We are planning to install a AB7831 X-Gateway with Ethernet IP Slave for both networks, to connect 2 PLCs together. We need to exchange data between the 2 PLCs at a site, but want to make sure they are still isolated for security reasons. 1 PLC is ours, the 2nd PLC is a partner of ours, but does not belong to us.
The isolation is to protect from erroneous downloads, accidental of malicious activity on either networks, etc.
What is the best solution? Is the X-Gateway itself enough? Or is there a best practice of adding an intermediate switch with VLAN on each end or something?
NOTE: I am not completely IT savvy…but do have access to our IT department to forward suggestions…
