Network Master Mounting

If the system is supplied from the factory in an NEMA enclosure, no internal wiring

is required except for connecting power and field network wiring. The next three

sections (Sections 2.1. 2.2 and 2.3) discuss mounting, power input and field network

wire connections to the NIM.

Mounting of NEMA Enclosure

The enclosure is rated for NAMA 4/12 and IP65/IP55. Dimensions of the enclosure are shown

in Figure 5. Mounting dimensions are shown in Figure 6. The enclosure may be bulkhead

mounted using the internal mounting holes. External mounting brackets may be used if

desired. When mounting using the internal mounting holes, caution must be used to ensure

the holes are sealed to maintain the NEMA/IP rating. The enclosure is supplied with five 1/2 in.

compression type cable entry hubs. These may be fitted with conduit type fittings if desired.

If the system includes backup LCD keypad terminal, some planning is required to allow for

proper height above the floor to view the display and properly operate the keypad.

Mounting of Rack Mount Enclosure

The enclosure is designed for standard EIA 19 in. DIN rail rack mounting. Dimensions of the

enclosure are shown in Figure 7. The enclosure conforms to EIA RS-310. IEC 297-1. and DIN 41

494. Part 1 standards. The rack in which the enclosure(s) are mounted must allow a minimum

of 20 in. / 508 mm depth, allowing space for cable connections. If the system includes backup

LCD keypad terminals, some planning is required to allow for proper height above the floor to

view the display and operate the keypad properly.

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.
