When the H1 fieldbus cards are plugged into the I/O carrier, the fieldbus devices are connected to the H1 cards' terminal block, the Device Descriptions loaded, the H1 card automatically detects the fieldbus devices, recognizes the device types, and makes this information available to the DeltaV system.
The DeltaV system autosenses the H1 cards.
As with other cards and devices, you can add H1 cards and fieldbus devices as placeholders in the DeltaV Explorer. A placeholder device matches the manufacturer and model of a device that has not been connected and holds the device tag and address. When you are ready to commission the device, move it to Standby, and drag the device to the placeholder. The device connects to the segment with the device tag and address that was specified for the placeholder.
