<p>When the execution of the application program (20) is in periodic mode, the linked task (20) includes validating means (120) which authorizes the operation of the communication management module between the end of the program (20) cycle and the start of the following cycle. The management module (30) includes a first sub-module which uses a memory zone to memorize transmitted data or destination of program (20). Automation equipment having a central unit (1) which possesses, memory (2,3), real time operating system (10) and application program (20) designed to effect control or communication function in an automation application. The equipment includes a TCP/IP network driver (40) which is directly integrated in the unit (1) without passing by a basket bottom bus. The operating system (10) of the unit (1) includes a communication management module (30) for the network TCP/IP (4) and a servo-control (12) designed to control the execution of the module (30) to the characteristics of the automation application so as not to interrupt the operation of the program (20).</p> |
