System Overview

The module communicates to the controller through the bus interface. The module also receives 5 and 24V DC power through the bus interface.

You can install as many analog modules as your power supply can support. However, the modules may not be located more than eight modules away from the system power supply.

When you cycle power, the module performs a check of its internal circuits, memory, and basic functions. During this time, the module-status OK indicator remains off. If no faults are found during power-cycle diagnostics, the module-status OK indicator is turned on.

After power-cycle checks are complete, the module waits for valid channel-configuration data. If an invalid configuration is detected, the module generates a configuration error. Once a channel is properly configured and enabled, the module begins its conversion process.

Each time an input channel is read, the converted analog data value is tested for an over-range or under-range condition. In addition, the module supports user-configured high and low alarm condition tests for each input channel. If any of these conditions are detected, unique bits are set in the input-channel status word.

Publication 1769-UM019A-EN-P - October 2008 11

Chapter 1 Overview

Each time a new output value is sent to the module, it is tested for an over-range or under-range condition. In addition, the module supports user-configured high and low output clamps for each output channel. If any of these conditions are detected, unique bits are set in the output-channel status word.

The channel status words are described in the Input Data File

page 36.

The controller uses two’s complement binary data when communicating with the module. This typically occurs at the end of the program scan or when commanded by the control program. If the controller and the module determine that the bus data transfer was made without error, the input data is used in your control program and the output data is used by the module.

No field calibration is required.

Chapter 2 Installation and Wiring

Hazardous Location Considerations

This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or nonhazardous locations only. The following attention statement applies to use in hazardous locations.

ATTENTION

EXPLOSION HAZARD

• Substitution of components may impair suitability for Class I,

Division 2.

• Do not replace components or disconnect equipment unless

power has been switched off or the area is known to be nonhazardous.

• Do not connect or disconnect components unless power has

been switched off or the area is known to be nonhazardous.

• This product must be installed in an enclosure.

• All wiring must comply with N.E.C. article 501-4(b).

Prevent Electrostatic Discharge

ATTENTION

Electrostatic discharge can damage integrated circuits or semiconductors if you touch analog I/O module bus-connector pins or the terminal block on the input module. Follow these guidelines when you handle the module:

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the bus connector or connector pins.

• Do not touch circuit components inside the module.

• Use a static-safe work station, if available.

• Keep the module in its static-shield box, when it is not in use.

14 Publication 1769-UM019A-EN-P - October 2008

Remove Power

Installation and Wiring Chapter 2

ATTENTION

Remove power before removing or inserting this 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 unintended machine motion.

• causing an explosion in a hazardous environment.

Electrical arcing causes excessive wear to contacts on both the module and its mating connector and may lead to premature failure.

Reduce Noise

Most applications require installation in an industrial enclosure to reduce the effects of electrical interference. Analog inputs and outputs are highly susceptible to electrical noise. Electrical noise coupled to the analog inputs and outputs reduces the performance (accuracy) of the module.

Group your modules to minimize adverse effects from radiated electrical noise and heat. Consider the following conditions when selecting a location for the analog module. Position the module:

• away from sources of electrical noise such as hard-contact

switches, relays, and AC motor drives.

• away from modules that generate significant radiated heat, such

as the 1769-IA16 module. Refer to the module’s heat dissipation specification.

In addition, route shielded, twisted-pair analog input wiring away from any high-voltage I/O wiring.

Protecting the Circuit Board from Contamination

The printed circuit board of the module must be protected from dirt, oil, moisture, and other airborne contaminants. To protect the board, the system must be installed in an enclosure suitable for the environment. The interior of the enclosure should be kept clean and the enclosure door should be kept closed whenever possible.

Publication 1769-UM019A-EN-P - October 2008 15

Chapter 2 Installation and Wiring

Assemble the Compact I/O System

The module can be attached to the controller or an adjacent I/O module before or after mounting.

For mounting instructions, see Panel Mounting By Using the

Dimensional Template on page 18, or Mount to a DIN Rail on page

19. To work with a system that is already mounted, see Replace a Single Module Within a System on page 19.

1. Disconnect power.

2. Check that the bus lever of the module to be installed is in the

unlocked (fully right) position.

6. To allow communication between the controller and module,

move the bus lever fully to the left (4) until it clicks.

Make sure it is locked firmly in place.

Mounting the Module

ATTENTION

When attaching I/O modules, it is very important that the bus connectors are securely locked together to be sure of proper electrical connection.

7. Attach an end cap terminator (5) to the last module in the

system by using the tongue-and-groove slots as before.

8. Lock the end cap bus terminator (6).

IMPORTANT

A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end of the bus.

Modules may be mounted to a panel or to a DIN rail.

ATTENTION

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

Minimum Spacing

Maintain spacing from enclosure walls, wireways, or adjacent equipment. Allow 50 mm (2 in.) of space on all sides for adequate ventilation.

Mount to a Panel

Mount the module to a panel by using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every module.

Panel Mounting By Using the Dimensional Template

Locate holes every 17.5 mm (0.689 in.) to allow for a mix of single-wide and one-and-a-half-wide modules (for example, the 1769-OA16 module).

Spacing for one-and-a-half-wide modules 52.5 mm (2.067 in.).

Spacing for single-wide modules 35 mm (1.378 in.).

Refer to host controller documentation for this dimension.

Overall hole spacing tolerance: ±0.4 mm (0.016 in.).

Panel Mounting By Using the Modules as a Template

This procedure lets you use the assembled modules as a template for drilling holes in the panel. If you have sophisticated panel-mounting equipment, you can use the dimensional template provided. Due to module mounting-hole tolerance, it is important to follow these procedures.

1. On a clean work surface, assemble no more than three modules.

2. Using the assembled modules as a template, carefully mark the

center of all module-mounting holes on the panel.

3. Return the assembled modules to the clean work surface,

including any previously mounted modules.

4. Drill and tap the mounting holes for the recommended M4 or #8

screw.

5. Place the modules back on the panel, and check for proper hole

alignment.

…6 for any remaining modules.

Mount to a DIN Rail

The module can be mounted by using the following DIN rails:

• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)

• 35 x 15 mm (EN 50 022 - 35 x 15).

Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN-rail mounting area of the module against the DIN rail. The latches will momentarily open and lock into place.

The module can be replaced while the system is mounted to a panel (or DIN rail). Follow these steps in order.

1. Remove power.

ATTENTION

2. On the module to be removed, remove the upper and lower

mounting screws from the module or open the DIN latches by using a flat-blade or Phillips screwdriver.

3. Move the bus lever to the right to disconnect (unlock) the bus.

•sending an erroneous signal to your system’s field devices,

causing unintended machine motion.

•causing an explosion in a hazardous environment.

Electrical arcing causes excessive wear to contacts on both the module and its mating connector and may lead to premature failure.

4. On the right-side adjacent module, move its bus lever to the

right (unlock) to disconnect it from the module to be removed.

5. Gently slide the disconnected module forward.

If you feel excessive resistance, check that the module has been disconnected from the bus, and that both mounting screws have been removed or DIN latches opened.

Grounding the Module

TIP

6. Before installing the replacement module, be sure that the bus

lever on the module to be installed and on the right-side adjacent module are in the unlocked (fully right) position.

7. Slide the replacement module into the open slot.

8. Connect the modules together by locking (fully left) the bus

levers on the replacement module and the right-side adjacent module.

9. Replace the mounting screws or snap the module onto the DIN

rail.

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

It may be necessary to rock the module slightly from front to back to remove it, or, in a panel-mounted system, to loosen the screws of adjacent modules.

System Wiring Guidelines

Consider the following when wiring your system:

• All module commons (ANLG Com) are connected in the analog

module.

• The analog common (ANLG Com) is not connected to earth

ground inside the module.

• Channels are not isolated from each other.

• For optimum accuracy, limit overall cable impedance by

keeping your cable as short as possible. Locate the I/O system as close to your sensors or actuators as your application will permit.

• Use Belden 8761, or equivalent, shielded wire.

• Under normal conditions, the drain wire and shield junction

must be connected to earth ground via a panel or DIN rail mounting screw at the analog I/O module end.

(1)

Keep shield

connection to ground as short as possible.

• If multiple power supplies are used with analog inputs, the

power supply commons must be connected.

• The module does not provide loop power for analog inputs. Use

a Class 2 power supply that matches the input transmitter specifications.

• Differential analog inputs are more immune to noise than

single-ended analog inputs.

• Voltage outputs (Vout 0+ and Vout 1+) of the 1769-IF4FXOF2F

module are referenced to ANLG Com. Load resistance for a voltage output channel must be equal to or greater than 1 kΩ .

• Current outputs (Iout 0+ and Iout 1+) of the 1769-IF4FXOF2F

module source current that returns to ANLG Com. Load resistance for a current output channel must remain between 0 and 500 Ω .

• Voltages on Vin+, V/Iin-, and Iin+ terminals of the

1769-IF4FXOF2F module must be within ±10V DC of analog common (ANLG Com).

(1) In environments where high-frequency noise may be present, it may be necessary to directly ground cable

shields to earth at the module end and via a 0.1 µF capacitor at the sensor end.

ATTENTION

To prevent shock hazard, care should be taken when wiring the module to analog signal sources. Before wiring any analog module, disconnect power from the system power supply and from any other source to the analog module.

After the analog module is properly installed, follow the wiring procedure below. For proper operation and high immunity to electrical noise, always use Belden 8761 (shielded, twisted-pair) or equivalent wire.

ATTENTION

When wiring an analog input, take care to avoid connecting a voltage source to a channel configured for current input. Improper module operation or damage to the voltage source can occur.

Never connect a voltage or current source to an analog output channel.

4. At one end of the cable, twist the drain wire and foil shield

together.

Under normal conditions, this drain wire and shield junction must be connected to earth ground, via a panel or DIN rail mounting screw at the analog I/O module end. Keep the length of the drain wire as short as possible.

In environments where high frequency noise may be present, it may be necessary to also ground the cable shields to earth via a

0.1 µF capacitor at the sensor end.

5. At the other end of the cable, cut the drain wire and foil shield

back to the cable, unless the sensor end of the cable requires the shields to be connected to earth ground via the capacitor described in step 4

6. Connect the signal wires to the terminal block.

7. Connect the other end of the cable to the analog input or output

device.

When wiring analog inputs from current transmitters, you must place a jumper between the input channel’s Vin+ and Iin+ terminals or measurement accuracy of current input signals will be impacted.

TIP

Any analog input channel that is not wired to a voltage or current source should not be enabled in the module configuration file. Enabling unused analog inputs can result in non-zero values being displayed in the module input data file. Either disable all unused analog inputs or place a jumper wire between the Vin+ and V/Iin- terminals for those channels.

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, take preventative measures to make sure that connected equipment is not affected. Failure to take these preventative measures may result in unexpected load reactions.

Input Image

The input image file represents data words and status bits. Input words 0…3 hold the input data that represents the value of the analog inputs for channels 0…3. These data words are valid only when the channel is enabled and there are no errors. If time stamping is enabled, Word 4 in the input data file contains the time stamp value that corresponds to the module's last input-data sampling period. Input words 5 and 6 hold the general status bits for each input channel as well as the high and low alarm and over-range and under-range bits. To receive valid status information, the input channel must be enabled.

34 Publication 1769-UM019A-EN-P - October 2008

Module Data, Status, and Channel Configuration Chapter 3

Word 7 holds the general status bits for each output channel as well as the over and under output-clamp status bits. To receive valid status information, the output channel must be enabled. Words 8 and 9 contain the data echo values for the most recent data sent to the output channels.

Output Image

Output words 0 and 1 contain the digital data to be converted by outputs 0 and 1 into analog output signals. Word 2 contains the cancel latched-alarm control bits for the high and low alarms on each input channel. These bits are used to cancel alarms when alarms are latched. Word 3 contains the cancel latched output-clamp status control bits for the high and low output-clamp statuses on each output channel. These bits are used to cancel output-clamp statuses when the clamp statuses are latched.

Configuration File

The configuration file contains information that you use to define the way a specific channel functions.

The manipulation of bits from this file is normally done with programming software (for example, RSLogix 5000, RSLogix 500, or RSNetWorx for DeviceNet software) during initial configuration of the system. In that case, graphical screens provided by the programming software simplify configuration.

Some systems, like the 1769-ADN DeviceNet adapter system, also allow the bits to be altered as part of the control program by using communication rungs. In that case, it is necessary to understand the bit arrangement

TIP

Not all controllers support program access to the configuration file. Refer to your controller’s user manual.

Time Stamp Value (Word 4)

The module supports a 15-bit rolling time stamp that is updated during each new update of the analog input and output values. The time stamp has a 1 ms resolution. If the time stamp function is enabled, the time stamp value is placed in the Input Data file, word 16, following each module conversion cycle. Enable and/or disable this time stamp in word 1, bit 15 of the Configuration Data file.

General Input Status Bits (SI0…SI3)

Word 5, bits 0…3 contain the general operational status bits for input channels 0…3. If set (1), these bits indicate an alarm or range error associated with that channel. The over- and under-range bits and the high- and low-alarm bits for channels 0…3 are logically ORed to the appropriate general status bit.

Low Alarm Flag Bits (LI0 …LI3)

Word 6, bits 3, 7, 11, and 15 contain the low alarm flag bits for input channels 0…3. If set (1), these bits indicate the input signal is outside the user-defined range. The module continues to convert analog data to minimum full-range values. The bit is automatically reset (0) when the low alarm condition clears, unless the channel’s alarm bits are latched. If the channel’s alarm bits are latched, a set (1) low alarm flag bit clears via the corresponding Cancel Low Process Alarm Latch bit in your output data file.

High Alarm Flag Bits (HI0…HI3)

Word 6, bits 2, 6, 10, and 14 contain the high alarm flag bits for input channels 0…3. If set (1), the input signal is outside the user-defined range. The module continues to convert analog data to maximum full-range values. The bit is automatically reset (0) when the high alarm condition clears, unless the channel’s alarm bits are latched. If the channel’s alarm bits are latched, a set (1) high alarm flag bit clears via the corresponding Cancel High Process Alarm Latch bit in your output data file.

Over-range Flag Bits (OI0…OI3)

Over-range bits for channels 0…3 are contained in Word 6, bits 0, 4, 8, and 12. When set (1), this bit indicates an input signal is beyond the normal operating range. However, the module continues to convert analog data to the maximum full-range value. The bit is automatically reset (0) by the module when the over-range condition is cleared and the data value is within the normal operating range.

Under-range Flag Bits (UI0…UI13)

Under-range bits for channels 0…3 are contained in Word 6, bits 1, 5, 9, and 13. When set (1), this bit indicates an input signal is below the normal operating range. However, the module continues to convert analog data to the minimum full-range value. The bit is automatically reset (0) by the module when the under-range condition is cleared and the data value is within the normal operating range.

High clamp (over-range) bits for output channels 0 and 1 are contained in Word 7, bits 8 and 12. When set (1), these bits indicate an output value sent to the module is over the user-configured high clamp value for the output channel. The module clamps the analog output signal at the high clamp value. These bits are automatically reset (0) by the module when the high clamp condition clears, unless the channel’s clamp alarm bits are latched. If the channel’s clamp alarm bits are latched, a set (1) high clamp flag bit clears via the corresponding Cancel High Clamp Latch bit in your output data file.

Low Clamp (under-range) Flag Bits (UO0 and UO1)

Low clamp (under-range) bits for output channels 0 and 1 are contained in Word 7, bits 9 and 13. When set, these bits indicate an output value sent to the module is under the user-configured low clamp value for the output channel. The module clamps the analog output signal at the low clamp value. These bits are automatically reset (0) by the module when the low clamp condition clears, unless the channel’s clamp alarm bits are latched. If the channel’s clamp alarm bits are latched, a set (1) low clamp flag bit clears via the corresponding Cancel Low Clamp Latch bit in your output data file.

The output data table lets you write analog output data and unlatch command data to the module with the control program and bit access. The data table structure is shown in the table below. For each module, slot x, words 0 and 1 in the output data file contain the digital values of the data to be converted to analog signals by the module outputs. The most significant bit (MSB) is the sign bit, in two’s complement format. ‘Nu’ indicates not used with the bit set to zero.

Cancel Input Alarm Control Bits (CLL0…CLL3 and CLH0…CLH3)

These bits are written during Run mode to cancel any latched lowand high-process alarms. The alarm is unlatched when the unlatch bit is set (1) and the alarm condition no longer exists. If the alarm condition persists, then the unlatch bit has no effect until the alarm condition no longer exists. You need to keep the unlatch bit set until verification from the appropriate input-channel status word that the alarm status bit has cleared (0). Then you need to reset (0) the unlatch bit. The module will not latch an alarm condition if a transition from ‘no alarm’ to ‘alarm’ occurs while a channel’s cancel latch bit is set.

Cancel Output Clamp Flag Control Bits (CLO0…CLO1 and CHO0…CHO1)

These bits are written during Run mode to cancel any latched low and high clamp status bits. The status bit is unlatched when the unlatch bit is set (1) and the clamp condition no longer exists. If the clamp condition persists, then the unlatch bit has no effect until the clamp condition no longer exists. You need to keep the unlatch bit set until verification from the appropriate output-channel status word that the clamp status bit has cleared (0). Then, you need to reset (0) the unlatch bit. The module will not latch a clamp status bit if a transition from no alarm to alarm occurs while a channel’s cancel latch bit is set.

Module Data, Status, and Channel Configuration Chapter 3

Enable/Disable Channel (EC)

This configuration selection lets each channel be enabled individually.

TIP

When a channel is not enabled (EC = 0), no voltage or current reading is provided to the controller by the A/D converter.

Any analog input channel that is not wired to a voltage or current source should not be enabled in the module configuration file. Enabling unused analog inputs can result in non-zero values being displayed in the module input-data file. Either disable all unused analog inputs or place a jumper wire between the Vin+ and V/Iin- terminals for those channels.

Input Filter Selection

The input filter selection field lets you select the filter frequency for each channel. The filter frequency affects the noise rejection characteristics, channel step response, and module update time, as explained below.

Noise Rejection

The module uses firmware that provides noise rejection for the input signals. The filter is programmable, allowing you to select from nine filter frequencies for each channel. A lower frequency (60 Hz versus 1000 Hz) can provide better noise rejection but it increases channel step-response time.

Normal Mode Rejection is better than 50 dB at 50 and 60 Hz, with the 50 and 60 Hz filters selected, respectively. Transducer power-supply noise, transducer circuit noise, or process variable irregularities may also be sources of normal mode noise.

Common Mode Rejection is better than 70 dB at 50 and 60 Hz, with the 50 and 60 Hz filters selected, respectively. The modules perform well in the presence of common mode noise as long as the signals applied to the IN+ and ANLG Com input terminals do not exceed the working voltage rating of the module. Improper earth ground may be a source of common mode noise.

Publication 1769-UM019A-EN-P - October 2008 43

Chapter 3 Module Data, Status, and Channel Configuration

Channel Step Response

The selected channel filter frequency determines the channel’s step response. The step response is the time required for the analog input signal to reach 100% of its expected final value. This means that if an input signal changes faster than the channel step response, a portion of that signal will be attenuated by the channel filter.

Filter Selection Channel Step Response

5 Hz 802 ms 10 Hz 401 ms 50 Hz 81 ms 60 Hz 65 ms 100 Hz 42 ms 250 Hz 17 ms 500 Hz 10 ms 1000 Hz 5 ms

Module-update Time and Scanning Process

The module update time is defined as the time required for the module to sample and convert the input signals of all enabled input channels and provide the resulting data values to the Data Input file. In addition, if any output channels are enabled, a constant amount of time must be added to the variable input update times to arrive at the total module-update time. Module-update time can be calculated by adding the sum of all enabled channel-update times. Channel update times include channel scan time, channel switching time, and converter configuration time. The module sequentially samples the channels in a continuous loop, and then requires a constant amount of time to write to any enabled output channels.

Module update time is calculated by adding up all of the input channel update times and then adding a constant time if any of the output channels are enabled. Each enabled input channel has one of two channel-update times assigned. If No Filter is selected as the filter setting for an input channel, its channel update time is 100 µs. If any other filter setting is selected for an input channel, then its channel update time is 200 µs. If one or both output channels are enabled, an additional 100 µs must be added to the input-channel update time total to arrive at the total module update time. The 100 µs added for output channels being enabled is constant whether one or both output channels are enabled.

Module Data, Status, and Channel Configuration Chapter 3

Input Type/Range Selection

This selection lets you configure each input channel individually and provides the ability to read the configured range selections.

Input Data Selection Formats

This selection configures each input channel to present analog data in any of the following formats:

• Raw/Proportional Data

• Engineering Units

• Scaled-for-PID

• Percent Range

See Valid Input Data

on page 46.

Raw/Proportional Data

The value presented to the controller is proportional to the selected input and scaled into the maximum data range allowed by the bit resolution of the A/D converter. For example, the data value range for a ±10V DC user input is -32,766…32,766, which covers the full-scale range of -10.5…10.5V.

Engineering Units

The module scales the analog input data to the actual current or voltage values for the selected input range. The resolution of the engineering units is 0.001V or 0.001 mA per count.

Scaled-for-PID

The value presented to the controller is a signed integer with 0 representing the lower limit of the normal operating range and 16,383 representing the upper limit of the normal operating range. Allen-Bradley controllers, such as the MicroLogix 1500 controller, use this range in their PID equations. The amount over and under the normal operating range (the full-scale range) is also supported.

Publication 1769-UM019A-EN-P - October 2008 45

Chapter 3 Module Data, Status, and Channel Configuration

Percent Range

The input data is presented as a percentage of the normal operating range. For example, 0…10V DC equals 0…100%. The amount over and under the normal operating range (the full-scale range) is also supported.

Real Time Sampling

This parameter instructs the module how often to initiate a conversion cycle that will convert each enabled input channel and then place that data into the Input Data file. A conversion cycle is defined as the sequential conversion of each input that is enabled. When the module has performed a conversion on each of the enabled inputs, it is ready to begin the next conversion cycle. This feature is applied on a module-wide basis.

During module configuration, you specify a Real Time Sampling (RTS) period by entering a value into Word 0 of the Configuration Data file. This value entered in Word 0 can be in the range of 0…5000 and indicates the conversion cycle rate the module will use in 1 ms increments.

46 Publication 1769-UM019A-EN-P - October 2008

Module Data, Status, and Channel Configuration Chapter 3

If you enter a zero for the Real Time Sample Rate, the module initiates conversion cycles at the fastest rate possible, controlled by the filter setting selected for each enabled channel. Once all of the channels’ input data have been converted, the Input Data file is updated for all enabled channels at the same time.

If you enter a non-zero value for the Real Time Sample Rate, the module compares the Real Time Sample Rate value with the minimum and maximum values allowed by the module. If the value entered for the Real Time Sample Rate is less than 0 or greater than 5000 decimal, the module indicates a configuration error. The longest Real Time Sample Rate supported by the modules is 5 seconds, which corresponds to the maximum value for Word 0 of the Configuration Data file of 5000 decimal.

Time Stamping

This parameter instructs the module to insert a time stamp value into the Input Data file every time the file is updated.

During module configuration, you enable time stamping by using Word 1, bit 15 of the Configuration Data file: Enable Time Stamping (ETS). Setting the ETS bit (ETS = 1) enables the module’s time stamping function. Clearing the ETS bit (ETS = 0) disables the function. The default condition of the ETS bit is disabled (ETS = 0).

When time stamping is enabled, the module provides a rolling time stamp value of 0…32,767 with each count representing 1 ms. When the time stamp count reaches 32,767, the value is reset to 0 and continues to increment 1 count every millisecond.

When enabled, the Input Data file is updated with the latest time stamp value that corresponds to the end of each module conversion cycle. Sequentially, each enabled input is converted once per conversion cycle. When Real Time Sampling is not enabled, conversion cycles are repeatedly initiated at the module update rate. If Real Time Sampling is used, the conversion cycles are initiated at a rate equal to the real-time sampling rate. The time stamp value is updated at the end of every conversion cycle.

Chapter 3 Module Data, Status, and Channel Configuration

Process Alarms

Process alarms alert you when the module has exceeded configured high or low limits for each input channel. You can latch process

alarms. Process alarms can generate interrupts. alarms are set at two user-configurable alarm trigger points.

• Process Alarm High

• Process Alarm Low

The operation of each input channel’s process alarms are controlled by bits in the Configuration Data file. Enable alarms for a channel by setting (EA = 1) the EA bit for that channel. Set the AL bit (AL = 1) for a channel to enable alarm latching. Set the EI bit (EI = 1) for a channel

to enable interrupts on that channel’s process alarms.

Each channel’s process alarm-high data value and process alarm-low data value are set by entering values in the corresponding words of the Configuration Data file for that channel.

(1)

A channel’s process

(1)

The values entered for a channel’s process alarms must be within the full-scale data range as set by the Input Data Format selected for that channel. If the process alarm data value entered is outside the full-scale data range set for a channel, the module indicates a configuration error.

Alarm Deadband

You may configure an alarm deadband to work with the process alarms. The deadband lets the process alarm status bit remain set, despite the alarm condition disappearing, as long as the input data remains within the deadband of the process alarm.

This illustration shows an example of input data that sets each of the two alarms at some point during module operation. In this example, latching is disabled; therefore, each alarm turns OFF when the condition that caused it to set ceases to exist and the input data clears the alarm deadband regions.

(1) Module interrupts are not supported by all bus masters. Refer to your controller’s user manual to determine

whether it can support module interrupts.

Output Channel

Each output channel is independently configured via a group of eight consecutive words in the Configuration Data file. The first two words

Enable/Disable Channel (EC)

This configuration lets each channel be enabled individually. When a channel is not enabled (EC = 0), the output channel is set to 0V or 0mA.

Program Mode (PM)

This configuration selection provides individual Program mode selection for the output channels. When this selection is disabled (PM = 0), the module holds the last state. This means that the output remains at the last converted value prior to the condition that caused the control system to enter Program mode.

IMPORTANT

If this selection is enabled (PM = 1), and the system enters the Program mode, the module converts the user-specified value from the channel’s Program Mode word to the appropriate analog output for the range selected.

Hold last state is the default condition for the module during a control system Run-to-Program mode change.

TIP

50 Publication 1769-UM019A-EN-P - October 2008

Not all controllers support alternate output states and this function. Refer to your controller’s user manual for details.

Module Data, Status, and Channel Configuration Chapter 3

Program Value

Use each output channel’s program value word to set the analog values for the outputs to assume when the system enters the Program mode. Valid values are dependent upon the type/range and data format selected for each output channel or the user-defined output clamp values. If the value you enter is outside the full range for the output type/range and data format selected, or outside the limits set by the channel’s low and high clamp values, the module generates a configuration error. The default value is 0.

TIP

Not all controllers support alternate output states and this function. Refer to your controller’s user manual for details.

Fault Mode (FM)

This configuration selection provides individual Fault mode selection for the output channels. When this selection is disabled (FM = 0), the module holds the last state, meaning that the output remains at the last converted value prior to the condition that caused the control system to enter the Fault mode.

IMPORTANT

If this selection is enabled (FM = 1), and the system enters the Fault mode, the module converts the user-specified value from the channel’s Fault Mode word to the appropriate analog output for the range selected.

TIP

Hold last state is the default condition for the module during a control system Run-to-Fault mode change.

Chapter 3 Module Data, Status, and Channel Configuration

Fault Value

Use each output channel’s fault value word to set the analog values for the outputs to assume when the system enters the Fault mode. Valid values depend upon the type/range and data format selected for each output channel or the user-defined output clamp values. If the value you enter is outside of the full range for the output type/range and data format selected, or outside of the limits set by the channel’s low and high clamp values, the module generates a configuration error. The default value is 0.

TIP

Not all controllers support alternate output states and this function. Refer to your controller’s user manual for details.

Program to Fault Enable (PFE)

If a system currently in Program mode faults, this setting determines whether the program or fault value is applied to the output. If the selection is enabled (PFE = 1), the module applies the Fault mode data value. If the selection is disabled (PFE = 0), the module applies the Program mode data value. The default setting is disabled.

TIP

Not all controllers support alternate output states and this function. Refer to your controller’s user manual for details.

Clamping (Limiting)

Clamping limits the outputs from the module to within a user-configured range when the controller commands an output to a value outside of that range. The module supports a high clamp value and a low clamp value for each output channel. Once clamps are set for a module, any data received from the controller that exceeds those clamp values sets an appropriate clamp status bit and transitions the output to that limit but not beyond.

52 Publication 1769-UM019A-EN-P - October 2008

Module Data, Status, and Channel Configuration Chapter 3

Clamp High and Clamp Low Data Values

Clamping is disabled on a per channel basis for each output channel by entering a 0 value in both the clamp high data value and clamp low data value words in the configuration-data file. If either the clamp high data value or clamp low data value words have a non-zero value entered, clamping is enabled for the corresponding output channel. Non-zero clamp data values are considered valid only if they are within the full-range limits set by the type/range and data format selections for the channel. Also, the clamp data values are valid only if the high clamp data value for an output channel is greater than or equal to the low clamp data value.

Latch Clamp Status (LC)

If the selection is enabled (LC = 1), the module latches any clamp status bits that are set in the Input Data file. Latched clamp status bits must be reset via the Output Data file. If the selection is disabled (LC = 0), any clamp status bits that are set in the Input Data file are automatically reset when the clamp limits are no longer exceeded by the controller. The default setting is disabled.

Enable Low Clamp Alarm Interrupt and Enable High Clamp Alarm Interrupt (ELI and EHI)

If the selection is enabled (ELI = 1 or EHI = 1), the module generates a module interrupt to the controller. A separate interrupt can be enabled for each output channel’s high clamp status and low clamp status. If the selection is disabled (ELI = 0 or EHI = 0), no module interrupts are generated when output clamp status bits are set. The default setting is disabled.

TIP

Not all controllers support alternate output states and this function. Refer to your controller’s user manual for details.

Output Ramping

Ramping limits the speed at which an output signal can change. This prevents vast transitions in the output from damaging the output controls.

Ramp to Fault mode is the only type of ramping supported by the module. This type of ramping occurs when the present output value changes to the fault value after a change in the controller's status to Fault mode has occurred.

Publication 1769-UM019A-EN-P - October 2008 53

Chapter 3 Module Data, Status, and Channel Configuration

Enable Ramping (ER)

If the selection is enabled (ER = 1), the module controls the ramp rate of the output when the system transitions from Run to Fault mode based on the value entered in the channel’s ramp-rate configuration word. If the selection is disabled (ER = 0), no ramping control of the output is provided. The default setting is disabled.

TIP

Not all controllers support alternate output states and this function. Refer to your controller’s user manual for details.

Ramp Rate

The ramp rate is defined in terms of the selected range/format in units per second. For example, in the 0…20 mA range and percent full scale format, a ramp rate of 1050 is 10% per second (2 mA/s), since 1050 is 10% of the total number of counts in the full scale of the 0…20 mA range when using percent full scale format.

This table describes how the ramp rate is determined for all output types/ranges and output data formats.

If configured, ramping takes place only when the output is commanded to go to a fault state. Ramping does not occur during normal run operation.

The ramp rate values are entered in the Configuration Data file and are accepted as valid only if:

• the number of counts entered for a channel’s ramp rate is

greater than or equal to a minimum of 1% of the total number of full scale counts for the channel’s selected data format.

• the number of counts entered for a channel’s ramp rate is equal

to zero and ramping is not enabled for that channel.

TIP

Not all controllers support alternate output states and this function. Refer to your controller’s user manual for details.

Output Type/Range Selection

This selection lets you configure each output channel individually and provides the means of designating whether the output is a voltage or current source. The output range for each output channel is also configured by this selection.

Publication 1769-UM019A-EN-P - October 2008 55

Chapter 3 Module Data, Status, and Channel Configuration

Output Data Selection Formats

This selection configures each output channel to accept digital data in any of the following formats:

• Raw/Proportional Data

• Engineering Units

• Scaled-for-PID

• Percent Range

See Valid Output Data

on page 57.

Raw/Proportional Data

The value sent by the controller to the output channel is proportional to the selected output and scaled into the maximum data range allowed by the bit resolution of the D/A converter. For example, the data value range for a ±10V DC user input is -32,764…32,764, which covers the full-scale range of -10.5…10.5V.

Engineering Units

The value sent by the controller to the output channel is the actual current or voltage value for the selected output range. The resolution of the engineering units is 0.001V or 0.001 mA per count.

Scaled-for-PID

The value sent by the controller to the output channel is a signed integer with 0 representing the lower limit of the normal operating range and 16,380 representing the upper limit of the normal operating range. Allen-Bradley controllers, such as the MicroLogix 1500 controller, use this range in their PID equations. The amount over and under the normal operating range (the full-scale range) is also supported.

Percent Range

The value sent by the controller to the output channel is presented as a percentage of the normal operating range selected for that output channel. For example, 0…10V DC equals 0…100%. The resolution of the percent range is 0.01% per count. The amount over and under the normal operating range (the full-scale range) is also supported.

Safety Considerations

Safety considerations are an important element of proper troubleshooting procedures. Actively thinking about the safety of yourself and others, as well as the condition of your equipment, is of primary importance.

The following sections describe several safety concerns you should be aware of when troubleshooting your control system.

ATTENTION

Never reach into a machine to actuate a switch because unexpected motion can occur and cause injury.

Remove all electrical power at the main power-disconnect switches before checking electrical connections or inputs/outputs causing machine motion.

Power Status Indicator

When the green status indicator on the analog module is illuminated, it indicates that power is applied to the module.

Activate Devices When Troubleshooting

When troubleshooting, never reach into the machine to actuate a device. Unexpected machine motion could occur.

59Publication 1769-UM019A-EN-P - October 2008 59

Chapter 4 Module Diagnostics and Troubleshooting

Stand Clear of the Machine

When troubleshooting any system problem, have all personnel remain clear of the machine. The problem could be intermittent, and sudden unexpected machine motion could occur. Have someone ready to operate an emergency stop switch in case it becomes necessary to shut off power to the machine.

Program Alteration

There are several possible causes of alteration to the user program, including extreme environmental conditions, electromagnetic interference (EMI), improper grounding, improper wiring connections, and unauthorized tampering. If you suspect a program has been altered, check it against a previously saved program on an EEPROM or UVPROM memory module.

Power Cycle Diagnostics

Safety Circuits

Circuits installed on the machine for safety reasons, like over-travel limit switches, stop push buttons, and interlocks, should always be hard-wired 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.

When you cycle power to the module, a series of internal diagnostic tests are performed. These diagnostic tests must be successfully completed or the module status indicator remains off and a module error results and is reported to the controller.

Module Status Indicator

On Proper Operation No action required. Off Module Fault Cycle power. If condition persists, replace the

module. Call your local distributor or Rockwell Automation for assistance.

Module Diagnostics and Troubleshooting Chapter 4

Channel Diagnostics

When any channel is enabled, the module performs a diagnostic check to see that the channel has been properly configured. In addition, the module checks each channel during every conversion cycle for input channel over-range and under-range, input channel high and low process alarm conditions, and output channel high and low clamp conditions.

Out-of-range Detection

Whenever data received at an input is out of the defined normal operating range, an over-range or under-range error is indicated in the Input Data file.

Process Alarm Detection

Whenever data received at an input meets or exceeds that channel’s configured process alarm limits, a high alarm or low alarm error is indicated at the Input Data file.

Non-critical Versus Critical Module Errors

Output Clamp Detection

Whenever data is sent to an output that meets or exceeds that channel’s configured clamp limits, a low or high clamp error is indicated in the Input Data file.

Non-critical module errors are typically recoverable. Channel errors (over-range or under-range errors, process alarms, and open circuit errors) are non-critical. Non-critical errors are indicated in the module input data table.

Critical module errors are conditions that prevent normal or recoverable operation of the system. When these types of errors occur, the system typically leaves the run or program mode of operation until the error can be dealt with.

Critical module errors are indicated in Error Codes

on page 63.

Error Description

During system configuration, if you set the fields in the configuration file to invalid or unsupported values, the module generates a configuration error and the system controller enters a Fault condition. The invalid configuration data must be corrected and the program downloaded again for the system to enter Run mode. You cannot change module configuration data while the system is in Run mode. Any changes are ignored by the module, which continues to operate with its previous configuration.

This appendix examines the modules’ addressing scheme and describes module configuration using RSLogix 500 software and a MicroLogix 1500 controller.

Module Input Image

The module’s input image file represents data words and status bits. Input words 0…3 hold the input data that represents the value of the analog inputs for channels 0…3. These data words are valid only when the channel is enabled and there are no errors. Input words 5…7 hold the status bits. To receive valid status information, the channel must be enabled.

For example, to obtain the general input status of channel 2 of the analog module located in slot 3, use address I:3.5/2.

Module Output Image

The module’s output image file represents data words and unlatch control bits. Output words 0…1 are written with output data that represents the analog value commanded to the module’s output channels 0…1. These data words only represent the state of the module’s outputs when the channel is enabled and there are no errors. Output words 2…3 are written to control the unlatching of input process alarms or output clamp status bits.

For example, to control the unlatching of a latched output clamp status bit of output channel 1 of the module located in slot 3, use address O:3.3/1.

Appendix

Two’s Complement Binary Numbers

The controller memory stores 16-bit binary numbers. Two’s complement binary is used when performing mathematical calculations internal to the controller. Analog input values from the analog modules are returned to the controller in 16-bit two’s complement binary format. For positive numbers, the binary notation and two’s complement binary notation are identical.

As indicated in the figure on the next page, each position in the number has a decimal value, beginning at the right with 2 at the left with 2

. Each position can be 0 or 1 in the controller memory. A 0 indicates a value of 0; a 1 indicates the decimal value of the position. The equivalent decimal value of the binary number is the sum of the position values.

Positive Decimal Values

The far left position is always 0 for positive values. This limits the maximum positive decimal value to 32,767 (all positions are 1 except the far left position).

Glossary

The following terms and abbreviations are used throughout this manual. For definitions of terms not listed here refer to the Allen-Bradley Industrial Automation Glossary, publication AG-7.1

A/D converter– Refers to the analog to digital converter inherent to the module. The converter produces a digital value whose magnitude is proportional to the magnitude of an analog input signal.

alternate last state – A configuration selection that instructs the module to convert a user-specified value from the channel fault or program/idle word to the output value when the module enters the Fault or Program mode.

analog input module – A module that contains circuits that convert analog voltage or current input signals to digital values that can be manipulated by the controller.

attenuation – The reduction in the magnitude of a signal as it passes through a system.

bus connector – A 16-pin male and female connector that provides electrical interconnection between the modules.

channel – Refers to analog input or output interfaces available on the module’s terminal block. Each channel is configured for connection to a variable voltage or current input or output device, and has its own data and diagnostic status words.

channel update time – The time required for the module to sample and convert the input signals of one enabled input channel and update the channel data word.

common mode rejection – For analog inputs, the maximum level to which a common mode input voltage appears in the numerical value read by the controller, expressed in dB.

common mode rejection ratio – The ratio of a device’s differential voltage gain to common mode voltage gain. Expressed in dB, CMRR is a comparative measure of a device’s ability to reject interference caused by a voltage common to its input terminals relative to ground. CMRR=20 Log

common mode voltage – For analog inputs, the voltage difference between the negative terminal and analog common during normal differential operation.

10 (V1/V2)

common mode voltage range – For analog inputs, the largest voltage difference allowed between either the positive or negative terminal and analog common during normal differential operation.

Publication 1769-UM019A-EN-P - October 2008 85

Glossary

configuration word – Contains the channel configuration information needed by the module to configure and operate each channel.

D/A Converter – Refers to the digital-to-analog converter inherent to the module. The converter produces an analog DC voltage or current signal whose instantaneous magnitude is proportional to the magnitude of a digital value.

dB – (decibel) A logarithmic measure of the ratio of two signal levels.

data echo – The digital value currently being converted by the D/A

converter and shown in words 8 and 9 of the module’s input data file. Under normal operating conditions, the data echo value is the same value that is being sent from the bus master to the output module.

data word – A 16-bit integer that represents the value of the analog input or output channel. The channel data word is valid only when the channel is enabled and there are no channel errors. When the channel is disabled the channel data word is cleared (0).

differential operation – The difference in voltage between a channel’s positive terminal and negative terminal.

digital filter – A low-pass filter incorporated into the A/D converter. The digital filter provides very steep roll-off above it’s cut-off frequency, which provides high frequency noise rejection.

filter – A device that passes a signal or range of signals and eliminates all others.

filter frequency – (-3 dB frequency) The user-selectable frequency.

full scale – The magnitude of voltage or current over which normal

operation is permitted.

full scale error – (gain error) The difference in slope between the actual and ideal analog transfer functions.

full scale range – (FSR) The difference between the maximum and minimum specified analog input values.

hold last state – A configuration selection that instructs the module to keep the outputs at the last converted value prior to the condition that caused the control system to enter the Fault or Program mode.

input image – The input from the module to the controller. The input image contains the module data words and status bits.

86 Publication 1769-UM019A-EN-P - October 2008

Glossary

LSB – (Least Significant Bit) The bit that represents the smallest value within a string of bits. For analog modules, 16-bit, two’s complement binary codes are used in the I/O image in the card.

For analog inputs, the LSB is defined as the rightmost bit, bit 0, of the 16-bit field. For analog outputs, the three rightmost bits are not significant, and the LSB is defined as the third bit from the right, bit 2, of the 16-bit field.

linearity error – An analog input or output is composed of a series of voltage or current values corresponding to digital codes. For an ideal analog input or output, the values lie in a straight line spaced by a voltage or current corresponding to 1 LSB. Any deviation of the converted input or actual output from this line is the linearity error of the input or output. The linearity is expressed in percent of full scale input or output. See the variation from the straight line due to linearity error (exaggerated) in the example below.

Actual Transfer Function

Ideal Transfer

number of significant bits – The power of two that represents the total number of completely different digital codes an analog signal can be converted into or generated from.

module scan time – same as module update time

module update time – For inputs, the time required for the module

to sample and convert the input signals of all enabled input channels and make the resulting data values available to the controller. If output channels are enabled, a constant amount of time must be added to the input update time to arrive at the total module update time.

multiplexer – A switching system that allows several signals to share a common A/D or D/A converter.

normal mode rejection – (differential mode rejection) A logarithmic measure, in dB, of a device’s ability to reject noise signals between or among circuit signal conductors.

normal operating range – Input or output signals are within the configured range.

Publication 1769-UM019A-EN-P - October 2008 87

Glossary

overall accuracy – The worst-case deviation of the output voltage or current from the ideal over the full output range is the overall accuracy. For inputs, the worst-case deviation of the digital representation of the input signal from the ideal over the full input range is the overall accuracy. This is expressed in percent of full scale.

Gain error, offset error, and linearity error all contribute to input and output channel accuracy.

output accuracy – The difference between the actual analog output value and what is expected, when a given digital code is applied to the d/a converter. Expressed as a ± percent of full scale. The error will include gain, offset and drift elements, and is defined at 25 °C (77 °F), and also over the full operating temperature range, 0…60 °C (0…140 °F).

output image – The output from the controller to the module outputs. The output image contains the digital output data to be converted to analog output signals by the module.

repeatability – The closeness of agreement among repeated measurements of the same variable under the same conditions.

resolution – The smallest detectable change in a measurement, typically expressed in engineering units (for example, 1 mV) or as a number of bits. For example a 12-bit system has 4096 possible output states. It can therefore measure 1 part in 4096.

status word – Contains status information about the channel’s current configuration and operational state. You can use this information in your ladder program to determine whether the channel data word is valid.

step response time – For inputs, this is the time required for the channel data word signal to reach a specified percentage of its expected final value, given a large step change in the input signal.

update time – See module update time
