The project tags were created to simplify the configuration of the module. Some of the
tags defined in the sample project utilize the user defined data types described in the
previous section.
The user defined tags from the controller scope should be copied to your project before
the tags contained in the individual program sections. Open the controller tags on the
sample project and select the edit tags mode. Grab the tags you want to copy by using
the left mouse button and dragging. See figure below.
Description
Defines the structure of the HART data returned by the
module when the module specific command, Get
Device Information, is sent to module.
This data type defines the structure for tags used to
send messages to and from the module using the paging
1
scheme.
Defines the structure for tags used to send HART pass
through messages to and from the module.
Defines the data structure for HART packet 0. HART
packet zero contains device information for the
connected HART device.
Defines the data structure for HART packet 1. HART
packet 1 is used to display the four dynamic variables
for the selected HART device.
Defines the data structure for HART packet 2. HART
packet 2 is used to display the slot variables for the
connected HART device.
Defines the data structure for HART packet 3. HART
packet 3 displays the ASCII message for the connected
1
HART device.
Defines the data structure for HART packet 4. HART
packet 4 contains the extended status for the connected
1
HART device.
