TCP connection for Honeywell Universal Modbus

To connect controllers to the server The computer on which the Experion database software and server utilities run. See also: Experion server TPS. communicating using the Universal Modbus TCP Modbus is a serial communications protocol. protocol, you are required to have a network interface card Also known as: NIC. An expansion board inserted into a computer so that the computer can be connected to a network. Most NICs are designed for a particular type of network and media. See also: network. (NIC Network interface card. An expansion board inserted into a computer so that the computer can be connected to a network. Most NICs are designed for a particular type of network and media. See also: network.) connected to an Ethernet network on both the server as well as the controller Also known as remote terminal unit, RTU. A generic term for a device that is used to control and monitor one or more processes in field equipment. The most common control and monitoring device in an access control and security system is an access control panel. Other devices include security monitoring panels, elevator controllers, and fire monitoring devices. Controllers include programmable logic controllers (PLCs), loop controllers, bar code readers, and scientific analyzers. See also: C200 controller, control processor, CPM, hybrid controller, network node controller, PLC.. An external TCP/IP Transmission control protocol/internet protocol. A standard network protocol. bridge (Lantronix DR1-IAP) can also be used for RS-485 network connection to Ethernet.

C70 and C70R redundant communication and redundant controller architectures

The C70 and C70R models of the HC900 Hybrid controller. allow for redundant communication, and the C70R also allows for redundant controllers.

The following sections outline common architectures that involve these features. While a Backup Server is shown in each of these diagrams, the Backup Server is not required, and is included to show how a Backup Server would be connected if one existed.

Redundant controller

You are required to have a network interface card (NIC) on each server, and the E1 port on both controllers, connected to an Ethernet network via a switch A multiport device that moves Ethernet packets at full wire speed within a network. A switch may be connected to another switch in a network. See also: Ethernet, network..

Redundant controller and network

This is the same as the Redundant controller architecture, except that you require a second network adapter on each server, and the E2 port on both controllers, to be connected to a separate network (designated as LAN/WAN Wide area network. A general term to refer to a piece of a network and its components that are used to interconnect multiple LANs over a wide area. See also: LAN, network. #2 below) via a second switch.

LAN/WAN #2 must be configured as a different subnet Also known as link. A collection of nodes with unique addresses. See also: node..

Redundant controller on FTE

When connecting a HC900 to an FTE Fault Tolerant Ethernet is a Honeywell product that provides network redundancy using standard Ethernet hardware. It is the control network designed to provide not only fault-tolerance, but also the fast response, determinism, and security required for industrial control applications. See also: Ethernet, network, redundancy. network with redundant controllers, there must be two network connections on each server connected via FTE switches to the FTE network. The E1 port on the HC900s must be connected to the FTE Yellow switch.

The ports on the FTE switch must be configured to:

• Block A unit of data and operation within Experion. Experion uses blocks as the component from which control strategies are built. The two categories of blocks are hardware entities and functional entities. multicast and broadcast traffic

• Allow Auto-Detect or Half-Duplex (HC900 does not support Full Duplex communications)

Redundant controller and network on FTE

This is the same as the Redundant controller on FTE architecture, except that you require a third network adapter on each server, and the E2 port on both controllers, to be connected to a separate network (designated as Non-FTE LAN below) via a third switch.

Non-FTE LAN must be configured as a different subnet.
