Setting

Use the "HART Settings" dialog to set the master properties.

After the corresponding channel selection, the following parameters can be changed.

• PreambleLength  Length of the master preamble. If this is set to "Automatic Assign", the master automatically communicates with the minimum supported length of the connected HART slave.
• MasterMode  Selection of primary or secondary master mode.
• DefaultPollingAddress  A slave must be polled via Cmd0 in order to be able to form a unique address via the obtained information. Sets the address through which Cmd0 is polled (possible range: 0..63).
• PollingTime  If a cyclic HART communication is enabled, this value specifies the cycle time.
• MaxRetrys  If a HART request was not answered correctly, this indicates the maximum number of repeat cycles.

The settings have to be confirmed with the button "Write to Actual Channel..." before they become active and are saved, if required. 

Use "Set to Default..." to switch back to the default values.

The button "Scan Polling Address..." enables the connected HART device to be scanned and therefore the polling address that was used to be found. The scanning range is 0 to 63. The scan is aborted once a device has responded. The address that was found can be included in the project.
