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.

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.

Electronic Marshalling.

The “lock” command tells the switch to find all of the unused

network ports and disable them. It will also memorize what

devices are connected on each local port to prevent an existing

device from being replaced by an unauthorized rogue device.

Another single click will command all the switches to “unlock,”

to add a new device, or to troubleshoot any network problems.

The optional 60-minute relock timer will automatically relock all

of the switches to prevent the devices from accidentally being

left in the insecure, unlocked state.

The Command Center can be run from just the ProfessionalPlus

or can also be installed on operator or maintenance stations for

easy user access.

All locking and unlocking events are logged in the DeltaV Event

Journal so you can easily monitor unlocking events for unusual

activity and to be sure proper security procedures are being followed.

Auto Security Lockdown

The DeltaV Smart Switches contain auto lockdown security

technology to prevent unauthorized access to the network.

The DeltaV Network Device Command Center will automatically

locate all of the Smart Switches in the network and display

their locked or unlocked status. From the Command Center

a privileged user can lock or unlock all the switches in the

network with a single click. Or they can select a single

switch or set of switches to lock or unlock.

The Command Center can be run from just the ProfessionalPlus

or can also be installed on operator or maintenance stations for

easy user access.

All locking and unlocking events are logged in the DeltaV Event

Journal so you can easily monitor unlocking events for unusual

activity and to be sure proper security procedures are being followed.

Network Diagnostic Information The Network Device

Command Center provides detailed network statistics to

help in diagnosing network problems. Information is available

on a port-by-port basis so problem communications can

be easily isolated. The parameters most commonly used in

troubleshooting network issues such as dropped packets are

consolidated on a single display and the information needed

is right at your fingertips so troubleshooting the DeltaV network is easy.

Smart Switch Commissioning

Commissioning is done from a DeltaV workstation after the

switch is placed in service. Commissioning the switches after

they are installed creates the interface between DeltaV and

the switch that gains the full benefit of using the Smart Switch.

Commissioning allows the advanced switch setup parameters in

the switch to be preconfigured so they only have to be entered

once for the system. These parameters only have to be changed

if the default settings need to be modified.

Switch and Network Status Alerts

Using standard DeltaV device status reporting the DeltaV

Smart Switches will automatically repor t the status of both

the switch health and network communications problems.

Reporting items such as switch communications failure, switch

temperature, and power supply status. In addition the status

of network communications such as excessive packet collisions

or excessive dropped packets indicative of network problems

the DeltaV system provides all the network status information

without the use of third party SNMP applications.

Security Event Reporting DeltaV Smart Switches will report

security related events such as high network traffic that indicate

a denial of service attack is present and a port locking violation

that indicates an unauthorized device has been connected to

a “locked” switch port. Users are notified immediately that a

security event has occurred and can take actions to mitigate the attack.

Smart Switch Commissioning

Commissioning is done from a DeltaV workstation after the

switch is placed in service. Commissioning the switches after

they are installed creates the interface between DeltaV and

the switch that gains the full benefit of using the Smart Switch.

Commissioning allows the advanced switch setup parameters in

the switch to be preconfigured so they only have to be entered

once for the system. These parameters only have to be changed

if the default settings need to be modified.

Once the commissioning process assigns a network address

to the switch it will automatically begin reporting PlantWeb

alerts to the workstations. It also allows the Network Device

Command Center access to network diagnostics and the one

click lockdown security application. Integration into the DeltaV

system eliminates the pre-installation configuration and gets your

system back to full strength as quickly as possible.

The ability to commission and lock switches is limited to

the Can Configure, Can Calibrate, and Can Download user

privileges. Starting in DeltaV v13.3 the DeltaV Smart Switch can

be installed in the DeltaV 2.5 network or other DeltaV networks

external to the DeltaV control network. For the DeltaV Smart

Switch to be installed in a network the switch must be connected

to a DeltaV workstation (for example, Professional Plus) running

control modules.

DeltaV Plug-and-Play Installation

The DeltaV switches are easy to install in your DeltaV

network. Since they come preconfigured from the factory,

installation is as simple as mounting the unit, connecting the

communications cables, and powering up the unit. The switch

is configured to begin communications on power up — no

additional setup is required for the switching function to work

properly. This immediately returns the system to full redundancy

capability as quickly as possible with no time wasted configuring

the switch prior to installation.
