1756-OA8D/ABPLC模块

 1756-OA8D/ABPLC模块

由于PLC容易与工业控制系统连成一个整体，易于扩展功能，具有接口简单快捷、工作量小、适合于较为恶劣的运行环境、故障率低、可靠性好、抗电气*力强，维护方便等优点。

3.4  PLC采用扫描式的工作方式，特别适合于逻辑控制要求较高的顺序控制。

3.5  我厂的顺序控制系统流程较为复杂，90年代前期所用常规的继电器硬线控制方式规模庞大、维护困难、故障和事故发生机率较高，出现故障后不利于查找并消除故障，设备隐患较多，在我厂采用传统方式的继电器顺序控制方式，其安全生产记录常常打破，我厂采用PLC控制后，不仅提高了设备可靠性，而且对设备的检修维护都十分方便快捷，无需将机组及附属设备退出运行即可解决，大大提高了工作效率，而安全生产记录已接近3000天，创历史高记录。
