Fetch data from S7 PLC Profibus DP
#4
Hello Madmumati,

a single Ethernet port of course can connect to another single ethernet port only. It's a peer to peer connection.

If you want to extend a single Ethernet port to multiple then you simply have to use an Ethernet n-port Switch with multi-port capability.

But with a switch all devices are sharing the same network. But sometimes customers want to divide networks into sections cause of security reasons e.g. PLC network and office network and in this case you need a firewall or a managed switch.

But if you say in your application Wifi connectivity is allowed and then of course Wifi connection can be used, but please do not forget that netPI wifi antenna is static and cannot be extended. So if netPI is mounted in a control cabinet and you close the cabinet doors, then Wifi signals are shielded by the cabinet and will not work. So in my opinion using Wifi is not a perfect solution.
