INSTRUMENTATION INFORMATION OUTPUT DEVICE OF REMOTE SUPERVISORY AND CONTROLLING UNIT

摘要

PURPOSE:To simplify a standard hardware constitution and a display change service by providing output set memories per display place units and adding different display addresses per display place units for each instrumentation information output from a slave station. CONSTITUTION:Instrumentation information signals from a slave station are made into series by memory counter 1 and are outputted to dynamic memory 2 as write data series signals 21. Then, memory counter 1 constitutes individual address signals 22 for write data synchronized with write data series signals 21 for controlling and scanning dynamic memory 2, output set ROM 3 and ROM 12 for system board display, word address signals 23 and slave station number signals 24 for write data and outputs them to dynamic memory 2 and ROMs 3 and 12.
