Preface 2

Definitions

The following define the intended operation of the Encoder/Counter module.

Term Definition

Lead Breakage Typically requires a shunt resistor (across the load) to detect

3 levels of current/input states -

• Open (Wire Off, Device = ?)

• Off (Wire OK, Device Off)

• On (Wire OK, Device On)

This method does not check the input against a time base, only that the device wiring (current loop) is intact

Missing Pulse Typically uses an input pulse to reset a watc hdog timer (fixed

or programmable HW). This method does detect “Lead Breakage”, since a broken wire will time-out the watchdog.

Zero Frequency Typically uses an input pulse to calculate an input frequency

and verify it is above an error threshold. This method does detect Lead Breakage, since a broken wire will generate a 0Hz frequency.

Missing Pulse or Zero Frequency will also detect a customer device stuck high or low, since the counter is monitoring for a change in the input state. Currently, the Counter/Encoder Modes do not have Zero Frequency Detection - the A & B inputs are time independent, only looking for input edge changes to increment/decrement the count value.

The Period/Rate and Continuous Rate modes do have Zero Frequency Detection, since the Z input is monitored for Zero Frequency in Firmware (A and B inputs are not used and not monitored).

The Rate Measurement mode inherently has Zero Frequency Detection, since no A pulses in any sample period are = 0Hz (B and Z inputs are not used and not monitored).

What This Chapter Contains

Module Description and Features

Read this chapter to learn about types, features, and capabilities of encoder/counter modules.

Encoder/counter modules install into the Point I/O terminal base (1734-TB or 1734-TBS) and interface with the Point I/O DeviceNet Pass-through (1734-PDN) or the Point I/O DeviceNet Adapter (1734-ADN).

An encoder/counter module serves as a signal conditioner, function block, and counter between the customer process signals on the terminal base and the POINTBus containing the command information. The main functional blocks are the the following.

• Customer digital I/O interface

• Counter ASIC

• Microprocessor

The encoder/counter module accepts feedback from the following.

• Encoders (either single-ended or differential)

• Pulse generators

• Mechanical limit switches

• Frequencies up to 1 MHz

A filter is available with the following settings.

• 50 Hz

• 500 Hz

• 5 kHz

• 50 kHz

Turn the filter off to achieve the fastest counting rate.

The input voltage range is 5V dc (1734-IJ) or 15-24V dc (1734-IK). The module returns the count or frequency in the form of a 24 bit binary number (0 - 16,777,215) expressed in a 32 bit long word.

Each counter has a user-selectable preset and rollover value associated with it.

1-2 About the Modules

Operating Modes

The encoder/counter modules operate in the modes shown in the table.

Mode Description

Counter Mode Read incoming single phase pulses, return a binary

count

Encoder Mode Read incoming 2 phase quadrature pulses, return a

binary count

Period/Rate Mode Count internal clocks during the On period, return a

frequency

Rate Measurement Mode Read pulses during the sample period, return a

frequency

The operation of the counter and encoder modes is nearly identical. The difference between the two modes is in the type of feedback (1 phase versus 2 phase) for the count direction (up or down).

• In encoder mode, a transition is expected on B for counting to proceed in a direction.

• In counter mode, the B input may be left at a static level.

Select operating modes by writing appropriate configuration data to the module.

Counter Mode

The counter mode reads incoming pulses and returns a binary nu mber (0 - 16,777,215

single phase inputs. The module determines the Phase B input state, and counts up or down accordingly.

Channel A input is used as the counting pulse while chan nel B is used to determine the direction.

[B = High, Count = Down; B = Low or floating (not connected), Count = Up]

The Channel B input may be tied high or low for unidirectional counting, or toggled for bidirectional counting.

The two basic encoder types are absolute and incremental. A single output incremental encoder is called a tachometer encoder. A dual channel incremental encoder with one channel leading the other by 90° is called a quadrature encoder.

A system using a quadrature encoder may include an optional zero pulse, or index, serving as a reference mark for system reset. The principal disadvantage of a system using incremental en coders is that a power interruption causes the loss of position reference, so a system must be reinitialized or returned to a known zero position.

Absolute encoders typically have higher speed requi rements (200 KHz typical) for motion control applications. An absolute encoder has a unique code associated with each position, so the exact position is always known, even if the system power is turned off.

Period / Rate Mode

The Period/Rate Mode will return an incoming frequency and a total accumulated count to the POINTBus, by g internal clock with an external signal.

This mode determines the frequency and total number of input pulses by counting the number of internal 5MHz clock pulses over a user-specified number of input signal pulses. At the end of the specified number of pulses, the module returns the frequency (0 - 1 MHz).

Updated Here

As the frequency of the incoming pulse train at the Z (Gate/Reset) terminal increases, the number of sampled pulses from the 5 MHz clock decreases. Since accuracy is related to the number of pulses received over the sample period, the accuracy decreases with increasing frequencies at the Gate/Reset terminal. Refer to the following Scaling table.

Sample Pulses for 1/2 Cycle of Z Gate/Reset Pulse

Scaling the input frequency through the use of a scalar can lessen the decrease in accuracy. A scalar value of 1 returns an accurate input frequency only if incoming input pulses have a 50% duty cycle.

Operation of Scalar

In the Period/Rate mode, the scalar lets the incoming pulse train at the Z Gate/Reset pin be divided by a user-defined number. There is one scalar value for each counter. Acceptable values for the scalar are 1, 2, 4, 8, 16, 32, 64, and 128. The default value for each scalar is 1. Note that a “0” scalar is equivalent to a “1”.

The product of the Sample Period times the scalar should be less than

6.71 seconds in order to avoid a zero frequency detect indication.

(5 MHz sample time = 200ns; 16,777,216 counts x 200ns x 2 half cycles of Z = 6.71 seconds)

Publication 1734-UM006B-EN-P - August 2005

About the Modules 1-7

Rate Measurement Mode

The Rate Measurement mode determines the frequency and total number of input pulses over a user-specified sample period. At the end of the interval, the module returns a value representing the sampled number of pulses and a value indicating the incoming frequency.

When the count and frequency update, any associated outputs are checked against their associated presets. Frequency is calculated by dividing the accumulated count by the user selected time period, and is returned in the read data. Allowable time periods are 10ms to 3s in 10ms increments, with a default value of 1s. Note that a “0” time period is equivalent to the 1s default.

New Data Indicator

A two-bit counter, C1 & C0, updates every time an "event" occurs, indicating that new data is available in the Stored/Accumulated Count words. Definitions for events are as follows.

• Any active gate transition in any of the Store Count (Counter or Encoder) modes

• The end of the gate sample period in either the Period mode or Rate mode

• The end of the programmed sample period in the Rate Measurement mode.

To use these bits reliably, acquisition of data from the Counter Module must occur faster than the events, which cause C1/C0 to increment. When C1/C0 is updated, a Change Of State (COS) message can be sent.

Default Configuration

The module's default configuration on startup is as follows.

• Counter Mode

• 50Hz filter on A, B and Z

• No time base

• Rollover = 0x00FFFFFF

• Preset = 0

• No scalar

• Counter Control Safe State = 0

To modify the default settings to those required for your application, refer to the Input and Output section of this manual.

Install the Mounting Base and Wiring Base Assembly

The wiring base assembly (1734-TB or 1734-TBS) consists of a mounting base (cat. no. 1734-MB) and a removable terminal block (catalog number 1734-RTB or 1734-RTBS).

You can install the assembly, or just the mounting base. T o install the mounting base and wiring base assembly on the DIN rail, proceed as follows.

ATTENTIO

POINT I/O is grounded through the DIN rail to chassis ground. Use zinc-plated, yellow-chromated steel DIN rail to assure proper grounding. The use of DIN rail materials (such as aluminum and plastic) that can corrode, oxidize, or are poor conductors can result in improper or intermittent grounding.

Secure DIN rail to mounting surface approximately every 200 mm (7.8 inches).

1. Position the mounting base and wiring base assembly vertically above the installed units (adapter, power supply or existing module).

2. Slide the mounting base down so that the interlocking side pieces engage the adjacent module or adapter.

Install the Module

Install the module before or after base installation. Ma ke sure that you correctly key the mounting base before installin g the module into the mounting base. In addition, make sure you position the mounting base locking screw horizontal, as referenced to the base.

WARNING

When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.

1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise until the number required for the type of module you are installing aligns with the notch in the base.

Communicate with Your Module

POINT I/O modules send (consume) and receive (produce) I/O messages. You map these messages into the processor’s memory.

This module produces 6 or 10 bytes of input data (scanner Rx) (status). It consumes 1 byte of I/O data (scanner Tx). Use parameters 11 and 12 to select assembly 101, 102, or 103 for data produced by the module.

When you send a configuration to the module, you check it for consistency before applying it. Monitor the PE bit with your user program to isolate any problems with an improper ly configured module. If the configuration is acceptable, the counter ASIC is disabled while the ASIC is loaded with new operational parameters. Outputs can turn off during this reconfiguration .

3-2 Input and Output Data

Detailed Description of Data Table Information

Present Channel Data (Input Word 1)

This is a 32 bit unsigned long word value representing the current count of the 24 bit counter (configurations: count [0], x1 encoder [1],

x2 encoder [2], x4 encoder [4]) or the frequency (configurations: period/rate [5], rate measurement [7]). The range of values is 0 ≤ value

≤ 0x00FFFFFF (16,777,215).

Stored/Accumulated Channel Data (Input Word 2)

This is a 32 bit unsigned long word value representing the stored count of the counter at the time of some specified event. In counter configurations (configurations: count [0], x1 encoder [1], x2 encoder [2], x4 encoder [4]) without store modes selected, these words are not updated. With store modes selected, they are the stored value of the counter at the time of the specified event (ex: rising edge of Z input). In period/rate [5] configurations, it is the total accumulation of unscaled Z pulses (for example, if scaling is set to 128, after 128 Z pulses the accumulator will increase by 128 counts).

The maximum frequency that accumulation can follow in period/rate mode is 200Hz x scalar value (ex: 200Hz x 128 is 25kHz). Finally, in rate measurement [7] configuration, it is the total number of pulses seen at the A input accumulated over each period as specified by the product of the time base x gate interval. The range of values occupies the entire 32 bit size from 0 ≤ value ≤ 0xFFFFFFFF (4,294,967,295). Changing the configuration does not clear these words.

was programmed OR Multiple scalars were selected.

E5: The preset is out of range ( > 0x00FFFFFF). E4: A rollover of zero was programmed OR Rollover is out of

range ( > 0x01000000).

E3: A configuration requiring time base was selected and no gate

interval was set OR Gate interval is out of range ( > 200) OR Product of time base and gate interval is greater than 3 seconds.

E2: A time base was entered that is not a multiple of 10 OR Time

base is out of range ( > 3000, or 3 seconds).

E1: ZF/BF/AF were selected and no filter was programmed OR

Multiple filters were selected.

E0: A reserved configuration/mode was programmed.

EEPROM Fault status bit (EF) - If a fault is detected with the

EEPROM during power up tests, this bit is asserted to 1. It indicates that the content of the EEPROM has been corrupted, most likely caused by loss of power during an executing write.

Not Ready status bit (NR) - Whenever power is applied to the module, the hardware must be initialized. During this time, the NR bit will be asserted and the green module status indicator will flash.

Z input Status (ZS) - This bit indicates the present status of the Z input (1 indicates Z is ON, 0 indicates Z is OFF). This bit is unaffected by Z Invert, ZI, in the Counter Configuration word.

B input Status (BS) - This bit indicates the present status of the B input (1 indicates B is ON, 0 indicates B is OFF).

A input Status (AS) - This bit indicates the present status of the A input (1 indicates A is ON, 0 indicates A is OFF).

C[1,0] Stored data count - This count cycles through [ 0 0 ], [ 0 1 ], [ 1 0 ], [ 1 1 ], [ 0 0 ]… Each time the stored/accumulated count words are updated, C[1,0] is incremented. This featu re assumes the host’s sample rate (including network delay and program scan) is as fast or faster than the frequency of the event that updates C[1,0].

Publication 1734-UM006B-E N-P - August 2005

3-4 Input and Output Data

Zero frequency Detected (ZD) - This bit is operational when frequency configurations are programmed (configurations: period/rate [5], rate measurement [7]).

In period/rate [5] configuration, counts are acquired during the ON state of the Z input. At very low frequencies the counter saturates, indicating a ze ro frequency detect. The time it takes to determine a zero frequency in these two configurations can be as long as 6.7 seconds ( 16,777,216 counts x 1/5MHz x 2 half cycles of Z ).

In rate measurement [7] configuration pulses on the A input are counted over a sample interval specified by the time base. The time it takes to determine a zero frequency in this configuration will be determined by the sample interval, for example, time base = 0.300 second (300 milliseconds) to determine ZF.

3-6 Input and Output Data

Decimal Position (Configuration Word 3)

This byte changes the significant digits of the frequency or counter display.

In the frequency modes (period/rate [5], rate measurement [7]) for example, a -2 will move the decimal point left 2 places, dividing the frequency value by 100, a +1 moves it right, multiplying by 10. The firmware checks for placement to be in the range -4 ≤ value ≤ +2. A value outside the range will move the decimal point to the zero position and assert the programming error (PE) bit. Moving the decimal point to the left (negative), allows high frequencies, commonly present in rate measurement mode, to fit within a single 16 bit word. Moving the decimal point to the right (positive), allows low frequencies, commonly present in period and continuous rate modes, to have resolution displayed to 0.1Hz and 0.01 Hz. Frequencies sho uld be kept below 3.2kHz for 0.1Hz resolution and below 320Hz for

0.01Hz. Scalars of Z/128, Z/64, Z/32 and Z/16 should not be used when positioning is applied. 0 is the default setting.

In the counter modes (counter [0], x1 encoder [1], x2 encoder [2], x4 encoder [4]), it attenuates the counter display, for example, 20 divides count+1 by 20. The value may be in the range 0 < value ≤ 255. The result of requesting a number other than 1 performs the function: (COUNT + 1)/ATTENUATION. This is useful for scaling a large counter value to a smaller 16 bit value or a percentage. One is the default setting and zero reverts to 1 to prevent a divide by zero.

Word 4 is reserved.

Ti me Base and Gate Interval (Configuration Words 5 and 6)

The gate interval byte sets the counter’s gate intervall using the time base setting (16-bit word 5) as its time unit . (its resolution is determined by the time base). The actual gate interval is the product of the time base and the gate interval (ex: 50ms gate interval may be produced with a time base of 10 and a gate interval of 5 or a time base of 50 and a gate interval of 1). The maximum value of the product of time base x gate interval is 3 seconds. The gate interval must be entered when rate measurement [7] configurations are used. The maximum value is 200.

Publication 1734-UM006B-EN-P - August 2005

Input and Output Data 3-7

Scalar (Configuration Word 7)

This bytel scales the Z signal in the period/rate [5] configuration. If the filter is applied, then the filtered Z is scaled. Only one bit of the scalar should be set. Selecting a scalar will cause accumulated counts to be adjusted accordingly (selecting a scalar of 128 will increase the accumulated count by 128 after 128 Z pulses have been received). We highly recommend that anytime Z is scaled (divide by 2, 4, 8), the Z input should be filtered, otherwise, noise could cause erroneous frequency readings.

Rollover (Configuration Word 8)

This long word sets the number of counts the counter will accumulate before rolling over. For example, a value of 1000 will produce a count sequence of: 998, 999, 0, 1, 2… while incrementing or 2, 1, 0, 999, 998… while decrementing. Rollover is a 32 bit number with a useable range of 1 ≤ value ≤ 0x01000000 (16,777,216). In count [0], x1 encoder [1], x2 encoder [2] and x4 encoder [4] configurations, it should be specified to some non-zero value; and in period/rate [5], and rate measurement [7] configurations is a ‘don’t care’.

Preset (Configuration Word 9)

This long word sets the preset value the counter will be loaded with, when a Counter Preset, CP, command is issued. Preset is a 32 bit number with a range of 0 ≤ value ≤ 0x00FFFFFF (16,777,215).

Safe State Values (Configuration Word 10)

When either the host transitions to PROGRAM mode or a communication fault (broken network cable) occurs, the module copies the safe state word (counter control value) into its real-time working buffer. The definitions are identical to those described under Real-time Output Data.

Communicate Real Time/Nonreal Time Information

The Encoder/Counter Module uses several words to communicate real time input and output data as well as non-real time module information (such as description and revision) and configuration.

Assembly 101 is produced for a polled connection. Assembly 102 is produced for a Change Of State (COS) connection. Assemblies 103, 104, and 106 are by Explicit message only . Assembly 105 is co nsumed in a polled connection.
