NCLibrary V 2.1
Instructions and Graphics ( MonAn08 )
应用场合举例：
大型电机减速机和辊的轴瓦、电机转子等多点测温，都是多个温度输入，需要对其进行报警和联锁保护。
显示8个模拟量值，并对其进行归档
计算测量模拟量值的Zui大值（Max），Zui小值(Min )和平均值(Ave)，可以三选一作为报警过程值
断线坏值显示并报警 (图中红线方框标记)
自动剔除模拟量坏值，坏值不参与Zui大值Zui小值平均值的计算
—————————————————————————————————————————————————
PV1~8连接模拟量过程值
Bad1~8连接模拟量过程值评估结果
Mode模式选择
