Communication Options

The MicroLogix 1200 can be connected to a personal computer. It can also be connected to a DH-485 network, or a Modbus network as an

RTU Master or RTU Slave using an Advanced Interface Converter

(catalog number 1761-NET-AIC) and to the DeviceNet network using a DeviceNet Interface (catalog number 1761-NET-DNI). The controller can also be connected to DF1 Half-duplex networks as an RTU Master or RTU Slave. Series B controllers may also be connected to serial devices using ASCII.

See Chapter 4 Communication Connections for more information on

connecting to the available communication options.

The 1762-LxxxxxR controllers provide an additional communication port called the Programmer/HMI Port. This port supports DF1 full-duplex protocol only. The controller cannot initiate messages through this port. It can only respond to messages sent to it. All communication parameters are fixed and cannot be changed by a user.

See Default Communication Configuration on page 4-2 for the

configuration settings.

ATTENTION

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

Safety Considerations

ATTENTION

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.

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.

Disconnect Main Power

WARNING

Explosion Hazard

Do not replace components 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

WARNING

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.

Power Considerations

Install Your Controller 2-5

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.

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).

Publication 1762-UM001E-EN-P - February 2006

2-6 Install Your Controller

Power Supply Inrush

During power-up, the MicroLogix 1200 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 1200 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. This is referred to as a power supply shutdown. The processor then performs an orderly shutdown of the controller.

Publication 1762-UM001E-EN-P - February 2006

Install Your Controller 2-7

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.

Prevent 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.

TIP

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 1762-UM001E-EN-P - February 2006

2-8 Install Your Controller

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 2-10 and 2-11.

ATTENTION

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

TIP

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 1762-UM001E-EN-P - February 2006

Install Your Controller 2-9

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.

Use 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.

TIP

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.

ATTENTION

During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire stands) is kept from falling into the module. Debris that falls into the module could cause damage when the module is under power.

DIN Rail Mounting

The module can be mounted using the following DIN rails:

• 35 x 7.5 mm (EN 50 022 - 35 x 7.5), or

• 35 x 15 mm (EN 50 022 - 35 x 15).

Before mounting the module on a DIN rail, close the DIN rail latch.

Press the DIN rail mounting area of the module against the DIN rail.

The latch momentarily opens and locks into place.

Connect Expansion I/O

Install Your Controller 2-19

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.

Pull Loop

TIP

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

TIP

Up to six expansion I/O modules can be connected to a controller depending upon the power supply loading.

ATTENTION

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.

WARNING

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 2-19. If DIN rail mounting is used, an

end stop must be installed ahead of the controller and after the last 1762 I/O module.

Wire Your Controller

Wire Requirements

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

• expansion I/O wiring

ATTENTION

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

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.

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.

Publication 1762-UM001E-EN-P - February 2006

3-2 Wire Your Controller

TIP

Do not run signal or communication 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.

Wire without Spade Lugs

When wiring without spade lugs, it is recommended to keep the finger-safe covers in place. Loosen the terminal screw and route the wires through the opening in the finger-safe cover. Tighten the terminal screw making sure the pressure plate secures the wire.

Finger-Safe Cover

Publication 1762-UM001E-EN-P - February 2006

Wire Your Controller 3-3

Wire with Spade Lugs

The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and output terminals of the MicroLogix 1200 controller are designed for a 6.35 mm (0.25 in.) wide spade (standard for #6 screw for up to 14 AWG) or a 4 mm (metric #4) fork terminal.

When using spade lugs, use a small, flat-blade screwdriver to pry the finger-safe cover from the terminal blocks as shown below. Then loosen the terminal screw.

Use 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.

Publication 1762-UM001E-EN-P - February 2006

The following diagram shows an output with a suppression 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 suppressor can also be used. See Table 3.2 for

recommended suppressors. As shown below, these surge suppression circuits connect directly across the load device.

3-6 Wire Your Controller

Ground the Controller

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.

ATTENTION

All devices connected to the RS-232 channel 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 1762-L24BWA, 1762-L40BWA, 1762-L24BWAR, and 1762-L40BWAR 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 1762-L24BXB, 1762-L40BXB, 1762-L24BXBR, and 1762-L40BXBR controllers:

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

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.

TIP

Use all four mounting positions for panel mounting installation.

Publication 1762-UM001E-EN-P - February 2006

Grounding Stamping

ATTENTION

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

Wiring Diagrams

Wire Your Controller 3-7

The following illustrations show the wiring diagrams for the

MicroLogix 1200 controllers. Controllers with dc inputs can be wired as either sinking or sourcing inputs. (Sinking and sourcing does not

apply to ac inputs.) Refer to Sinking and Sourcing Wiring Diagrams on page 3-11

The controller terminal block layouts are shown below. The shading on the labels indicates how the terminals are grouped. A detail of the groupings is shown in the table following the terminal block layouts.

TIP

This symbol denotes a protective earth ground terminal which provides a low impedance path between electrical circuits and earth for safety purposes and provides noise immunity improvement. This connection must be made for safety purposes on ac-powered controllers.

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.

Minimize 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 1200 system in a properly rated (NEMA) enclosure. Make sure that the

MicroLogix 1200 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 1200 system.

The following sections show the discrete and analog expansion I/O wiring diagrams.

Analog Wiring

System Wiring Guidelines

Consider the following when wiring your analog modules:

• The analog common (COM) is not connected to earth ground inside the module. All terminals are electrically isolated from the system.

• 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.

• The module does not provide loop power for analog inputs. Use a power supply that matches the input transmitter specifications.

1762-IF2OF2 Input Type Selection

Select the input type, current or voltage, using the switches located on the module’s circuit board and the input type/range selection bits in the Configuration Data File. Refer to MicroLogix 1200 and 1500

Programmable Controllers Instruction Set Reference Manual, publication number 1762-RM001. You can access the switches through the ventilation slots on the top of the module. Switch 1 controls channel 0; switch 2 controls channel 1. The factory default setting for both switch 1 and switch 2 is Current. Switch positions are shown below.

1762-IF2OF2 Output Type Selection

The output type selection, current or voltage, is made by wiring to the appropriate terminals, Iout or Vout, and by the type/range selection bits in the Configuration Data File. Refer to MicroLogix 1200 and 1500

Programmable Controllers Instruction Set Reference Manual, publication number 1762-RM001.

ATTENTION

Analog outputs may fluctuate for less than a second when power is applied or removed. This characteristic is common to most analog outputs.

While the majority of loads will not recognize this short signal, it is recommended that preventive measures be taken to ensure that connected equipment is not affected.

Grounding the cable shield at the module end only usually provides sufficient noise immunity.

However, for best cable shield performance, earth ground the shield at both ends, using a 0.01µF capacitor at one end to block AC power ground currents, if necessary.

Communication Connections

Introduction

This chapter describes how to communicate to 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 push button

• connecting to RS-232 port

• connecting to DH-485 network

• connecting to AIC+

• DeviceNet communications

MicroLogix 1200 controllers with the additional communications port

(1762-L24AWAR, 1762-L24BWAR, 1762-L24BXBR, 1762-L40AWAR,

1762-L40BWAR, 1762-L40BXBR) offer advanced communications options, providing a clean, cost effective solution for applications requiring a network connection and HMI.

The additional communications port (Programmer/HMI Port) enables two communication devices to be connected to the controller simultaneously. For example, it provides local connectivity of an operator interface or programming terminal such as DF1 PanelView

HMI, IBM-compatible personal computer using RSLogix 500 programming software, or 1747-PSD program storage device, and also allows the primary port (Channel 0) to be connected to either a network, a modem, or an ASCII device such as a barcode reader or weigh scale.

Supported Communication

Protocols

MicroLogix 1200 controllers support the following communication protocols from the primary RS-232 communication channel,

Channel 0:

• DH-485

• DF1 Full-duplex

• DF1 Half-duplex

• DF1 Radio Modem

• Modbus Master and Slave

• ASCII

Publication 1762-UM001E-EN-P - February 2006

4-2 Communication Connections

The 1762-L24AWAR, 1762-L24BWAR, 1762-L24BXBR, 1762-L40AWAR,

1762-L40BWAR, and 1762-L40BXBR controllers are equipped with an additional RS-232 communication channel called the Programmer/HMI

Port, which supports DH Full-duplex only. The controller cannot initiate messages through this port. It can only respond to messages sent to it. All communication parameters are fixed and cannot be changed by a user.

See Default Communication Configuration on page 4-2 for the

configuration settings.

For more information on MicroLogix 1200 communications, refer to the MicroLogix 1200 and MicroLogix 1500 Programmable Controllers

Instruction Set Reference Manual, publication number 1762-RM001.

Default Communication

Configuration

The MicroLogix 1200 has the following default communication configuration. The same default configuration is applied for both

Channel 0 and the Programmer/HMI Port (for 1762-LxxxxxR only).

The configurations for the Programmer/HMI Port are fixed and you cannot change them.

TIP

For Channel 0, the default configuration is present when:

• The controller is powered-up for the first time.

• The communications toggle push button specifies default communications (the DCOMM LED is on).

• An OS upgrade is completed.

See Appendix E for more information about communicating.

The Communications toggle push button is located on the processor under the processor door (if installed), as shown below.

Use the Communications toggle push button to change from the user-defined communication configuration to the default communications mode and back on Channel 0. The parameters of the

Programmer/HMI Port are fixed at the default communications configuration. The Default Communications (DCOMM) LED operates to show when the controller is in the default communications mode

(settings shown on page 4-2).

4-4 Communication Connections

Connect to the RS-232 Port

There are two ways to connect the MicroLogix 1200 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.

ATTENTION

All devices connected to the RS-232 channel 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 1762-L24BWA, 1762-L40BWA, 1762-L24BWAR and 1762-L40BWAR 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 1762-L24BXB, 1762-L40BXB, 1762-L24BXBR and 1762-L40BXBR controllers:

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

Recommended Tools

To connect a DH-485 network, 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):

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.

Publication 1762-UM001E-EN-P - February 2006

4-10 Communication Connections

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-UM004.

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 4-14 if you are using standard

Allen-Bradley cables.)

Connect the Communication Cable to the DH-485 Connector

Ground and Terminate 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+ as required by the DH-485 specification.

The AIC+, catalog number 1761-NET-AIC, enables a MicroLogix 1200 to connect to a DH-485 network. The AIC+ has two RS-232 ports and one isolated RS-485 port. Typically, there is one AIC+ for each

MicroLogix 1200. When two MicroLogix controllers are closely positioned, you can connect a controller to each of the RS-232 ports on the AIC+.

The AIC+ can also be used as an RS-232 isolator, providing an isolation barrier between the MicroLogix 1200 communications port and any equipment connected to it (for example a personal computer or modem).

Safety Considerations

This equipment is suitable for use in Class I, Division 2, Groups A, B,

C, D or non-hazardous locations only.

WARNING

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 2-3 for additional information.

Publication 1762-UM001E-EN-P - February 2006

4-18 Communication Connections

Install and Attach the AIC+

1. Take care when installing the AIC+ in an enclosure so that the cable connecting the MicroLogix 1200 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.

Apply Power to the AIC+

In normal operation with the MicroLogix 1200 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 120 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+.

ATTENTION

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+.

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.

Power Options

Below are two options for powering the AIC+:

• Use the 24V dc user power supply built into the MicroLogix

1200 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+.

ATTENTION

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

Trim Pot Operation

Chapter

5

Use Trim Pots

The processor has two trimming potentiometers (trim pots) which allow modification of data within the controller. Adjustments to the trim pots change the value in the corresponding Trim Pot Information

(TPI) register. The data value of each trim pot can be used throughout the control program as timer, counter, or analog presets depending upon the requirements of the application.

The trim pots are located below the memory module port cover and to the right of the communications port, as shown below.

Trim Pot 0

Trim Pot 1

COM

Use a small flathead screwdriver to turn the trim pots. Adjusting their value causes data to change within a range of 0 to 250 (fully clockwise). The maximum rotation of each trim pot is three-quarters, as shown below. Trim pot stability over time and temperature is typically ±2 counts.

Real-time Clock Operation

The following sections cover:

• Removal/Insertion Under Power

• Write Data to the Real-time Clock

• RTC Battery Operation

Removal/Insertion Under Power

At power-up and when the controller enters a run or test mode, the controller determines if a real-time clock module (RTC) is present. If an RTC is present, its values (date, time and status) are written to the

RTC Function File in the controller.

The RTC module can be installed or removed at any time without risk of damage to either the module or the controller. If an RTC is installed while the MicroLogix 1200 is in a run or test mode, the module is not recognized until either a power cycle occurs or until the controller is placed in a non-executing mode (program mode, suspend mode or fault condition).

Publication 1762-UM001E-EN-P - February 2006

6-2 Use Real-time Clock and Memory Modules

Removal of the RTC during run mode is detected within one program scan. Removal of the RTC while in run mode causes the controller to write zeros to the RTC Function File.

The following table indicates the accuracy of the RTC for various temperatures.

Table 6.1 RTC Accuracy

+34 … -70 seconds/month

+36 … -68 seconds/month

+29 … -75 seconds/month

-133 … -237 seconds/month

(1) These numbers are maximum worst case values over a 31-day month.

Write Data to the Real-time Clock

When valid data is sent to the real-time clock from the programming device or another controller, the new values take effect immediately.

The real-time clock does not recognize or accept invalid date or time data.

Use the Disable Clock button in your RSLogix programming software to disable the real-time clock before storing a module. This decreases the drain on the RTC battery during storage.

RTC Battery Operation

The real-time clock has an internal battery that is not replaceable. The

RTC Function File features a battery low indicator bit (RTC:0/BL), which shows the status of the RTC battery. When the battery is low, the indicator bit is set (1). This means that the battery may fail within

14 days and the real-time clock module needs to be replaced. When the battery low indicator bit is clear (0), the battery level is acceptable or a real-time clock is not attached.

If the RTC battery is low and the controller is powered, the RTC operates normally. If the controller power is removed and the RTC battery is low, RTC data is lost.

ATTENTION

Operating with a low battery indication for more than 14 days may result in invalid RTC data unless power is on continuously.

Memory Module Operation

The memory module supports the following features:

• User Program and Data Back-up

• User Program Compare

• Data File Download Protection

• Memory Module Write Protection

• Removal/Insertion Under Power

ATTENTION

Electrostatic discharge can damage the Memory

Module. Do not touch the connector pins or other sensitive areas.

User Program and Data Back-up

The memory module provides a simple and flexible program/data transport mechanism, allowing the user to transfer the program and data to the controller without the use of a personal computer and programming software.

The memory module can store one user program at a time.

During program transfers to or from the memory module, the controller’s RUN LED flashes.

6-4 Use Real-time Clock and Memory Modules

Publication 1762-UM001E-EN-P - February 2006

Program Compare

The memory module can also provide application security, allowing you to specify that if the program stored in the memory module does not match the program in the controller, the controller will not enter an executing (run or test) mode. To enable this feature, set the S:2/9 bit in the system status file. See ‘Status System File’ in the MicroLogix

1200 and 1500 Programmable Controllers Instruction Set Reference

Manual, Publication 1762-RM001 for more information.

Data File Download Protection

The memory module supports data file download protection. This allows user data to be saved (not overwritten) during a download.

TIP

Data file download protection is only functional if the processor does not have a fault, size of all protected data files in the memory module exactly match the size of protected data files within the controller, and all protected data files are of the same type. See

‘Protecting Data Files During Download’ in the

MicroLogix 1200 and 1500 Programmable Controllers

Instruction Set Reference Manual, publication

1762-RM001.

Memory Module Write Protection

The memory module supports write-once, read-many behavior. Write protection is enabled using your programming software.

IMPORTANT

Once set, write protection cannot be removed. A change cannot be made to the control program stored in a write protected memory module. If a change is required, use a different memory module.

Removal/Insertion Under Power

The memory module can be installed or removed at any time without risk of damage to either the memory module or the controller. If a memory module is installed while the MicroLogix 1200 is executing, the memory module is not recognized until either a power cycle occurs, or until the controller is placed in a non-executing mode

(program mode, suspend mode or fault condition).

(1) Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O module and the field device. Sourcing I/O circuits supply (source) current to sinking field devices. Sinking I/O circuits are driven by a current sourcing field device. Field devices connected to the negative side (DC Common) of the field power supply are sinking field devices. Field devices connected to the positive side (+V) of the field supply are sourcing field devices.

Troubleshooting

Module Operation and Channel Operation

The module performs operations at two levels:

• module level

• channel level

Module-level operations include functions such as power-up, configuration, and communication with the controller.

Internal diagnostics are performed at both levels of operation. Both module hardware and channel configuration error conditions are reported to the controller. Channel over-range or under-range conditions are reported in the module’s input data table. Module hardware errors are reported in the controller’s I/O status file. Refer to the MicroLogix 1200 and 1500 Programmable Controllers Instruction

Set Reference Manual, publication 1762-RM001 for more information.

When a fault condition is detected, the analog outputs are reset to zero.

Power-up Diagnostics

At module power-up, a series of internal diagnostic tests are performed.

Critical and Noncritical Errors

Noncritical module errors are recoverable. Channel errors (over-range or under-range errors) are noncritical. Noncritical error conditions are indicated in the module input data table. Noncritical configuration errors are indicated by the extended error code.

See Table C.5 on page C-7.

Critical module errors are conditions that prevent normal or recoverable operation of the system. When these types of errors occur, the system leaves the run mode of operation.

Critical module errors are indicated in Table C.5 on page C-7.

Module Error Definition Table

Analog module errors are expressed in two fields as four-digit Hex format with the most significant digit as ‘don’t care’ and irrelevant. The two fields are ‘Module Error’ and ‘Extended Error Information’. The structure of the module error data is shown below.

Module Error Field

The purpose of the module error field is to classify module errors into three distinct groups, as described in the table below. The type of error determines what kind of information exists in the extended error information field. These types of module errors are typically reported in the controller’s I/O status file. Refer to the MicroLogix 1200 and

1500 Programmable Controllers Instruction Set Reference Manual, publication 1762-RM001 for more information.

Use Control Flash to Upgrade Your Operating

System

1

Prepare for Upgrade

The operating system (OS) can be upgraded through the communication port on the controller. In order to download a new operating system, you must have the following:

• ControlFlash Upgrade Kit containing the new OS

Go to http://www.ab.com/micrologix to download the upgrade kit.

• a Windows 95, Windows 98, Windows 2000 or

Windows NT based computer to run the download software.

The ControlFlash Upgrade Kit includes:

• the operating system upgrade to be downloaded

• the ControlFlash programming tool, along with its support drivers and on-line help

• a readme first file explaining how to upgrade the operating system

Before upgrading the controller’s operating system, you must:

• install ControlFlash software on your personal computer

• prepare the controller for updating

IMPORTANT

Installing a new operating system deletes the user program. After the operating system upgrade is successful, you must transfer your control program back to the controller. The communication

parameters are described on Table 4.1 on page 4-2.

Install ControlFlash Software

For 1762-Lxxxxx controllers, double click the 1762-LSC-FRNxx.exe file to install the operating system upgrade (where xx is the firmware revision number).

Publication 1762-UM001E-EN-P - February 2006

D-2 Use Control Flash to Upgrade Your Operating System

For 1762-LxxxxxR controllers, double click the 1762-LRC-FRNxx.exe file to install the operating system upgrade.

Prepare the Controller for Updating

Controller Configuration

The controller must be configured for default communications (use communications toggle push button; DCOMM LED on) and be in the

Program mode to allow the download of a new operating system.

Sequence of Operation

The following steps detail the key events in the upgrade process.

1. Controller mode and communications parameters are checked.

2. Download begins.

3. During the download, the Force, Battery, and Comms LEDs perform a walking bit pattern.

4. When the download is complete, the integrity of the new OS is checked. If the new OS is corrupt, the controller sends an error message to the download tool and flashes the Missing or

Corrupt OS LED pattern. See Missing/Corrupt OS LED Pattern

below.

5. Following a successful transfer, the Power, Force, and Battery

LEDs flash on and remain on for five seconds. Then the controller resets.

Missing/Corrupt OS LED

Pattern

When an operating system download is not successful or if the controller does not contain a valid operating system, the controller flashes the Run, Force, and Fault LEDS on and off.

Connect to Networks via RS-232 Interface

1

The following protocols are supported from the RS-232 communication channel:

• DF1 Full-duplex

• DF1 Half-duplex

• DH-485

• Modbus

• ASCII

RS-232 Communication

Interface

The communications port on the MicroLogix 1200 utilizes an RS-232 interface. RS-232 is an Electronics Industries Association (EIA) standard that specifies the electrical and mechanical characteristics for serial binary communication. It provides you with a variety of system configuration possibilities. (RS-232 is a definition of electrical characteristics; it is not a protocol.)

One of the biggest benefits of an RS-232 interface is that it lets you integrate telephone and radio modems into your control system (using the appropriate DF1 protocol only, not DH-485 protocol).

DF1 Full-duplex Protocol

DF1 Full-duplex protocol provides a point-to-point connection between two devices. DF1 Full-duplex protocol combines data transparency (American National Standards Institute ANSI - X3.28-1976 specification subcategory D1) and 2-way simultaneous transmission with embedded responses (subcategory F1).

The MicroLogix 1200 controllers support the DF1 Full-duplex protocol via RS-232 connection to external devices, such as computers, or other controllers that support DF1 Full-duplex.

DF1 is an open protocol. Refer to DF1 Protocol and Command Set

Reference Manual, publication 1770-6.5.16, for more information.

DF1 Full-duplex protocol (also referred to as DF1 point-to-point protocol) is useful where RS-232 point-to-point communication is required. DF1 protocol controls message flow, detects and signals errors, and retries if errors are detected.

DF1 Half-duplex Protocol

DF1 Half-duplex protocol is a multi-drop single master/multiple slave network. DF1 Half-duplex protocol supports data transparency

(American National Standards Institute ANSI - X3.28-1976 specification subcategory D1). In contrast to DF1 Full-duplex, communication takes place in one direction at a time. You can use the RS-232 port on the

MicroLogix 1200 as both a Half-duplex programming port and a

Half-duplex peer-to-peer messaging port.

MicroLogix 1200 can act as the master or as a slave on a Half-duplex network. When the MicroLogix 1200 is a slave device, a master device is required to ‘run’ the network. Several other Allen-Bradley products support DF1 Half-duplex master protocol. They include the SLC 5/03 and higher processors, enhanced PLC-5 processors and Rockwell

Software RSLinx (version 2.x and higher).

DF1 Half-duplex supports up to 255 devices (address 0 to 254) with address 255 reserved for master broadcasts. As a DF1 Half-duplex slave device, the MicroLogix 1200 supports broadcast reception. As a

DF1 Half-duplex master, the MicroLogix 1200 supports both the reception and initiation of broadcast write commands (via the MSG instruction). The MicroLogix 1200 also supports Half-duplex modems using RTS/CTS hardware handshaking.

Use Modems with MicroLogix 1200 Programmable Controllers

The types of modems you can use with MicroLogix 1200 controllers include the following:

• dial-up phone modems

A MicroLogix 1200 controller, on the receiving end of the dial-up connection, can be configured for DF1 Full-duplex protocol with or without handshaking. The modem connected to the

MicroLogix controller should support auto-answer. The

MicroLogix 1200 supports ASCII out communications. Therefore, it can cause a modem to initiate or disconnect a phone call.

• leased-line modems

Leased-line modems are used with dedicated phone lines that are typically leased from the local phone company. The dedicated lines may be in a point-to-point topology supporting

Full-duplex communications between two modems or in a multi-drop topology supporting Half-duplex communications between three or more modems.

Publication 1762-UM001E-EN-P - February 2006

E-4 Connect to Networks via RS-232 Interface

• radio modems

Radio modems may be implemented in a point-to-point topology supporting either Half-duplex or Full-duplex communications, or in a multi-drop topology supporting

Half-duplex communications between three or more modems.

MicroLogix 1200 also supports DF1 Radio Modem protocol.

• line drivers

Line drivers, also called short-haul modems, do not actually modulate the serial data, but rather condition the electrical signals to operate reliably over long transmission distances (up to several miles). Line drivers are available in Full-duplex and

Half-duplex models. Allen-Bradley’s AIC+ Advanced Interface

Converter is a Half-duplex line driver that converts an RS-232 electrical signal into an RS-485 electrical signal, increasing the signal transmission distance from 50 to 4000 feet (8000 feet when bridged).

For point-to-point Full-duplex modem connections that do not require any modem handshaking signals to operate, use DF1 Full-duplex protocol with no handshaking. For point-to-point Full-duplex modem connections that require RTS/CTS handshaking, use DF1 Full-duplex protocol with handshaking.

For radio modem connections, use DF1 Radio Modem protocol, especially if store and forward capability is required.

For general multi-drop modem connections, or for point-to-point modem connections that require RTS/CTS handshaking, use DF1

Half-duplex slave protocol. In this case, one (and only one) of the other devices must be configured for DF1 Half-duplex master protocol.

IMPORTANT

Never attempt to use DH-485 protocol through modems under any circumstance.

TIP

All MicroLogix 1200 controllers support RTS/CTS modem handshaking when configured for DF1

Full-duplex protocol with the control line parameter set to Full-duplex Modem Handshaking or DF1

Half-duplex slave protocol with the control line parameter set to ‘Half-duplex Modem’. No other modem handshaking lines (Data Set Ready, Carrier

Detect and Data Terminal Ready) are supported by any MicroLogix 1200 controllers.

DH-485 Communication

Protocol

The DH-485 protocol defines the communication between multiple devices that coexist on a single pair of wires. DH-485 protocol uses

RS-485 Half-duplex as its physical interface. (RS-485 is a definition of electrical characteristics; it is not a protocol.) RS-485 uses devices that are capable of co-existing on a common data circuit, thus allowing data to be easily shared between devices.

The DH-485 protocol supports two classes of devices: initiators and responders. All initiators on the network get a chance to initiate message transfers. To determine which initiator has the right to transmit, a token passing algorithm is used.

Devices that use the DH-485 Network

In addition to the MicroLogix 1200 controllers, the devices shown in the following table also support the DH-485 network.

Important DH-485 Network Planning Considerations

Carefully plan your network configuration before installing any hardware. Listed below are some of the factors that can affect system performance:

• amount of electrical noise, temperature, and humidity in the network environment

• number of devices on the network

• connection and grounding quality in installation

• amount of communication traffic on the network

• type of process being controlled

• network configuration

The major hardware and software issues you need to resolve before installing a network are discussed in the following sections.

Hardware Considerations

You need to decide the length of the communication cable, where you route it, and how to protect it from the environment where it will be installed.

When the communication cable is installed, you need to know how many devices are to be connected during installation and how many

Publication 1762-UM001E-EN-P - February 2006

Connect to Networks via RS-232 Interface E-7 devices will be added in the future. The following sections help you understand and plan the network.

Number of Devices and Length of Communication Cable

The maximum length of the communication cable is 1219 m (4000 ft).

This is the total cable distance from the first node to the last node in a segment. 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-UM004.

Planning Cable Routes

Follow these guidelines to help protect the communication cable from electrical interference:

• Keep the communication cable at least 1.52 m (5 ft) from any electric motors, transformers, rectifiers, generators, arc welders, induction furnaces, or sources of microwave radiation.

• If you must run the cable across power feed lines, run the cable at right angles to the lines.

• If you do not run the cable through a contiguous metallic wireway or conduit, keep the communication cable at least

0.15 m (6 in.) from ac power lines of less than 20 A, 0.30 m (1 ft) from lines greater than 20 A, but only up to 100 kVA, and 0.60 m

(2 ft) from lines of 100 kVA or more.

• If you run the cable through a contiguous metallic wireway or conduit, keep the communication cable at least 0.08 m (3 in) from ac power lines of less than 20 A, 0.15 m (6 in) from lines greater than 20 A, but only up to 100 kVA, and 0.30 m (1 ft) from lines of 100 kVA or more.

Running the communication cable through conduit provides extra protection from physical damage and electrical interference. If you route the cable through conduit, follow these additional recommendations:

Use ferromagnetic conduit near critical sources of electrical interference. You can use aluminum conduit in non-critical areas.

Use plastic connectors to couple between aluminum and ferromagnetic conduit. Make an electrical connection around the plastic connector (use pipe clamps and the heavy gauge wire or wire braid) to hold both sections at the same potential.

Publication 1762-UM001E-EN-P - February 2006

E-8 Connect to Networks via RS-232 Interface

Ground the entire length of conduit by attaching it to the building earth ground.

Do not let the conduit touch the plug on the cable.

Arrange the cables loosely within the conduit. The conduit should contain only serial communication cables.

Install the conduit so that it meets all applicable codes and environmental specifications.

For more information on planning cable routes, see Industrial

Automation Wiring and Grounding Guidelines, publication Number

1770-4.1.

Software Considerations

Software considerations include the configuration of the network and the parameters that can be set to the specific requirements of the network. The following are major configuration factors that have a significant effect on network performance:

• number of nodes on the network

• addresses of those nodes

• baud rate

The following sections explain network considerations and describe ways to select parameters for optimum network performance (speed).

See your programming software’s user manual for more information.

Number of Nodes

The number of nodes on the network directly affects the data transfer time between nodes. Unnecessary nodes (such as a second programming terminal that is not being used) slow the data transfer rate. The maximum number of nodes on the network is 32.

Setting Node Addresses

The best network performance occurs when node addresses are assigned in sequential order. Initiators, such as personal computers, should be assigned the lowest numbered addresses to minimize the time required to initialize the network. The valid range for the

MicroLogix 1200 controllers is 1 to 31 (controllers cannot be node 0).

The default setting is 1. The node address is stored in the controller

Communications Status file (CS0:5/0 to CS0:5/7).

Publication 1762-UM001E-EN-P - February 2006

Connect to Networks via RS-232 Interface E-9

Setting Controller Baud Rate

The best network performance occurs at the highest baud rate, which is 19200. This is the default baud rate for a MicroLogix 1200 device on the DH-485 network. All devices must be at the same baud rate. This rate is stored in the controller Communications Status file (CS0:5/8 to

CS0:5/15).

Setting Maximum Node Address

Once you have an established network set up and are confident that you will not be adding more devices, you may enhance performance by adjusting the maximum node address of your controllers. It should be set to the highest node address being used.

IMPORTANT

All devices should be set to the same maximum node address.

MicroLogix Remote Packet Support

MicroLogix 1200 controllers can respond and initiate with communications (or commands) that do not originate on the local

DH-485 network. This is useful in installations where communication is needed between DH-485 and DH+ networks.

The example below shows how to send messages from a device on the DH+ network to a MicroLogix controller on the DH-485 network.

This method uses an SLC 5/04 processor as the bridge connection.

When using this method (as shown in the illustration below):

• PLC-5 devices can send read and write commands to MicroLogix

1200 controllers.

• MicroLogix 1200 controllers can respond to MSG instructions received.

• The MicroLogix 1200 controllers can initiate MSG instructions to devices on the DH+ network.

• PC can send read and write commands to MicroLogix 1200 controllers.

• PC can do remote programming of MicroLogix 1200 controllers.

Modbus Communication

Protocol

Modbus is a Half-duplex, master-slave communications protocol. The

Modbus network master reads and writes coils and registers. Modbus protocol allows a single master to communicate with a maximum of

247 slave devices. MicroLogix 1200 controllers support Modbus RTU

Master and Modbus RTU Slave protocol.

For more information on configurating your MicroLogix 1200 controller for Modbus protocol, refer to the MicroLogix 1200 and 1500

Programmable Controllers Instruction Set Reference Manual, publication 1762-RM001. For more information about the Modbus protocol, see the Modbus Protocol Specifications (available from http://www.modbus.org).

ASCII

ASCII provides connection to other ASCII devices, such as bar code readers, weigh scales, serial printers, and other intelligent devices.

You can use ASCII by configuring the RS-232 port, channel 0 for ASCII driver. Refer to the MicroLogix 1200 and MicroLogix 1500

Programmable Controllers Instruction Set Reference Manual, publication 1762-RM001 for detailed configuration information.

System Loading and Heat Dissipation

System Loading Limitations

When you connect MicroLogix accessories and expansion I/O, an electrical load is placed on the controller power supply. This section shows how to calculate the load and validate that the system will not exceed the capacity of the controller power supply.

The following example is provided to illustrate system loading validation. The system validation procedure accounts for the amount of 5V dc and 24V dc current consumed by controller, expansion I/O,

and user-supplied equipment. Use the System Loading Worksheet on page F-3 to validate your specific 24-point controller configuration.

Use the System Loading Worksheet on page F-8 to validate your

specific 40-point controller.

Current consumed by the processor, memory modules, and the real-time clock modules has already been factored into the calculations. A system is valid if the current and power requirements are satisfied.

The use of binary logic in such a way that “0” represents the voltage level normally associated with logic 1 (for example, 0 = +5V, 1 = 0V).

Positive is more conventional (for example, 1 = +5V, 0 = 0V).

Publication 1762-UM001E-EN-P - February 2006

Glossary 6

Publication 1762-UM001E-EN-P - February 2006

network

A series of stations (nodes) connected by some type of communication medium. A network may be made up of a single link or multiple links.

nominal input current

The current at nominal input voltage.

normally closed

Contacts on a relay or switch that are closed when the relay is de-energized or the switch is deactivated; they are open when the relay is energized or the switch is activated. In ladder programming, a symbol that allows logic continuity (flow) if the referenced input is logic “0” when evaluated.

normally open

Contacts on a relay or switch that are open when the relay is de-energized or the switch is deactivated. (They are closed when the relay is energized or the switch is activated.) In ladder programming, a symbol that allows logic continuity (flow) if the referenced input is logic “1” when evaluated.

off-delay time

The OFF delay time is a measure of the time required for the controller logic to recognize that a signal has been removed from the input terminal of the controller. The time is determined by circuit component delays and by any filter adjustment applied.

offline

Describes devices not under direct communication.

offset

The steady-state deviation of a controlled variable from a fixed point.

off-state leakage current

When an ideal mechanical switch is opened (off-state) no current flows through the switch. Practical semiconductor switches, and the transient suppression components which are sometimes used to protect switches, allow a small current to flow when the switch is in the off state. This current is referred to as the off-state leakage current.

To ensure reliable operation, the off-state leakage current rating of a

Glossary 7 switch should be less than the minimum operating current rating of the load that is connected to the switch.

on-delay time

The ON delay time is a measure of the time required for the controller logic to recognize that a signal has been presented at the input terminal of the controller.

one-shot

A programming technique that sets a bit for only one program scan.

online

Describes devices under direct communication. For example, when

RSLogix 500 is monitoring the program file in a controller.

An EIA standard that specifies electrical, mechanical, and functional characteristics for serial binary communication circuits. A single-ended serial communication interface.

Glossary 9

run mode

This is an executing mode during which the controller scans or executes the ladder program, monitors input devices, energizes output devices, and acts on enabled I/O forces.

rung

Ladder logic is comprised of a set of rungs. A rung contains input and output instructions. During Run mode, the inputs on a rung are evaluated to be true or false. If a path of true logic exists, the outputs are made true. If all paths are false, the outputs are made false.

save

To upload (transfer) a program stored in memory from a controller to a personal computer; OR to save a program to a computer hard disk.

scan time

The time required for the controller to execute the instructions in the program. The scan time may vary depending on the instructions and each instruction’s status during the scan.
