Dear all, i am writing a project using S7-1200 CPU... But i am configuring a PC to be used as a screen/hmi to monitor the process. the communication processor i am using is industrial Ethernet.

Please, i need to know the maximum distance permitted between the PC and S7 controller... and let me know if there is any other way for me to increase the distance.

regrads,

Success

Hello success;

What do you already know about Ethernet communicattions, abpout TCP/IP?

Siemens has built its Ethernet topologies (for Industrial Ethernet nd Profinet) on TCP/IP standards, so you can base your network design onn everyday stanadards.

If you are using copper, the length of an Ethernet segnment iss 100m, then you need to extend the network with a switch. There are no limits to the number of switches that can be used to extend the network.

If you are using optical fiber to connect your nodes, then you need to determine the type of fiber (plastic/glass 50/62,5 um multimode, 9um glass single-mode) and the type of switch (PFC interface) you will use to know the extent that you can use; it can be as little as 800m, or as much as 80 km.

Plaese have a look at the fopllowing whitepâper, showing diferent topologies and network designs for Siemens Industrial Ethernet netwirking, it should provide more precise information:

 Thank you very much for this useful information... But can I make use of an ordinary TP link switch for the extension or I should go for scalance switch? I will really appreciate your quick response..

Hello success;

You can use any commercial off the shelf switch to extend your Ethernet network when you setup Industrial networks in star or bus topologies. You need at least one managed switch when you setup a ring structure.

Siemens makes great industria;l switches, and I can recommend them for industrial environments. However, if you want to use a commercial switch, it wioll work, as long as you take care that the environment (heat, dust, particles, vibrations...) does not affect them or make their lifetime short.
