CC-TDOB11 Honeywell Input module Brand new

Device

variable

classification

Provides master applications with a simple mechanism to determine the number

and type of process related variables (pressure, temperature, etc.) within a device.

Extended

device status

Provides additional device status alerts such as 'Device Needs Maintenance.'

Device

variable

status

Enables field devices to self-validate and report on the quality of the data in the

command response (good, poor, bad, fixed).

Long Tag New Long Tag with international (ISO Latin 1) characters allows consistent

implementation of the longer tag names required by many industry users. The

specifications currently reflect the length of this tag to be 32 characters.

Configuration

change

counter

Improved mechanism for master applications to determine that a field device

configuration has been changed. Protects integrity of plant configuration

databases.

Device

Families

Establishes standard commands and status indicators for devices based on the

type of process measurement. Initial Device Families include Temperature and PID

Control.

Transducer

Trim

Commands

New Common Practice commands for performing transducer trim (calibration)

operations.

Sub-Devices Simple mechanism using Common Practice Commands to support 'HART device

within a HART device' functionality. Potential uses include flow computers and

multi-channel temperature devices.

Block Data

Transfer

An updated mechanism to support the movement of large blocks of data, such as

device configuration information, between masters and field devices.

Catch Device

Variable

Simple mechanism to support the sharing of process data between field devices on

the same HART network. Allows a listening field device to capture process data

from another field device to be used in calculations such as tank gauging, flow

computers or PID control functions.

Write Device

Variable

New Command to support forcing the digital value for any Device Variable to a

specific value to aid in commissioning and troubleshooting.

Lock Device New Commands to allow a master application to lock the 'local' front panel of a field

device while performing remote configuration functions.

Squawk and

Find Device

New commands to support commissioning and troubleshooting of HART devices in

multi-drop and multi-pair cable installations.
