INTRODUCTION

The IF303 is a converter mainly intended to interface analog transmitters to a Profibus PA network. The IF303 receives up to three current signal typically 4-20 mA or 0-20 mA, and makes them available to Profibus PA system. The digital technology used in the IF303 enables an easy interface between the field and the control room and it has several interesting features that reduce considerably the installation, operation and maintenance costs.

The IF303 is part of SMAR's complete 303 line of Profibus PA devices.

Profibus PA, is not only a replacement for 4-20 mA or intelligent/smart transmitter protocols, it contains much more.

The digital technology used in the IF303 enables the choice of several types of transfer functions, an easy interface between the field and the control room and several interesting features that considerably reduce the installation, operation and maintenance costs.

Some of the advantages of bi-directional digital communications are known from existing smart transmitter protocols: Higher accuracy, multi-variable access, remote configuration and diagnostics, and multi-dropping of several devices on a single pair of wires.

The system controls variable sampling, algorithm execution and communication so as to optimize the usage of the network, not loosing time. Thus, high closed loop performance is achieved.

Using Profibus technology, with its capability to interconnect several devices, very large control schemes can be constructed. In order too be user friendly the function block concept was introduced

The IF303, like the rest of the 303 family, has some Function Blocks built in, like Analog Input and Totalizer Blocks.

The need for implementation of Fieldbus in small as well as large systems was considered when developing the entire 303 line of Profibus-PA devices. They have common features and can be configured locally using a magnetic tool, eliminating the need for a configuration tool or console in many basic applications.

Get the best result of the IF303 by carefully reading these instructions.

INSTALLATION

NOTE

The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14 standard.

The overall accuracy of measurement and control depends on several variables. Although the converter has an outstanding performance, proper installation is essential, in order to maximize its performance.

Among all factors, which may affect converter accuracy, environmental conditions are the most difficult to control. There are, however, ways of reducing the effects of temperature, humidity and vibration.

Locating the converter in areas protected from extreme environmental changes can improve the converter performance.

In warm environments, the converter should be installed to avoid as much as possible, direct exposure to the sun. Installation close to lines and vessels subjected to high temperatures shou ld also be avoided.

Use of sunshades or heat shields to protect the converter from external heat sources should be considered, if necessary.

Humidity is fatal to electronic circuits. In areas subjected to high relative humidity, the O-rings for the electronics cover must be correctly placed. Removal of the electronics cover in the fiel d should be reduced to the minimum necessary, since each time it is removed the circuits are exposed to the humidity. The electronic circuit is protected by a humidity proof coatin g, but frequent exposures to humidity may affect the protection provided. It is also important to keep the covers tightened in place. Every time they are removed, the threads are exposed to corrosion, since painting cannot protect these parts. Code-approved sealing methods on conduit enteri ng the converter should be employed.

Using the bracket, the mounting may be done in several positions, as shown on Figure 1.3 Dimensional Drawing and Mounting Positions.

For better visibility, the digital indicator may be rot ated in steps of 90° (See Section 4 - Maintenance Procedures).

Access the wiring block by removing the Electrical Connection Cover. This cover can be locked closed by the cover locking screw (See Figure 1.1 - Cover Locking) To release the cover, rotate the locking screw clockwise.

Cable access to wiring connections is obtained by one of the two conduit outlets. Con duit threads should be sealed by means of code-approved sealing methods. The unused outlet connection should be plugged accordingly.

The wiring block has screws, on which fork or ring type terminals can be fastened, see Figure 1.2 Terminal

Block.

The IF303 uses the 31.25 kbi t/s voltage mode option for the phys ical signaling. All other devices on the same bus must use the same signaling.

Various types of Fieldbus devices may be connected on the same bus. The IF303 is powered via the bus. The limit for such devices is according to the DP/PA coupler

limitations for one bus (one segment) for non-intrinsically safe requirement. In hazardous area, the number of devices ma y be limited by intrins ically safe restrictions, according

to the DP/PA coupler and barriers limitations. The IF303 is protected against reverse polarity, and can withstand ±35 VDC without damage, but it

will not operate when in reverse polarity.

Bus topology (See Figure 1.4 - Bus Topology) and tree top ology (See Figure 1.5 - Tree Topology) are supported. Both types have a trunk cable with two terminations. The devices are c onnected to the trunk via spurs. The spurs may be integrated in the device giving zero spur length. A spur may connect more than one device, depending on the lengt h. Active couplers may be used to extend spur length.

Active repeaters may be used to extend the trunk length. The total cable length, including spurs, between any two devices in the Fieldbus sho uld not exceed

1900m. The connection of couplers should be kept less than 15 per 250m. In folowing figures DP/PA link

Intrinsic Safety Barrier

When the Fieldbus is in an area requiring intrinsic safety, a barrier must be inserted on the trunk between the power supply and the DP/PA coupler, when it is Non-Ex type.

Use of DF47 is recommended.

Jumper Configuration

In order to work properly, the jumpers J1 and W1 located in the IF303 main board must be correctly configured (See Table 1.1 - Description of the Jumpers).

J1 This jumper enables the simulation mode parameter in the AI block.

W1 This jumper enables the local adjustment programming tree.

Power Supply

The IF303 receives power from the bus via the si gnal wiring. The power supply may come from a separate unit or from another device such as a controller or DCS.

The voltage should be between 9 to 32 Vdc for non-intrinsic safe applications. A special requirement applies to the power supply used in an intrinsica lly safe bus and depends on

the type of barrier used. Use of PS302 is recommended as power supply.

Section 2

OPERATION

The IF303 accepts signals from mA generators such as most conventional transmitters. It is therefore ideal for interfacing existing equipment to a Fieldbus system.

Functional Description – Electronics

See Figure 2.2 - IF303 Block Diagram. The function of each block is described below.

MUX Multiplexer

The MUX multiplexes the input terminals to ensure that all three channels reach the A/D converter.

A/D Converter

The A/D converts the input signals to a digital format for the CPU.

Signal Isolator

Its function is to isolate the data signal between the input and the CPU.

(CPU) Central Processing Unit, RAM and FLASH

The CPU is the intelligent portion of the converter, being responsible for the management and operation of block execution, self-diagnostics and comm unication. The program is stored in Flash memory. For temporary storage of data there is a RAM. The data in the RAM is lost if the po wer is switched off, however the device also has a nonvolatile EEPROM where data that must be retained are stored. Examples of such data are: calibration, configuration and identification data.

Communication Controller

It monitors line activity, modulates and demodulates the signal from network line.

Power Supply

Takes power of the loop-line to power the converter circuitry.

Power Isolation

Just like the signals from the input section, the power to the input section must be isolated.

Display Controller

Receives data from the CPU and drives the Liquid Crystal Display.

Local Adjustment

They are two switches that are magnetically activated. They can be activ ated by the magnetic tool without mechanical or electrical contact.

Section 3

CONFIGURATION

One of the many advantages of using Fieldbus technologies is that device configuration is independent of the configuration software. The IF303 may be configured by a third party terminal or operator console as Smar’s configurators ProfibusView or AssetView for FDT.

The IF303 contains three input transducer blocks, one ph ysical block, on e display transdu cer block , three analog input and three totalizer function blocks.

Function Blocks are not covered in this manual. For further explanation and details of function blocks, see the “Function Blocks Manual”.

In order to assure correct values in the offline configuration, when using download function of Simatic PDM, please make sure you have done the upload firstly.

Offline Configuration

1. First run “Download to PG/PC” option to assure valid values.

2. Run after the Menu Device option to configure the required parameters using the related menus.

It is not advisable to use the “Download to Device” option. This function can misconfigure the equipment.

Transducer Block

Transducer block insulates function block from the specific I/O hardware, such as sensors and actuators. Transducer block controls access to I/O through manufacturer specific implementation. This permits the transducer block to execute as frequently as necessary to obtain good data from sensors without burdening the function blocks that use the data. It also insulates the function blocks from the manufacturer specific characteristics of certain hardware.

By accessing the hardware, the transducer block can get data from I/O or passing control data to it. The connection between Transducer block and Input/Output Function blocks is called channel. Normally, transducer blocks perform functions, such as linearization, characterization, temperature compensation, control and exchange data to/from hardware.

How to Configure a Transducer Block

The transducer block has an algorithm, a set of contained parameters and a cha nnel connecting it to a function block. The algorithm describes the behavior of the transducer as a data transfer functio n between the I/O hardware and other function block. The set of contained parameters, it means, you are not able to link them to other blocks, defines the user interface to the transducer block. They can be divided into Standard and Manufacturer Specific.

The standard parameters will be present for such class of device, as pressure, temperature, actuator, etc., whatever is the manufacturer. Oppositely, the manufacturers specific ones are defined only by its manufacturer. As common manufacturer specific parameter s, we have calibration settings, material information, linearization curve, etc.

When deforming a standard routine as a calibr ation, user is conducted step by step by a method. The method is generally defined as guide line to help the user to make common tasks. The Configuration Tool identifies each method associated to the parameters and enables the interface to it.

Terminal Number

It is the parameter, which makes reference to a physical input, which in the turn, is sent internally from the specified transducer output to function block.

It starts at channel one (1) for transducer number one until channel three (3) for transducer number three.

NOTE

3.1

IF303 – Operation and Maintenance Instruction Manual

The channel number of the AI block and TOT block is related to the transducer’s terminal number. Channel number 1, 2, 3 corresponds bi-univocally to the terminal block with the same number. Therefore, all user has to do is choosing c ombinations: (1.1), (2.2), (3,3) for (CHANNEL, BLOCK) respectively.

IF303 - CYCLIC CONFIGURATION

The PROFIBUS DP and PROFIBUS PA protocols have mechanisms against communication failures between the slave device and the network master. For example, during initialization, these mechanisms are used to check these possible errors. After po wering up the field device (slave), it can cyclically exchange information with the class 1 mast er, if the parameterization for the slave is correct. This information is obtained using the GSD files (supplied by the device man ufacturer, it contains their descriptions). Through the commands below, the master executes all initialization process with the PROFIBUS PA device:

 Get_Cfg: uploads the slave configuration on the master and checks network configuration;  Set_Prm: writes to the slave parameters and executes the parameterization network;  Set_Cfg: configures the slaves according to i ts outputs and inputs;  Get_Cfg: another command, where the master checks the slave configuration.

All these services are based on the information obt ained from slave gsd files. The GSD file from IF303 shows details such as, hardware and software revision, device bus timing and i nformation about cyclic data exchange.

IF303 has 6 function blocks: 3 AIs (Analog Input) and 3 TOTs (Totalizer). It also has the empty module for applications where not all function blocks are necessary. The following cyclic order of the blocks should be respected: AI_1, AI_2, AI_3 and T OT_1, TOT_2, TOT_3. Suppose, only the AIs blocks are necessary, then configure this way: AI_1, AI_2, AI_3, EMPTY_MODULE, EMPTY_MODULE, EMPTY_MODULE.

Nevertheless, if you want to work only 1 AI and 1 TOT, configure them this way: AI_1, EMPTY_MODULE, EMPTY_MODULE and TOT_1, EMPTY_MODULE, EMPTY_MODULE.

Most PROFIBUS configuration tools use two directories where the different manufacturers’ GSD’s and BITMAPS files are stored. The GSD’s and BITMAPS for Smar devices can be obtained through the website: (https://www.smar.com), select "Download" option in the product specific page.

The following example shows the necessary steps to integrate the IF303 on a PROFIBUS system.

View

3.5

IF303 – Operation and Maintenance Instruction Manual

These steps are valid for the entire 303 line of Smar devices:

 Copy the IF30 3 gsd file to the research directory of the PROFIBUS configuration tool, usually

called GSD;

 Copy the IF303 b itmap file to the research director y of the PROFIBUS configuration tool usually

called BMP;

 After choos ing the master, define the communication rate. Do not forget that the cou plers may

have the following fixed communication rates 45,45 kbits/s (Siemens) or 9 3,75 kbits/s (P+F) and variable comm rates up to 12 Mbit/s as instance: SK2 and SK3 from P+F, link IM157 from Siemns and Smar’s controllers with embedded couplers (DF95 or DF97);

 Add the IF303 and specify its physical bus address;  Choose the cyclic configuration via parameterization using the gsd file that depends on the

application, as detailed previously. For every AI (Analog Input) block, the IF303 provides the process variable to the master in 5 bytes value, being the first four according to float poin t data type and the fifth byte is the status that brings the measure quality of this information.

In the TOT (Totalizer) block, the user can choose the totalization value (Total) and the integration is made considering the operati on mode (Mode_Tot). It allows defining of how the totalization will be, with the following options: only positive value of the flow, only negative values of the flow, or both. In this block, the user can reset the totalization and configure the preset value through the Set_Tot parameter. The reset option is very used in batch processes;

 It allows activating the condition of watchdog, which the device goes to a fail safe condition,

when a loss of communication is detected with the master.

Using ProfibusView, AssetView for FDT from Smar or Simatic PDM configuration software from Siemens, for instance, user may configure parameters of the Input Transducer block. See Figure 3.2

How to Configure the Analog Input Block

The Analog Input block takes the input data from the Transducer block, selected by channel number, and makes it available to other function blocks at its output. T he transducer block provides the input unit of the Analog Input, and when the unit is cha nged in the transducer, the PV_SCALE unit is changed too. Optionally, a filter may be applied in the process value signal, whose time constant is PV_FTIME. Considering a step change to the input, this is the time in seconds to the PV reaches 63,2% of the final value. If the PV_FTIME value is zer o, the filter is disabled. For more details, please, see the Function Blocks Specifications.

To configure the Analog Input Block select on the main menu. Using this window, the user can configure the block mode operation, selects the channel, scales and unit for input and output value and the damping.

How to configure the Totalizer Block

The Totalizer function block obtain the input data from the T ransducer block, selected by channel number, and integrates over the time. This block is normally used to totalize flow, giving total mass or volume over a certain time, or totalize power, giving the total energy.

The Totalizer Function Block integrates a variable (e.g flo w rate or power) in function of the time to the corresponding quantity (e.g., volume, mass or distance). The rate unit of the Totalizer is providing by the transducer block. Internally, the time units are converted in rate units per second. Each rate, multiplied by the block execution time, gives the mass, volume or energy incr ement per block execution.

The TOTAL is the totalized quantity. The en gineering unit used in th e output is the UNIT_TOT. The unit of the output must be compatible with the unit of t he input provided by the transducer by the channel. Then, if the input the rate is mass flow (like Kg/s, g/min, ton/h) the unit of the output must be mass (like kg, g, ton, lb, etc.). For more details, please, see the Function Blocks Specifications.

To configure the Totalizer Block select on the main menu. Using this window, the user can configure the block mode operation, selects the channel, totalizer mode and unit for the total. The user can choose up to 3 Totalizer Blocks:

Current Trim

Figure 3.19 - Set/Preset Configuration for Totalizer Block - ProfibusView

Figure 3.20 - Set/Preset Configuration for Totalizer Block - Simatic PDM

The IF303 provides the capability of making a TRIM in the input channels, if necessar y. TRIM procedure is necessary if the indication readin g of the transducer block outp ut differs from the

actual physical output. The reason may be:

 User's current meter differs from the factory standard.  Converter had its original characterization signal shifted by over-load or by long term drift.

3.16

Configuration

User can check the calibration of the transducer output by measuring t he actual current in the input and compare it with the indication of the device (an appropriate meter must be used). If a mismatch is detected, a TRIM can be done.

TRIM can be done in two points:

Lower TRIM: Is used to TRIM the lower value of the input range. Upper TRIM: Is used to TRIM the upper value of the input value.

These two points define the linear characteristic of the output. TRIM in one point is independent from the other. There are at least two ways of doing the T RIM: using local adjustment or using a Configuration Tool (see below examples using ProfibusView). When doing the TRIM, make sure you are using an appropriate meter (with the necessary accuracy).

Via ProfibusView, AssetView for FDT or Simatic PDM

The channel number of the AI block is related to the transducer ’s terminal block number. Channel number 1,2,3 corresponds bi-univocally to the terminal block with the same number. Therefor e, all the user has to do is to select combinations: (1, 1), (2, 2), (3, 3), for (CHANNEL, TERMINAL NUMBER).

It is possible to calibrate the current inputs of the transmitter by means of parameters CAL_POINT_LO and CAL_POINT_HI.

Let’s take the lower value as an example: Supply 4 mA or the lower value to the terminal block and wait until the readout of parameter

PRIMARY_VALUE stabilizes. Write 4.00 or the lower value in parameter CAL_POINT _LO. For each value written a calibration is

performed at the desired point.

Let’s take the upper value as an example: Supply 20 mA or the upper value to the terminal block and wait until the readout of parameter PRIMARY_VALUE stabilizes. Write 20.00 or the upper value in parameter CAL _POINT_HI. For each value written a calibration is performed at the desired point.

Configuration

It is recommended, for every new calibration, to saving the existent TRIM data by means of parameter BACKUP_RESTORE, using option "Last Cal Backup".

Via Local Adjustment

The IF303 has 3 input transducers and it is provided by SMAR with default settings. T he factory setting establishes only the transducers #1 as default for local adjustment. In order to configure the others via local adjustment, user shall configure them in the display trans ducer via Configuration Tool, according specific instructions for this transducer block.

In order to enter the local adjustment mode, place the magnetic to ol in orifice “Z” until flag “MD” lights up in the display. Remove the magnetic tool from “Z” and place it in orifice “S” until the message “LOC ADJ” is displayed. The message will be displayed during approximately 5 s econds after the user has removed the magnetic tool from “S”. By placing the magnetic t ool t he user will be able to access the local adjustment tree in the monitoring mode.

Browse to parameter P_VAL (PRIMARY_VALUE). Supply 4.0mA or the lower value to the terminal block and wait until the read of the parameter

stabilizes in the display. Browse to parameter “LOWER”. After that, in order to start calibration, the user will act on the

parameter “LOWER” by placing the magnetic tool in “S” down to 4.0 mA. Let’s take the upper value:

Supply 20.0mA or the upper value to the terminal block and wait until the readout of parameter P_VAL stabilizes, and then actuate parameter UPPER up to 20.0.

TRIM mode exits via local adjustment automatically when the magnetic tool is not used during approximately 16 seconds.

Keep in mind that even when parameters LOWER or UPPER present the desired value, they must be actuated so that calibration is performed.

Limit Conditions for Calibration:

For every writing operation in the transducer blocks there is a code indication for the operation associated with the writing method. These codes appear in parameter XD_ERROR every time a calibration is performed. Code 16, for example, indicates a successfully performed operation.

Among the possibilities b y Local Adjustment, the following options can be emphasized: Mode block, Outputs monitoring, Tag visua lizati on and T uning Parameters setting.

The interface between the user is also described very detailed on the "General Installation, Operation and Maintenance Procedures Manual" Pl ease take a detailed look at this manual in the chapter related to "Programming Using Local Adjustme nt". It is significantly the resources on this transducer display, also all the 303 Series field devices from SMAR has the same methodolog y to handle with it. So, since the user has learned once, he is capable to han dle all kind of field devices from SMAR. This Local adjustment configuration is a suggestion only. The us er may choose his preferred configuration via configuration toll, simply configuring the displa y block).

The converter has two holes for magnetic switches activated by the magnetic tool located und er the identification plate. These magnetic switches are activated by one magnetic tool (see figure 3.35).

This magnetic tool enables adjustment of the most important parameters of the blocks. It also enables pre-configuration of the communication.

The jumper W1 on top of the main circuit board must be i n place for this f unction to be enab led and the converter must be fitted with the digital display for access to the loc al adjustment. Without the display the local adjustment is not possible.

NOTE

This Local adjustment configuration is a suggestion only. The user may choose his preferred configuration via Configuration Tool, simply configuring the display.

Via cyclic communication is possible to verify diagnostics from the IF303 using the Profibus Master Class 1 or even via acyclic communication via Master Class 2. The Profibus-PA dev ices provide up to 4 standard diagnoses bytes via Physcial Block (see figure 3.43 and 3.44) and when the most significant bit of the fourth Byte is "1", the diagnose will extend the information in more 6 bytes. These Diagnosis bytes can also be monitored via cyclic tools.

IF303 – Operation and Maintenance Instruction Manual

If the FIX flag is active on LCD, the IF303 is configured to "Profile Specific". When in "Manufacturer Specific", the Identifier Number is 0x0896. Once the Identifier_Number_Selector is changed from "Profile S pecific" to "Manufacturer Specific" or vice-versa, you must wait 5 seconds while it is saved and the turn off the IF303 and then the identifier is updated in the level of communication. If the equipment is in "Profile Specific" and using the GSD file Identifier Number equals 0x0896, the acyclic communication will work well with tools based on EDDL, FDT/DTM, but no cyclic communication with the Profibus-DP master will get success.

MAINTENANCE PROCEDURES

NOTE

Equipment installed in hazardous atmospheres must be inspected in compliance with the IEC60079-17 standard.

SMAR IF303 Current to PROFIBUS PA Converters are extensively tested and inspected before

delivery to the end user. Nevertheless, during their design and development, consideration was given to the possibility of repairs by the end user, if necessary.

In general, it is recommended that the end user do not try to repair printed circuit boards. Instead, he should have spare circuit boards, which may be ordered from SMAR whenever necessary.

Converter PROFIBUS Connections

Check wiring polarity and continuity.

Power Supply

Check power supply output. The voltage at the IF303 terminals must be between 9 and 32 Vdc.

Electronic Circuit Failure

Check the boards for defect by replacing them with spare ones.

Network Connections

Check the network connections: devices, power supply, couplers, links, and terminators.

Transmitter Configuration

Check configuration of communication parameters of converter.

Network Configuration

Check communication configuration of the network.

Electronic Circuit Failure

Try to replace the converter circuit with spare parts.

Input Terminals Connection

Check wiring polarity and continuity.

Conventional Transmitter

Verify if the conventional transmitter is working properly or if it has the necessary voltage. Remember that IF303 has a 100 Ohms plus 0.8 V input impedance.

Calibration

Check calibration of IF303 and the conventional transmitters.

IF303 – Operation and Maintenance Instruction Manual

If the problem is not presented in the table above follow the Note below:

The Factory Init should be tried as a last option to recover the equipment control when the equipment presents some problem related to the function blocks or the communication. This operation must only be

carried out by authorized technical personnel and with the process offline, since the equip ment will be configured with standard and factory data.

This procedure resets all the configurations run on the equipment, after which a partial download should be performed. With exception to the equipment physical address and the gsd identifier number selector parameter. After doing this, all configurations must be remade according to their applications.

To run the factory Init, use two magnetic screwdrivers. Remove the screw on the equipment that fixes the identification tag on the carcass top to access the orifices bearing the letters “S” and “Z”.

The operations to follow are:

1) Turn off the equipment; insert the magnetic tools in each orifice (S and Z). Leave them in the orifices;

2) Power the equipment;

3) As soon as Factory Init is shown on the display, take off the tools and wait for the "5" symbol on the right upper corner of the display to unlit, thus indicating the end of the operation.

This operation has factory configuration that eliminates possible problems with the functional blocks or the transmitter communication.

Disassembly Procedure

Refer to Figure 4.1 - IF303 Exploded View Make sure to disconnect power supply before disassembling the converter.

To remove the circuit boards (5 and 7) and display (4), first loose the cover locking (8) on the side not marked “Field Terminals”, then unscrew the cover (1).

The boards have CMOS components, which may be damaged by electrostatic discharges. Observe correct procedures for handling CMOS components. It is also recommended to store the circuit boards in electrostatic-proof cases.

Loose the two screws (3) that anchor the display and the main circuit board. Gently pull out the display, and then the main board (5). To remove the input board (7), first unscrew the two screws (6) that anchors it to the housing (9), and gently pull out the board.

Reassembly Procedure

 Put input board (7) into housing (9).

 Anchors input board with their screws (6).

 Put main board (5) into the housing, ensuring all inter connecting pins are connected.

 Put display (4) into the housing, observing the four mounting positions. "▲" should point in the

direction desired as UP.

 Anchors main board and display with their screws (3).

 Fit the cover (1) and lock it using the locking screw (8).

NOTE

WARNING

4.2

Boards Interchangeability

Main and input boards are supposed to stay together, because calibration data from input board circuit is stored in EEPROM of the main board.

If, for some reason, you separate the input and the main boards, you must do a trim to guarantee precision of the inputs. With mismatched boards, the factory trim will not be as good as it was.
