ATTENTION

UNSUPPORTED CONNECTION

Do not connect a MicroLogix 1100 controller to another MicroLogix family controller such as MicroLogix 1000, MicroLogix 1200, MicroLogix 1500, or the network port of a 1747-DPS1 Port Splitter using a 1761- CBL-AM00 (8-pin mini-DIN to 8-pin mini-DIN) cable or equivalent.

This type of connection will cause damage to the RS-232/485 communication port (Channel 0) of the MicroLogix 1100 and/or the controller itself. The communication pins used for RS-485 communications on the MicroLogix 1100 are alternately used for 24V power on the other MicroLogix controllers and the network port of the 1747-DPS1 Port Splitter.

Publication 1763-UM001D-EN-P - March 2011

16 Hardware Overview

Programming

Communication Options

Programming the MicroLogix 1100 controller is done using RSLogix 500, Revision 7.0 or later. To use all of the latest features, RSLogix 500 programming software must be version 7.20.00 or later. Communication cables for programming are available separately from the controller and software.

The MicroLogix 1100 controllers provide two communications ports, an isolated combination RS-232/485 communication port (Channel 0) and an Ethernet port (Channel 1).

The isolated Channel 0 port on the MicroLogix 1100 can be connected to the following:

• operator interfaces, personal computers, etc. using DF1 Full Duplex

point-to-point

• a DH-485 network

• a DF1 Radio Modem network

• a DF1 half-duplex network as an RTU Master or RTU Slave

• a Modbus network as an RTU Master or RTU Slave

• an ASCII network

• a DeviceNet network as a slave or peer using a DeviceNet Interface

(catalog number 1761-NET-DNI)

• an Ethernet network using the Ethernet Interface module (catalog

number 1761-NET-ENI, or 1761-NET-ENIW)

(1)

When connecting to a DH-485 network, DF1 half-duplex network

or a Modbus network, the MicroLogix 1100 can be connected directly via Channel 0 (without an Advanced Interface Converter, catalog number 1761-NET-AIC). The Channel 0 combo port provides both RS-232 and RS-485 isolated connections. The appropriate electrical interface is selected through your choice of communication cable. The existing MicroLogix 1761 communication cables provide an interface to the RS-232 drivers. The 1763-NC01 cable provides an interface to the RS-485 drivers (for DH-485,

Hardware Overview 17

The MicroLogix 1100 supports Ethernet communication via the Ethernet communication Channel 1. You can connect your controller to a local area network that provides communication between various devices at 10 Mbps or 100 Mbps. This port supports CIP explicit messaging (message exchange) only. The controller cannot be used for CIP implicit messaging (real-time I/O messaging). The controller also includes an embedded web server which allows viewing of not only module information, TCP/IP configuration, and diagnostic information, but also includes the data table memory map and data table monitor screen using a standard web browser.

Installing Your Controller 21

ATTENTION

WARNING

Electrostatic discharge can damage semiconductor devices inside the controller. Do not touch the connector pins or other sensitive areas.

Vertical mounting of the controller is not supported due to heat build-up considerations.

Be careful of metal chips when drilling mounting holes for your controller or other equipment within the enclosure or panel. Drilled fragments that fall into the controller or I/O modules could cause damage. Do not drill holes above a mounted controller if the protective debris shields are removed or the processor is installed.

Disconnecting Main Power

Explosion Hazard

Do not replace components, connect equipment, or disconnect equipment unless power has been switched off.

The main power disconnect switch should be located where operators and maintenance personnel have quick and easy access to it. In addition to disconnecting electrical power, all other sources of power (pneumatic and hydraulic) should be de-energized before working on a machine or process controlled by a controller.

Safety Circuits

Explosion Hazard

Do not connect or disconnect connectors while circuit is live.

Circuits installed on the machine for safety reasons, like overtravel limit switches, stop push buttons, and interlocks, should always be hard-wired directly to the master control relay. These devices must be wired in series so that when any one device opens, the master control relay is de-energized, thereby removing power to the machine. Never alter these circuits to defeat their function. Serious injury or machine damage could result.

Publication 1763-UM001D-EN-P - March 2011

Installing Your Controller 23

Power Distribution

There are some points about power distribution that you should know:

• The master control relay must be able to inhibit all machine motion by

removing power to the machine I/O devices when the relay is de-energized. It is recommended that the controller remain powered even when the master control relay is de-energized.

• If you are using a DC power supply, interrupt the load side rather than

the AC line power. This avoids the additional delay of power supply turn-off. The DC power supply should be powered directly from the fused secondary of the transformer. Power to the DC input and output circuits should be connected through a set of master control relay contacts.

Periodic Tests of Master Control Relay Circuit

Any part can fail, including the switches in a master control relay circuit. The failure of one of these switches would most likely cause an open circuit, which would be a safe power-off failure. However, if one of these switches shorts out, it no longer provides any safety protection. These switches should be tested periodically to assure they will stop machine motion when needed.

Publication 1763-UM001D-EN-P - March 2011

24 Installing Your Controller

Power Considerations

The following explains power considerations for the micro controllers.

Isolation Transformers

You may want to use an isolation transformer in the AC line to the controller. This type of transformer provides isolation from your power distribution system to reduce the electrical noise that enters the controller and is often used as a step-down transformer to reduce line voltage. Any transformer used with the controller must have a sufficient power rating for its load. The power rating is expressed in volt-amperes (VA).

Power Supply Inrush

During power-up, the MicroLogix 1100 power supply allows a brief inrush current to charge internal capacitors. Many power lines and control transformers can supply inrush current for a brief time. If the power source cannot supply this inrush current, the source voltage may sag momentarily.

The only effect of limited inrush current and voltage sag on the MicroLogix 1100 is that the power supply capacitors charge more slowly. However, the effect of a voltage sag on other equipment should be considered. For example, a deep voltage sag may reset a computer connected to the same power source. The following considerations determine whether the power source must be required to supply high inrush current:

• The power-up sequence of devices in a system.

• The amount of the power source voltage sag if the inrush current

cannot be supplied.

• The effect of voltage sag on other equipment in the system.

If the entire system is powered-up at the same time, a brief sag in the power source voltage typically will not affect any equipment.

Loss of Power Source

The power supply is designed to withstand brief power losses without affecting the operation of the system. The time the system is operational during power loss is called program scan hold-up time after loss of power. The duration of the power supply hold-up time depends on the type and state of the I/O, but is typically between 10 milliseconds and 3 seconds. When the duration of power loss reaches this limit, the power supply signals the processor that it can no longer provide adequate DC power to the system.

Publication 1763-UM001D-EN-P - March 2011

Installing Your Controller 25

TIP

This is referred to as a power supply shutdown. The processor then performs an orderly shutdown of the controller.

Input States on Power Down

The power supply hold-up time as described above is generally longer than the turn-on and turn-off times of the inputs. Because of this, the input state change from “On” to “Off ” that occurs when power is removed may be recorded by the processor before the power supply shuts down the system. Understanding this concept is important. The user program should be written to take this effect into account.

Other Types of Line Conditions

Occasionally the power source to the system can be temporarily interrupted. It is also possible that the voltage level may drop substantially below the normal line voltage range for a period of time. Both of these conditions are considered to be a loss of power for the system.

Preventing Excessive Heat

For most applications, normal convective cooling keeps the controller within the specified operating range. Ensure that the specified temperature range is maintained. Proper spacing of components within an enclosure is usually sufficient for heat dissipation.

In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure. In this case, place blower fans inside the enclosure to assist in air circulation and to reduce “hot spots” near the controller.

Additional cooling provisions might be necessary when high ambient temperatures are encountered.

Do not bring in unfiltered outside air. Place the controller in an enclosure to protect it from a corrosive atmosphere. Harmful contaminants or dirt could cause improper operation or damage to components. In extreme cases, you may need to use air conditioning to protect against heat build-up within the enclosure.

Publication 1763-UM001D-EN-P - March 2011

26 Installing Your Controller

ATTENTION

TIP

Master Control Relay

A hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint. Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens, the master control relay is de-energized. This removes power to input and output device circuits. Refer to the figures on pages 28 and 29.

Never alter these circuits to defeat their function since serious injury and/or machine damage could result.

If you are using an external DC power supply, interrupt the DC output side rather than the AC line side of the supply to avoid the additional delay of power supply turn-off.

The AC line of the DC output power supply should be fused.

Connect a set of master control relays in series with the DC power supplying the input and output circuits.

Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it. If you mount a disconnect switch inside the controller enclosure, place the switch operating handle on the outside of the enclosure, so that you can disconnect power without opening the enclosure.

Whenever any of the emergency-stop switches are opened, power to input and output devices should be removed.

When you use the master control relay to remove power from the external I/O circuits, power continues to be provided to the controller’s power supply so that diagnostic indicators on the processor can still be observed.

The master control relay is not a substitute for a disconnect to the controller. It is intended for any situation where the operator must quickly de-energize I/O devices only. When inspecting or installing terminal connections, replacing output fuses, or working on equipment within the enclosure, use the disconnect to shut off power to the rest of the system.

Publication 1763-UM001D-EN-P - March 2011

Installing Your Controller 27

TIP

Do not control the master control relay with the controller. Provide the operator with the safety of a direct connection between an emergency-stop switch and the master control relay.

Using Emergency-Stop Switches

When using emergency-stop switches, adhere to the following points:

• Do not program emergency-stop switches in the controller program.

Any emergency-stop switch should turn off all machine power by turning off the master control relay.

• Observe all applicable local codes concerning the placement and

labeling of emergency-stop switches.

• Install emergency-stop switches and the master control relay in your

system. Make certain that relay contacts have a sufficient rating for your application. Emergency-stop switches must be easy to reach.

• In the following illustration, input and output circuits are shown with

MCR protection. However, in most applications, only output circuits require MCR protection.

The following illustrations show the Master Control Relay wired in a grounded system.

In most applications input circuits do not require MCR protection; however, if you need to remove power from all field devices, you must include MCR contacts in series with input power wiring.

IMPORTANT

Using the Battery

The MicroLogix 1100 controller is equipped with a replaceable battery. The Battery Low indicator on the LCD display of the controller shows the status of the replaceable battery. When the battery is low, the indicator is set (displayed as a solid rectangle). This means that either the battery wire connector is disconnected, or the battery may fail within 2 weeks if it is connected. When the battery level is acceptable, the indicator is clear (displayed as an empty rectangle).

The MicroLogix 1100 controller ships with the battery wire connector connected.

Ensure that the battery wire connector is inserted into the connector port if your application needs battery power. For example, when using a real-time clock (RTC), or to store the program in the controller's memory for an extended period of time while the power is removed.

See Lithium Battery (1763-BA) in the appendix B, for more information on installation, handling, usage, storage, and disposal of the battery.

SeeRTC Battery Operation on page 142, for more information on the use of the battery in relation with RTC.

When the controller’s Battery Low indicator is set (displayed as a solid rectangle) with the battery wire connector connected, we recommend strongly to install a new battery immediately.

ATTENTION

WARNING

Connecting Expansion I/O

The expansion I/O module is attached to the controller or another I/O module by means of a flat ribbon cable after mounting, as shown below.

Use the pull loop on the connector to disconnect modules. Do not pull on the ribbon cable.

Up to four expansion I/O modules can be connected to a controller.

Remove power before removing or inserting an I/O module. When you remove or insert a module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:

• sending an erroneous signal to your system’s field

devices, causing the controller to fault

• causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance, reducing product reliability.

EXPLOSION HAZARD

In Class I, Division 2 applications, the bus connector must be fully seated and the bus connector cover must be snapped in place.

In Class I, Division 2 applications, all modules must be mounted in direct contact with each other as shown on page 39. If DIN rail mounting is used, an end stop must be installed ahead of the controller and after the last 1762 I/O module.

Wiring Your Controller

This chapter describes how to wire your controller and expansion I/O. Topics include:

• wire requirements

• using surge suppressors

• grounding the controller

• wiring diagrams

• sinking and sourcing wiring diagrams

• controller I/O wiring

• wiring your analog channels

• expansion I/O wiring

Wiring Requirements

Wiring Recommendation

Before you install and wire any device, disconnect power to the controller system.

Calculate the maximum possible current in each power and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. Current above the maximum ratings may cause wiring to overheat, which can cause damage.

United States Only: If the controller is installed within a potentially hazardous environment, all wiring must comply with the requirements stated in the National Electrical Code 501-10 (b).

• Allow for at least 50 mm. (2 in.) between I/O wiring ducts or terminal

strips and the controller.

• Route incoming power to the controller by a path separate from the

device wiring. Where paths must cross, their intersection should be perpendicular.

41 Publication 1763-UM001D-EN-P - March 2011

42 Wiring Your Controller

TIP

Do not run signal or communications wiring and power wiring in the same conduit. Wires with different signal characteristics should be routed by separate paths.

• Separate wiring by signal type. Bundle wiring with similar electrical

characteristics together.

• Separate input wiring from output wiring.

• Label wiring to all devices in the system. Use tape, shrink-tubing, or

other dependable means for labeling purposes. In addition to labeling, use colored insulation to identify wiring based on signal characteristics. For example, you may use blue for DC wiring and red for AC wiring.

Wiring the Terminal Block

The MicroLogix 1100 controllers have screw-cage clamps on the input and output terminal blocks. With screw-cage clamp terminal blocks, there is no need to attach additional hardware such as a spade lug to the wire, or use a finger-safe cover.

To wire the terminal block:

1. Strip the end of the wire.

The recommended length for the stripped end of the wire is 11.0 mm (0.440 in.).

2. Insert it into an open clamp.

3. Using a small, flat-blade screwdriver, tighten the terminal screw. To

ensure that the wire conductor is secured inside the clamp, tighten it to the rated torque, 0.56 Nm (5.0 in-lb).

The diameter of the terminal screw head is 5.5 mm (0.220 in.).

Using Surge Suppressors

Because of the potentially high current surges that occur when switching inductive load devices, such as motor starters and solenoids, the use of some type of surge suppression to protect and extend the operating life of the controllers output contacts is required. Switching inductive loads without surge suppression can significantly reduce the life expectancy of relay contacts. By adding a suppression device directly across the coil of an inductive device, you prolong the life of the output or relay contacts. You also reduce the effects of voltage transients and electrical noise from radiating into adjacent systems.

The following diagram shows an output with a suppression device. We recommend that you locate the suppression device as close as possible to the load device.

If the outputs are DC, we recommend that you use an 1N4004 diode for surge suppression, as shown below. For inductive DC load devices, a diode is suitable. A 1N4004 diode is acceptable for most applications. A surge

Grounding stamping

Grounding the Controller

All devices connected to the RS-232/485 communication port must be referenced to controller ground, or be floating (not referenced to a potential other than ground). Failure to follow this procedure may result in property damage or personal injury.

• For 1763-L16BWA controllers, the COM of the sensor supply is also connected to

chassis ground internally. The 24V DC sensor power source should not be used to power output circuits. It should only be used to power input devices.

• For 1763-L16BBB and 1763-L16DWD controllers, the VDC NEUT or common terminal

of the power supply is also connected to chassis ground internally.

In solid-state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw of the controller to the ground bus prior to connecting any devices. Use AWG #14 wire. For AC-powered controllers, this connection must be made for safety purposes.

This product is intended to be mounted to a well grounded mounting surface such as a metal panel. Refer to the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional information. Additional grounding connections from the mounting tab or DIN rail, if used, are not required unless the mounting surface cannot be grounded.

Use all four mounting positions for panel mounting installation.

Remove the protective debris strip before applying power to the controller. Failure to remove the strip may cause the controller to overheat.

Minimizing Electrical Noise

Because of the variety of applications and environments where controllers are installed and operating, it is impossible to ensure that all environmental noise will be removed by input filters. To help reduce the effects of environmental noise, install the MicroLogix 1100 system in a properly rated (for example, NEMA) enclosure. Make sure that the MicroLogix 1100 system is properly grounded.

A system may malfunction due to a change in the operating environment after a period of time. We recommend periodically checking system operation, particularly when new machinery or other noise sources are installed near the MicroLogix 1100 system.

Analog input circuits can monitor voltage signals and convert them to serial digital data.

Analog Channel Wiring Guidelines

Consider the following when wiring your analog channels:

• The analog common (COM) is connected to earth ground inside the

module. These terminals are not electrically isolated from the system. They are connected to chassis ground.

• Analog channels are not isolated from each other.

• Use Belden™ 8761, or equivalent, shielded wire.

• Under normal conditions, the drain wire (shield) should be connected to

the metal mounting panel (earth ground). Keep the shield connection to earth ground as short as possible.

• To ensure optimum accuracy for voltage type inputs, limit overall cable

impedance by keeping all analog cables as short as possible. Locate the I/O system as close to your voltage type sensors or actuators as possible.

Minimizing Electrical Noise on Analog Channels

Inputs on analog channels employ digital high-frequency filters that significantly reduce the effects of electrical noise on input signals. However, because of the variety of applications and environments where analog controllers are installed and operated, it is impossible to ensure that all environmental noise will be removed by the input filters.

Several specific steps can be taken to help reduce the effects of environmental noise on analog signals:

• install the MicroLogix 1100 system in a properly rated (i.e., NEMA)

enclosure. Make sure that the MicroLogix 1100 system is properly grounded.

• use Belden cable #8761 for wiring the analog channels, making sure that

the drain wire and foil shield are properly earth grounded.

• route the Belden cable separately from any AC wiring. Additional noise

immunity can be obtained by routing the cables in grounded conduit.

Grounding Your Analog Cable

Use shielded communication cable (Belden #8761). The Belden cable has two signal wires (black and clear), one drain wire, and a foil shield. The drain wire and foil shield must be grounded at one end of the cable.

Do not ground the drain wire and foil shield at both ends of the cable

Chapter

Communication Connections

This chapter describes how to communicate with your control system. The method you use and cabling required to connect your controller depends on what type of system you are employing. This chapter also describes how the controller establishes communication with the appropriate network. Topics include:

• supported communication protocols

• default communication configurations

• using communications toggle functionality

• connecting to RS-232 port

• connecting to DH-485 network

• connecting to AIC+

• connecting to DeviceNet

• connecting to Ethernet

Supported Communication Protocols

The MicroLogix 1100 controllers provide two communication channels, an isolated RS-232/485 communication port (Channel 0) and an Ethernet port (Channel 1).

MicroLogix 1100 controllers support the following communication protocols from the primary RS-232/485 communication channel, Channel 0:

• DH-485

• DF1 Full-Duplex

• DF1 Half-Duplex Master and Slave

• DF1 Radio Modem

• Modbus Master and Slave

• ASCII

The Ethernet communication channel, Channel 1, allows your controller to be connected to a local area network for various devices providing 10 Mbps/100 Mbps transfer rate. MicroLogix 1100 controllers support CIP explicit messaging (message exchange). MicroLogix 1100 controllers do not support Ethernet I/O master capability through CIP implicit messaging (real-time I/O messaging).

Connecting to the RS-232 Port

There are two ways to connect the MicroLogix™ 1100 programmable controller to your personal computer using the DF1 protocol: using a point-to-point connection, or using a modem. Descriptions of these methods follow.

• For 1763-L16BWA controllers, the COM of the

sensor supply is also connected to chassis ground internally. The 24V DC sensor power source should not be used to power output circuits. It should only be used to power input devices.

• For 1763-L16BBB and 1763-L16DWD controllers,

the VDC NEUT or common terminal of the power supply is also connected to chassis ground internally.

Do not connect a MicroLogix 1100 controller to another MicroLogix family controller such as MicroLogix 1000, MicroLogix 1200, MicroLogix 1500, or to the 1747-DPS1 Network port using a 1761-CBL-AM00 (8-pin mini-DIN to 8-pin mini-DIN) cable or equivalent.

This type of connection will cause damage to the RS-232/485 communication port (Channel 0) of the MicroLogix 1100 and/or the controller itself. Communication pins used for RS-485 communications are alternately used for 24V power on the other MicroLogix controllers and the 1747-DPS1network port .

Making a DF1 Point-to-Point Connection

You can connect the MicroLogix™ 1100 programmable controller to your personal computer using a serial cable (1761-CBL-PM02) from your personal computer’s serial port to the controller’s Channel 0. The recommended protocol for this configuration is DF1 Full-Duplex.

You can connect a MicroLogix 1100 controller to your personal computer directly without using an external optical isolator, such as Advanced Interface Converter (AIC+), catalog number 1761-NET-AIC, as shown in the illustration below, because Channel 0 is isolated within the controller.

Poll Timeout only applies when a slave device initiates a MSG instruction. It is the amount of time that the slave device waits for a poll from the master device. If the slave device does not receive a poll within the Poll Timeout, a MSG instruction error is generated, and the ladder program needs to requeue the MSG instruction. If you are using a MSG instruction, it is recommended that a Poll Timeout value of zero not be used. Poll Timeout is disabled when set to zero.

TIP

Connecting to a DH-485 Network

The network diagrams on the next pages provide examples of how to connect MicroLogix 1100 controllers to the DH-485 network.

You can connect a MicroLogix 1100 controller to your DH-485 network directly without using an external optical isolator, such as Advanced Interface Converter (AIC+), catalog number 1761-NET-AIC, as shown in the illustrations below, because Channel 0 is isolated within the controller.

Use a 1763-NC01 Series A or later (8-pin mini-DIN to 6-pin DH-485 connector) cable or equivalent to connect a MicroLogix 1100 controller to a DH-485 network.

Recommended Tools

To connect a DH-485 network to additional devices, you need tools to strip the shielded cable and to attach the cable to the AIC+ Advanced Interface Converter. We recommend the following equipment (or equivalent):

Working with Cable for DH-485 Network

Description Part Number Manufacturer

Shielded Twisted Pair Cable #3106A or #9842 Belden Stripping Tool Not Applicable Not Applicable 1/8” Slotted Screwdriver Not Applicable Not Applicable

DH-485 Communication Cable

The suggested DH-485 communication cable is either Belden #3106A or #9842. The cable is jacketed and shielded with one or two twisted-wire pairs and a drain wire.

One pair provides a balanced signal line and one additional wire is used for a common reference line between all nodes on the network. The shield reduces the effect of electrostatic noise from the industrial environment on network communication.

The communication cable consists of a number of cable segments daisy-chained together. The total length of the cable segments cannot exceed 1219 m (4000 ft). However, two segments can be used to extend the DH-485

network to 2438 m (8000 ft). For additional information on connections using the AIC+, refer to the Advanced Interface Converter (AIC+) User Manual, publication 1761-6.4.

When cutting cable segments, make them long enough to route them from one AIC+ to the next, with sufficient slack to prevent strain on the connector. Allow enough extra cable to prevent chafing and kinking in the cable.

Use these instructions for wiring the Belden #3106A or #9842 cable. (See

Cable Selection Guide on page 90 if you are using standard Allen-Bradley

cables.)

Connecting the Communication Cable to the DH-485 Connector

A daisy-chained network is recommended. Do not make the incorrect connection shown below:

Grounding and Terminating the DH-485 Network

Only one connector at the end of the link must have Terminals 1 and 2 jumpered together. This provides an earth ground connection for the shield of the communication cable.

Both ends of the network must have Terminals 5 and 6 jumpered together, as shown below. This connects the termination impedance (of 120 ohm) that is built into each AIC+ or the 1763-NC01 cable as required by the DH-485 specification.

Connecting the AIC+

You can connect a MicroLogix 1100 controller to a DH-485 network via Channel 0 directly without using an optical isolator, such as AIC+, catalog number 1761-NET-AIC, because Channel 0 is isolated. However, you need to use an AIC+ to connect your PC or other MicroLogix Family products, such as MicroLogix 1200, to a DH-485 network.

The following figure shows the external wiring connections and specifications of the AIC+.

WARNING

Safety Considerations

This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or non-hazardous locations only.

EXPLOSION HAZARD

AIC+ must be operated from an external power source.

This product must be installed in an enclosure. All cables connected to the product must remain in the enclosure or be protected by conduit or other means.

See Safety Considerations on page 21 for additional information.

Install and Attach the AIC+

1. Take care when installing the AIC+ in an enclosure so that the cable connecting the MicroLogix™ controller to the AIC+ does not interfere with the enclosure door.

2. Carefully plug the terminal block into the RS-485 port on the AIC+ you are putting on the network. Allow enough cable slack to prevent stress on the plug.

3. Provide strain relief for the Belden cable after it is wired to the terminal block. This guards against breakage of the Belden cable wires.

Powering the AIC+

MicroLogix 100, 1200, and 1500 programmable controllers support 24V DC communication power on Channel 0. When connected to the 8 pin mini-DIN connector on the 1761-NET-AIC, 1761-NET-ENI, and the 1761-NET-ENIW, these controllers provide the power for the interface converter modules. The MicroLogix 1100 does not provide 24V DC communication power. Instead these pins are used to provide RS-485 communications directly. Any AIC+, ENI, or ENIW not connected to a MicroLogix 1000, 1200, or 1500 controller requires a 24V DC power supply.

If both the controller and external power are connected to the AIC+, the power selection switch determines what device powers the AIC+.

If you use an external power supply, it must be 24V DC (-15%/+20%). Permanent damage results if a higher voltage supply is used.

Set the DC Power Source selector switch to EXTERNAL before connecting the power supply to the AIC+. The following illustration shows where to connect external power for the AIC+.

Always connect the CHS GND (chassis ground) terminal to the nearest earth ground. This connection must be made whether or not an external 24V DC supply is used.

Publication 1763-UM001D-EN-P - March 2011

96 Communication Connections

ATTENTION

Power Options

Below are two options for powering the AIC+:

• Use the 24V DC user power supply built into the MicroLogix™ 1000,

1200, or 1500 controller. The AIC+ is powered through a hard-wired connection using a communication cable (1761-CBL-HM02, or equivalent) connected to port 2.

• Use an external DC power supply with the following specifications:

– operating voltage: 24V DC (-15%/+20%) – output current: 150 mA minimum – rated NEC Class 2

Make a hard-wired connection from the external supply to the screw terminals on the bottom of the AIC+.

If you use an external power supply, it must be 24V DC (-15%/+20%). Permanent damage results if miswired with the wrong power source.
