Abstract:
A multiple axis modular controller and a method of operating the controller in a system comprising input devices receiving indications of system conditions and output devices performing tasks affecting the system conditions. The controller includes input connectors connectable to the input devices and output connectors connectable to the output devices. A processor executes a series of sequential commands of an application program. A command can be executed in response to completion of one sequential command of the series of sequential commands regardless of a next sequential command in the series of sequential commands or in response to a specified input received at one of the input connectors or in response to a specified output sent to one of the output connectors. The processor does not execute the command, minimizing processor delays.
