Configuring a HART sensor in Siemens TIA Portal involves setting up both the HART module and the HART communication itself. Here's a general breakdown:

1. Configuring the HART Module:

• Open TIA Portal and create a project.
• Add a compatible CPU and the HART module.
• In the Device View, navigate to the HART module and open its properties.
• Enable diagnostics and set measurement parameters for the channel connected to the HART sensor.
• Enable the HART function for that channel.

2. Configuring HART Communication:

• Navigate to "HART variables settings" within the HART module properties.
• This might involve using SIMATIC PDM, a separate tool included with TIA Portal.
• Consult the specific HART sensor's manual to identify the desired process variables.
• Within the HART configuration, choose the relevant process variables to be read from the sensor.
