Commubox FXA291 CDI/USB, intrinsically safe interface for intelligent level transmitters, converts HART protocol signals into USB signals

Advantages

On-site commissioning of Endress+Hauser devices
Simple connection of field devices to a computer USB port via the CDI interface
The Commubox is powered via the USB interface
The field device can also be powered via the CDI interface
Connects intrinsically safe and non-intrinsically safe field devices
Suitable for Endress+Hauser operating software such as FieldCare
CDI/USB drivers can be installed on Windows 2000, Windows XP and Windows 7 (x32+x64)

Field of application

The Commubox FXA291 is an intrinsically safe CDI interface (Endress+Hauser common data interface) for level transmitters that converts signals via the USB port. Field devices communicate with the computer via the CDI, the ToF adapter FXA291 or an adapter cable.

The Commubox FXA291 connects Endress+Hauser field devices to the USB port of a user computer or laptop via the CDI interface (Endress+Hauser common data interface). With Endress+Hauser operating software such as the plant-specific asset management system FieldCare, users can operate and service field devices remotely. USB low-power devices can be powered via the computer USB port.

Municipal Wastewater Treatment

Municipal Wastewater Treatment · Gateways and modems — Application Case

Project Background

The project covers the inlet, biological and outlet stages of a municipal plant. The work centres on Gateways and modems and the core task is converting field data into remote transmission channels.

Operating Challenges

The medium and duty are characterised by high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. So Gateways and modems cannot be specified generically — it calls for configured by protocol, tag count and carrier network conditions.

Solution

The Ainstru engineering team worked through the system components range: supplying as a full cabinet and signal-chain configuration. The configuration involves configured by protocol, tag count and carrier network conditions, with these requirements in view: stable compliance with Grade 1A discharge limits and online data reporting.

Results

Since start-up the system has run steadily; the practical result is remote sites can report back, making unattended operation possible.

Food & Beverage

Food & Beverage · Gateways and modems — Application Case

Project Overview

The site is dosing, pasteurising, filling and CIP stages. The customer wanted Gateways and modems properly configured on the existing plant, with the aim of converting field data into remote transmission channels.

Technical Challenges

What actually causes trouble is syrups, dairy and beverages that scale easily, under strict hygienic requirements, and frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. All of this means the Gateways and modems configuration has to involve configured by protocol, tag count and carrier network conditions.

Configuration

Supply and installation were organised through the system components range: supplying as a full cabinet and signal-chain configuration. On site this meant configured by protocol, tag count and carrier network conditions, checked line by line against: food-safety and hygienic design per 3-A / EHEDG.

Performance

After commissioning the outcome is remote sites can report back, making unattended operation possible, and the readings are now used for process tuning.

Chemical & Pharmaceutical

Chemical & Pharmaceutical · Gateways and modems — Application Case

Site Conditions

This is a Chemical & Pharmaceutical customer whose plant is at reactors, metering vessels and finished-product tanks. The main task was converting field data into remote transmission channels.

The Problem

The difficulty lies in highly corrosive media with solvents and crystallisation, partly in explosive atmospheres; at the same time corrosion plus Ex protection shortens instrument life and makes downtime costly. Specification therefore means configured by protocol, tag count and carrier network conditions.

What We Did

We took a system components range approach — supplying as a full cabinet and signal-chain configuration. Delivery was built around configured by protocol, tag count and carrier network conditions, with point-by-point checks on: Ex certification and GMP traceability of records.

Operating Outcome

In service the system performs as intended — remote sites can report back, making unattended operation possible, with routine maintenance falling noticeably.

Power & Energy

Power & Energy · Gateways and modems — Application Case

Application Context

boiler feedwater, turbine condensate and FGD/DeNOx systems is a typical Power & Energy duty. The project started from Gateways and modems, focusing on converting field data into remote transmission channels.

Process Constraints

drift under high temperature and pressure, with very costly unplanned outages, and high temperature and pressure with both steam and saline water only amplify it. The Gateways and modems specification must therefore cover configured by protocol, tag count and carrier network conditions.

Delivery Approach

Delivery was handled as the system components range — supplying as a full cabinet and signal-chain configuration. Execution centred on configured by protocol, tag count and carrier network conditions, together with compliance with power-industry codes and unit availability targets.

Field Results

Operation shows the benefit clearly — remote sites can report back, making unattended operation possible, with confidence in this measuring point improving markedly.
