Section 1: Introduction
Section 1: 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 conguration 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 communicate with only one slave device (network master) for all data transfers to and from the
eld. 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 eld 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 setpoint, 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.

1.2 System Conguration
Controlinc Network Master Model M124 contains redundant valve actuator network masters in a
single enclosure. M124 supports one Controlinc E>Net ring network with up to 124 valve actuators.
The system uses standard RS485 and Modbus RTU protocol.
Redundant systems consist of two identical chassis with identical software. One is the primary master
and the other a hot standby master. The two chassis may switch roles of primary and hot standby at
any time. Figure 1 shows the specic system conguration of the supplied system. Version 1.0 and
later communicate with DCM 320B valve actuators with Version 1.0 or later rmware 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.
Each chassis consists of two Modbus Slave modules located in Slots 3 and 4. These slave modules
communicate with a redundant Modbus host systems up line. The CoProcessor installed in Slot 1 is
the Controlinc Network Master to a ring eld network. Two ports of the Network Master module are
connected to Network Interface Module (NIM) Model M124I with redundant, isolated ports. Each
NIM has connections to the redundant Network Master modules of the redundant chassis. Any one
of the four ports may acquire data from and control all actuators in the eld in either direction
around the network. Multiple M124 systems may be networked from a single host or redundant
hosts to automate any size system form a few valves to thousands of valves covering a large
network area. Ten (10) independent processors ensure full redundancy of all functions in a single
unit. All components except display are redundant with double-redundant host links to redundant
hosts and automatic processor hot swapping. Host equipment is not required to implement any
fail-over logic. Full-time redundant Modbus host links are standard. Plug-in modular construction
and DIN-rail mounting of components ensure minimum MTR, minimizing down time. LCD screen
and keypad provide valve actuator monitor and control of all valves in case redundant host links fail.
All valve status and alarms may be displayed by the LCD terminal for maintenance purposes.
The LCD terminal is a valuable troubleshooting tool during system commissioning. A more detailed
description of operation is provided in the Theory of Operation section of this manual.

Section 2: Installation
If the system is supplied from the factory in an NEMA enclosure, no internal wiring is required except
for connecting power and eld network wiring. The next three Sections 2.1, 2.2 and 2.3 discuss
mounting, power input and eld network wire connections to the NIM.
2.1 Mounting
The enclosure is rated for NEMA 4/12 and IP65/IP55. Dimensions of the enclosure are shown
in Figure 4. Mounting dimensions are shown in Figure 5. 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 ve 1/2" compression type
cable entry hubs. These may be tted with conduit type ttings if desired. If the system includes
backup LCD keypad terminal, some planning is required to allow for proper height above the oor to
view the display and properly operate the keypad.

2.1.1 Rack Mount
The enclosure is designed for standard EIA 19" DIN rail rack mounting. Dimensions of the
enclosure are shown in Figure 6. The enclosure conforms to EIA RS310, 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" (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 oor to view the display
and operate the keypad properly.

Section 2: Installation
2.2 Power Input
The system operates from 120 V AC or 220 V AC, 50/60 Hz single-phase power with internal
three-wire power terminals. Ensure that a good safety ground is provided to the electrical supply to
which the power input is connected. The system contains three main fuses (6.3x32 mm, 1 A) in the
DIN-rail mounted fuse blocks. Each chassis and the LCD terminal are independently fused. Each NIM
is powered from redundant 24 V DC power supplies from the two chassis power supplies. The LCD
terminal is powered from an independent 24 V DC power supply. All other modules within the unit
are powered over the base back plane from the associated main chassis power supply.
2.3 Field Network Wiring
The eld network is wired in a ring conguration from Port A around a loop to Port B of the
network master. Beginning at Port A, the network is wired to Port A of the rst actuator and then
from Port B of the rst actuator to Port A of the second actuator and so on until the network returns
from Port B of the last actuator to Port B of the network master. Networks may have parallel wired
(BUS wired) actuators between series wired actuators. Always wire parallel actuators to Port A
and remove termination and bias. Do not connect more than 15 actuators in parallel between any
two series connected actuators. Networks are polarized with (+) and (-) symbols on all drawings.
Proper operation requires that polarity be observed at all connections. Connect the eld networks
to the Port A and B connectors on the NIM in the network master as shown in Figure 8. The networks
must be connected to Port A and Port B of the valve actuators as shown in the wiring diagram
of the DCM 320B manual, and XTE manual. DCM 320B with Controlinc supports many different
network topologies. This manual supports only a single ring E>Net network topology that allows a
combination of parallel (BUS) and series E>Net connections on the same network.
