The reason you will need to bridge the connection in order to use the discovery protocol is because it is a Layer 2 protocol. NOTE: You may need to disable firewalls on your VM and PC, depending on any pre-existing security protocols. To establish connection to the PLC, you will first need to verify that your VM connection is bridged to the computer’s network adapter.Īfter bridging the connection, navigate to “Virtual Network Editor” and manually change the settings to bridge the VM to your physical port. For scenarios where the TIA Portal software platform needs to be installed on a VM, we are able to use a VM to connect to a physical PLC to download, upload, and perform online troubleshooting by following the below process.
To remedy this situation, a Virtual Machine (VM) is an efficient approach that mirrors a computer’s operating system and provides the full functionality of that operating system without the need for additional hardware. Maximum length 4000 feet (1.2 km) connector RJ 45 (radio jack).ģ) MPI :- multi Point interface bound rate 1.5 mbps default,187.5 kbps, no of maximum nodes 32, network length 4000 ft, MPI use for PLC programming, inter CPU Communication, Scada/HMI communication.Ĥ) Profibus:- Process field bus, Bound Rate 12 mbps, no of maximum nodes 126, network length 4000 ft, Profibus also used for remote I/Os and drives Communication.Occasionally the situation will arise where a customer will need to support multiple automation platforms that may come in conflict with one another, or software packages that are required to run on different operating systems. connector nine pin delta.Ģ) DH485:- Data Highway,32node components, bus rate 19,200 bit/sec.
