As for the linear network, DP and PN are different. If one or several nodes in the DP network are powered off, the DP linear network may still be connected, and the communication of subsequent nodes may not be affected; The PN is different. If the middle node of the linear network is powered off, the subsequent nodes will definitely be blocked. This is why the PN network must implement MRP medium redundant ring network. Even with the MRP medium redundant ring network, it is still inferior to DP in some cases, such as the power failure of several nodes in the linear network. In the DP network, communication is possible as long as there is no power failure, but even if the PN [Detailed]
