三、系统配置

    海维深科技有限公司生产的V80 系列PLC 是一款高性能、低价格的小型可编程控制器。具有简易人机功能,支持数码管显示和键盘输入功能,且不占用I/O 点,可以方便地将3 个时间值设置到PLC,取代了易损坏高成本的时间继电器。V80 系列PLC 是真空包装机系统的控制核心,通过它控制的外围设备有真空泵、充气泵、加热电丝和位置检测开关等。

V80 系列PLC 配置如下:
 

四、程序设计

    真空包装机控制程序设计的难点在于档位切换脉冲的实现和过程切换时当前过程输出需要复位。档位切换脉冲的实现由输入状态的改变产生一个上升延脉冲完成,程序如下图:
 

     过程切换的关键是要复位中间寄存器和输出变量,(SET)指令必须在切换脉冲产生时执行(RST)指令,寄存器复位为0。
 

五.结束语

     真空包装机电气控制系统由V80 系列PLC 构成,与原先PLC 构成的电气控制系统比较具有明显的优势,主要表现在通过简易人机代替了多个时间继电器,节省了PLC 的IO 点和避免了时间继电器容易损坏的问题,提高了设备的可靠性,产生了良好的经济效益。

     在真空包装机中的应用表明,V80 系列PLC 是一款性能价格比较高的小型可编程控制器,较适用于小型机械设备的电气控制系统,主要体现在以下几点:

1. 价格低,能很好的控制设备成本。
2. 具有简易的人机功能。
3. 编程简单,电气工程师上手容易。
4. 优异的在线编程和监控能力,非常实用于现场调试。
