I tried to connect the SIEMENS IM 151-8 PN/DP CPU first time over PROFINET with my PC. I started the Siemens Port Configurator and included the PROFINET mode as well as the IO-Link master. But I don't know how to configure the IP address. It's not clearly mentioned in the Siemens manual. It's showing me connection error. Only thing I know is that MAC address is mentioned on the CPU box. Please help me with this.
