Q: Shawn, I am the Maintenance Supervisor of my town’s Water Reclamation Facility. Yesterday the PLC that controls several critical pieces of equipment and interfaces with my SCADA system had a catastrophic failure and crashed. The program is gone and I don't have a backup. What can I do now?
A: Let me start by explaining that a PLC is a “programmable logic controller” which is basically a digital computer used to automate systems, machines or equipment.
Unfortunately your options are limited at this point.
