RELIANCE WR-D4008模块卡件驱动器
如果出现错误，请检查从设备是否连接到PROFIBUS，并且是否支持此服务。LiveList使用此功能查看哪些设备连接到PROFIBUS。图23。LiveList检查一次仅连接一个地址为126的从设备。如果机框中有几个新的PA设备都具有默认地址126，则将它们一个接一个地连接到PROFIBUS，并在连接下一个设备之前更改地址。这些设备与类型信息一起列出，说明它是根据PROFIBUS上的当前节点地址排序的主设备还是从设备。通过激活刷新计时器，可以自动更新实时列表。CycleTime使用此功能读取运行PROFIBUS的当前测量周期时间。图24。CycleTime循环时间的值以µsec表示。通过激活刷新计时器，可以自动更新循环时间。显示连接到PROFIBUS的所有设备、主设备和从设备，无论其是否配置和数据交换。
In the case of an error please check that the slave is connected to the PROFIBUS
and that it supports this service.
LiveList
Use this function to see which devices are connected to the PROFIBUS.
Figure 23. LiveList
Check that only one slave with address 126 is connected at a time. If you have
several new PA devices from the shelf all with the default address 126, then
connect them one after the other to the PROFIBUS and change the address before
connecting the next device.The devices are listed together with the type information telling if it is a master or
slave device sorted by the current node address found on the PROFIBUS. By
activating the Refresh Timer the Live List can be updated automatically.
CycleTime
Use this function to read the current measured cycle time for the running
PROFIBUS.
Figure 24. CycleTime
The value for the cycle time is indicated in µsec. By activating the Refresh Timer the
cycle time can be updated automatically.
All devices, masters and slaves, connected to the PROFIBUS are shown,
independently of it whether they are configured and in data exchange or not.
