I am trying to get some feedback from other Control System users/providers. What is your opinion on interconnecting or not interconnecting Control System LANs with Business LANs? From a control point of view I personally would like to seem them physically separated for security of the Control System, with routers/firewalls to connect to the business LAN for Database/SQL type applications. Does anyone have experience with combining the two? Either using the same physical network with different protocols, domains and/or sub-nets?
On a similar note, what about having business application on the same workstation as the HMI software for the Control System? Is it reasonable to claim two separate boxes are required and that business software should no co-exist on the HMI box?
Thanks in advance for any comments.
