For example, if a DPX sensor package is connected to the SENSOR
port numbered 1, its Position column only shows "Port 1" no matter a
DPX3-ENVHUB4 sensor hub is used or not.
Note: For the PX devices with only one SENSOR port, it always
shows "Port 1."
DPX2, DPX3 and DX sensor position information:
The PX displays the sensor package's position in the chain in
addition to the sensor port number for DPX2, DPX3 and DX sensor
packages.
For example:

If a DPX2, DPX3 or DX sensor or actuator is located on the
second sensor package in the sensor chain directly connected to
the SENSOR port 1, its Position column shows "Port 1, Chain
Position 2."

If this sensor chain is connected to the SENSOR port 1 via the
DPX3-ENVHUB4 sensor hub, this sensor's or actuator's Position
column becomes "Port 1, Chain Position 1, Hub Port x, Chain
Position 2," where x is the hub's port to which this sensor or
actuator is physically connected.
Identifying Sensor or Actuator Channels
A sensor package may have multiple contact closure (CC) or dry contact
(DC) channels, such as DX-D2C6 or DX-PD2C5.
When the PX initially detects and automatically manages a sensor
package with multiple channels, all channels are assigned with ID
numbers in sequence.
If you manually manage these channels by selecting "Automatically
assign a sensor number," the PX assigns ID numbers randomly because
this option assumes that users do not care about the sequence. In this
case, see the Channel column to identify each channel correctly. For
example, CC1 or DC1 is Channel 1, CC2 or DC2 is Channel 2, and so
on.
