当主设备将从设备联机时,会发生以下顺序:
1.主机发送诊断状态读取(SRD)。
2.从设备用其诊断状态数据(DL)响应。
3.如果诊断数据中的所有内容都正常,则主机发送
参数化数据到从属(SRD)。
4.从机响应ACK。
5.主机发送配置检查数据包,参见ProfiBus规范。
6.从机应答ACK。
7.主机发送诊断状态读取(SRD)。
8.从机用其诊断状态数据(DL)回复。如果到目前为止还有什么问题,奴隶在回复中会这样说,而主人会回到开头,下次扫描奴隶时会尝试将其联机。否则,主设备和从设备之间开始循环数据传输。在放置
卡在线。有关网络参数是什么以及如何设置这些参数的信息,请参阅第3.6节“网络参数”。
产品英文详情资料:
The following sequence takes place when a master puts a slave online:
1. The master sends a diagnostic status read (SRD).
2. The slave responds with its diagnostic status data (DL).
3. The master, if everything in the diagnostic data is OK, sends
parameterization data to the slave (SRD).
4. The slave responds with an ACK.
5. The master sends a configuration check data packet, see the ProfiBus Specification.
6. The slave replies with an ACK.
7. The master sends a diagnostic status read (SRD).
8. The slave replies with its diagnostic status data (DL). If there are any problems with anything up to this point, the slave says so now in its reply and the master goes back to the beginning and tries to bring the slave online the next time it scans it. Otherwise, cyclic data transfer begins between the master and the slave.Ensure that the network parameters have been configured before putting the
card online. Refer to section 3.6, Network Parameters for information on what the network parameters are and how to set them.
