Important Points About Constructing a PLC Link

There is only one master station in an RS-485 network. If the node designated as a master station has several
serial ports, the node can not be designated as a master station in another RS-485 network, but can be
designated as a slave station in another RS-485 network. In the figure below, C1 on the node AH-01 is
designated as a master station in network #1, and TR1 on the node AH-01 is designated as a slave station in
network #2. Besides, C1 on AH-01 and TR2 on AH-01 are connected to network #1. The station addresses
assigned to these two ports are different. As a result, TR2 is allowed to be designated as a slaved station in
network #1.
