61C22B RELIANCE 远程磁头通信端口

部件号:61C22B

制造商:信实电气

系列:自动最大PLC

61C22B是信实电气制造的本地I/O头。它也可能是由Asea Brown Boveri和Baldor Reliance出售的。

61C22B是专为AutoMax DCS 上的轨道I/O系统创建的轨道安装式数字本地磁头。当在轨道式IV/O系统中使用时，允许定制以满足系统要求。四个不同的数字V/0能够与设备上的单个V/O端口通信。然后，可以连接到远程)O头的数字/O数星可以从64个增加到256个。该模块还预装了自己的电源，能够为四个数字V/O模块的总电源轨供电。

61C22B的面板上有很多组件。它有一个250VAC MDQ4安培可更换保险丝室。它有一组LED指示灯，标记为电源、COM、轨道故障0、轨道故障1、轨道故障⒉和轨道故障3。有五个12点公头端口标记为RAILO、RAL1、RAIL2、RAL3和INPUT。其中四个端口是IV/O通信端口，最后一个是远程磁头通信端口。

61C22B的背面有一个安装支架，可用于将模块放在机架组件上。该模块的顶部和侧面都有工厂钻孔。这些孔对模块至关重要，因为它们允许空气流入模块的内部电路。

I/O系统是指进行输入/输出数据处理的系统，它主要由外部设备、接口部件、总线、相应的管理软件和I/O软件组成。

I/O系统的特性：

接口部件：一种为主机和外设之间传送信息而设置的硬件线路，在系统总线和外设之间传输信号，提供缓冲作用，以满足接口两边的时序要求。

统一编址方式：把I/O端口当做存储器的单元进行地址分配。

61C22B 桌面操作系统与RTOS相比，另一个差别就是对于稳定、可靠方面的设计思路。一方面，桌面操作系统比较庞大、复杂，而RTOS比较小巧、简捷，而;越简单、越可靠，越复杂、故障概率越大这又是一个常理。另一方面，重要的是:桌面操作环境与嵌入式环境在设计思路上有一个重大的不同——桌面环境定应用软件与操作系统相比而言可以是不可靠的，而嵌入式环境定应用软件与操作系统—样可靠。

运行于嵌入式环境中的RTOS要求应用软件具有与操作系统同样的可靠，这种设计思路对应用开发提出了高的要求，同时也要求操作系统自身足够开放。

Part number :61C22B

Manufacturer: Reliance Electric

Series: Automatic maximum PLC

The 61C22B is a local I/O head manufactured by Reliance Electric. It may also have been sold by Asea Brown Boveri and Baldor Reliance.

The 61C22B is a track-mounted digital local head created specifically for track I/O systems on AutoMax DCS. When used in orbital IV/O systems, customization is allowed to meet system requirements. Four different digital V/ 0s are able to communicate with a single V/O port on the device. Then, the number /O number stars that can be connected to the remote O head can be increased from 64 to 256. The module also comes pre-installed with its own power supply, capable of powering the main power rail of the four digital V/O modules.

There are many components on the 61C22B panel. It has a 250VAC MDQ4 amp replaceable fuse room. It has a set of LED indicators labeled Power, COM, Track fault 0, track fault 1, track fault ⒉, and track fault 3. There are five 12-point male ports labeled RAILO, RAL1, RAIL2, RAL3, and INPUT. Four of the ports are IV/O communication ports and the last one is remote head communication port.

The 61C22B has a mounting bracket on the back that can be used to place the module on the rack assembly. The module has factory drill holes on the top and sides. These holes are crucial to the module because they allow air to flow into the module's internal circuitry.

I/O system refers to the input/output data processing system, which is mainly composed of external devices, interface components, buses, corresponding management software and I/O software.

I/O system features:

Interface unit: A hardware line for transmitting information between the host and peripherals, transmitting signals between the system bus and peripherals to provide buffering to meet the timing requirements on both sides of the interface.

Unified addressing mode: The I/O port is used as a memory unit for address allocation.

Another difference between 61C22B desktop operating system and RTOS is the design idea of stability and reliability. On the one hand, the desktop operating system is relatively large and complex, while the RTOS is relatively small and simple. The simpler, the more reliable, the more complex, the greater the probability of failure. On the other hand, it is important to note that there is a major difference in design thinking between the desktop operating environment and the embedded environment - the desktop application software can be unreliable compared to the operating system, while the embedded application software is as reliable as the operating system.

RTOS running in embedded environment requires the application software to have the same reliability as the operating system, this design idea puts forward high requirements for application development, but also requires the operating system itself to be open enough.
