从而0V对应于计数0，10V对应于计数32767。每个模拟输出能够提供四个输出范围（两个电压和两个电流）：0至+10伏（单极）-输入和输出通道的默认范围10至+10伏（双极）0至20毫安4至20毫安每个输出通道能够将15至16位（取决于所选范围）二进制（数字）数据转换为模拟输出，以便根据您的应用需要使用。12 12-2系列90–30 PLC I/O模块规范中的用户数据–2000年7月GFK–0898F%AI和%AQ寄存器采用16位2的补码格式。在当前模式下，每个通道的CPU都会报告开路故障。当系统电源中断时，模块可以进入已知的后状态。只要用户向模块供电，每个输出都将保持其后值，或重置为刻度（范围）的低端，具体取决于模块的配置方式。每个输出通道可配置为在斜坡模式下运行scaled so that 0V corresponds to a count of 0 and 10V corresponds to a count of 32767. Each analog output is capable of providing four output ranges (two voltage and two current): 0 to +10 volts (unipolar) - default range for both input and output channels. –10 to +10 volts (bipolar) 0 to 20 milliamps 4 to 20 milliamps Each output channel is capable of converting 15 to 16 bits (depending on the range selected) of binary (digital) data to an analog output for use as required by your application. User data in 12 12-2 Series 90–30 PLC I/O Module Specifications – July 2000 GFK–0898F the%AI and %AQ registers is in a 16-bit 2’s complement format. In current modes, an open-wire fault is reported to the CPU for each channel. The module can go to a known last state when system power is interrupted. As long as user power is applied to the module, each output will maintain its last value, or reset to the low end of the scale (range), as determined by how you have configured the module. Each output channel can be configured to operate in ramp mode
