    • A programming module for programming a number of programmable read only memory (PROM) units secured onto a single memory module for use at a selected location of several locations in a programmable controller using a microprocessor operated on a low order logic voltage level and having output address lines, and input/output bi-directional data lines and having means for creating a read signal in a read line and a write signal in a write line. The programming module comprises an input side with terminals connected with the address lines, the data lines, the read line and the write line and an output side having address terminals, program voltage terminals and data terminals for connection with the single memory module to be programmed. The programming module includes its own high level program voltage power source and decoding means for decoding a memory address and applying a programming voltage to a selected PROM unit in response to an address received by the programming module.
    • 一种编程模块,用于编程固定到单个存储器模块上的多个可编程只读存储器(PROM)单元,用于使用在低阶逻辑电压电平上操作的微处理器并且具有输出地址的可编程控制器中的多个位置的选定位置 线和输入/输出双向数据线,并且具有用于在读取行中产生读取信号和写入信号的装置。 编程模块包括具有与地址线,数据线,读取线和写入线连接的端子的输入侧,以及具有地址端子,编程电压端子和数据端子的输出端,用于与要编程的单个存储器模块连接 。 编程模块包括其自己的高级编程电压电源和用于解码存储器地址并且响应于编程模块接收的地址将选择的PROM单元应用编程电压的解码装置。
