Duration memory device for arranging process - test point states

摘要

A system (100) for storing test point data indicative of the process condition in the normal embodiment of a primary process (116) at predetermined test points and the time a control process (122) in the event of failure of the primary process (116) reads the function of the primary process (116), whereby the system has the following features:a first processor nodes (104), which is configured to carry out process (116) primarily;a second processor nodes (106), which is configured to the process (122) is to carry out;a network interface (114) to an external network (112), wherein the primary process (116) and the control process (122) with the external network (112) are connectable; anda duration of memory unit (102) which, together with the network interface (114) is coupled, with the duration of the memory unit (102) is configured to the test point data via a direct memory write command from the primary process (116) through the external network (112) and the network interface (114) for receiving test point data (120) via a direct memory read command to the control process (122) via the network interface (114) and the external network (112) to provide,a remote direct memory access is implemented, in order to enable the first and second processor nodes (104, 106) to exchange information in a memory of the duration of memory unit (102) directly to store and to recover andwith the duration of the memory unit (102) is configured to set a virtually - to - physically - via address, and vice versa, is to provide.
