For the LN-SVSENx-0, the subnetwork bus extends the LON trunk to the LN-SVSENx-0 sensor to provide network access for maintenance and troubleshooting.
The LN-PRG6x0-12 controllers use the subnetwork bus to support the LN-IOE4x0-0 Series Modules through 2-wire shielded cable.
All LN-VAVCF-12 controllers also use the subnetwork bus to support up to four LN-SVSENx-0 sensors using standard structural cabling.
For an overview depiction of a subnetwork including LN Communicating Sensors, see Figure 4.
