Caffination Station The purpose of this project was to become familiar with the HiGraph (Graphical State Machine) and SCL (Structured Control Language) features within the Siemens S7-300 series PLC.

We took it upon ourselves to further explore the Human Machine Interface (HMI) capabilities and closely integrate the HMI into the project over a Multi-Point Interface (MPI) network .

Check out the demonstration video on the project sub-site


The purpose of this project was to use two standalone Programmable Logic Controllers (PLCs) where one is simulating a process (with artificial noise and disturbances) and the other PLC is acting as a controller. We decided to also include a Human Machine Interface (HMI) to allow the for both monitoring of key information and to adjust/reset the controller parameters.  Click Here to be taken to the dedicated sub-site
