Method and device for tabular processing and execution of operation flow, and generation of an operation flow table by the same. The flow steps of the operation flow are sequentially acquired and the continuous flow steps in the operation flow are combined into a flow step sequence corresponding to the operation flow type according to the predetermined flow step sequence combination rule. Based on a predetermined row generation rule corresponding to the flow step sequence having the operation flow types, in the operation flow table, the operation flow table rows corresponding to the flow step sequence are sequentially generated until all the flow steps are processed and a final operation flow table is outputted. The operation flow table is executed by the aforesaid method and device. The editing, processing and execution of the complex operation flow can be made more concise and efficient by the aforesaid operation flow processing.

A static safety analysis for control-flow linearization receives a control flow graph (CFG) and an intermediate representation of a computer program, and identifies, for a given loop, all memory load instructions belonging to one side of a diamond-shape structure in the CFG. For each representation of an address of each memory load instruction identified, determining whether it is used on all other sides of the diamond-shape structure. Responsive to determining each representation of an address of each memory load instruction on the one side of the diamond-shape structure is used on all other sides of the diamond-shape structure, determining whether an immediate predecessor of a top of the diamond-shape structure for the given loop post-dominates a header of the given loop. Responsive to determining the immediate predecessor of the top of the diamond-shape structure for the given loop post-dominates the header of the given loop, affirming safety of linearization.

A system and method providing device configuration using quick response (QR) and/or other machine readable codes. The system and method reduce the time and costs associated with configuring devices/equipment based on site plans while also reducing the potential for errors during the configuration process.

In a method for operating a production machine or machine tool, an app having at least one virtual container and an app configuration is downloaded from a remote memory store into a memory store of the machine, and an immediate start of the downloaded app on the production machine or machine tool is automatically prevented. The app configuration of the downloaded app is then automatically modified, and identifiers included in the app configuration are automatically evaluated and compared with identifiers included in a positive list or in a positive list and a negative list. An identifier which is not contained in the positive list, or an identifier which is contained in neither the positive list nor in the negative list is automatically replaced with an automatically selected or automatically generated target expression; and the downloaded app following the modification of the app configuration is then automatically started.

In the invention, a problem is solved in which, in order to achieve high performance and high reliability with the conventional multi-core and lockstep core, a redundant lockstep core is necessarily prepared to execute a multi-core program in which an error has occurred, a circuit area increases, and a cost and a power consumption increase. In the invention, a safe operation of a control system is secured by operating a software program operating on a multi-core in which an error has occurred as degenerate software on a core switched from a lockstep operation to a multi-core operation.

An interactive software application on a mobile computing device is used to configure an electronic torque wrench via a wireless connection. The software application obtains torque specifications for a vehicle from a remote database. When the torque specification require that work pieces be torqued in an ordered sequence, the software application guides the technician through the sequence, but accommodates changes when the technician departs from the sequence.
