Semigraphic information imaging at power unit control room

A semigraphic colour display device was developed for computer-based information systems in Czechoslovak nuclear power plants. This is an intelligent terminal which receives data on the state of the power plant unit from the unit or the standby computer of the information system. The terminal has its own microcomputer, the SM 50/40 which in its memory stores data on the form of display, static background, etc., so that from the information system it only needs the current values of monitored data. The terminal consists of standard modules of the SM 50/40 modular system, the only non-standard part is the interface card serving the connection of the ODI-6310 display which in pairs provide the display of information and which do not have the interface to computers of the SMEP series, for paging and for communication with computers of the information system. The terminal is at present connected to the RPP-16 computer but communication with computers of the information system is by serial transfer and thereby independent of the computer type. (Z.M.)
