	Control router - IMPORTANT From: Wu Lili 吴丽丽 <wulili@longteng-co-ltd.gd.cn>
I’m pleased to say we have been selected for another Sun Haotian project, a simple data router for smart grids. Mr. Sun was never interested in civic infrastructure before to my knowledge, so I really wonder what he’s planning. I may ask around. My uncle’s had dinner with him once or twice. Lili Wu

We can do it. Note: These XBus inputs are blocking, so we will need to connect all inputs so they can be read at once (simultaneously). Jie.

This is just the tip of the iceberg. Mr. Sun is apparently pulling in a lot of resources and groups to create various subsystems for something. Nobody knows what it is other than that it’s going to be very big and potentially very lucrative for the firms involved. We’re on a path to further our good relationship with his group and eventually become trusted partners, so let’s continue to do our best work here. Lili Wu

Description

meter-in and meter-out are XBus inputs and outputs that connect this node to a building’s “smart grid” power meter. lower-in and lower-out are XBus inputs and outputs that connect this node to a node with a lower ID number. higher-in and higher-out are XBus inputs and outputs that connect this node to a node with a higher ID number. The first value in a data packet is the ID number of the destination, and indicates how the packet should be handled: ID < meter ID retransmit data packet to the lower node ID = meter ID retransmit data packet to the meter ID > meter ID retransmit data packet to the higher node The local ID number of the node is stored in a secure identity chip that can be read as an XBus input. The second value in a data packet is the length of the rest of the data packet.
