Configuration	Reference Manual
July 2017	00809-0200-4420, Rev HD

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.

DIS: Disabled; this disables the PSE operation

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

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.

3.4Connecting

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.

3.4.1Grounding

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:

3.4.2Ethernet

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

Note

Unless dual Ethernet ports were specified at the time of order, the secondary Ethernet port (Ethernet 2) will not be active.

3.4.3RS-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. Only terminated at one end typically at the power supply end.
