System Configuration

Controlinc Network Master Model M250N contains redundant valve actuator network masters

in a single enclosure. M250N supports one Controlinc E>Net ring network with up to 250 valve

actuators. Options for support of redundant bus networks and redundant E>Net rings are also

available. The supplied system uses standard RS485 and Modbus RTU protocol for the valve

actuator networks. Ethernet TCP/IP encapsulated Modbus protocol connections are provided

for redundant host computer networks. The Ethernet links are IEEE 802.3 with RJ45 connectors

for 10/100Base-TX. Protocol is Ethernet v2 encapsulation TCP/IP Version 4.

Redundant systems consist of two identical chassis with identical software. One is the

primary master and the other a hot stand-by master. The two chassis may switch roles of

primary and hot stand-by at any time. Figure 1 shows the specific system configuration of

the supplied system. The network masters communicate with Controlinc valve actuators

that control both block valves (Open, Stop, Close) and modulating or positioner type valves.

The system consists of two six-slot chassis with each chassis having a central processor

located in Slot 0. which provides a global database for the CoProcessors installed the chassis.

The central processor also performs such functions as watchdog timers and system alarm

generation for the CoProcessors. It also provides interrupt control for fast data transfers

between processor modules. The main processor in each chassis supports a “Data Exchange

Link” (DxL) to share all data between redundant databases. See Figures 2 and 3 for internal

communication link connections.

The Network Master serves as a data concentrator for the host by providing a common

database for all slave devices. The host is required to communicatewith only one slave device

(network master) for all data transfers to and from the field.

Data can be transferred between the network master and host in large blocks at a much

higher communications rate than would be possible if the host communicated with each

slave device (valve actuator) on the field network. The Network Master acquires data from

the valve actuators by polling or scanning each device in a sequence of slave address from

a table called a scan list. Polling is a process of the Network Master sending to each slave

address, a command to return its status information, including alarms, discrete and analog

inputs and outputs. When control commands (valve open, stop, close, position set point, etc.)

are generated by a host system up-line of the Network Master, it then sends the appropriate

commands over the network to the addressed slave device. A more detailed functional

description of operation is provided in the Theory of Operation section of this manual.

Introduction

Emerson Controlinc Network Masters are the master of Emerson Controlinc valve

actuator networks with Modbus RTU protocol. The system provides network management,

data concentration and protocol conversion, off-loading the host system of these tasks.

This enhances overall system performance and minimizes software development and

system configuration tasks by the system integrator. The Network Master serves as the

master of a master/slave network. It manages the network by keeping an orderly

cycle of data transfers to and from the slave devices (valve actuators).

It handles error detection, alarming, and network recovery.

The Network Master serves as a data concentrator for the host by providing a common

database for all slave devices. The host is required to communicatewith only one slave device

(network master) for all data transfers to and from the field.

Product Description

The S-series IO subsystem has been redesigned with a focus

on fast assembly and simplified power connections. The system

uses only 24V DC bulk power supplies. All power is connected

to system carriers. Bus connectors have been upgraded to

support additional 12V DC power to the IO cards, allowing

additional power carriers to be inserted anywhere along

the bus.

Carriers mount to standard t-type DIN rail with latches that

require no tools for quick installation. The latches can be

released using a blade screw driver. Simply snap the carrier

to the rail and slide adjacent carriers together to engage the

bus connector.

The I/O carrier supports 8 IO modules. Each card can be

connected to an internal 24V DC bus using the Power Buss

Plugs, or it can be individually powered by using the

Power Terminal Plugs. The internal 24V DC bus is divided into

primary and secondary power, with primary power distributed

to odd numbered slots and redundant power distributed to

even numbered slots using the Power Buss Plugs.

Integrated power distribution. Controller and I/O interface

power distribution is integrated into the carriers to reduce and

simplify power and grounding. I/O Carriers have an integrated

shield ground bar to isolate and drain field noise away from

system power. They also provide an integrated redundant 24V

DC bussed field power distribution to reduce installation wiring

and provide fused, isolated power to each I/O interface, using

Power Buss Plugs. Alternatively, the I/O carriers can be ordered

with Power Terminal Plugs to bring dedicated power to each

card, which can be either 24V DC or 120/230V AC. Power Buss

Plugs and Power Terminal Plugs can be mixed on one

I/O Carrier.

A single Power Terminal Plug will come with any 120V AC DI

or 120/230V AC DO card.

Snap In Assembly. All components snap into place without the

use of special tools. The design supports and “easy on” design

to speed up installation and reduce maintenance turnaround.

Carriers snap onto T-DIN Rails. All interfaces and system power

supplies snap into place, eliminating retention screws.
