所有C系列组件均采用创新设计，支持增强的热管理。这种独特的外观大大减小了等效功能的整体尺寸。C系列I/O的独特功能包括:

·l/O模块和现场端接组合在同一区域。I/O模块插入IOTA，无需单独的机箱来固定电子组件。·两级“可拆卸"端子，用于将现场布线固定在机柜中，使设备安装和维护更加容易。

现场电源通过IOTA提供，无需额外的电源和相关的工艺接线。

·只需向IOTA添加第二个IOM，即可直接在IOTA上提供冗余，无需任何外部布线或冗余控制设备。

·CC-MCAR01 C系列的创新造型是其独特之处之一。此样式包括便于在系统环境中有效使用控制硬件的功能。这些功能包括:垂直安装可实现更有效的布线，因为大多数现场布线应用需要从系统机柜的顶部或底部进入。

模拟量输入模块是一款将远程现场的模拟量信号采集至计算机的设备，其利用RS-485总线作为数据通信线路，提供模拟量转485功能，能够同时将模拟量输入至模块，并通过RS-485总线传输至计算机。由于采用RS-485接口作为通信接口，其能够多个模块组合传输更多路数模拟量信号，并且能够在485线路上分散配置，采用地址码进行区分，可以直接接入MODBUS RTU协议的组态软件。

在PLC里面，CC-MCAR01模拟量有效信号通常用模拟量输入/输出映像寄存器（AI/AQ）来表示。模拟量输入电路是将外部输入的模拟量信号转换成1个字长的数字量存入模拟量输入映像寄存器区域，区域标志符为AI；模拟量输出电路是将模拟量输出映像寄存器区域的1个字长（16位）数值转换为模拟电流或电压输出，区域标志符为AQ。在PLC内的数字量字长为16位，即两个字节，故其地址均以偶数表示，如AIW0、AIW2......；AQW0、AQW2......。对模拟量输入/输出是以2个字（W）为单位分配地址，每路模拟量输入/输出占用1个字（2个字节）。如有3路模拟量输入，需分配4个字（AIW0、AIW2、AIW4、AIW6），其中没有被使用的字AIW6，不可被占用或分配给后续模块。如果有1路模拟量输出，需分配2个字（AQW0、AQW2），其中没有被使用的字AQW2，不可被占用或分配给后续模块。

All C-Series components are innovative in design to support enhanced thermal management. This unique appearance greatly reduces the overall size of the equivalent function. The unique features of the C Series I/O include:

·l/O modules and field terminations are combined in the same area. I/O modules plug into IOTA, eliminating the need for a separate chassis to hold electronic components. Two-stage "detachable" terminals for securing field wiring into the cabinet, making installation and maintenance easier.

Field power is provided via IOTA, eliminating the need for additional power and associated process wiring.

Simply add a second IOM to IOTA to provide redundancy directly on IOTA without any external cabling or redundant control devices.

· The innovative styling of the CC-MCAR01 C series is one of its unique features. This style includes features to facilitate the effective use of control hardware in a system environment. These features include: Vertical mounting enables more efficient cabling, as most field cabling applications require access from the top or bottom of the system cabinet.

The analog input module is a device that collects the analog signal from the remote field to the computer. It uses the RS-485 bus as a data communication line to provide the analog to 485 function, which can simultaneously input the analog to the module and transmit it to the computer through the RS-485 bus. As the RS-485 interface is used as the communication interface, it can combine multiple modules to transmit more analog signals, and can be distributed on the 485 line, using the address code to distinguish, and can directly access the configuration software of MODBUS RTU protocol.

In the PLC, the CC-MCAR01 analog effective signal is usually represented by the analog input/output map register (AI/AQ). The analog input circuit converts the analog signal from the external input into a one-word-long digital quantity and stores it in the analog input image register area, the area identifier is AI; The analog output circuit converts the 1-word (16-bit) value of the analog output map register area into an analog current or voltage output, with the area identifier AQ. The numeric quantity in the PLC has a word length of 16 bits, that is, two bytes, so its address is expressed in even numbers, such as AIW0, AIW2...... ; AQW0, AQW2...... . Analog inputs/outputs are assigned addresses in units of 2 words (W), and each analog input/output takes 1 word (2 bytes). If there are three analog inputs, allocate four characters (AIW0, AIW2, AIW4, and AIW6). If AIW6 is not in use, it cannot be used or allocated to subsequent modules. If there is one analog output, two characters (AQW0 and AQW2) need to be assigned. The unused word AQW2 cannot be used or assigned to subsequent modules.
