1.3 BASIC HARDWARE

1.3.1 MOD 30ML MULTILOOP CONTROLLER

The 1800R, Figure 1-1, is designed for mounting in a panel with a 15.75-inch depth. The
instrument housing contains a termination facility accepting all instrument I/O,
communications, and power connections. This assembly is designed to allow termination
signal entry from either top or bottom, allowing for flexibility in signal separation for wiring
considerations. The instrument connects to the terminals via an edge connector at the back
of the carrier board, permitting interchangeability without disconnecting field wiring.

The 1801R has a narrowed display bezel for installations where horizontal spacing is an
issue.

The 1803R split-architecture model allows the display to be remotely mounted (up to 8 ft/243
cm) from the remainder of the controller.

The carrier board provides the connection locations for the modular I/O. There are eleven
locations for single width I/O modules. Ten of the locations are arranged in pairs to accept as
many as five double-width modules. The carrier board also contains the built-in I/O and
communications circuits. Two direct connected analog inputs accept thermocouple, RTD,
millivolt and volt dc, milliamp dc and resistance inputs. A 24V dc transmitter power supply for
2-wire transmitters is available on both inputs. Two outputs provide either a 20 mA dc signal
or a 50 mA dc signal. The built-in communications circuits terminate in five multi-purpose
terminals permitting connection to any of the following networks: ICN, RS-232 Modbus, and
2-wire or 4-wire RS-485 Modbus.

MOD 30ML Multiloop Controller

PRODUCT DESCRIPTION

The instrument CPU is a 16MHZ 68302 microprocessor. An identity module (1800P)
provides the functionality that gives the instrument the capability to execute a user-configured
database. The CPU supports 64K bytes of nonvolatile RAM for database storage, and a
time-of-day clock with battery support. A high speed communications channel is used
between the CPU and both the built-in I/O and any I/O modules installed on the instrument.
The CPU board provides for connection of an optional plug-in memory module.

1.3.6 2010P Portable Memory Module

The optional memory module plugs directly into the CPU board, Figure 1-1, and
provides a mechanism for porting a database from one instrument to another.
An instrument with this option can upload from or download to this module. The
memory module has a write protect setting to prevent accidental erasures.
When a memory module is installed in an instrument with the write protection
off, the operating software keeps the module up-to-date with all real time
changes in the instrument. Enhanced security is thereby provided through this
backup database copy. Data retention is typically 10 years with instrument
unpowered.

configuration. Input to the module is scaled and then applied to an integrating analog to
digital converter. Line cycle integration can be performed at either 50 or 60 Hz line
frequencies to reject any line frequency noise. Transformer isolation from the +5 volt supply
is used to derive all the internal voltages to run the isolated front end. Optical isolation is
used to transfer the information from the A/D converter serially to the microprocessor. The
microprocessor takes the raw A/D voltage, compares it to the reference, and then presents it
to the host as requested over the serial communications bus. This module uses the
Voltage/Current Input Module (VCIM) Block for configuration of input parameters.

MECHANICAL INSTALLATION

2.1 GENERAL

Read these instructions thoroughly before starting installation. Installation personnel should
be qualified technicians.

Mechanical installation involves:

 Unpacking (Section 2.2)

 Planning and Installing optional I/O and memory modules if these items are being used

(Section 2.3)

 Mounting (Section 2.4)

2.1.1 Displays and Cleaning

The display is protected by an overlay that can be removed after installation. The face of the
display, while made of scratch-resistant plastic, can be abraded by harsh materials such as
paper towels and industrial wipes. Lens cleaning tissues and soft cloths are suitable for
cleaning displays. Remove dust from the rear of the instrument by removing it from the
instrument housing and spraying exposed surfaces with non-corrosive, non-toxic, non­flammable inert dusting gas.

2.1.2 Environmental Specifications

Storage Temperature: –40 and+75°C (–40 and 167°F)
Humidity 5 to 95 % RH, non condensing
Altitude: 2000 meters max
Ingress Protection: Options 0,1,2 Front: IP22 Rear: IP20
Option3 (NEMA 4) Front: IP56 Rear: IP20
Pollution degree: 2

2.2 UNPACKING

Unpack and visually inspect the instrument housing, controller, and associated modules for
any damage. The instrument may be removed from its housing, if necessary, to install
modules or change the communication jumper. Remove the controller from its housing by
loosening the retaining screw(s) in the front panel and pulling the unit out of the housing.
Save packing materials for any reshipment, or to support any claim of shipment damage. All
damage claims are made against the carrier and are the responsibility of the customer.

Included in the shipping container is a bag containing mounting brackets and screws, and an
information package. A card containing several copies of a writeable instrument identification
tag is included in the information package. Write required data on the tag and insert it under
the translucent strip at the bottom of the front panel after the controller is installed.

2.3 INSTALLING MODULES

The controller can accommodate as many as eleven I/O modules. These optional plug-in
modules expand the built-in I/O capacity of the controller. An optional memory module is
also available. The I/O modules mount on the carrier board, and the memory module mounts
on the CPU board as shown in Figure 1-1. The modules must be installed before placing the
controller into operation.

2.3.1 I/O Module Planning

In general, there is a high degree of flexibility in locating the I/O modules. The only specific
location restrictions are as follows:

 Field I/O circuits for locations S7 through S11 must not operate at voltages above 30V

rms, 42.4V peak, or 60V dc to comply with safety approval/certification requirements.

 Communications modules have a dedicated location determined by the communications

port being used.

 Special attention should be given to the 2003A current output and the 2012A active

current input modules to ensure adequate air flow for heat dissipation. It is
recommended they be installed in a slot that has no module in either adjacent slot, or in
slot 11 as long as slot 10 is not a 2003A or a 2012A. If installing these modules without
recommended spacing, it may be necessary to install fans in the cabinet or panel to
maintain temperatures below the maximum ambient operating limit. Refer to the
Mounting section of this manual for details.

 To guarantee the accuracy of the built-in cold junction compensator, when used, there

should be no module in slots 1 or 2 and no 2003A or 2012A in slots 3, 4 or 11.

Table 2-1 lists the available I/O module types, their associated data base memory block
identifications, and the valid locations for each module type. An I/O planning form is provided
to document the planned I/O configuration. An example of the form, listing built-in I/O
assignments and the module layout for a controller with five I/O modules, is shown in Figure
2-1. See Appendix A for a blank copy of all planning forms.

WARNING Do not use any I/O module which is not listed in Table 2-1. When used

in MOD 30ML systems, the listed modules are FM Approved and CSA
Certified for use in Class I, Division 2, Group A, B, C or D hazardous
(classified) locations. Substitution of a module not on the list voids the
Approval/Certification.

Some other factors which influence I/O module requirements are as follows:

 If the controller requires thermocouple inputs, the first thermocouple should be connected

to built-in input 1 to provide automatic cold junction compensation for all inputs. If
automatic cold junction compensation is not enabled, an I/O module must be installed to
provide the compensation. See Section 4.3.1 for more information.

 The layout of module locations on the carrier board, Figure 2-1, divides locations 1

through 10 into pairs allowing double-wide modules to occupy only five different
locations.

 Communications port 1 serves either the built-in communications circuits or module

location S10 (S10 and S9 if module is double-wide). If the communications function is
being used, connections should first be made to the built-in communication circuit. This
leaves module locations S9 and S10 available for other I/O functions. Location S8 (S8
and S7 if module is double-wide) is always available for communications via port 2. See
Section 5 for more information.

MOD 30ML Multiloop Controller

MECHANICAL INSTALLATION

WARNING Do not use a 2011A Mechanical Relay Output Module when the

installation environment contains chemicals which can degrade the
materials used to seal the relay in the module. The sealing materials are
as follows:

 Polybutylene Terephthalate, Polyplastics Co. Ltd., Compound No.

3270

 Polyphelene Suffide, Summitomo Chemical Co. Ltd., Compound No.

3601GL30

 Epoxy Resin, Summito Bakelite Co. Ltd., SUMIMAC ECR-9107K

Degradation of the relay seal voids the Approval/Certification of the
instrument for use in Class I, Division 2, Group A, B, C or D hazardous
(classified) locations.

The controller power supply has the capacity to handle the base instrument load of 1220 mA
plus any mix of built-in and modular I/O loads such that the total current consumption does
not exceed 5000 milliamps (5 amps). Add the current consumption for the base instrument,
built-in I/O, and each I/O module using the planning form in Appendix A, Verify that the total
does not exceed 5000 milliamps.

2.3.2 I/O Module and Memory Module Installation Procedure

Install the modules as follows:

1. Loosen the retaining screw(s) in the front panel, Figure 1-1, and pull the instrument out of

its housing.

! CAUTION: Support the instrument from the front and bottom whenever the

instrument is outside its housing. Do not allow the full weight of the circuit
boards to be suspended unsupported from the front panel as this may
overstress the brackets at that end.

2. Place the instrument on a flat surface with the front panel overhanging the edge of the

surface so that the circuit board is firmly supported. This positioning assures that the
instrument is not damaged by the force applied when inserting I/O modules.

3. Plug each I/O module into its required location on the carrier board and tighten the

retaining screw.

4. Use the memory module as described in IB-1800-OPR Operation/Setup Manual.

* NOTE: When installing the memory module it is important to orient it so that the

catalog number label is visible when the module is plugged into the
connector on the CPU board.

2.4 MOUNTING

The controller must be installed in an approved enclosure or installed in a means acceptable
to the authority having jurisdiction for electrical installations.

WARNING Do not install a MOD 30ML controller in a residential, commercial or light

Select a mounting location where:

 There is minimum vibration.

 The ambient temperature is between 32 and 122°F (0 and 50°C) with a relative humidity

of 5-95% RH (noncondensing). The ambient temperature and humidity requirements
apply to the air directly below the controller.

 The installation allows for free air flow above and below the controller

 If it is necessary to mount two or more controllers above each other, and the room

ambient temperature is above 70°F, heat generated by the lower instruments may raise
the ambient of the upper instruments above the 122°F limit. To assure that operating
temperatures are within specified limits, it is recommended that a fan be installed below
the instruments to force air circulation over the instruments in an upward direction. Air
velocity should be at least 100 to 200 feet per minute.

industrial environment in the European Union.

 The panel provides rigid support for a fully loaded 5.5-pound (2.5 kg) controller and any

other panel devices.

 Electrical wiring routing and support are planned.

Mount the controller as follows:

1. Prepare the panel as indicated in Figure 2-2. Be sure to allow enough clearance under

the front panel of each controller to access the communications jack in the bottom of the
front panel (not present with NEMA 4 option).

2. Draw a 1/4" boundary around cutout for reference when caulking. Apply a 1/4“ bead of

silicon caulking (Loctite # 59530 or equivalent) on the panel around the cutout.

* NOTE: If NEMA 4 is not required, the controller can be installed without the gasket or the

caulking.

3. Slide instrument housing only into panel cutout.

4. Insert brackets into slots in top and bottom of instrument housing.

Be sure the housing gasket is not pinched or twisted between the instrument housing

and the front of the panel.

5. Tighten retaining screws to a torque of 5 inch-pounds (0.6 Nm) or 1-1/2 turns after

contact is made with the back of the panel.

6. Wipe the excess silicon caulking to form a smooth fill and allow it to dry for 24 hours.

7. After the caulking has dried, insert the instrument into the housing and tighten the jack

screw(s) to 7 to 10 inch-pounds (0.8 to 1.1 Nm) or 1-1/2 turns after the front face draws
into the gasket (two screws for NEMA 4 option, one on top otherwise).

POWER, GROUNDING, AND BUILT-IN I/O CONNECTIONS

3.1 GENERAL

Read this section thoroughly before making any connections. Installation personnel should
be qualified technicians. Observe all electrical code requirements and safety standards
applicable to these wiring procedures.

Specific instructions and connection diagrams for the various built-in inputs and outputs are
provided in Sections 3.3 through 3.6. A listing of the applicable electrical specifications is
included in each section.

3.2 CONNECTION GUIDELINES

The wiring connections described in this section are made with the controller installed in its
operating location and with the power off. All connection terminals are on the back of the
instrument housing. See Figure 3-1a for Model C and Figure 3-1b for Models A & B. On
Models A & B the terminals are located under a cover. Figure 3-1b shows the cover removed.

! CAUTION For Models A and B, do not connect any wires to terminals 23, 24,

48, and 49. Connections to these terminals can cause an
instrument malfunction. This does not apply to Model C.

The recommended procedure for making power, grounding, and built-in I/O connections is as
follows:

1. Make a copy of the wiring planning sheet, Appendix A, and list each wire connection. It
is recommended that the planning sheet be used to plan and document all wiring
connections: power, grounding, built-in I/O, modular I/O, and communications.
Connection instructions for modular I/O and communications are provided in Sections 4
and 5.

2. The power wire size must be from 14 AWG (1.6 mm) to 18 AWG (1.0 mm) with a 600V,

-20°C +105°C UL, CSA approved rating.

3. The signal wire size can be as small as 22 AWG (0.65 mm). All analog input wiring must
be shielded twisted pairs. Shields must be connected to a good noise free ground (the
chassis ground terminal at the upper right hand corner of the housing is recommended).
See Section 3.4.4 for more information.

4. Route signal wiring less than 30 V rms, 42.4 V peak or 60 V dc from top left. Route signal
wiring greater than 30 V rms, 42.4 V peak or 60 V dc from bottom right. Distribute to
appropriate terminals.

on t

6. Strip approximately 5/16 inch (8 mm) of insulation from the end of each wire, insert wires

at assigned terminals and secure terminal screws and clamps.

7. Make wiring connections using the following procedures:

a. Power connections - Section 3.3.

b. Ground and shield connections - Section 3.4.

c. Built-in process input connections for various types of inputs - Section 3.5

d. Built-in output connections - Section 3.6

8. After all connections are completed and checked, do the following:

a. If modular I/O and communications are required, follow the procedures in Sections 4

and 5.

b. If all connections are completed, the ac power wiring can be connected at the

distribution panel (ac source).

NOTE: Before putting the controller into operation, it must be configured using either the
front panel keys or the PC configuration Software. See Section 1.1.2 for related documents.

Instrument Common (terminal 25) should not be left floating. Tie it to chassis or a separate
instrument ground if available.

36

3.3 POWER CONNECTIONS

 WARNING Avoid electrical shock. AC power wiring must not be connected at the

distribution panel (ac source) until all wiring procedures are completed.

All power wiring must be in compliance with the requirements of the National Electrical Code
or Canadian Electrical Code. In any installation where the power source does not have one
side of the line connected as a neutral conductor, both sides of the line must be overcurrent
protected.

The controller does not contain a power disconnect switch. Install a disconnect switch or
circuit breaker between the controller and its power source. Choose an accessible location
as near to the controller as practical, and identify the switch or breaker as the disconnecting
device for the controller.

The ac power connections are made to the power terminals shown in Figure 3-1 Route
power cable from the bottom right hand side of the housing.

Power specifications for the controller are:
Power Supply Input:

Instrument Power Code 1: 85 to 250 V rms, 50 to 400 Hz
Instrument Power Code 0: 20 to 50 Vdc (
Power Consumption (120V rms, 60 Hz): 50 VA maximum
Transient Overvoltages: Classified as Installation (Overvoltage) Category II
per IEC 664 (Specifies a maximum impulse withstand voltage of 1500 V for phase to

earth voltage of 150 Vrms)
Interruption: No effect from 2-cycle dropout at 120V rms, 60 Hz.
Interference: No permanent effect from exposure to IEC 801-4 fast transients
level 3, or IEC 801-5 surges level 3.

POWER, GROUNDING, AND BUILT-IN I/O CONNECTIONS

3.4 GROUND CONNECTIONS

On Model C instruments, connect ground terminal on the lower right side (Fig 3-1a) directly to
the plant safety ground system. On Models A & B, a protective ground terminal (green metal
stud) is provided at the bottom of the terminal blocks near the power connections (Figure 3­1b). Connect this terminal directly to the plant safety ground system. This terminal is to be
used only for the protective ground conductor. Keep the ground wire as short as possible and
use the largest practical wire gage.

3.4.1 Chassis and Shield Grounds

Model C controllers have a chassis terminal on the upper right of the termination (Figure 3­1a). Model A and B controllers have chassis terminals on the upper and lower right of the
termination (Figure 3-1b). The protective ground connects directly to the metal instrument
chassis, and to the power input filter in the instrument power supply. Terminals identified as
chassis in Figure 3-1a and Figure 3-1b are also internally connected to the protective ground.
The chassis terminals can be used for shield connections.

3.4.2 Circuit Common Connections

The instrument circuit common is isolated from the protective ground. This makes it easier to
avoid dc ground loops, and helps isolate the instrument from noise which may be present on
the protective ground.

Instrument common is the negative return for both built-in analog output circuits. Common is
available on terminals 18 and 39 for Model C, and 16 and 41 for Models A & B (see Figures
3-1a and 3-1b and Section 3-6).

Circuit common is also available at terminal 25 for connection to an instrument system
ground. If the installation does not include an instrument system ground, then connect circuit
common to one of the terminals identified as chassis in Figures 3-1a and 3-1b. Never leave
circuit common completely floating. Circuit common must always have some dc path to
ground to prevent the possible build up of static charges, and to reduce noise pickup.

3.4.3 Electrical Noise

Electrical disturbances can be caused by lightning, motors and motor driven devices, relays,
solenoids, and communication equipment. These disturbances often introduce electrical
noise in power lines, transmission lines, and site grounds. The successful operation of any
microprocessor-based device depends, in part, on the precautions taken to minimize the
effect of these disturbances. Often called "transients" or "voltage spikes", this form of noise
is infinitely variable in terms of amplitude, frequency, and duration.

Common sources of this type of noise are:

 loose or poor quality connections (especially power connections)

 arc welding equipment

 switches operating inductive loads

 relays, solenoids and other coil operated devices

 high current conductors – electric heater circuits

 fluorescent or neon lamps

 motors and motor driven devices

 switch mode devices – SCRs, thyristors

 lightning or electrostatic discharges

38

3.4.4 Noise Prevention Measures

Primary power circuit distribution system:

 Ideally, each microprocessor-based device should be provided with an independent

dedicated power source. Where this approach is not feasible due to space availability or

cost per device, an acceptable alternative is to install constant voltage, isolation

transformers in the branch circuit where the microprocessor-based device is installed.

In addition to the above, install a combination transient surge suppressor and noise filter



in the instrument side of the power distribution system. The combination device

suppresses transients and effectively reduces other noise forms such as electromagnetic

(EMI) and radio frequency (RFI) interferences. These devices can be connected to

multiple units to reduce overall cost.

Input signals

Twisted wire pairs are essential. The wire type should be stranded, not solid. The



largest wire gauge allowed is best and the more twists per foot the better. A 2-inch lay (6

twists per foot) should be the minimum used.

MOD 30ML Multiloop Controller

POWER, GROUNDING, AND BUILT-IN I/O CONNECTIONS

In addition to the above, signal wires should be physically isolated from all power



conductors (separate conduit, cable race, etc.)

 Shielded wire is also essential. Shields must be terminated at the instrument or in the

field in accordance with local regulations.

! CAUTION 1. Never terminate a shield at both ends. One end must always be left

"floating" or ground currents may be introduced.

2. Thermocouple shields should be terminated at the process

measurement end. Most thermocouples are constructed where the
sensor is electrically equivalent to the process connection (grounded
junction).

Equipment grounding:

Grounding practices defined by the National Fire Protection Agency (NFPA) in their



National Electrical Code (NEC) handbook or State agency amendments to this code

should be strictly observed.



Existing ground conductors and ground paths should be periodically inspected and

tested to insure continuity and compliance with current code requirements.

 For best noise reduction performance, the microprocessor-based device's ground

terminal should be connected to a nearby grounded large metal structure, using the

shortest length wire possible. If a three-wire cordset is used to power the

microprocessor-based device through a receptacle, the ground wire is generally too long

and too noisy to be a good ground.

POWER, GROUNDING, AND BUILT-IN I/O CONNECTIONS

3.5 BUILT-IN PROCESS INPUT CONNECTIONS

Built-in inputs 1 and 2 are isolated universal analog inputs which accept volts dc, millivolts dc,
milliamps dc (includes 2-wire transmitters), RTD, Thermocouple, and resistance signals.
Connections to these inputs are made to the terminals shown in Figure 3-2a (Model C) and
3-2b (Models A & B). The input circuit diagrams in this section (Figures 3-3 to 3-9) identify
Input 1 terminals as I/O 1 and Input 2 terminals as I/O 2.

Each of the two built-in analog input circuits is isolated from every other circuit. It is
recommended that either Input– or mA Input + be connected to ground at some point in the
system to prevent possible build-up of static electricity and reduce the pickup of noise.

Read this section thoroughly before making any connections to modules. Installation
personnel should be qualified technicians. Observe all electrical code requirements and
safety standards applicable to these wiring procedures.

Specific instructions and connection diagrams for the various input and output modules are
provided in Sections 4.3 and 4.4. A listing of the applicable electrical specifications is
included with each diagram.

4.2 MODULAR I/O CONNECTION GUIDELINES

The wiring connections described in this section are made with the controller installed in its
operating location and with the power off. Figure 4-1a shows the modular I/O connection
terminals for Model C and Figure 4-1b shows the modular I/O connection terminals for
Models A & B with the cover removed.

MOD 30ML Multiloop Controller

MODULAR I/O CONNECTIONS

The recommended procedure for making, connections to I/O modules is as follows:

1. The diagrams for single width modules show connections to a sample location (usually

location 1). The terminal numbers for the actual location being used must be determined

by matching pin numbers 1 and 2 in each diagram to the terminal numbers for the

selected location as shown in Figures 4-1a and 4-1b.

2. The spacing of module locations on the carrier board divides locations 1 through 10 into

pairs allowing double wide modules to occupy only five different locations. The terminal

numbers applicable to each dual location are shown on the connection diagrams for

double wide modules.

3. Route low-level signal wiring from the top left hand side of the housing and ac voltage

wiring from the bottom right hand side and distribute to appropriate terminals.

4. Use a small, flat-head screwdriver to loosen appropriate connection screws and clamps

on terminal blocks.

5. Strip approximately 5/16 inch (8 mm) of insulation from the end of each wire, insert wires

at assigned terminals, and secure terminal screws and clamps.

 WARNING All wiring connected to the controller terminals must be rated for the

maximum voltage present, or alternately, wiring in circuits operating at
greater than 30 volts must be rated for at least twice the circuit voltage.

6. After all connections are completed and checked, do the following:

a. If communications are required, follow the applicable procedure in Section 5.

b. If all connections are completed, the ac power wiring can be connected at the

distribution panel (ac source).

* NOTE: Before putting the controller into operation, it must be configured using

either the front panel keys or the PC configuration software. See
Section 1.1.2 for related documents.

4.3.1 2013A Thermocouple Input (TIM) and Cold Junction Compensation

Make thermocouple sensor connections as shown in Figure 4-2. The controller has
automatic cold junction compensation which must be enabled by connection of a
thermocouple to built-in input 1. When enabled, the automatic cold junction compensation
provides compensation for both built-in and modular inputs, and use of a cold junction
compensation module is not required. For any application requiring one or more
thermocouple inputs, it is recommended that the first thermocouple be connected to built-in
input 1 so that a cold junction module is not required.

In the event that a thermocouple cannot be connected to input 1, installation of a 2-wire RTD
module with a CJC sensor is required for cold junction compensation. This module senses
the temperature at the terminal block and provides cold junction compensation for all
thermocouples connected to the controller.

The RTD sensor used for cold junction compensation is a platinum 1000 ohm RTD with an
alpha of 0.00385. The sensor is Class B (0.12%) and has an operating temperature range of
–50°C to +650°C (–58°F to +1202°F). It is connected to a 2-wire RTD input module and
installed in the housing.

5.1 GENERAL

Read this section thoroughly before making connections. Installation personnel should be
qualified technicians.

The controller provides communications capability for both ICN and Modbus networks. Two
serial communication ports are available permitting the controller to communicate on two
different networks simultaneously. Port 1 can use either built-in or modular communication
drivers. Port 2 requires a modular driver. Communications connections are made to the
terminals shown in Figures 5-1a (Model C) and 5-b (Models A & B). The communications
network diagrams in this section show connections for both the built-in and modular
communications circuits.

In addition to the network communications capability, the controller provides an RS-232
communications port in the bottom of the front panel. This port permits connection of a
portable computer for data base configuration using the PC configuration software.

76

5.2 COMMUNICATION CONNECTION GUIDELINES

The wiring connections described in this section are made with the controller installed in its
operating location and with the power off. All connection terminals are located under a cover
on the back of the Model A & B instrument housing. Model C instruments do not have a
cover over the terminals. Figure 5-1b shows the Model A & B communication connection
terminals with the cover removed.

The recommended procedure for making communications connections is as follows:

1. Communications port 1 serves either the built-in communications circuits or I/O module
location S10 (S10 and S9 if module is double wide). It is recommended that the built-in
communication circuit be used for port 1. This leaves the module locations available for
other purposes.

2. Communications port 2 serves I/O module location S8 (S8 and S7 if module is double
wide). If required, a second communication network can be supported via this modular
connection.

3. When using communication port 1, a communications jumper on the carrier board, Figure
5-2, must be positioned to select the communication type for the built-in circuits, or to
deselect the built-in circuit if a module is used.

MOD 30ML Multiloop Controller

COMMUNICATIONS CONNECTIONS

4. The built-in communications circuits are isolated from all other circuits. Terminal 1 (TX &
RX common) is the communications circuit common for these built in circuits. When built­in communication is used, connect terminal 1 of each instrument on the communication
bus together. This common line must be connected to ground at some point in the
system to prevent the possible build up of a static charge, reduce noise pick up, and
comply with EU EMC requirements.

5. Communications wiring should be shielded twisted pairs. Detailed cable requirements
are provided in Sections 5.4 and 5.5.

6. The cable shields must be connected to a good noise free ground. Normally this should
be one of the terminals identified as chassis in Figure 3-1. Alternatively, it is acceptable
to use the shield to connect the commons among the instruments. If this arrangement is
used, noise rejection may not be optimal.

7. Route communications wiring from the top left hand side of the housing and distribute to
appropriate terminals.

8. Use a small, flat-head screwdriver to loosen appropriate connection screws and clamps
on terminal blocks.

9. Strip approximately 5/16 inch (8 mm) of insulation from the end of each wire, insert wires
at assigned terminals, and secure terminal screws and clamps.

10. Make wiring connections using the following procedures:
a. Front Panel RS-232 Communications Connections - Section 5.3.
b. Instrument Communications Network (ICN) Connections - Section 5.4.
c. Modbus Network Connections - Section 5.5.

11. After all connections are completed and checked, the ac power wiring can be connected
at the distribution panel (ac source).

* NOTE: Before putting the controller into operation, it must be configured using

either the front panel keys or the PC Configuration Software. See
Section 1.1.2 for related documents.

5.3 FRONT PANEL RS-232 COMMUNICATIONS CONNECTION

The RS-232 communication port in the instrument front panel, Figure 1-1 (NOT present with
NEMA 4), is used exclusively for data base configuration via connection of a portable
computer. Use of this RS-232 port is subject to the following requirements:

78

 Connection to the port must be made using a cable which is available as an accessory to

the instrument. The cable is terminated at one end with a plug-in connector for the
instrument port, and at the other end with a connector compatible with a computer serial
communication port.

 The communication jumper, Figure 5-2, must be positioned for RS-232 communication.

MOD 30ML Multiloop Controller

COMMUNICATIONS CONNECTIONS

 If connections are made to the built-in communication terminals, Figure 5-1, the

connections must support RS-232 communication
RS-232 port in the front panel is not functional.

 The instrument data base must be configured to provide RS-232 communication on the

built-in circuit; this is the default configuration.

When the built-in RS-232 circuit is being used for network communication, making a
connection to the front panel RS-232 port disables the network receive function so that the
instrument can receive data only from the device connected to the port. The transmit line is
not affected.

as shown in Figure 5-4, otherwise the

5.4 INSTRUMENT COMMUNICATIONS NETWORK (ICN) CONNECTIONS

An example of a typical ICN configuration with both modular and built-in connections is
shown in Figure 5-3.

Cable Requirements

5.4.1

The length of the ICN is the sum of the lengths of the physical two-wire bus between each
node on the ICN. If the network includes MOD 30 instruments, the length of any MOD 30
instrument cables between the nodes and the instruments must be included in the total
length. This length can be up to 2000 ft (609.6 m). Cable requirements for an ICN are
dependent upon the length of the ICN as described below.

 When the total length is 500 ft (150 m) or less, use 18 AWG (1 mm) shielded twisted pair

cable.

 When the total length is between 500 and 1500 ft (150 and 450 m):

- Entire length of the ICN must be at virtually the same potential and voltage drop

- Cable capacitance for an ICN must be between 18 and 25 pf/ft (60-83 pf/m).

 When the total length exceeds 1500 ft (450 m) or if the ICN must be routed through high

noise (EMI/RFI) environments, use 22 AWG (0.64 mm) shielded cable. If an ICN must
be run next to power lines or other unusual noise frequencies, contact your service
representative for assistance.

5.4.2 Addresses

Each device on an ICN must be assigned a unique address. Addresses are in the range of 0
through F hex (0 through 15 decimal). The address for the built-in circuit is configured
through the front face of the instrument in Device Setup (see IB-1800R-OPR Setup Section).
Addresses for modular circuits are set at the module as shown in Figure 5-3.

between any two points on ICN must not exceed 3V.

79

MOD 30ML Multiloop Controller

COMMUNICATIONS CONNECTIONS

80

Figure 5-3. ICN Connections for Built-in and Modular Communication Circuits

5.4.3 Termination

One set of ICN termination resistors must be installed on each ICN to prevent noise from
being picked up by the ICN circuitry and generating a diagnostic alarm. The ICN termination
scheme requires a nominal 24 volt DC power supply that can supply 15.4 mA. This supply is
provided by both the built-in and modular circuits. The termination resistor network is
provided in a 2030FZ00001A ICN Terminator. The terminator can be conveniently
connected to an ICN at built-in terminals 2 - 5 as shown in Figure 5-3. Note that the
terminator is connected to common via terminal 4 which is internally connected to terminal 1
(communications common) for ICN communication. The terminator can also be connected at
the appropriate four terminals when a communications module is used.

Other factors affecting the termination scheme are as follows.

 The ICN cable shields should be connected directly to chassis ground at one end only.

 Be sure each network has only one terminator. If the controller is connected to an

existing MOD 30 ICN, the network is already terminated and a terminator must not be
connected to any new device.

5.5 MODBUS NETWORK CONNECTIONS

5.5.1 General

Numerous Modbus network connection arrangements are possible. Selection of a specific
arrangement depends on the requirements of the application. The connection diagrams
shown in this section provide typical examples of connection schemes which meet all the
functional requirements of the Modbus protocol and the built-in and modular communication
circuits.

Master and Slave Designations

The controller can function as either a Modbus master or Modbus slave. This functionality is
determined by the configuration of the MSC block.

Communications Parameters

The baud rates available are: 150, 300, 600, 1200, 2400, 4800, 9600, 19200 or 38400.
Parity can be none, even or odd, and there can be either 1 or 2 stop bits. These parameters
are configurable via the MSC block.

The transmission mode of Modbus networks using either the built-in or modular circuits is
RTU (Remote Terminal Unit).

RS-485 Network Considerations

The RS-485 specification allows as many as 32 devices on any given network. The number
of devices can be increased by the use of repeaters. The Modbus network supports as many
as 247 slave devices.

MOD 30ML Multiloop Controller

COMMUNICATIONS CONNECTIONS

81

MOD 30ML Multiloop Controller

COMMUNICATIONS CONNECTIONS

RS-485 Cable Requirements

For short runs of 10 to 25 ft (3 to 6m), virtually any 2-wire shielded or twisted pair is suitable.
For runs up to 1000 ft (305 m), Belden 9502 Cable or an equivalent cable is recommended.
This cable is a dual 24 AWG (0.5 mm) twisted pair with an overall foil shield. A drain wire is
provided for grounding the shield. For runs up to 4000 ft (1219.2 m), Belden 9729 Cable or
an equivalent cable is recommended. This cable is a dual 24 AWG (0.5 mm) twisted pair
with a foil shield for each pair. The cable insulation is low dissipation (polypropylene). Two
separate drain wires are provided for grounding the shields

* NOTE: Heavy braid shield cable may be required for certain noisy environments.

Addresses

Each slave on a Modbus network must have a unique address. Addresses 1 through 247 (01
through f7 in hexadecimal) are supported by the Modbus protocol. Addresses for the built-in
circuit are assigned by configuration of a data base attribute. Addresses for modular circuits
are set at the module as shown in Figure 5-7.

Communication Defaults

The 2033N and 2034N RS-485 modules have a COMM DEFAULTS switch which provides
for communication with the module when its configuration is unknown. When the switch is
set at YES, a set of default parameters is invoked. The parameters are: 9600 Baud, no
parity, one stop bit, eight data bits, and the port functionality is slave.

5.5.2 RS-232 Modbus Communication

The built-in and modular circuits for RS-232 communication use a driver/receiver which
supports a point-to-point Modbus network. The modular circuit is contained in a 2033N
communications module. These circuits meet all RS-232C and V.28 specifications. They
have a±9V output swing with a+5V supply, and±30V receiver input levels. All field
connection terminals are optically isolated from the instrument circuitry. The maximum
network cable length is 50 feet.

Both the built-in and modular circuits support the Extended Modbus protocol which provides
full communications functionality between controllers, and between the controllers and any
PC software.

! CAUTION: If the modular communication option is used, be sure the module is

wired properly before applying power. Although this module is isolated,
it can be damaged if excessive voltage is applied across the input pins.
This module is not a drop-in replacement for the ICN module (2030N),
and will be damaged if ICN level voltages are applied to the input pins.

Connections for a typical RS-232 Modbus network using the built-in circuit is shown in Figure
5-4, and connections using the modular circuit are shown in Figure 5-5. Either a computer or
the controller can act as the Modbus master.

5.5.3 RS-485 2-Wire Modbus Communication

The built-in and modular circuits for RS-485 2-wire communication use a transceiver which
supports a 2-wire point-to-point or point-to-multipoint Modbus network. The modular circuit is
contained in a 2032N communications module. All field connection terminals are isolated
from the instrument circuitry.

! CAUTION: If the modular communication option is used, be sure the module is

wired properly before applying power. Although this module is isolated,
it can be damaged if excessive voltage is applied across the input pins.
This module is not a drop-in replacement for the ICN module (2030N),
and will be damaged if ICN level voltages are applied to the input pins.

Connections for a typical RS-485 2-wire Modbus network are shown in Figure 5-6. In this
network, the personal computer acts as the Modbus master and the controller is the slave.
The master is responsible for providing the bus stabilizing pull-up and pull-down resistors
which keep the bus in a MARK/IDLE state when all the transmitters are tri-stated. Connect
120 ohm termination resistors across the transmission line at both ends as shown. The
termination resistors may not be required if the line length is very short.

The built-in communications circuit provides a communications common connection at
terminal 1 to provide improved noise resistance. The modular circuit does not use a
communications common. When using the built-in circuit, connect the communications
common as follows:

MOD 30ML Multiloop Controller

COMMUNICATIONS CONNECTIONS

 Connect to terminal 1 of all instruments communicating on the network via the built-in

circuit.

 Connect to the RS-485 interface board in the personal computer if a communications

common terminal is available.

 Connect to ground at some point in the system.

5.5.4 RS-485 4-Wire Modbus Communication

The built-in and modular circuits for RS-485 4-wire communication use a pair of transceivers
which support a 4-wire point-to-point or point-to-multipoint Modbus network. The modular
circuit is contained in a 2034N communications module. All field connection terminals are
isolated from the instrument circuitry.

Both the built-in and modular circuits support the Extended Modbus protocol which provides
full communications functionality between controllers, and between a controller and any PC
software.

! CAUTION: If the modular communication option is used, be sure the module is

wired properly before applying power. Although this module is isolated,
it can be damaged if excessive voltage is applied across the input pins.
This module is not a drop-in replacement for the ICN module (2030N),
and will be damaged if ICN level voltages are applied to the input pins.

P C Master

The diagram in Figure 5-8 shows connections for a typical RS-485 4-wire Modbus network in
which a personal computer acts as the Modbus master and the controller is the slave. The
master is responsible for providing the bus stabilizing resistors. When using the modular
communications circuit, the module provides the slave function, and the TERM switch on the
module must be set at NO to disconnect the resistors inside the module. Connect 120 ohm
termination resistors across the transmission line at both ends as shown. The termination
resistors may not be required if the line length is very short.

Controller Master

The diagram in Figure 5-9 shows connections for a typical RS-485 4-wire Modbus network in
which one controller acts as the master, and the other controllers on the network are slaves.
In this network, it is recommended that the modular communications circuit be used in the
master because the 2034N module provides the required bus stabilizing resistors. The
TERM switch on the master module must be set at YES to connect the resistors to the
network. The TERM switch on each slave module must be set at NO to disconnect the
resistors inside the module. Connect 120 ohm termination resistors across the transmission
line at both ends as shown. These resistors may not be required if the line length is very
short.

Communications Common

The built-in communications circuit has a communications common connection at terminal 1
to provide improved noise resistance. The modular circuits do not use a communications
common. When using the built-in circuit, connect a communications common line as follows:

4-Wire/2-Wire Network

When several slaves on a network require only read and write capability, a mixture of 2-wire
and 4-wire communication can be used to save slot space and transmission cable as shown
in Figure 5-10. This arrangement allows a series of 2-wire slave controllers to be connected
to a 4-wire master controller. The master provides the required bus stabilizing resistors via a
2034N module. The slaves are adequate for the read/write function using either the built-in
circuit or a 2-wire 2032N single wide module.
