Challenge

How do we get access to our legacy and make the most

of it

HART installed base >30 million

What does bring us now and for the future

Process values

Status

Quality

Can we use existing infrastructures

Quality

Commonly used

PB DP >38 million

PB PA >6 million

Uniformity by NE43

First attempt to put information into the current signal, hence given some idea on the status of the measurement Warning

Even brief dips/overshoots in the standardized current signal could be wrongly interpreted as a failure signal. The failure should be present for at least 4 seconds or a minimum of 2 signal scanning cycles.

Monitor your infrastructure

Awareness of applicability

How can you get access

NOT just values

BUT Health, Quality values

How do you disclose this

Do we meet our challenge?

What relevant information is available from a HART or PROFIBUS device?

What is relevant depends on the application Operator : Process values and (condensed) Status

Training, education

Maintenance : Detailed (consistent) diagnostics and events

Training, education

20

Do we meet our challenge?

What can we use to implement HART instruments with Profibus?

Remote IO

Support of HART transparent channels. Availability of certified Communication DTM or Device Driver If required meeting HART 6 specifications (e.g. 32 characters tag, device status for every HART values [PV, SV, TV, QV].

PROFIBUS DP/PA Coupler

Hook up some 4 HART instruments to DP or PA

21

Do we meet our challenge?

Can we use the existing infrastructure

Very likely, there are instruments to help you find out

Usually setting up a worst case would give you enough information (e. g. the longest run) There modules to help you improve your impedance

22

Do we meet our challenge?

How to monitor the health status of your HART and PROFIBUS devices?

For the control system it will probably to costly to implement for each instrument the diagnostics available By applying an Intelligent PROFIBUS Access Point in parallel (bypass) to Process Automation System which is able to monitor Health Status of connected HART (pass‐through) and PROFIBUS devices according to NAMUR NE107
