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.

NOTE

In case of using Simatic PDM as the configuration and parameterization tool, Smar

recommends that the user does not apply the option "Download to Device". This function

can improperly configure the field device. Smar recommends that user make the use of

the option "Download to PG / PC" and then selecting the Device Menu, use the menus of

the transducer, function and display blocks acting specifically, according to each menu

and method for reading and writing.

This product is protected by US patent number 5,706,007.

NOTE

This Manual is compatible with version 3.XX, where 3 denotes software version and XX software release. The

indication 3.XX means that this manual is compatible with any release of software version 3.

Waiver of responsibility

The contents of this manual abides by the hardware and software used on the current equipmen

version. Eventually there may occur divergencies between this manual and the equipment. The

information from this document are periodically reviewed and the necessary or identified corrections

will be included in the following editions. Suggestions for their improvement are welcome.

Warning

For more objectivity and clarity, this manual does not contain all the detailed information on the

product and, in addition, it does not cover every possible mounting, operation or maintenance

cases.

Before installing and utilizing the equipment, check if the model of the acquired equipment complies

with the technical requirements for the application. This checking is the user’s responsibility.

If the user needs more information, or on the event of specific problems not specified or treated in

this manual, the information should be sought from Smar. Furthermore, the user recognizes that the

contents of this manual by no means modify past or present agreements, confirmation or judicial

relationship, in whole or in part.

All of Smar’s obligation result from the purchasing agreement signed between the parties, which

includes the complete and sole valid warranty term. Contractual clauses related to the warranty are

not limited nor extended by virtue of the technical information contained in this manual.

Only qualified personnel are allowed to participate in the activities of mounting, electrical connection,

startup and maintenance of the equipment. Qualified personnel are understood to be the persons

familiar with the mounting, electrical connection, startup and operation of the equipment or othe

similar apparatus that are technically fit for their work. Smar provides specific training to instruct and

qualify such professionals. However, each country must comply with the local safety procedures,

legal provisions and regulations for the mounting and operation of electrical installations, as well as

with the laws and regulations on classified areas, such as intrinsic safety, explosion proof, increased

safety and instrumented safety systems, among others.

The user is responsible for the incorrect or inadequate handling of equipments run with pneumati

or hydraulic pressure or, still, subject to corrosive, aggressive or combustible products, since thei

utilization may cause severe bodily harm and/or material damages.

The field equipment referred to in this manual, when acquired for classified or hazardous areas, has

its certification void when having its parts replaced or interchanged without functional and approval

tests by Smar or any of Smar authorized dealers, which are the competent companies for certifying

that the equipment in its entirety meets the applicable standards and regulations. The same is true

when converting the equipment of a communication protocol to another. In this case, it is necessar

sending the equipment to Smar or any of its authorized dealer. Moreover, the certificates are

different and the user is responsible for their correct use.

Always respect the instructions provided in the Manual. Smar is not responsible for any losses

and/or damages resulting from the inadequate use of its equipments. It is the user’s responsibility to

know and apply the safety practices in his country.
