Both DPX2 and DX sensor packages can be daisy chained. The PXE can indicate each sensor or actuator's position by showing the sensor port where the environmental sensor package is connected as well as its sequence in a sensor daisy chain.
For example, if a DPX environmental sensor package is connected to the SENSOR port numbered 1, its Position column shows "Port 1."
Note: For the PXE devices with only one SENSOR port, it always shows 'Port 1.'
For example, if a sensor or actuator is located on the second sensor package in the sensor chain connected to the SENSOR port 1, its Position column shows "Port 1, Chain Position 2."
