GE DL-1200 RTU电力调制解调器
PROFIBUS电源集线器SK3 PROFIBUS电源集线器是Pepperl+Fuchs的新PROFIBUS DP/PA连接设备，是SK2系列的后继产品。与SK2和LD 800P相比，PROFIBUS Power Hub SK3提供了增强的PROFIBUS功能。这可以配置为DP从设备，并支持从设备冗余。当使用AC 800M和CI854进行配置时，只有PROFIBUS Power Hub与非冗余或冗余的活动从设备功能一起使用。在全透明模式下（PROFIBUS Power Hub DIP开关上的从站地址配置>126），CI854与连接的PA从站的通信可能偶尔出现故障或无法工作。这是因为在全透明模式下，SK3的行为类似于SK2，SK2具有透明看门狗和等于1的重试限制作为默认设置。有关更多信息，请参阅“从P&F链接设备SK2”
PROFIBUS Power Hub SK3
The PROFIBUS Power Hub is a Pepperl + Fuchs’s new PROFIBUS DP/PA linking
device, successor of the SK2 resp. The PROFIBUS Power Hub SK3, compared to SK2 and LD 800P, provides enhanced PROFIBUS functionalities. This can be
configured as a DP-slave and it supports slave redundancy.When configuring with AC 800M and CI854, only the PROFIBUS Power Hub is
used with active slave functionality as non-redundant or redundant. In a full
transparent mode (slave address on DIP-switch of PROFIBUS Power Hub
configured > 126), the communication of CI854 with the connected PA-slaves
might sporadically become faulty or it may not work. This is because in a full
transparent mode, the SK3 behaves similar to the SK2, which has a transparent
watchdog and a retry limit equal to 1 as a default setting. For more information
