dierkens Posted October 17, 2022 Report Share Posted October 17, 2022 Quick question that I've been asked about a few times by clients and other controls engineers that I have a 'hard time' answering. We assign an IP Address to both the CPU and the HMI but we only ever use the HMI Address for anything such as MODBUS/TCP communications, VNC, FTP, etc. What's the purpose of the CPU IP Address if we never use it for anything? It' nice that the 2 ports are actually into a switch but if we can't really use the other IP Address then what's it for? This tends to come up when we need to communicate/access the PLC over different networks. Quote Link to comment Share on other sites More sharing options...
