CONNECTION OF CHECKING AND CONTROL MODULUS

摘要

The design concerns the module for interaction of operators with the microprocessor control system. The microprocessor activates the controller via its address output, and at the same time via its control output sets the operating mode to the controller thus determining whether it concerns data display or data acceptance from the button field. The set data from the button field are transferred to the data bus of the system by the controller. The controller activates the individual elements of the display unit via the display decoder and set decoder and at the same time converts the data from the system bus into the control signal for the individual segments of the display unit. The data, which are set to the control system via the checking and control module and which characterize the parameters of regulating processes of the system, monitored levels of operational values, and schedule of operating system activities, are stored in the memory with random access and secured supply. It can be utilized in heating and air-conditioning engineering.<IMAGE>
