Introduction

The HI302 is a hardware component integral to System 302 which main function is to interface

HART devices to Foundation Fieldbus Systems, allowing the user to perform maintenance,

calibration, sensor status monitoring, device status, among others information.

See below some HI302 features:

•Integral Part of System 302;

•Tight integration with different system manufactures due to the use of standard protocols such

as Foundation Fieldbus;

•8 HART master channels;

•Optional Analog Conversion (4-20 mA / Foundation Fieldbus – HI302-I and Foundation Fieldbus

/ 4-20 mA – HI302-O);

•Totally integrated to Asset View;

•Easy to operate due to a uniform system and tools;

•Not-multiplexed and independent HART channels;

•HART Configuration Commands located into the module and possibility to send HART

messages through parameters and bypass;

•Suitable for Asset Management System;

•Complete configuration of Smar devices embedded in HI302 module, thus no additional

configuration is required.

General Vision

This user manual contains instructions on how to configure and install the HI302.

General Characteristics

Among the main characteristics, the following may be mentioned:

•The HI302 supports up to eight peer-to-peer HART devices or 32 HART devices in the

multidrop mode (4 devices per channel);

•8 HART Master communication ports that can be configured as Primary or Secondary;

•1 Foundation Fieldbus H1 Channel;

•Feeding via backplane (5Vdc @500 mA);

•Device Feeding via outside source;

•Input circuits 4-20 mA on HI302 – I (current conversion to Fieldbus);

•Output circuits 4-20 mA on HI302 – O (Fieldbus conversion to current);

There are three models for the HI302, according to the analog conversion needs:

•HI302 – N: only HART communication;

•HI302 – I : HART communication and conversion of eight 4-2- mA analog inputs to FF;

•HI302 – O: HART communication and FF conversion to eight 4-20 mA analog outputs;

Function Blocks

Several blocks were implemented to give the module the required functionality.

HART Transducer Blocks

HCFG (HART Configuration) – Concentrates general configuration parameters for

module working, in addition to parameters on HART Communication performance and

diagnostic.

HIRT (HART Identification and Real Time data) – This block contains the main

parameters, i.e., the most commonly used, besides dynamic variables. All parameters

related to universal commands and some main “Common Practice” commands are found

here. There should be one HIRT block for each HART device installed, up to 32 blocks. In

normal operation, the HIRT block parameters show the HART device variables, since

there are mechanisms to keep the HI302 database updated. See the Appendix A or the

Function Blocks handbook for details.

HVT (HART Variable Template) – This block is a large collection of variables for general

use arranged in arrays. It is now possible to access any HART instrument parameter. To

this effect, the module should get a configuration (HCD and HWPC blocks) to define the

specific instrument one wants to access, and how these commands will relate to each

parameter on the block. There is just one HVT block that should be shared among the

devices when accessing them through the HART_TAG. This configuration is already

configured in the Smar device’s memory.

1.3

HCD (HART Command Definition) – It contains the HART command description for each

device type or version. This description stores information needed by the module to

communicate and the data read on the HIRT or HTV blocks. The HCD blocks defining the

universal and the common practice commands, as well as all commands specific to Smar

instruments, are already stored in the equipment’s memory and do not require any

configuration from the user. See the Appendix B for details.

HWPC (HART Writeable Parameter Command Correlation) – This block stores

information about all parameters to be written on the instrument and mapped on the HVT

block.

See table with detailed definitions on the Appendix A blocks.

In order to support the analog circuits on HI302-I and HI302-O modules, use the MAI or

MAO blocks, respectively, to convert the analog 4-20 mA standard to FF or FF to 4-20

mA. Inquire about our availability of AI or AO blocks.

MAI – Multiple Analog Input

The MAI block makes available to the fieldbus network 8 variables of the I/O subsystem

through 8 output parameters, namely, OUT_1 to OUT_8. These parameters correspond to

the current value, in percentage, on the 8 analog inputs.

MAO – Multiple Analog Output

The MAO block makes available to the I/O Subsystem 8 input parameters, IN_1 to IN_8.

These parameters correspond to the current value on the 8 analog outputs.
