Nodes may also be connected using a simplex network, but this is not a recommended practice. Other network configurations are possible, such as a combination of a star and cascade topology. DeltaV does not support network ring topologies. Refer to the latest DeltaV system installation and planning manual s for details of network layouts and network cable shielding requirements and power and grounding requirements for the overall DeltaV distributed control system DCS.

To be supported by Emerson, the DeltaV Control Network must be installed using the network equipment listed in this document. Wiring The maximum twisted-pair cable length for the DeltaV control network for any Ethernet-connected device is meters feet. If longer cable distances are needed for this workstation-to-switch, controller-to-switch, or switch- to-switch connections, there are various fiberoptic cable and transceiver solutions available from Emerson as a standard supported solution.

For special network designs that go beyond the supported diagrams shown in the DeltaV installation and planning manuals, consult with the Emerson services team. The DeltaV ACN supports the use of auto-negotiated half, half, full, and full duplex communications where the industry standard auto-negotiation process determines the highest speed at which two devices will communicate with each other.

The latest DeltaV network products make use of gigabit Ethernet for switch-to-switch communications and can support distances up to Km using standard product fiberoptic communications. The DeltaV workstations and controllers contain two Ethernet ports to provide the recommended redundant communications. Early models of DeltaV controllers supported 10 megabit Ethernet at half-duplex only.

The latest DeltaV controllers auto-negotiate to any speed and duplex from half to full, depending on what the controller is attached to. The workstations do the same: they auto-negotiate to the highest speed and duplex available from their attached device. Fiberoptic Wiring Because fiberoptic cables do not conduct electricity, they should be used in connections between buildings or in plant areas where electromagnetic interference is present.

Fiberoptic cabling should also be used where wire runs are longer than meters feet. DeltaV smart switches require no configuration to function in the DeltaV network. The Smart Switch will generate network, device, and security alarms to operator workstations. The built-in network and switch diagnostics provide network and switch diagnostic information to the Smart Switch Command Center without the use of third party SNMP applications. Local ports are connected to a single device such as a controller or workstation.

An uplink port is connected to another switch. The switch module contains the power supply and power and serial interface connections. The switch is composed of these two units and is available only as the complete switch unit.

The DeltaV Smart Switch provides a full family of built-for-purpose switches that are easy to use and provide advanced security features to help protect your DeltaV network from cyber incidents. Each media module has eight ports including copper, fiber, or SFP ports. This switch is not modular — the VE expansion modules are not used on this switch.

The VE transceivers can be used on this switch. Provided in VE One VE switch with terminal block for signal contact, two brackets with fastening screws pre-assembled , housing feet - stick-on, and power cable. Serial cable not include with product. Alarm Contacts. Front Panel LEDs. Redundant power connections. US power cables included with firewall. Rear access not required during operation. Or am I missing something here? Mark Millar.

Hi Rein, As far as I know this is unavoidable with a slave that is not talking. You have to remove the configuration from the VIM. We have found that if you leave this for a period of time, you will start to have comm issues and you will have to cycle power on the VIMs to recover them. I hope someone else knows something about this.
