Excuse me, how to connect and network RS485 bus and POWERBUS carrier bus?

Rs485: polling mode 4-wire connection, chain topology; Uses: industrial control field, sensors, etc.

Can: support preemption, 4-wire connection and chain topology; Uses: originated in the automobile industry, and now spread to the industrial field;

Powerbus: nonpolar wiring, arbitrary topology, two-wire communication can provide high power load capacity at the same time. Uses: It has replaced four-wire communication in fire fighting, construction, industrial control and other fields, and has broad application prospects.
