Hi All,
I am in the middle of connecting some machinery to our compnay LAN for data acquisiton via Factorytalk Historian. I am running into some issues with IT who are reluctant to give static IPs and and allow the equipment to be connected to the network referencing viruses such as Stuxnet.
To try and persuade them to allow connection I have said that I will install a seperate NIC on the machines and essentially greate a VLAN with an internal and external network. So the HMI running windows will not be directly connected to the external (company) network.
My question to you is, does this VLAN solution make sense or is their a better solution when connecting PLCs to a company network that will deliver added security.
Can a virus jump from one NIC to the other.
Appreciate any help.
Dave.
