Electronic Device Desc ript ionLanguage (EDDL)

Key to easy, simple upgrades New field devices are easily added

No host software revisions

No custom drivers or interfaces Software drivers can be automatically up-

loaded to host systems

Fosters product innovation and

development

Methods Simpl i fy Maintenanceand Reduce Errors

Zero ThisTransmitter!

1. Set MODE_BLK.TARGET to OOS

2. Apply zero pressure to the sensor and allow the to

reading stabilize3. Set value CAL_POINT_LO to 0

4. Set SENSOR_CAL_DATE to the current date.

5. Set SENSOR_CAL_WHO to the person responsible

for the calibration.

6. Set SENSOR _CAL_LOC to the calibration location.

7. Set SENSOR_CAL_METHOD to User Trim

8. Set MODE_BLK.TARGET to AUTO

Existing DD Capability - Temperature Example

Device data is described

by VARIABLE, RECORD

and ARRAY constructs in

the DD file.

The host typically displaysthe device data as a list.
