1、Forwarding rules, trunking can forward data in both directions between two NETIDs。
2、In trunk mode, ADDH/ADDL is no longer used as a module address and is forwarded as a NETID pair.
As shown in the figure：
①First-level relay
"Node 1" NETID is 08.
"Node 2" NETID is 33.
The ADDH\ADDL of relay 1 are 08 and 33 respectively.
So the signal sent by node 1 (08) can be forwarded to node 2 (33)
At the same time, the addresses of node 1 and node 2 are the same, so the data sent by node 1 can be received
by node 2.
②Secondary relay
The ADDH\ADDL of relay 2 are 33 and 05 respectively.
So relay 2 can forward relay 1's data to network NETID: 05.
Therefore, node 3 and node 4 can receive the data of node 1. Node 4 outputs data normally, and node 3 and node
1 have different addresses, so no data is output.
③Two-way relay
As shown in the configuration: the data sent by node 1 can be received by nodes 2 and 4, and the data sent by
