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.
