Abstract: A control architecture includes at least one programmable logic controller and at least one cloud computing system. An automation program of the controller includes at least one predefined control module. The cloud computing system is designed to store first data in accordance with a model of input data and second data in accordance with a model of output data. At least one first hardware and/or software entity is designed to publish the first data in the cloud computing system with a view to being read by the programmable logic controller when it executes the predefined control module. At least one second hardware and/or software entity is designed to read the second data published in the cloud computing system by the programmable logic controller when it executes the predefined control module.

Abstract: A system and a method for scheduling an automation process controlling a machine. The system including a parser module for parsing calendar data, the calendar data comprising calendar events including clock data and task data. The system further including a clock module for monitoring time instances and triggering the parser module to parse the calendar data to retrieve the task data of a calendar event that is identified by clock data corresponding to a time instance; and a task module for processing the task data of the calendar event to obtain machine control data for execution on a machine.

Abstract: An automation equipment includes a system unit and a driver. The system unit has at least one memory including a real time operating unit and an application program unit that performs monitoring or control functions in an automation application. The driver is directly included in the system unit and is configured to connect to a TCP/IP network without going through a back panel bus. The operating unit of the system unit includes a communications management module configured to communicate to the TCP/IP network, and a control task unit responsible for controlling execution of the communications management module, the control task unit being directly connected to the communications management module to avoid disturbing an operation of the application program unit.

Abstract: The present invention relates to a communications system in a programmable controller comprising smart modules, a network module connected to a TCP/IP network and an internal communications bus, for example the backplane bus connecting all the modules of the programmable controller with each other. The communications system enables exchanges of information in compliance with the TCP/IP protocol, to be performed on the internal communications bus. Each smart module has its own IP address and a TCP/IP stack. The communications bus includes several separate communications channels providing for simultaneous flow of the frames complying with the TCP/IP protocol together with frames complying with other protocols. The invention also relates to a programmable controller capable of implementing such a communications system.
