UDK-04-109自动化模块
格式转换该模块能够将数字化数据以任何一种原始二进制形式呈现给PC（RB）或转换的二进制（CB）格式。每种情况下的位模式都不同。这个格式是开关可选的，每组输入电路的格式不必相同。
Modicon程序员将以三种不同的方式之一显示任一类型的数据：二进制、十六进制或十进制形式。
转换精度该模块的转换线性为满量程的0.05%–参考直线穿过测量满标度值和测量零点的线–超过模块的工作温度范围。
原始二进制（RB）格式输入信号数字化后，输入模块显示RB格式的数据。在十进制表示法中，RB格式的数据必须在0至4200范围。通常，12位设备的数据上限为4095。
该模拟模块具有允许输入超过范围2%的方法以相同的分辨率（即，原始二进制中的计数可以达到4200）。在RB格式中，无论电压范围如何，数据范围都是相同的。
转换二进制（CB）格式CB通过转换RB格式获得在模块中。
当PC或程序员以十进制查看CB数据时模式下，它看起来像一个没有符号或小数点的4位数字电压表（DVM）。在CB格式中，上限和下限数据取决于电压范围。因为缺少符号，CB格式仅用于单极电压范围。
下图显示了原始二进制输出的示例。当5 V信号为通过设置为0至10V范围的模块进行数字化，它生成一个转换的二进制代码0800十六进制或2048十进制。诊断通信诊断程序在五秒钟的初始化期间执行随后通电。诊断例程也在并发等待状态期间运行执行A/D转换。系统诊断包括：RAM检查、ROM检查、UART检查以及检查配置开关的合法性设置和监控自动校准的能力。
Diagnostic Communications
Diagnostic procedures are executed during the five second initialization period following power--up. Diagnostic routines are also run during wait states concurrent with executing A/D conversions. System diagnostics are: RAM checks, ROM checks, UART checks, as well as checking the legality of configuration switch settings and monitoring the ability to autocalibrate.
Format Conversion
The module is capable of presenting the digitized data to the PC in either raw binary (RB) or converted binary (CB) format. The bit pattern in each case is different. The format is switch selectable and need not be the same for each group of input circuits. A Modicon programmer will display either type of data in one of three different ways: binary, hexadecimal, or decimal form. Conversion Accuracy Conversion linearity for this module is 0.05% of full scale–referenced to a straight line drawn through the measured full-scale value and the measured zero point–over the module’s operating temperature range. Raw Binary (RB) Format After digitizing the input signal, the input module presents data in RB format. In decimal representation, data in RB format must be within the 0 to 4200 range. Normally, a 12--bit device would have an upper data limit of 4095. This analog module has the means of allowing the input to be up to 2% over-range at the same resolution (i.e., the count in raw binary may go up to 4200). In RB format, the data range is the same regardless of the voltage range. Converted Binary (CB) Format CB is obtained by transforming the RB format within the module. When CB data is viewed by the PC or programmer in decimal mode, it looks like a 4-digit voltmeter (DVM) with no sign or decimal point. In CB format, upper and lower data limits are voltage range dependent. Because of the missing sign, CB format is used only for unipolar voltage ranges. The following figure shows an example of raw binary output. When a 5 V signal is digitized by the module set for 0 to 10 V range, it produces a converted binary code 0800 hex or 2048 decimal.
