 802.3at.

Caution is needed in selecting a companion device to the Gateway for PoE. Not all devices labeled PoE will function. Before 2003, there was no standard and companies developed their own techniques for powering over an Ethernet cable. These techniques are not always interoperable. Before the standard,

Installation

Page 31

Reference Manual

00809-0200-4420, Rev HD

they used the term PoE on many of their products. Most new products labeled PoE are IEEE compatible. Cisco products can be ordered with their old standard (Online Power as it is sometimes referred to) or with the IEEE 802.3 PoE standard. Check with the appropriate manufacturer if in doubt before purchasing/installing the connecting equipment.

For reference, Cisco offers the following four versions:

1. Prestandard PoE (Online Power)

2. 802.3af-compliant PoE (15W)

3. 802.3at-compliant PoE Plus (PoE+) (25W)

Universal PoE (UPoE) (60W). (New Cisco standard, which Cisco claims is compatible with IEEE 802.3af PoE and IEEE 802.3at PoE +)

Note

When using a Gateway as IEEE 802.3 PSE device, check the total power levels of all the PD equipment connected (including the Gateway itself 3.6 Watts) to make sure the power supply to the gateway can source enough power. It is always a good design practice to make sure the power supply has more than enough power capability to handle startup loads and future expansion.

IEEE 802.3 PoE gives protection from damaging a computer or another piece of equipment

When using IEEE 802.3 PoE, one of the important new features of this standard is that PSE devices have a test mechanism to protect connected incompatible devices from being damaged. Only devices which have an authenticating characteristic based on the IEEE 802.3 standard, receive power via the Ethernet cable. To determine whether a PD is connected, the input parameters are checked by the PSE. This method is called “Resistive Power Discovery”. During the discovery process resistance, capacitance, and current are checked.

If the PSE detects a PD it starts classification, i.e. determination of the power requirement of the connected device. For this the PSE applies a small defined voltage to the power input of the PD's and measures the resulting current. The PD is assigned to a power class based on the value of the current. Only now the total voltage is supplied to the power input.

This sophisticated system prevents computers and other devices from being damaged when connected to these cables.

Older non-IEEE standard PoE offerings may not have this protection and could damage computers and other devices.

Proper PoE installation considerations

Installation

In all electrical installations, local codes and prevailing regulations must be observed. Only use properly trained/licensed installers, approved materials, have installations inspected as required and if in doubt seek help from a qualified person. PoE+ and the load of the Gateway (approximately 3 to 4 Watts) can add up to 30 Watts of power; because of this the proper Ethernet cable must be selected depending on the length of the cable run. Check with the manufacturer for the specifications of the cable being used to determine the power versus length requirements. Multiple powered Ethernet cables running in the same location must be considered for total temperature rise. Most Ethernet cable suppliers have charts for PoE usage on their websites.

Typically, Cat 5 should handle most installations with runs up to 100 meters (approximately 300 feet). The use of Cat 3 is not recommended in any installation PoE or non-PoE, Cat 3 may work for some lower power short run applications, but overall it has poorer data handling and lower power capability. Cat 6 and Cat 7 are respectively better than Cat 5.

PoE FAQs

Does the old 1420 Gateway hardware have PoE?

No, not IEEE PoE; in the current 1420 Gateway there is a third Ethernet port on the far left of the connector board (closest to the hinge). This port has a cover on it; in the manual it is labeled “Ethernet 2 with Power.” This connector is connected to Ethernet port 2 and the spare Ethernet wires in this connector are bridged to the input power lines to the Gateway. This was designed for special applications and is not recommended for normal use. This connector can damage computer and other equipment connected to it if used improperly and has been removed as it is not needed in the new PoE design.

What do I have to do to order IEEE PoE on a 1420 Gateway?

There is no specific option code for PoE. In time, all 1420 Gateways will have PoE. Initially PoE will be offered by approvals codes as PoE is approved for that application. For example, typically N5 or N6 approvals take the least time. These approvals codes when approved for PoE would automatically ship with the new hardware. Approval codes like N3 or N4, which typically take a longer time, would ship with PoE at a later date. Contact your Emerson Sales Representative to find out if a particular code has been approved for PoE.

It should be also noted that all PoE units shipped are configured as a PoE PD on port 1. By using the jumpers included with the unit, the installer configures the unit during installation as to mode and port of PoE operation if desired. See the “Gateway PoE jumpering” on page 26 for jumpering diagrams.

If I am not using PoE, how should I program the Gateway?

Program the 1420 Gateway as a PoE PD on either port; then connect up the local power supply (24 or 12 VDC) to the power input terminals of the Gateway. There is no problem if the Gateway is programed as a PD and has local power too. The Gateway working as a PD when it sees local power switches to the local power instead of the Ethernet PoE. See “Gateway PoE jumpering” on page 26 for jumpering diagrams.

What type of power supply should I use with the PoE Gateway in the PSE mode?

A Class 1 power supply is strongly recommended for all Gateway applications for improved safety. The power supply should be a 24 or 12 VDC unit. 24 VDC allows more power to be sourced in the PSE mode. The power supply should be able to handle at least 30 Watts if using PSE; for good operating margin it would be advisable to consider at least a 50 Watt supply.

Note

Solar or battery power is not recommended for PoE PSE operation as there are additional power loses caused by the PoE circuitry.

What is the maximum Voltage PoE PSE can source?

Maximum Voltage is normally 48 VDC; up to 25 Watts.

Can you do redundant power with PoE?

Yes, as PoE becomes more popular many network appliance (switch) providers are supplying innovative switches and other hardware to create redundantly powered networks. Typically, many switch suppliers offer switches that allow multiple power inputs. Check your local switch supplier as to available configurations. Also, the Gateway will work with a local power supply connected to the power input terminals of the Gateway and as a PD with power coming over the Ethernet at the same time. If both sources are present, the Gateway selects the local power supply first. If the local power fails, the Gateway automatically switches to Ethernet power. When the local power is restored, the Gateway automatically returns to local power.

How do I know if my 1420 Gateway has IEEE PoE capability?

The simplest way to check for IEEE PoE capability is to open the upper door on the 1420 Gateway and the see how the computer board is mounted. In the newer hardware, the board is mounted horizontally. The

old hardware the computer board was mounted vertically.

5.2 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 as an optional connection type. The following network architecture diagrams will help when integrating data from the Gateway into the host system.

5.2.1 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 <HotXRef>Figure 5-1) using a network switch, router, or hub. There are often two networks for redundancy purposes.

5.3 Internal firewall

The Gateway supports an internal firewall that inspects both incoming and outgoing data packets. TCP ports for communication protocols are user configurable, including user specified port numbers and the ability to disable ports.

The Gateway’s internal firewall settings can be found by navigating to System Settings>Protocols> Protocols and Ports.

Figure 5-4. Security Protocols Page (Internal Firewall)

Reference Manual

00809-0200-4420, Rev HD

5.4 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).

5.4.1 Communication settings

It is import that the Modbus communication settings in the Gateway match the setting in the Modbus master or client. 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.

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.

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:

Operation and Maintenance

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).

Reference Manual

00809-0200-4420, Rev HD

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

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.

5.4.2 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.

To add a new data point to the Modbus register map:

1. Select Add New entry.

2. Complete all of the table entries for the new data point (note that the entry columns may vary based

on the Modbus communications settings).

3. Repeat for each new data point.

4. Select Submit.

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.

Reference Manual

00809-0200-4420, Rev HD

RELIABILITY and ONLINE relate to wireless communications. RELIABILITY is the percentage of messages received from the wireless field device. ONLINE is a true/false indication of whether the device is communicating on the wireless network.

**_HEALTHY parameters are a true/false indication of the health of a particular variable (** = dynamic variable – PV, SV, etc…). These parameters incorporate critical diagnostics from the wireless field device as well as communication status.

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.

Reference Manual

00809-0200-4420, Rev HD

C.2 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 five 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 eight seconds, and wireless network latency is two 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 five to 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.

D.3 Setup

When configuring redundant Gateways, it is only necessary to configure one system. The other Gateway will be configured automatically when it is paired with the first Gateway.

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.

2. Log in using the admin user account.

3. 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.

Figure D-2. Redundancy Status

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.

2. Log in using the admin user account.

3. Navigate to Diagnostics>Advanced>Redundancy Status.

4. Connect the secondary Ethernet port on Gateway A to the secondary Ethernet port on Gateway B (see Figure D-3 on page 74, Redundancy Setup Connections).

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

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

7. 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.

D.4 Mounting and connections

Redundant Gateways follow similar mounting and connection practices as a standalone Gateway. Refer to Section 3: Installation for more information. In addition to the standard practices, the following considerations should be taken when installing redundant Gateways.

D.4.1 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 3–9 ft. (1–3 m) 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.

D.4.2 Ethernet

An Ethernet connection to the host system will support Modbus TCP, OPC, AMS™ Wireless Configurator, and HART-IP

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 separate/redundant network switches. See Figure D-4 Ethernet Connection Architecture.

D.4.3 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.

D.4.4 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.

D. Dual serial card E. RS-485 bus F. Se condar y E th erne t

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.

D.4.5 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.

Redundancy

Page 86

Reference Manual

00809-0200-4420, Rev HD

D.5 Diagnostics

The redundant system will perform many diagnostic checks to verify the health and connectivity of the system. In the event of a failure, it can take up to 30 seconds for the Gateway to trade positions.

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

Redundancy

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.

Table D-1. Redundancy Diagnostics

Parameter Description Data type

REDUNDANT_HEALTHY Overall redundancy status indicating the system is ready for a switch-over Boolean

RF_COVERAGE_FAILURE Check to verify that both Gateways have the same RF coverage of the wireless field

REDUNDANT_A_ONLINE Operational status of Gateway A Boolean

REDUNDANT_A_MASTER Indication if Gateway A is the active system Boolean

REDUNDANT_A_PING Indication if Gateway A is able to ping designated host IP address Boolean

REDUNDANT_A_ETH0 Electrical connection status of the primary Ethernet port for Gateway A 8-bit unsigned int

REDUNDANT_B_ONLINE Operational status of Gateway B Boolean

REDUNDANT_B_MASTER Indication if Gateway B is the active system Boolean

REDUNDANT_B_PING Indication if Gateway B is able to ping designated host IP address Boolean

REDUNDANT_B_ETH0 Electrical connection status of the primary Ethernet port for Gateway A 8-bit unsigned int

Boolean

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.

D.6 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 Settings>Gateway>Redundancy and follow the recommended actions on that page or follow the procedure above to pair Gateways and form a redundant system.
