We installed an ESXi server and multiple VMs, and set up our PLC to communicate with the VMs. We also installed a light tower and wired the I/O to the PLC. We installed Ignition SCADA and connected it to our PLC in the lab, and used various tools to scan our install and detect open ports and paths that a developer may have left open on the web-based SCADA system.
