1. A system for controlling industrial processes, the industrial processes requiring control of at least one process parameter, the system comprising: a controller including at least one processor operable to process a plurality of inputs and a plurality of outputs; at least one adjustment mechanism in electronic communication with said controller; a human-machine interface comprising a data entry device and a data display device, wherein the human-machine interface is operable with a plurality of detachable overlays, each of the detachable overlays being configured for a single industrial process and the detachable overlays being configured for at least two of the industrial processes of screen printing, die cutting or robotic material handling, the data entry device further including a plurality of keys configured into several groups with each group assigned a specific functionality, the specific functionality being identified by the detachable overlay and the plurality of keys being operable to define process parameters such that text may be specifically linked with the process parameters via the human-machine interface to facilitate industrial process control; a communication connection; memory; said controller, plurality of inputs and outputs, human-machine interface and communication connection are all resident upon a single circuit board; a high level programming language software module resident in said memory for interfacing with the human-machine interface; at least one modular software interface in electronic communication with the controller, written in machine language; and said processor being programmable to interpret at least one defined process parameter and link to at least one element of said human-machine interface.
