Programmable logistics cloud computational controller

A method for sampling and processing input/output signals extracted from a a programmable logic controller (PLC), the method comprising:

• coupling a controller of an electronic device to the PLC via a communications line;
• receiving, with the controller of the electronic device, signals from the PLC;
• sampling, with a graphics processing unit (GPU) of the electronic device, the received signals and arranging the sampled signals as a graphical signal representation;
• and
• processing, with the GPU of the electronic device, the graphical signal representation and preparing the processed graphical signal representation for transmission to a cloud-computing environment.

An electronic device configured to communicatively couple to a programmable logic controller (PLC) controlling and monitoring a process, the electronic device comprising:

• a controller configured to receive signals from the PLC, wherein the electronic device is configured to couple the controller to the PLC via a read only communications line, and wherein the received signals are extracted from the PLC by the controller;
• and
• a graphics processing unit (GPU) configured to sample the received signals, and to arrange the sampled signals as a graphical signal representation;
• wherein the GPU is configured to process the graphical signal representation to detect errors in the graphical signal representation which are indicative of errors in the process.
