FIELD: engineering of controlling and adjusting systems for controlling technological processes. ^ SUBSTANCE: complex contains workstations and servers based on personal electronic computer machines, connected as a local area Ethernet network, and also controllers and functional modules. Programmable logical integral circuits, built into each functional module, support programming of practically any algorithms for processing signals and control, adequate for tasks, assigned by engineer to current module. Three variants of system engineering are possible on basis of means included in complex: centralized control, local control, distributed control. In all three variants central microprocessor module controlled by software performs primary configuring of functional modules, information exchange, control and diagnostics of software and hardware means. ^ EFFECT: expanded functional capabilities, increased reliability, improved maintainability. ^ 14 cl, 19 dwg |
