1756-PA72全新原装

详情描述：

在PLC系统设计时，首先应确定控制方案，下一步工作就是PLC工程设计选型。工艺流程的特点和应用要求是设计选型的主要依据。PLC及有关设备应是集成的、标准的，按照易于与工业控制系统形成一个整体，易于扩充其功能的原则选型所选用PLC应是在相关工业领域有投运业绩、成熟可靠的系统，PLC的系统硬件、软件配置及功能应与装置规模和控制要求相适应。熟悉可编程序控制器、功能表图及有关的编程语言有利于缩短编程时间，因此，工程设计选型和估算时，应详细分析工艺过程的特点、控制要求，明确控制任务和范围确定所需的操作和动作，然后根据控制要求，估算输入输出点数、所需存储器容量、确定PLC的功能、外部设备特性等，后选择有较高性能价格比的PLC和设计相应的控制系统。
