大量的运行实例已经表明,计算机是提高工业生产控制水平的有力工具.随着计算机控制规模和应用领域的扩大,运行可靠性问题也就相应地显得更为突出和复杂.我厂引进的乙烯生产装置中,配备了一台MELCOM-350-5F型(简称M-5F机)的小型工业控制机对六台裂解炉进行控制,并完成整个装置的生产数据处理.M-5F的字长16位,内存16K,外存128K,配有四台记录打字机,一台制表机,一台光电机,一台穿孔机和一个工艺操作台.在外围设备中,包括653点模拟量输入,97点数字
A large number of operational examples have shown that the computer is a powerful tool to improve the level of industrial production control.With the expansion of the scale and application of computer control, the reliability of the operation accordingly becomes more prominent and complex.Our plant to introduce ethylene production In the installation, a small industrial control machine equipped with a MELCOM-350-5F (referred to as M-5F machine) controls six cracking furnaces and completes production data processing of the entire plant. The M-5F has a word length of 16 bits , Memory 16K, external memory 128K, equipped with four record typewriters, a tabulation machine, a photoelectric machine, a punch and a process console.In the peripheral equipment, including 653 analog inputs, 97 points digital
