AC 9OOF控制器真正扩展了自由分布控制皈关识别结果家了其高度复杂的自动化功能，AC9OOF模炔化控制器通过可插拔SD提供了扩展的灵活性卡，更多以太网端口，冗余选项对于高可用性和功率约1500使用Plus CPU (PM SO4F)时的lo标准CPU(PM O2F)或高达40Ol o时使用LiteCPU (PM 901F)。AC 900F的一个关键特点是支持SD卡。特别是新的可选显示AC 900F允许加载应用程序或固件进入控制器，无需PC或FTP软件。CPU通常支持大约1500个l/ o PM 9021 / PM 904f CPU PM 901F最多支持400个l o(Lite)。-高可用性的冗余选项。.AC 900F Plus (PM 9O4F) AC 9O0F标准(PM9O2F)4个内置以太网端口，支持Modbus TCP或60870-5-104远程控制协议.AC SOOF Lite(PM901F):三内置以太网端口支持Modbus TCP或60870-5-远程控制协议。两串口支持Modbus RTU或远程控制协议。可选PROFIBUS主模块(PM901/PM902最多两个，PM9O4F最多四个)提供集成线路冗余.可选1个CAN总线通信接口用于连接自由机架IOI/O模块的直连，包括模块组合输入和输出只是一个模块可以减少占用空间和成本。

PLC的硬件：PLC控制器本身的硬件采用积木式结构，各厂家产品结构大同小异。以日本欧姆龙C200HE为例，为总线模板框式结构，基本框架(CPU母板)上装有CPU模板，其它槽位装有I/O模板;如果I/O模板多时，可由CPU母板经I/O扩展电缆连接I/O扩展母板，在其上装I/O模板;另一种方法是配备远程I/O从站等。这些都说明了PLC厂家将硬件各部件均向用户开发，便于用户选用，配置成规模不等的PLC，而且这种硬件配置的开放性，为制造商、分销商(代理商)、系统集成商、最终用户带来很多方便，为营销供应链带来很大便利，这是一大成功经验 。lO模块也可以通过现场总线。

The AC9OOF controller truly extends the free distribution control and recognition results to its highly complex automation functions. The AC9OOF modular controller provides extended flexibility cards through pluggable SD, more Ethernet ports, and redundant options for high availability and power of about 1500 using the Lo standard CPU (PM O2F) with Plus CPU (PM SO4F) or LiteCPU (PM 901F) with up to 40Ol o. A key feature of AC 900F is its support for SD cards. Especially the new optional display AC 900F allows loading applications or firmware into the controller without the need for PC or FTP software. CPU usually supports approximately 1500 l/o PM 9021/PM 904f CPU PM 901F supports up to 400 l/o (Lite)- High availability redundancy options AC 900F Plus (PM 9O4F) AC 9O0F standard (PM9O2F) has four built-in Ethernet ports that support Modbus TCP or 60870-5-104 remote control protocol. AC SOFF Lite (PM901F): Three built-in Ethernet ports support Modbus TCP or 60870-5 remote control protocol. Two serial ports support Modbus RTU or remote control protocol. Optional PROFIBUS main modules (PM901/PM902 up to two, PM9O4F up to four) provide integrated line redundancy. Optional 1 CAN bus communication interface is used for direct connection of free rack IOI/O modules, including module combinations of input and output. Only one module can reduce footprint and cost

PLC hardware: The hardware of the PLC controller itself adopts a building block structure, and the product structures of various manufacturers are similar. Taking the Japanese Omron C200HE as an example, it has a bus template frame structure. The basic framework (CPU motherboard) is equipped with CPU templates, while other slots are equipped with I/O templates; If there are many I/O templates, the CPU motherboard can be connected to the I/O expansion motherboard through an I/O expansion cable, and I/O templates can be installed on it; Another method is to equip remote I/O slave stations, etc. These all indicate that PLC manufacturers develop hardware components for users to choose from, and configure them into PLCs of varying scales. Moreover, the openness of this hardware configuration brings a lot of convenience to manufacturers, distributors (agents), system integrators, and end users, and greatly facilitates the sales supply chain. This is a great success experience. The lO module can also be connected via fieldbus
