CPU315-2PN/DP conncects to a Wincc flexible RT via ethernet. ps:1.The pc is panel pc 677. 2.WCF RT is 2008 sp2. 3.cpu315-2PN/DP's f/w is v2.6.7(6ES7315-2EH13-0AB0) Question: I had set the PN PORT's IP address of cpu in hardware config of Step7. But I wired the ethernet to the PC.The PN port's leds were always black. The PN port didn 't work. Why ? How to set this PN port of CPU315-2PN/DP ? Tks. Angus.
