5 Appendix

Introduction

This appendix contains descriptions of the HART commands
available through the HART universal, common practice and
device specific command sets.
Device-specific command details such as data bytes and
response codes are described in the AWT210 HART field device
specification (COM/AWT210/HART-FDS-EN)

Supported HART commands

The following HART Commands are supported on the AWT210.

Universal HART commands

Command Description
3 Read Dynamic Variables And Loop Current
14 Read Primary Variable Transducer Information
Table 1 Universal HART commands

Common practice HART commands

Command Description
34 Write PV Damping Value
35 Write PV Range Values
36 Set PV Upper Range Value
37 Set PV Lower Range Value
40 Enter/Exit Fixed Current Mode
41 Perform Self-Test
42 Perform Device Reset
44 Write PV Units
45 Trim Loop Current Zero
46 Trim Loop Current Gain
48 Read Additional Device Status
59 Write Number of Response Preambles
71 Lock Device
76 Read Lock Device State
*Requires HART login (Command 168) to Advanced level or higher if HART login is enabled
via Configuration -> Advanced-> Device Setup -> Security -> HART Login -> Enabled

AWT does not support device variables, only dynamic variables. Hence,
Command 9 returns a response code of 14 (Dynamic Variables returned for
Device Variables) as required by the HART specification. However, this return
value is seen as an error by Simatic PDC software. This response code may
be turned off in the device by enabling PDM compatibility at the following
menu: Device Setup > PDM Compatibility > Enable.

HART commands that write to the device can be protected with access
control. This is similar to the access control within the device that has
Read Only, Calibrate, Advanced and Service levels.
Access control for HART can be enabled at the following menu:
Device Setup > Security Setup > HART Logging > Password Protected.
If this option is enabled, the user will have to log in with the appropriate
access level password before sending write commands to the device. Please
see details of command 168 in the HART Field Device Specification
document for AWT210.
