S7-200模拟量使用应该搞清的16个基本问题

1. 什么是单极性、双极性? 双极性就是信号在变化的过程中要经过“零”,单极性不过零。由于模拟量转换为数字量是有符号整数,所以双极性信号对应的数值会有负数。在S7- 200中,单极性模拟量输入/输出信号的数值范围是0-32000;双极性模拟量信号的数值范围是-32000-+32000。

2. 同一个模块的不同通道是否可以分别接电流和电压型输入信号? 可以分别按照电流和电压型信号的要求接线。但是DIP开关设置对整个模块的所有通道有效,在这种情况下,电流、电压信号的规格必须能设置为相同的 DIP开关状态。如0-5V和0-20mA信号具有相同的DIP设置状态,可以接入同一个模拟量模块的不同通道。

3. 模拟量应该如何换算成期望的工程量值? 模拟量的输入/输出都可以用下列的通用换算公式换算:Ov=[(Osh-Osl)*(Iv-Isl)/(Ish-Isl)]+Osl其中:Ov:换算结果;Iv:换算对象;Osh:换算结果的高限;Osl:换算结果的低限;Ish:换算对象的高限;Isl:换算对象的低限 。

4. S7-200模拟量输入信号的精度能达到多少? 拟量输入模块有两个参数容易混淆:1)模拟量转换的分辨率2)模拟量转换的精度(误差)分辨率是A/D模拟量转换芯片的转换精度,即用多少位的数值来表示模拟量。S7-200模拟量模块的转换分辨率是12位,能够反映模拟量变化的 小单位是满量程的1/4096。模拟量转换的精度除了取决于A/D转换的分辨率,还受到转换芯片的外围电路的影响。在实际应用中,输入的模拟量信号会有波动、噪声和干扰,内部模拟电路也会产生噪声、漂移,这些都会对转换的 后精度造成影响。这些因素造成的误差要大于A/D芯片的转换误差。
