   • Module: Select pre-configured values from Device module

3. Connection Name Setting: Specify a unique connection name

   • No duplicates allowed

4. Communication Settings:

   • Default Mode: Direct input of device-specific detailed settings

   • Module Mode: Select pre-configured values

Precautions

• Connection names must be unique within the project

• Verify that IP addresses and ports are correct

• Ensure the target device supports the selected protocol
