In this blog, we learned how to setup a connection with the Koyo CLICK PLC and to write a basic ladder logic program. We wired up X1-X4 inputs and observed how outputs Y1-Y4 lights up respective to their inputs. In our PLC Hacking Part 2 blog, we will delve into overriding data and how to interact with the PLC using industrial communication protocols like Modbus TCP and Ethernet/IP.
In our “PLC Hacking” series, we are going to cover different methods of interacting with PLCs, the different protocols which they use, and to demonstrate their inherent lack of security protection. In this particular blog, we will be looking at setting up the PLC and writing a ladder logic program into it.
