则模块将输出对应于当前范围低端的数据字（以%AI表示的0000H）。如果输入的输入超出范围（即大于20 mA），A/D转换器将输出至满量程（对应于%AI中的7FFFH）。电压操作在0到+10 V的默认范围内，用户数据被缩放，使得0伏对应于0的计数，+10伏对应于32000的计数。通过使用Logicmaster 90-30/20/Micro组态软件或手持式编程器更改A/D（十进制）CURRENT（mA）a44654 0 20 0 4000 0至20 mA range IC693ALG442模拟组合I/O模块12 GFK–0898F2章–IC693ALGA442模拟复合I/O模块12-5配置参数，选择-10至+10伏范围。在–10至+10伏范围内，用户数据被缩放，因此–10伏对应于–32000的计数，+10伏对应于+32000的计数。在任何一个范围内都可以使用完整的12位分辨率。由于模拟输入通道中使用的转换器是12位转换器then the module will output a data word corresponding to the low end of the current range (0000H in %AI). If an input that is out of range is entered (that is, it is greater than 20 mA), the A/D converter will output up to full scale (corresponding to 7FFFH in %AI). Voltage Operation In the 0 to +10 V default range, user data is scaled so that 0 volts corresponds to a count of 0 and +10 volts corresponds to a count of 32000. The –10 to +10 volt range is selected by changing the A/D (decimal) CURRENT (mA) a44654 0 20 0 4000 0 to 20 mA RANGE IC693ALG442 Analog Combination I/O Module 12 GFK–0898F Chapter12 – IC693ALG442 Analog Combination I/O Module 12-5 configuration parameters using the Logicmaster 90-30/20/Micro configurator software or the Hand-Held Programmer. In the –10 to +10 volt range user data is scaled so that –10 volts corresponds to a count of –32000 and +10 volts corresponds to a count of +32000. Full 12-bit resolution is available over either range. Since converters used in the analog input channels are 12-bit converters, not all of
