A FICTION SIMULATOROF IMAGINATION INPUT OUTPUT SIGNAL IN DISTRIBUTED CONTROL SYSTEM

摘要

The present invention provides a virtual input and output signals to the distributed control system relates to, which may be identical to the simulator and the actual simulator, the input and output virtual simulator; to process (IO Simulator Program 11) and the output virtual simulator program 11 (; 12 Application Program Imterface Dynamic Link Library), the API (12), 48-bit digital input and output card are connected to the API (bIT dIGITAL oUTPUT cARD; 13), a relay driver circuit connected to the 48-bit digital input and output card 13 consists of a 14, the 48-bit digital input and output card (13) includes an optical coupler and resistor 21, 22 and the address decoder and read / write logic 23, output register 24, a bus buffer 25 and consists of a base address switch 26 to give a range of variation as in the example is a skilled man in the art was the function information, configuration can be achieved which is capable of freely operating Am related to the actual control of the application of the plant and the batch load sharing of the plant was treated in a separate and write without committing the time and error debug a section (Section) to (Debug) workers (operator, system management, maintenance personnel ) it will be ambitious in the benefits that can be significantly reduce the burden and load balancing.
