Master

Control Relay

A hard-wired master control relay (MCR) provides a reliable means for emergency controller 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 figure on page 1–5.

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

Important: If you are using an external dc output 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 external 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.

Important: 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.

Important: The illustrations only show output circuits with MCR

protection. 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.

Using Surge Suppressors

Inductive load devices such as motor starters and solenoids require the use of some type of surge suppression to protect the controller output contacts. Switching inductive loads without surge suppression can significantly

reduce the lifetime of relay contacts. By adding a suppression device directly across the coil of an inductive device, you will prolong the life of the switch contacts. You also reduce the effects of voltage transients caused by interrupting the current to that inductive device, and prevent electrical noise from radiating into system wiring.

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.

Suitable surge suppression methods for inductive ac load devices include a varistor, an RC network, or an Allen-Bradley surge suppressor, all shown below. These components must be appropriately rated to suppress the switching transient characteristic of the particular inductive device. See the table on page 1–9 for recommended suppressors.

RC Network

If you connect a micro controller triac output to control an inductive load, we recommend that you use varistors to suppress noise. Choose a varistor that is appropriate for the application. The suppressors we recommend for triac outputs when switching 120V ac inductive loads are a Harris MOV, part number V175 LA10A, or an Allen-Bradley MOV, catalog number 599-K04 or 599-KA04. Consult the varistor manufacturer’s data sheet when selecting a varistor for your application.

For inductive dc load devices, a diode is suitable. A 1N4004 diode is acceptable for most applications. A surge suppressor can also be used. See the table on page 1–9 for recommended suppressors.

As shown in the illustration below, these surge suppression circuits connect directly across the load device. This reduces arcing of the output contacts. (High transient can cause arcing that occurs when switching off an inductive device.)

Safety Considerations

Safety considerations are an important element of proper system installation. Actively thinking about the safety of yourself and others, as well as the condition of your equipment, is of primary importance. We recommend reviewing the following safety considerations.

Disconnecting

Main Power

ATTENTION: Explosion Hazard — Do not replace components or disconnect equipment unless power has been switched off and

the area is known to be non-hazardous.

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.

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.

Power Distribution

Power Considerations

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.

• 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 is connected through a set of master control relay contacts.

Periodic T

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.

The following explains power considerations for the micro controllers.

ests of Master Control Relay Circuit

Isolation T

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 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

The MicroLogix power supply does not require or need a high inrush current. However, if the power source can supply a high inrush current, the MicroLogix power supply will accept it. There is a high level of inrush current when a large capacitor on the input of the MicroLogix is charged up quickly.

If the power source cannot supply high inrush current, the only effect is that the MicroLogix input capacitor charges up more slowly. The following considerations determine whether the power source needs to supply a high inrush current:

our Controller

• power-up sequence of devices in system

• power source sag if it cannot source inrush current

• the effect of the voltage sag on other equipment

If the power source cannot provide high inrush current when the entire system in an application is powered, the MicroLogix powers-up more slowly. If part of an application’s system is already powered and operating when the MicroLogix is powered, the source voltage may sag while the MicroLogix input capacitor is charging. A power source voltage sag can affect other equipment connected to the same power source. For example, a voltage sag may reset a computer connected to the same power source.

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 20 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. This is referred to as a power supply shutdown.

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. 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

Controller Spacing

For most applications, normal convective cooling keeps the controller within the specified operating range. Ensure that the specified operating 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.

Important: 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.

The following figure shows the recommended minimum spacing for the controller. (Refer to appendix A for controller dimensions.)

• grounding guidelines

• sinking and sourcing circuits

• wiring recommendations

• wiring diagrams, input voltage ranges, and output voltage ranges

Grounding

Guidelines

In solid-state control systems, grounding helps limit the effects of noise due to electromagnetic interference (EMI). Use the heaviest wire gauge listed for wiring your controller with a maximum length of 152.4 mm (6 in.). Run the ground connection from the ground screw of the controller (third screw from left on output terminal rung) to the ground bus.

Important:

This symbol denotes a functional earth ground terminal which provides a low impedance path between electrical circuits and earth for non-safety purposes, such as noise immunity improvement.

Protective Wrap (remove after wiring)

ATTENTION: All devices that connect to the user 24V power supply or to the RS-232 channel must be referenced to chassis ground or floating. Failure to follow this procedure may result in property damage or personal injury.

ATTENTION: Chassis ground, user 24V ground, and RS-232 ground are internally connected. You must connect the chassis

ground terminal screw to chassis ground prior to connecting any devices.

ATTENTION: On the 1761-L10BWB, 1761-L16BWB,

1761-L16BBB, 1761-L20BWB-5A, 1761-L32BBB, and 1761-L32BWB

controllers, the user supply 24V dc IN and chassis ground are internally connected.

Chapter 2

Wiring Your Controller

ATTENTION: 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.

ATTENTION: 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 501-4 (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.

Important: 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.

Minimizing Electrical Noise on Analog Controllers

Grounding Y

our Analog Cable

Inputs on analog employ digital high frequency filters that significantly reduce the ef 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:

fects of electrical noise on input signals. However, because of

• install the MicroLogix 1000 system in a properly rated (i.e., NEMA)

enclosure. Make sure that the MicroLogix 1000 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 separate from any other wiring. Additional noise

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

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 1000 system.

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 earth ground the drain wire and foil shield at both ends of the cable.

Wiring Your Controller for High-Speed Counter Applications

To wire the controller for high-speed counter applications, use input terminals I/0, I/1, I/2, and I/3. Refer to chapter 14 for information on using the high-speed counter.

Shielded cable is required for high-speed input signals 0–3 when the filter setting is set to either 0.10 ms or 0.075 ms. We recommend Belden #9503 for lengths up to 305 m (1000 ft). Shields should be grounded only at the signal source end of the cable. Ground the shield to the case of the signal source, so energy coupled to the shield is not delivered to the signal source’s electronics.

Chapter

Connecting the System

This chapter describes how to wire your controller system. The method you use and cabling required to connect your controller depends on what type of system you are employing. Specifically, this chapter contains information on:

• connecting the HHP

• DH-485 connections

• establishing communication

Important: In order to access the functionality of the Series C or later

discrete and all MicroLogix 1000 analog controllers, you must configure your program to operate with these controllers. See page 18–18 for more information.

Connecting

the HHP

Use a serial cable to connect the MicroLogix 1000 HHPs RS-232 communication channel to the MicroLogix 1000 programmable controller, as shown below.

ATTENTION: Chassis ground, user 24V ground, and RS-232 ground are internally connected. You must connect the chassis

ground terminal screw to chassis ground prior to connecting any devices. It is important that you understand your programming device’s grounding system before connecting to the controller.

Recommended Tools

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

Description Part Number Manufacturer

Shielded Twisted Pair Cable #3106A or #9842 Belden Stripping Tool 45-164 Ideal Industries 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.

3–3

Chapter 3

Connecting the System

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).

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. (If you are using standard Allen-Bradley cables, see the Cable Selection Guide on page 3–8.)

Powering the AIC+

ATTENTION: If you use an external power supply, it must be 24V dc. Permanent damage will result if miswired with the

wrong power source.

Set the DC Power Source selector switch to EXTERNAL before connecting the power supply to the AIC+.

Bottom View

ATTENTION: 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.

In normal operation with the MicroLogix 1000 programmable controller connected to port 2 of the AIC+, the controller powers the AIC+. Any AIC+ not connected to a controller requires a 24V dc power supply. The AIC+ requires 85 mA at 24V dc.

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

Power Options

Below are two options for powering the AIC+:

• Use the 24V dc user power supply (200 mA maximum) built into the

MicroLogix 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 +20% / –15% – output current: 120 mA minimum –

rated NEC

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

3–11

Chapter 3

Connecting the System

ATTENTION: If you use an external power supply, it must be 24V dc. Permanent damage will result if miswired with the

wrong power source.

Installing and Attaching the AIC+

1. Take care when installing the AIC+ in an enclosure so that the cable

connecting the MicroLogix 1000 controller to the AIC+ does not interfere with the enclosure door.

2. Carefully plug the terminal block into the DH-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.

Establishing Communication

When you connect a MicroLogix 1000 controller, it automatically determines which protocol is active (DF1 or DH-485), and establishes communication accordingly. Therefore, no special configuration is required to connect to either network.

However, to shorten the connection time, you can specify which protocol the controller should attempt to establish communication with first. This is done using the Primary Protocol bit, S:0/10. The default setting for this bit is DF1 (0). If the primary protocol bit is set to DF1, the MicroLogix 1000 controller will attempt to connect using the configured DF1 protocol: either full-duplex or half-duplex slave. To have the controller first attempt DH-485 communication, set this bit to 1.

For DH-485 networks that will only contain MicroLogix controllers, at least one controller must have its primary protocol bit set to 1 so that the network can be initialized.

3–12

Interfac

Chapter 3

Connecting the System

Automatic

Protocol Switching

The MicroLogix 1000 Series D or later discrete and all MicroLogix 1000 analog controllers perform automatic protocol switching between DH-485 and the configured DF1 protocol. (The controller cannot automatically switch between DF1 full-duplex and DF1 half-duplex slave.) This feature allows you to switch from active communication on a DF1 half-duplex network to the DH-485 protocol to make program changes.

Simply disconnect the MicroLogix controller from the DF1 half-duplex network and connect it to your personal computer. The controller recognizes the computer is attempting to communicate using the DH-485 protocol and automatically switches to it. When your program changes are complete, you can disconnect your computer, reconnect the modem, and the controller automatically switches back to the configured DF1 protocol. For example, if you are using the DH-485 protocol to make program changes and you connect an HHP, you can switch to active communication on a DF1 full-duplex network.

The following baud rate limitations affect autoswitching:

• If the configured DH-485 baud rate is 19200, the configured DF1 baud

rate must be 4800 or greater.

• If the configured DH-485 baud rate is 9600, the configured DF1 baud rate

must be 2400 or greater.

DeviceNet Communications

You can also connect a MicroLogix to a DeviceNet network using the DeviceNet Interface (DNI), catalog number 1761-NET-DNI. For additional information on connecting the DNI, see the Advanced Interface Converter (AIC+) and DeviceNet Interface (DNI) Installation Instructions, Publication 1761-5.11. For information on how to configure and commission a DNI, see the DeviceNet Interface User Manual, Publication 1761-6.5.

Identifying the Power-Up Sequence

When the MicroLogix 1000 HHP is first connected to the controller, the following sequence occurs:

1. The HHP performs diagnostic self tests. While doing this it displays the

following Copyright screens:

I C R O P R O G R A M M E R

V E R S I O N X . X X

A L L E N - B R A D L E Y C O

C O P Y R I G H T 1 9 9 4

A L L R I G H T S

R E S E R V E D

These screens will always appear in English, even if you later select an alternate language for the HHP.

2. The HHP begins connecting to the controller and displays:

C O N N E C T I N G . . .

The HHP automatically finds the controller’s baud rate and connects to it at that rate.

3. After a successful connection, the HHP displays the home screen.

For discrete controllers:

C R O R P R G

F R E E : 7 3 7 FIL E : 0 2

For analog controllers:

Monitoring Operation

You can monitor the operation of your program by viewing the program files and the data files.

Monitoring the Program

You should now be running the program MICRO. You can test the operation of your program by monitoring the relay instruction states. Instruction state boxes appear to the right of each bit instruction. When filled, these boxes indicate that logical continuity exists in the program.

1. From the home screen, access the program monitor.

R 0 0 1

O / 1 0

You return to the last location you were at within the program. The instructions will either be on or off, depending on the input and output states in your program.

2. Arrow back to bit I/6 on rung 0 of the program. As you do this, look at

the instruction state boxes and see which ones, if any, are filled.

Chapter

Programming Overview

This chapter explains how to use the MicroLogix 1000 HHP to program the micro controller. Read this chapter for basic information about:

• principles of machine control

• understanding file organization

• understanding how programs are stored and accessed

• addressing data files

• applying logic to your schematics

• a model for developing your program

Principles

of Machine Control

The controller consists of a built-in power supply, central processing unit (CPU), inputs, which you wire to input devices (such as push buttons, proximity sensors, limit switches), and outputs, which you wire to output devices (such as motor starters, solid-state relays, and indicator lights).

Micro Controller

You enter a logic program into the controller using the HHP. The logic program is based on your electrical relay print diagrams. It contains instructions that direct control of your application.

6–1

Chapter 6

Programming Overview

With the logic program entered into the controller, placing the controller in the Run mode initiates an operating cycle. The controller’s operating cycle consists of a series of operations performed sequentially and repeatedly, unless altered by your program logic.

 program scan – the time required for the controller to execute the

instructions in the program. The program scan time varies depending on the instructions used and each instruction’s status during the scan time.

Important:Subroutine and interrupt instructions within your logic

program may cause deviations in the way the operating cycle is sequenced.

 output scan – the time required for the controller to scan and write all

output data; typically accomplished within µseconds.

 service communications – the part of the operating cycle in which

communication takes place with other devices, such as a MicroLogix 1000 HHP or a personal computer.

 housekeeping and overhead – time spent on memory management and

updating timers and internal registers.

Chapter 6

Programming Overview

Understanding Organization

File

The micro controller provides control through the use of a program. Most of the operations you perform with the MicroLogix 1000 HHP involve the program and the two components created with it: program files and data files.

Program

Data FilesProgram Files

(14 Maximum)

(8 Maximum)

Notes on terminology: The term program used in HHP displays is equivalent to the term processor file that may be used in some programming software packages.

Program

A program consists of the collective program files and data files. It contains all the instructions, data, and configuration information pertaining to that program.

The program is located in the micro controller. It can be transferred to/from a memory module (optional) located in the HHP, or to/from a personal computer with programming software.
