Hi, I was reading this post about what is the difference between Terminnal bus & Plant bus? and this is clear for me. "This means Terminal bus is on TCP/IP protocol in which devices communicate with each other over IPs where as Plant bus is on OSI/ISO protocol in which devices communicate with each other over MAC address" I have the next question. I have a server with three virtual machines, 1 OSServer, 1 OSClient and 1 ES. I have the posibility to use 2 network ports, one for plant bus and the other network port for terminal bus, but can I use these network ports from my application (one for terminal bus and the other for plant bus) but both with TCP/IP or Plant bus only works trough OSI/ISO? In another post I read that it is advisable to separate both networks (plant bus and terminal bus) for performance reasons, for that reason I made the decision to use two network ports of my server, one for one network and the other port for the other. network (bus terminal) But is this possible? |

Hi Cristian, you can merge or separate the Terminal Net and the Plant Net, from PCS 7 side is there no limitation (nowadays you can use TCP/IP on the Plant Net). The reason why you separate the Terminal Net and the Plant Net is that PCS 7 is a process control system which should be high available. So a problem on the Terminal Net should not affect the Plant Net. Also the performance is better if you separate the two networks. And the best way separate the Terminal Net and the Plant Net is with two network cards. In your virtuell system you can assign two networks card to the ES and OS servers. Then use one for the Plant Net and one for the Terminal Net. And it is a requirement if you separate the two networks that both networks have different sub nets. And that you don't have a CP card for your system is no problem. You can use the conventional network cards if you configure in your project the network card with "ie general". Please consider that you need an additional license (BCE or SIMATIC NET) if you want to use the conventional network card for the Plant Net at the OS server. For more details of the BCE or SIMATIC NET license see the post BCE License or SimaticNET or Other? With regards |
