Note to readers

Until PL7-PCL and PL7-PMS Version 5.0 software becomes available, TSX AEM 1613 modules are set-up using Text Blocks (for configuring and using the measurements).

Therefore the set-up procedures for V3 level PLCs and Model 40 V4 level PLCs is identical (as described in the Example in Sub-section 5.2).

As soon as PL7-PCL and PL7-PMS V5.0 software is available, the example in Subsection 5.3 for V4 level PLCs will be enhanced.

1.2 TSX AEM 1613 Module

1.2-1 Description

General

The TSX AEM 1613 is an analog input module with 16 low level inputs for 3-wire Pt100 probes. When used with these probes, the module will perform monitoring and temperature measurement functions or control continuous processes.

Process

Pt100:

4mA

Module

Voltage

Measurement

The measurement principle is an application of Ohms law. A 2 mA current is injected into the probe and the resulting voltage is measured on its terminals. To compensate for the resistance of the connection wiring, a compensation technique is used to remove the effect of the voltage drop on the line. An identical current is injected into the two wires, the third wire is used to transfer the currents to 0V.

With the same resistance level on both wires and the current generators paired with a precision of 1/10000, the voltage on the terminals of the operational amplifier will be identical to that on the probe terminals.

_____________________________________________________________________

The module comprises a single pair of current generators that are common to all 16 channels. A multiplexing system allows successive connection of each of the 16 probes to the current generators and to the measurement amplifier.

For a single channel, the acquisition time is 65 ms divided into:

• 25 ms to establish the current level in the probe,

• 40 ms for conversion.

General Introduction 1

_____________________________________________________________________

Safety

The inputs are protected against industrial interference and are electronically isolated from each other and from the internal PLC voltages. A grounding circuit uncouples the common reference for the channels.

Ease of use

The analog module requires no external power supply. Since the configuration is entirely defined by software and the functions are preprogrammed, the module is particularly easy to use.

Operating convenience

The modules and the terminal blocks can be inserted and removed while the system is powered-up. The PLC processor is continuously informed of the operating status of the module, and the user program can access all data for processing, if required.

___________________________________________________________________________________________

Bus Interface

Input stage: This comprises an overvoltage protection circuit and a filter on each channel to eliminate high frequency noise.

Multiplexer: The solid state multiplexer sequentially switches the channels to be converted. The number of operations is unlimited.

Amplifier: Amplifies the input voltages.

Analog/Digital converter: This VFC (Voltage Frequency Converter) converter combines the advantages of a double ramp converter (signal integration) with frequency transmission (simplified serial link).

Isolated serial connection : The complete analog measurement circuit is at the input reference voltage and is isolated from the PLC bus. The serial link is isolated by photocouplers. In the microprocessor, a counter circuit converts the frequency into a digital value (counting over 40 ms in 50Hz mode using a quartz crystal to control the time base). In parallel, the microprocessor controls the amplifier gain changes and the changes of multiplexer channel.

Processing: The micro-controller also manages the interface with the PLC, and corrects the analog measurements, based on correction factors calculated from the internal calibration circuits as well as setting the thresholds and tests.

The bus interface carries data exchanges with the PLC processor: transmission of analog measurements, reception of the configuration, etc.

2.2 Software Structure

2.2-1 General

The software structure of the TSX AEM 1613 module is in two parts:

• A common part, identical to all intelligent modules, which manages the data exchanges with the PLC processor

• A specific part which manages sampling (sequencing, conversion, correction of analog measurements, processing of measurements) and specific self-tests.

The software manages the standard interfaces:

• Discrete interface for transmitting channel fault data,

• Register interface for transmitting status data and threshold bits,

• Message interface for writing the configuration, reading the analog measurements, reading the fault bit strings, writing thresholds, etc,

• Extended register interface for transmitting measurement data and channel faults

(supported by TSX/PMX Model 40 PLCs).

______________________________________________________________________

2.2-3 Measurement Processing

The micro-controller performs the following processing:

• Linearizes the raw conversion value,

• Scales the linearized value (physical or "user" scale),

• Sets the thresholds,

• Tests for range overshoot and limits the value, if exceeded,

• Tests for sensor break.

______________________________________________________________________________________________________

2.2-4 Measurement Sampling

The module cycle time depends on its operating mode, defined during configuration.

This mode is a combination of two parameters:

"50Hz" and "60Hz" modes

- "50 Hz": conversion is performed over 40 ms or two 50Hz periods. This ensures that interference caused by the 50Hz supply is rejected as fully as possible.

- "60 Hz": conversion is performed over 50 ms or three 60Hz periods. This ensures that interference caused by the 60Hz supply is rejected as fully as possible.

"normal" and "controlled" modes

- "normal": the time taken to establish the current in the probe is 25 ms prior to the start of conversion.

- "controlled": this mode allows simulation of a Pt100 probe using a calibration device. Off the shelf calibration devices usually have a fairly long response time when supplied with pulsed current. The time required to establish the current in the probe is 550 ms prior to the start of conversion.

"50 Hz" or "60Hz" mode is selected when the configuration is set.

Switching between "normal" and "controlled" modes (and vice-versa) is performed via the register interface using an additional command word.

2.3 Types of Processing Available

2.3-1 Monitoring for Range Overshoot

The input range defines the normal limits of operation for the sensor connected to the input.

The declaration of the input range has two principle functions:

• The setting of the error detection limits, which detect range overshoots,

• Calculations for scaling.

The following table gives the range numbers (to be entered during configuration) and the corresponding normal usage scales, as well as the lower range overshoot limit LL and the higher range overshoot limit HL.

➀ The measured value is within the declared full scale input range:

LL = 0 The module supplies the exact value between 0 and +4000

HL = 0

➁ The measured value is within the extended full scale range which solves problems of sensor dispersion:

LL = 0 The module supplies the exact value between -90 and 0

HL = 0 or between 4000 and 4144

➂ The measured value is below the LL limit (- 9

C), an overshoot fault is detected and a fault data bit is sent to the user program:

LL = 1 The module supplies a value limited to -90

HL = 0

➃ The measured value is below the HL limit (+414.4

C), an overshoot fault is detected and a fault data bit is sent to the user program:

LL = 0 The module supplies a value limited to +4144

HL = 1

The user can access these fault bits via the Read BDEF request.

The discrete I/O interface also indicates the channels where an overshoot was detected

(1 bit per channel).

Wire or sensor breakage

If the wiring (wire breakage or short-circuit) or the sensor is faulty, the module will detect a fault.

It is not possible to distinguish a large range overrun (beyond the values given below), from a sensor failure or a wire breakage.

However, the module will continue to interpret the values that it measures, by considering them as a short-circuit or an open circuit.

Test validation conditions

If the electrical level as measured by the module is less than the lower limit of the selected range, the module will declare a short-circuit on this input:

The test is performed permanently on all of the inputs declared in the configuration.

When a fault is detected, the module will:

• Set the LL or HL bit to 1 (BDEF fault bit string) for the corresponding channel,

• Set the "channel fault" bit of the discrete I/O interface to 1.

2.3-2 Measurement Filtering

The module supports digital filtering for each channel.

Therefore the user can select a first order digital filtering for each channel with a time constant of 4, 16, 64, or 256 seconds.

The digital filtering performed is the same as that of a RC couple.

Example:

If a time constant of 4 seconds is selected.

The module will perform processing on the measurement value that is equivalent to:

T = RC = 4 s dB

2.3-3 Measurement Scaling

The TSX AEM 1613 module has two modes that can be used to scale measurement values: the "physical range" mode and the "user range" mode.

"Physical Range" Mode

This mode provides the user program with the measurement values in physical units that are coherent with the input range, according to the following conventions:

"User Range" Output

This mode provides the user program with the measurement values as a percentage of the scale configured by the user in physical units within the selected range.

The "user range" can be configured channel by channel. The measurement values provided by the module are between 0 and 10,000 (or 0% and 100% of the range specified by the user in physical units).

The values set for triggering the LL and HL bits depend on the range selected and on the variation of the selected "user range".

If any limit overshoot occurs, the user range provides values that are proportional within the range ] -200 %, 0 % [ and ] 100 %, 200 %[. In the example below, -200 % corresponds to a temperature of -40

C, and + 200 % a temperature of +80

Operation 2

______________________________________________________________________

2.3-4 Threshold Detection

Two thresholds are defined for each channel.

The thresholds are programmable numerical values (expressed in the measurement unit corresponding to the type of scaling selected) that are set by the user and sent to the module via the message interface.

The result of threshold detection is provided on 2-bits that can be used by program, they are set to 1 when the measurement value exceeds the corresponding threshold (refer to Sub-section 4.3).

Comparisons are performed between the channel measurement value and the thresholds 0 and 1, each time a new input value is acquired. When a channel is not used, the results of the comparisons made are forced to 0.

The comparison performed for each threshold automatically compensates for hysteresis (h) equal to 0.5% of the declared scale. The value with which the measurement is compared depends on whether the analog input signal is rising or falling:

• For a rising input signal, the detection bit is set to 1 when the measurement is greater than the threshold plus h/2,

• For a falling input signal, the detection bit is set to 1 when the measurement is less than the threshold minus h/2.

2.4 Dialog with the PLC

2.4-1 General

There are four types of data exchange with the PLC processor via the complete I/O bus:

• Discrete I/O interface, with address Ixy,i

• Register interface, with address I/OWxy,i

• Message interface

• Extended register interface (READEXT instruction) x = Rack number y = Slot number in the rack i = See later in this document

For each of these data exchanges there are corresponding data objects which can be utilized by the user program. The extended register interface is only available on

TSX/PMX Model 40 processors.

_____________________________________________________________________

2.4-2 Discrete I/O Interface

TSX AEM 1613 modules have a 16 input discrete interface.

The user can access 16 bit objects as well as the fault bit via the program.

Data exchanges are systematically performed during each task cycle in which the module is configured.

The interface indicates the status of the 16 fault bits, one for each channel. At 1 they indicate that the corresponding channel has an input value that is outside of the valid range defined by the higher (HL) and lower (LL) limits.

______________________________________________________________________

2.4-5 Message Interface

The message interface is used to transfer data tables between the module and the PLC processor. The transfer is programmed via a CPL text block and is initiated by the user program.

This type of dialog is used to:

• Write the configuration,

• Re-read the configuration,

• Read the measurements and their associated faults,

• Write the threshold values,

• Re-read the threshold values.

Data specific to each transfer is organized into internal words (Wi) or constant words,

CWi, (for transmission only).

A more detailed description of programming using the message interface is given in the sections relating to each exchange:

• Configuration (Section 3),

• Reading measurements (Sub-section 4.1),

• Writing thresholds (Sub-section 4.3),

• Processing faults (Sub-section 4.4-1),

• Additional requests (Sub-section 4.4-2).

Initial

Self-Test

➤ Module

Module

Configuration

➤ 3

On power-up, initialization request or after a power-break, the module runs an initial selftest procedure ➀ .

If no fault is detected during this procedure, the module then goes to RUN or STOP mode

(depending on the value of the standard control word) using the default configuration.

To use the module under application conditions, it must be configured. To do this the user must program the following:

• Set the module to STOP ➂ ,

• Send the configuration via the message interface ➄ ,

• Reset the module to RUN ➅ .

If the configuration received is faulty or incomplete, the module waits until a valid configuration is received ➄ .

The use of configuration loading OFBs provided with TXT L PL7 PCL and TXT L PL7 PMS

(1) program packages (only for use with TSX/PMX Model 40 PLC processors) simplifies the programming of loading operations for the user.

Once configured and running (module running), the module is ready to sample measurements.

Standard discrete data, register and extended register data are exchanged during each task cycle in which the module is configured.

(1) Version 5.0 or higher.

______________________________________________________________________

2 7

______________________________________________________________________

2.5-2 Controlling the Operating Modes

The user has access to a control register word which is used to force the module into the required operating mode.

The status register words give information on the operating mode of the module:

• Initial self-test,

• RUN/STOP module,

• Awaiting configuration ➃ ,

• Operating with the default configuration.

_____________________________________________________________________

2.5-3 Module Reaction to a Power Break

The TSX AEM 1613 module does not have a protected memory. All data is lost (including the configuration and the threshold values), when the module is disconnected from the power supply provided by the PLC.

The module must therefore be reconfigured and the threshold values reprogrammed in the event of:

• A cold restart (SY0 = 1),

• A hot restart, when the power supply reserve has been exhausted,

• When the module is installed in the PLC.

The various types of restart are described in the appropriate PL7-3 Reference Manuals.

Additional status word bit (IWxy,2,D) indicates when the module is operating with the default configuration. This bit can thus be used to detect the loss of the configuration, and to request that the configuration specific to the application is transferred again (refer to the example in Section 3).

_____________________________________________________________________

2.5-4 Effect of Faults on the Operating Modes

When an acquisition or conversion fault is detected on the module, it changes to STOP mode, and remains in this mode until the fault disappears.

When an application (sensor or wiring) fault is detected, the module continues to operate in RUN mode.

3.1 Principle

3.1-1 General

Configuration data lets the user adapt the modules to a given application. Selection of the most suitable configuration simplifies the programming required to make use of the measurements provided by the modules. This data defines the operating mode of the module and of each of its channels.

Configuring a module comprises:

• Defining the operating characteristics of the modules,

• Coding these characteristics, in hexadecimal codes or decimal values,

• Transferring the codes and values to the module via a program.

Reminder

The "traditional" method of setting-up TSX AEM 1613 modules, the only means of set -up available for V3 level PLCs (TSX P43-30/67-20/87-30), is covered in Sub-sections 3.1 to 3.4.

The is also the only method that can be used by systems without PL7-PCL and PL7-PMS V5 level software.

The recommended set-up method for TSX/PMX Model 40 PLCs and TXT L PL7 PCL/PMS software is given in Sub-section 3.5.

_____________________________________________________________________________

• The operating mode

• The type of processing for each channel

Zone 1

Zone 2

Zone 3

Zone i + 2

Zone 17

Configuration data should be coded in a word table located in the W (internal words) zone via a program or in the CW (constant words) zone.

____________________________________________________________________

3.1-3 Default Configuration

The TSX AEM 1613 module has a default configuration which enables it to operate immediately when powered-up.

The main function of the default configuration is to test the wiring. It is described in detail in Sub-section 3.3.

The default configuration is replaced by the user configuration as soon as it is transmitted by the user program.

___________________________________________________________________________

3 0

Configuration 3

___________________________________________________________________________

3.1-4 Transmission of Configuration Data

Once the configuration data has been coded and stored, it must be transmitted to the module.

The configuration data is transmitted from the PLC memory to the module memory via a program (using a CPL text block).

The following procedure must be used to transmit the configuration:

• Stop the module (STOP),

• Wait until the module has stopped,

• Send the configuration via a CPL text block,

• Restart the module (RUN).

Power-up Module

Module RUN with default configuration

Module STOP

If Module STOP send user configuration

Note: The configuration may be lost if there is a power break or if the module is removed from its slot. If this happens, the configuration must be sent again.

Module RUN

_____________________________________________________________________

3.1-5 Bits Associated with the Configuration

Two bits, in the standard and additional status words (and which can be accessed via a program) are associated with module configuration:

IWxy,0,B: At state 1 this bit indicates that the module is awaiting configuration (in the event of an invalid configuration being received).

IWxy,2,D: At state 1 this bit indicates that the module is operating with the default configuration.

Words 2 and 3: These words must in all cases be sent to the module but are only significant if the module is parametered for user range operation.

1 a

Zones 2 to 17 b c d

2 Value for 100 %

• If word 2 > Word 3

These words indicate the values (expressed in the physical range) that define the limits to user scaling

- Word 2 = physical value corresponding to 100%,

- Word 3 = physical value corresponding to 0%.

Value for 0 %

• If word 2 < word 3

The module will wait for a valid configuration (bit IWxy, 0, B to 1).

___________________________________________________________________________

3 3

___________________________________________________________________________

3.3 Default Configuration

The module has a default configuration which is mainly used to check for correct operation and correct connection.

The default configuration is operational as soon as the module is powered up.

Additional status word bit IWxy,2,D indicates whether the module is operating with this configuration:

IWxy,2,D = 1

→

Default configuration

With the default configuration, the module operates in 50 Hz mode, the 16 channels are configured identically:

- Input range -50/+150

- No filtering,

- Physical unit scaling.

Zone 1

Zones

2 to 17

A 0

B Ch. Nbr

If there is a power break or the module has been removed and replaced, the configuration is lost and is replaced by the default configuration.

If the default configuration is acceptable for a channel, there is no need to retransmit the configuration.

___________________________________________________________________________

Configuration 3

___________________________________________________________________________

3.4 Loading the Configuration

3.4-1 Entering Data

When the module configuration data has been defined and the corresponding codes determined, the codes must be stored in the PLC memory before they can be transferred to the module.

This can be performed in the W zone, but it is preferable to use the CW zone.

The screen below shows an example of a configuration.

Hexadecimal codes are preceded by the letter H.

______________________________________________________________________

3.4-2 Transferring the Configuration to the Module

When the configuration data has been stored in the PLC memory, it must be transferred to the module memory. For this, the user must program a transmission reception text block.

PLC Application

! EXCHG TXT

TXT

CPL

Module

Text block characteristics

• TXTi,M : H’ . . 63' The configuration concerns the module system

Slot number

Rack number

• TXTi,C : H’0040' Request code informing the module that configuration data is being sent.

• TXTi,L : 98 Transmission table length, corresponding to the number of bytes in the table that contains the configuration data:

98 bytes.

___________________________________________________________________________

3 5

___________________________________________________________________________

The confirmation report, TXTi,V, sent back by the module can be used after the data exchange to check that the data has been transmitted correctly. It is H’FE’ if the data exchange is correct, and H’FD’ if not.

Programming the transfer

The transfer should be programmed in the following way:

• Stop the module by setting control register bit OWxy,0,C to 0,

• Check that the module has stopped by testing that status word bit IWxy,0,C is at 0,

• Then transfer the configuration. To do this, generate a rising edge on the S input of the text block,

• To check that the transfer has been successful:

- Check that TXTi,E is at 0,

- Check that TXTi,V is H’FE'.

• If the configuration has been successfully received, reset the module to Run mode by setting the control register word bit OWxy,0,C to 1.

Bit IWxy,0,C should then change to 1.

Module Stopped

Module Running

STOP Module

_____________________________________________________________________________

3.4-3 Checking the Configuration

The configuration is not accepted by the module if:

• The length of the configuration is incorrect,

• The syntax is incorrect (code not defined),

• The selections made in the configuration are incompatible,

• The module is running (set to Run).

Transmission of an incorrect configuration

Transmission of an incorrect configuration causes the status word bit IWxy,0,B "awaiting configuration" to change to 1. The module then awaits a new configuration and the previous correct configuration remains in its memory.

Configuration 3

___________________________________________________________________________

3.5 Configuring the Module Using PL7-PCL or PL7-PMS Software

3.5-1 General

Setting-up a TSX AEM 1613 module is simplified by using PL7-PCL or PL7-PMS (1) software, providing:

• An operator guide program which enables the user to enter module configuration parameters from an X-TEL workstation (input ranges, type of scaling, etc).

For this, it presents all the parameters in the form of a table with the type, limits and definition of each parameter.

This program also provides for:

- Transfers of the parameters between the module, PLC, disk or diskette.

- Print-outs of the parameters.

- Display of parameter changes (measurement of each channel, operating modes, faults, etc).

It uses the dedicated zone technique supported by TSX/PMX Model 40 PLCs.

• Two optional function blocks (OFB) specific to the processing of analog measurements which have been added to the other PL7-3 function blocks:

- ANALD (2) for loading the module configuration following a power break or when a module has been replaced.

- ANADG (2) used to monitor for faults which may occur on modules while operating

(for example terminal block fault) or on applications controlled by these modules (for example sensor break). Faults detected in this way are formatted for use by the

APPLIDIAG program (in the Software Workshop) or the DIAG program (when using

MONITOR 37).

Restrictions

PL7-PCL software can only by used on Model 40 PLCs, version 4.3 or higher. PL7-PMS software can only be used on PMX type PLCs.

(1) Only version V5.0 or higher of PL7-PCL and PL7-PMS software is compatible with TSX AEM 1613 modules. Configuring TSX AEM 1613 modules using this software is therefore only available to users of X-TEL or MINI X-TEL V5 level Software Workshops.

This operating mode is the only one accessible to TSX Series 7 V3 level PLCs

(TSX P47-30/67-20/87-30).

____________________________________________________________________

4.1-1 Accessing the Measurements

In message mode the measurements are transmitted in 16 internal words (Wi) in response to the request "Read measurements".

This request is programmed using a CPL type text block in transmit/receive mode, with the following characteristics:

• Request code : TXTi,C = 1

• Address : TXTi,M = H’xy00’ (where x = Rack nbr. and y = Slot nbr.)

• Reception table: Wi[16] table of 16 words (32 bytes) containing the 16 measurements

(where Wi = channel 0 measurement, Wi+ 1 = channel 1 measurement, and so on, to Wi+ 15 = channel 15 measurement).

• It is not necessary to define a transmission table.

Confirmation reports: TXTi,V = H’81' if exchange correct, or H’FD’ if incorrect.

TXTi,S = 32 bytes if exchange correct (TXTi,E = 0).

Note:

If the module is stopped, the measurements transmitted are not actual measurements, but the last measurements acquired before the module was stopped.

Conditions for validity and the digital-analog correspondence of the measurements are identical to those for accessing measurements in extended register mode (refer to

Sub-section 4.2).

4.2 Using the Measurements in Extended Register Mode

4.2.1 Accessing the Measurements

This new fast data exchange mode is only available with TSX/PMX Model 40 processors, version 4.3 and higher. In this mode, measurements are transmitted by immediate reading of 17 internal words (Wi):

Wi + 1

Wi + 2

Channel Status

Measurement Ch. Ø

Measurement Ch. 1

Wi + 15

Wi + 16

Measurement Ch. 14

This data exchange mode is programmed in PL7-3, using the immediate read instruction

READEXT (Ixy; Wi; Wj), where:

• Ixy Geographical address of the TSX AEM module

• Wi

• Wj= 17

Start of the table

Length of the table in number of words

Note

The extended register data exchange mode is only active if the module is in RUN mode. If the module is stopped, the measurements transmitted are the last measurements acquired before the module was stopped.

Operating Information

______________________________________________________________________

4.2-2 Conditions for Measurements to be Valid

The digital values effectively represent the measurements expected from the analog measurements, provided the following conditions are met:

_________________________________________________________________________________________

Status Consequences

Module running IWxy,0,C = 1 If the module is stopped, the values read are the last values received before the

Module configured IWxy,2,D = 0 If not configured, the module takes the default configuration. The measurements

Input values are within limits of the extended zone, with correct sensor and wiring

Wi, k = 0

(k = 0 at H'10')

Wi = destination address of the

Module operating correctly Ixy,S = 0

If the channel is faulty the measurement the read is incorrect.

When this bit is at 1, the module changes to STOP.

Example:

The actual measurement for channel 1 is only used if the module is OK, configured, and if no channel fault is detected.

The module is in slot 5 in the rack. The measurement is stored in W11. W11.

4.3 Using Thresholds

The TSX AEM 1613 supports the detection of two programmable thresholds per channel

(refer to Sub-section 2.3.4). This function is run in two phases:

• Transmission of thresholds to the module,

• Processing the results of threshold detection.

______________________________________________________________________

4.3-1 Transmission of Thresholds to the Module

The thresholds must be transmitted to the module via the message interface, using two specific requests: write threshold 0 request (channels 0 to 15), write threshold 1 request

(channels 0 to 15).

These two requests are programmed using the CPL text block in transmission reception mode, with the module stopped or running and the following characteristics set:

• Request code: TXTi, C = 2 (for 0 thresholds), TXTi, C = 4 (for 1 thresholds)

• Address: TXTi,M = H’xy00' (with x = rack number; y = slot number)

• Transmission table: TXTi,L = 32

CWi(16) or Wi(16) comprising the threshold values to enter in constant or data mode by program, with:

- (C)Wi = Threshold channel 0,

- (C)Wi+1 = Threshold channel 1,

- ...

- (C)Wi+15 = Threshold channel 15,

• No reception table need be defined.

Threshold values

The values of the thresholds must be between +32,767 and -32,768 but is restricted to the valid measurement range in the selected scaling range.

Thresholds are expressed in the measurement unit defined by the type of scaling: in physical units or in user defined units, depending on the selection made when the configuration was selected.

By default, or after a power-break, the threshold bits for each channel are set to 0. The threshold values must be returned to the modules (refer to Sub-Section 2.5-3).

The bit assigned to one of the thresholds of a channel will be set to 1 when the measurement value on the appropriate channel exceeds the programmed threshold value plus half of the hysteresis value. It is set to 0 when the measurement value on the appropriate channel falls below the programmed threshold value minus half of the hysteresis value.

The hysteresis value depends on the scaling selected (refer to Sub-Section 2.3.4).

Note: When a channel is not used, the threshold detection bits assigned to it are forced to 0.

______________________________________________________________________

4.3-3 Modifying the Threshold Values

The threshold values can be modified:

• When the module is stopped. When the application allows it, this is the recommended procedure. This avoids any interpretation errors affecting the detected thresholds

(new or old threshold values).

• When the module is running. In this case, threshold detection with new values is only taken into account:

- When the response to the request sent by the text block has been received, TXTi,D reset to 1 and report TXTi,V = H’FE’,

- After a sampling cycle of all 16 channels.

The selection of the moment when the results of the threshold detection are taken into account (if this is important for the application), is up to the user.

The loading and modification of thresholds can be performed by text block from the application program (refer to the Additional Programming Information sub-section), or from the terminal using PL7-PCL or PL7-PMS set-up software.

4.4 Additional Programming Information

4.4-1 Fault Processing (Optional)

The user can use a program to accurately identify faults occurring on a TSX AEM 1613 module or in its external environment.

Type of faults

Faults which occur on a TSX AEM 1613 module can be divided into three categories, according to their seriousness and their effect on module operation:

• Blocking faults:

This type of fault corresponds to a failure detected in the module processor the interface with the bus. The module processor is inhibited and no data exchange is possible on the bus.

• Module acquisition and conversion faults:

These faults are caused by:

- The electronic circuits in the module that perform the acquisition and conversion of measurements,

- An absent terminal block.

The measurement values are no longer valid and the module is forced to stop.

• Application faults:

These faults correspond to failures caused by the external environment of the module

(range overshoot, sensor failure, etc.). They may occur on one channel only, while the other channels continue to operate correctly. The faulty channel is indicated to the user.

______________________________________________________________________

Fault detection

There are a number of methods of fault identification available to the user:

• Indicator LEDs

• Fault bits

• The 25-pin male SUB-D connector when only a single group of 8 channels is used (a missing connector on the other group has no effect).

Reminder: A terminal block fault forces the module to stop.

Programming and reading the fault bit string

The fault bit string is read via the text block. It is optional and its main purpose is the accurate location of faults.

The content of the bit string is described on the preceding pages.

The action of reading the fault bit string

(BDEF) acknowledges a fault detected by bits IWxy,0,4, and IWxy,0,i (i = 6 or 7), after it has disappeared, whether the reading takes place before or after the disappearance of the fault.

IWxy,0, bit 4,6 and 7 change to zero:

• When the fault disappears, if they have been acknowledged by reading the fault bits.

• When the fault bits are read after the fault has disappeared.

The message read after detection of fault nbr. 1 will not contain fault nbr. 2.

Error

IWxy,0,i

IWxy,0,4

Error 1

Error 2

BDEF

The user will not be informed of the second fault IWxy,0,4 and IWxy,0,i = 1, (i = 6 or 7) until the first fault has disappeared. Thus fault nbr. 2 can only be acknowledged after a new reading of the fault bit string.

It is therefore necessary to sample the fault bit string continuously to detect the appearance or disappearance of new faults.

Error 1

Error 2

How the received bit string is used depends on the user's requirements. The user may simply wish to keep the bits in internal words and read them in Adjust or Data modes on the programming terminal. Or the user may wish to store them in word tables so that the condition of faults can be displayed.

Re-reading the configuration consists of transferring the configuration data from the module memory to the PLC memory. The configuration is read as a whole.

For this, the user must program a transmit/receive text block.

Characteristics of the text block

The text block should have the following characteristics:

• CPL type: To enable exchange between the user program and the module.

• Request code : TXTi,C = H’41'

• Address and channel number:

TXTi,M = H’xy63'

• It is not necessary to define a transmission table.

TXTi,L = 0

• The reception table length must be 98 bytes to be able to receive the whole configuration.

5.1 Description

_________________________________________________________________________________________________________________________

The application described in this example checks the temperature dissipation of electronic devices subject to a burn-in cycle in an oven.

Each oven has a Pt 100 probe that measures the oven temperature, controlled using discrete I/O logic. Three probes are used to measure the temperature of points in the devices where the highest levels of heat dissipation occurs. In order to justify the use of a

TSX AEM 1613 module, let us assume that four ovens must be monitored.

Pt2

The oven temperature check requires that the door be closed. The temperature must be held at 80

° ±

C. The acquisition of "hot spot" temperature measurements only takes place once the oven reaches 80

for the first time after closing the door. It will stop as soon as the door is opened.

Channels 16 to 19 of the TSX DST 2472 output module in slot 7 of the extension rack control the oven heater resistances.

Channels 20 to 23 of this module control an indicator that is lit when an error caused the cycle to be stopped.

____________________________________________________________________

________________________________________________________________________________

TSX AEM 1613 module configuration

All 16 channels are configured in the same way:

• 50Hz operating mode,

• -50 / +150

C input range,

• No filtering,

• Physical range scaling (in hundreds of degrees).

Note

How the configuration parameters are encoded and transferred to the module depend on the type of PLC processor selected (text block for V3 level PLCs - refer to Sub-section 5.2, or OFBs for V4 level and higher PLCs - refer to Sub-section 5.3).

The configuration is systematically reloaded each time a power break occurs or when the module is plugged into the rack. These two situations are tested by setting the

"Module Ready" bit (IW5, 0, 3) to 1 at the end of the self-test cycle.

Suggested processing

The acquisition speed is 1.3 seconds (for 16 channels in 50Hz mode) it is usual to adopt an identical time period for processing. Task AUX0 will be used for processing (for acquiring the measurements, monitoring the oven and storing the hot spot temperatures).

To use the processing capacity built-into the module, the threshold data provided by

Threshold monitoring is performed with hysteresis of 0.5% of the full scale input range, or 1 ° C when the -50/+150 ° C range is selected, requiring that the following values be defined to ensure rigorous measurement results:

• 82

C (or 8200) for the higher threshold,

• 78

C (or 7800) for the lower threshold.

Note

In the example, no allowance is made for problems related to the size of the storage buffers, nor for using the measurement values stored in these buffers.

5.3 Implementing on a V4 Level PLC

A TSX Series 7 Model 40 PLC can be programmed in the same way as a V3 level PLC

(refer to Sub-section 5.2).

However, it is preferable to use PL7-PCL or PL7-PMS (1) software for improved easeof-use when setting-up TSX AEM 1613 modules. In addition TSX Series 7 Model 40

PLCs support an improved mechanism for returning measurement values (using the

READEXT instruction).

(1) Setting-up TSX AEM 1613 modules requires the user of version V5.0 of PL7-PCL or PL7-PMS programs. This version is currently under development. It should be available during the 4th.

6.2-2 Connection Principles

It is advisable to take the following precautions to protect the signal from induced outside noise in serial mode and from common mode noise:

Type of cable

Given the importance that variations in line impedance levels can have, depending on the distance, the wires used must be selected so that the line resistance

RL < 20

Ω

For example: using wire with a cross-section of 0.22 mm 2 allows connections over 200 meters max.

Cable screening

Twisted pair cables with separate screening should be used for connecting the connector block and the sensors.

The cable screening should be connected to the PLC earth (ground) through the terminals reserved for this purpose on the ABE-6SD2520 connector block.

The shielding can be connected at both ends (connector block and sensor) if the installation site has a suitable grounding network (grounding network using 35 mm 2 cross-section cable).

6.2-3 Referencing Channel Inputs and Sensors

The TSX AEM 1613 module has 16 inputs which have a common point but are isolated in relation to the PLC bus.

For safety reasons, the module has a capacitor between the channel reference voltage and ground. This ensures that any brief spikes are absorbed.

It is preferable to use "floating" sensors (not referenced to ground).

Example below: wiring of a floating sensor.
