Ethernet进入工业控制领域的另一个主要问题是,它所用的接插件、集线器、交换机和电缆等均是为商用领域设计的,而未针对较恶劣的工业现场环境来设计(如冗余直流电源输入、高温、低温、防尘等),故商用网络产品不能应用在有较高可靠性要求的恶劣工业现场环境中。 随着网络技术的发展,上述问题正在迅速得到解决。为了解决在不间断的工业应用领域,在极端条件下网络也能稳定工作的问题,美国Synergetic微系统公司和德国Hirschmann、Jetter AG等公司开发和生产了导轨式集线器、交换机产品,安装在标准DIN导轨上,并有冗余电源供电,接插件采用牢固的DB-9结构。台湾四零四科技(Moxa Technologies)在2002年6月推出工业以太网产品—MOXA EtherDevice Server(工业以太网设备服务器),特别设计用于连接工业应用中具有以太网络接口的工业设备(如 PLC、HMI、DCS系统等)。 近刚刚发布的IEEE802.3af标准中,对Ethernet的总线供电规范也进行了定义。此外,在实际应用中,主干网可采用光纤传输,现场设备的连接则可采用双绞线,对于重要的网段还可采用冗余网络技术,以此提高网络的抗干扰能力和可靠性。

三极管,全称半导体三极管,也称双极型晶体管、晶体三极管,是一种控制电流的半导体器件其作用是把微弱信号放大成幅度值较大的电信号,也用作无触点开关。三极管,是半导体基本元器件之一,具有电流放大作用,是电子电路的核心元件。三极管是在一块半导体基片上制作两个相距很近的PN结,两个PN结把整块半导体分成三部分,中间部分是基区,两侧部分是发射区和集电区,排列方式有PNP和NPN两种。发射区和基区之间的PN结叫发射结,集电区和基区之间的PN结叫集电结。
