Topics

  • What is intelligent device management?
  • Integrated device management
  • Why do I need a handheld field communicator?

– With fieldbus, I can do everything remotely from the control room, right?

  • Handheld and workstation, are they the same?

Calibrate ANSI/ISA–S51.1–1979 (R1993)

Calibrate: To ascertain outputs of a device corresponding to a series of values of the quantity which the device is to measure, receive,

  • r transmit. Data so obtained are used to:

1) determine the locations at which scale graduations are to be placed; 2) adjust the output, to bring it to the desired value, within a specified tolerance; 3) ascertain the error by comparing the device

  • utput reading against a standard.

Calibration

  • What does it mean?

1. Determine the locations at which scale graduations are to be placed;

– Set the 4 mA and 20 mA points (range) – Scaling/ranging can be done remotely without applying input – Scale/range not applicable to most fieldbus transmitters

2. Adjust the output, to bring it to the desired value, within a specified tolerance;

– Trim the output current – Need to connect a multimeter – Not applicable to fieldbus

3. Ascertain the error by comparing the device output reading against a standard.

– Trim the sensor reading – Need to apply input (e.g. equalize and vent manifold to zero) – Is applicable to fieldbus

Calibration for Fieldbus

  • Sensor Trim

– If measurement reading is wrong it must be corrected

  • E.g. correct for mounting position

– From transducer block – Need to apply input

  • Done in the field
  • Configure Range/Scale

Setting

–Zero and Span

  • In PID block (valve or

controller)

  • In AI block for inferential

measurements such as DP flow and DP level

  • Some transmitters may need

range to operate

  • Cancel wet-leg etc.

–Set the portion (range/scale) between sensor limits which is of interest for application –In function block –Just setting a value

  • Done remotely from control room

Calibration Trim

  • Methods

simplify complex tasks

  • Ensure

correct procedure

  • Eliminates

mistakes

Field Calibration Trim Tools

  • Field Communicator

– Plus calibrator – Clipboard for notes

  • Documenting

calibrator

– With Fieldbus interface – Mainly pressure and temperature Reduce Paper Work

Why do I need a handheld field communicator?

  • Field tasks

– Sensor trim

  • Turn manifold

– Cancel wet-leg

  • Verify empty

– Valve stroking

  • See it move

– Repair

  • If it indeed failed
  • Laptop/tablet

– Heavy – Moving parts – Usually not rugged – Not hazardous area certified – Limited battery life

Are Handhelds and Device Management Software The Same?

  • Information content & structure

– Same, because determined by the device manufacturer, not the system/handheld

  • Look & feel

– Slightly different, because dependent on the platform

  • Screen size, color, keyboard, mouse...
  • Features

– Different

  • Device management software is permanently connected
  • Device management software has a database

– Audit trail, scheduling, persistent data storage, manuals, other documents etc.

Conclusion

  • You don’t have to go to the field as often

– Diagnostics and configuration done remotely

  • You still need to go to the field sometimes
  • Working in the field is easier than in the past
  • Specialized tools and solutions for fieldbus are

available

  • Fieldbus is not difficult
