产品详情资料
在点1(搜索树的根),新一轮开始。这里检测到碰撞,
即至少两个站有数据要发送。总线主机转移到树中的点2
使用功能代码13和14搜索要发送
小包裹只有连接到点2以下的子树的通信接口可以应答。
现在,没有收到应答,总线主控器转移到点3。同样,没有答案
并且总线主控器转移到点4。在这里,检测到另一个碰撞
通信接口转移到点5,在那里只接收到一个应答。只接收到单个应答(一个两字节的从帧)。这两个字节包含
功能代码和地址/控制字段。从属框架
构成总线主控器必须在可能时发送的主帧,以便为
应答的通信接口。At point 1 (the root of the search tree) the new round is begun. Here a collision is detected,
that is at least two stations have data to send. The bus master transfers to point 2 in the tree and
uses function codes 13 and 14 to search for a communication interface which wants to send a
packet. Only the communication interfaces attached to the sub-tree below point 2 may answer.
Now, no answer is received, and the bus master transfers to point 3. Again, no answer is
received, and the bus master transfers to point 4. Here, another collision is detected, and the
communication interface transfers to point 5, where only a single answer is received.Eventually, only a single answer is received (a two byte slave frame). These two bytes contain a
function code and an address/control field, exactly like a master frame. The slave frame
constitutes a master frame which the bus master must send when possible in order to serve the
communication interface that answered.
