The DeltaV Smart Switches are preconfigured for use exclusively

within the DeltaV control network or the networks listed in

Table 1 above. All switch configuration is performed using

the DeltaV Network Device Command Center [for DeltaV

10.3 configuration is only done through the DeltaV Setup

Wizard using the serial port Command Line Interface]. These

configuration interfaces provide very limited access to switch

configuration parameters. General administrator access to the

DeltaV Smart Switches is disabled to prevent possible mis

configuration of the switch that would impact DeltaV network

performance. A list of the available configuration parameters is

listed in the DeltaV Setup Parameter section

of these specifications.

In DeltaV v13.3 and later the DeltaV Smart Switches can be

installed in the DeltaV 2.5 network or other DeltaV networks

external to the DeltaV control network (see Table 1). For

the DeltaV Smart Switches to be installed in a network, the

switches must be connected to a DeltaV workstation running

control modules. It can be installed in the DeltaV virtualization

networks only if the network is accessible to a DeltaV

workstation (virtual or physical) running control modules.

Product Specifications

The DeltaV Smart Switches is based on hardware produced

by a recognized supplier of industrial-grade networking

equipment. All switches are fan-less and have redundant

power connections. Same models are also available in high

temperature, conformal coated versions for use in harsh

environments. The firmware features are identical in all models

of the DeltaV Smart Switch.

In DeltaV v13.3 and later the DeltaV Smart Switches can be

installed in the DeltaV 2.5 network or other DeltaV networks

external to the DeltaV control network (see Table 1). For

the DeltaV Smart Switches to be installed in a network, the

switches must be connected to a DeltaV workstation running

control modules. It can be installed in the DeltaV virtualization

networks only if the network is accessible to a DeltaV

workstation (virtual or physical) running control modules.

These specific control modules are required to run the DeltaV

Network Device Command Center application. DeltaV Operator

Workstations are not capable of running these control modules.

Use outside of the DeltaV Control Network

The DeltaV Smart Switches is supported only as an unmanaged

switch if installed in networks outside of the DeltaV control

network, the DeltaV 2.5 network between the DeltaV

workstations and the perimeter firewall (such as the Emerson

Smart Firewall), or other DeltaV networks external to the DeltaV

control network. The switch will only accept a management

port network address from the DeltaV Network Device

Command Center and the switch can only be used where this

application is able to access the switch.

The DeltaV Smart Switches is not available for use as a managed

switch in the DeltaV InterZone network as the DeltaV Network

Device Command Center cannot access the switch if located on this network.

Compatible with previous versions of

DeltaV systems

Switches are compatible with existing systems that are

installed using only our supported Cisco or Hirschmann

switches. Fiber communications of the Smart Switch will

only communicate at 100/1000MB full duplex (not

configurable) and wired ports will only auto-negotiate

communications (setting is not user adjustable).

Existing switches must be configured to run either in auto

negotiate mode or 100/1000MB full duplex communications.

Existing 3COM switches and media converters may not be

compatible with the DeltaV Smart Switch as they may not

support the required communications. The Smart Switch

will not plug and play in some older networks unless the

existing devices are set to match the specifications above

during the installation.

The auto switch lockdown is compatible only with DeltaV v10.3

and later revisions.

switch in the DeltaV InterZone network as the DeltaV Network

Device Command Center cannot access the switch if located on this network.

Compatible with non-DeltaV Switches

The DeltaV Smart Switch also can be installed in a new system

mixed with the currently supported and shipping Cisco or

Hirschmann switches.

Please read DeltaV Books-on-line for important information

when retrofiting into existing DeltaV networks, especially in

systems with existing 3COM switches or media converters.

Fiberoptic connections on DeltaV Smart Switches are non

configurable and communicate only at 100Mbps on the DeltaV

ACN or 1Gbps switch-to-switch at full duplex.

Installing DeltaV Smart Switches into systems with existing

fiberoptic devices that are not set to 100/1000Mbps full duplex

will cause communications disruptions in the network.

Network Loop protection – spanning tree protocol is

implemented on the Smart Switch to prevent a network loop

from creating a network communication storm.

These storm protection features are enabled by default and

cannot be disabled or configured. Storm protection is enabled

even if the switch is not given an IP address for management.

These features are completely compatible with older DeltaV

Smart Switches. Existing switches can be field upgraded to use

these new features if desired.

Please see the general specifications section for specific

firmware version numbers.

Important note: Network storm protection and loop

protection are available only on managed switches. Therefore,

DeltaV control networks using Electronic Marshalling require a

Smart Switch installed between the DeltaV controller and CIOC.

This network configuration reduces the risk of a network storm

disrupting communications and causing the CIOC to go to a

fail-safe mode.

Please refer to DeltaV Books-On-Line and the v13.3 System

Planning Guide for more information and requirements for

implementing the DeltaV Area Control Network with

Electronic Marshalling.

System Compatibility

Network Storm Protection Features

Packet rate limiting – the Smart Switch is configured with

a fixed rate packet limiting setting. The switch rate limiting

prevents network communication storms generated from

broadcast, multicast, and unknown unicast messages from

impacting DeltaV communications by blocking excessive

traffic. These types of excess traffic can occur naturally as part

of the traffic generated by Ethernet communications. Storm

protection is enabled to protect the network during system

maintenance activities, redundancy switchovers, and during

times when the system is performing routine network activities

where excess network traffic is possible.

Important note: Network storm protection and loop

protection are available only on managed switches. Therefore,

DeltaV control networks using Electronic Marshalling require a

Smart Switch installed between the DeltaV controller and CIOC.

This network configuration reduces the risk of a network storm

disrupting communications and causing the CIOC to go to a

fail-safe mode.
