串行接口标准RS232422485
串行接口标准（RS232/422/485）RS-232与RS-485标准只对接口的电气特性做出规定，而不涉及接插件、电缆或协议。
一、RS-232、RS-422与RS-485的由来RS-232、RS-422与RS-485都是串行数据接口标准，最初都是由电子工业协会（EIA）制订并发布的，RS-232在1962年发布，命名为EIA-232-E，作为工业标准，以保证不同厂家产品之间的兼容。
RS-422由RS-232发展而来，它是为弥补RS-232之不足而提出的。
为改进RS-232通信距离短、速率低的缺点，RS-422定义了一种平衡通信接口，将传输速率提高到10Mb/s，传输距离延长到4000英尺（速率低于100kb/s时），并允许在一条平衡总线上连接最多10个接收器。
RS-422是一种单机发送、多机接收的单向、平衡传输规范，被命名为TIA/EIA-422-A标准。
为扩展应用范围，EIA又于1983年在RS-422基础上制定了RS-485标准，增加了多点、双向通信能力，即允许多个发送器连接到同一条总线上，同时增加了发送器的驱动能力和冲突保护特性，扩展了总线共模范围，后命名为TIA/EIA-485-A标准。
由于EIA提出的建议标准都是以“RS”作为前缀，所以在通讯工业领域，仍然习惯将上述标准以RS作前缀称谓。
RS-232、RS-422与RS-485标准只对接口的电气特性做出规定，而不涉及接插件、电缆或协议，在此基础上用户可以建立自己的高层通信协议。
因此在视频界的应用，许多厂家都建立了一套高层通信协议，或公开或厂家独家使用。
如录像机厂家中的Sony与松下对录像机的RS-422控制协议是有差异的，视频服务器上的控制协议则更多了，如Louth、Odetis协议是公开的，而ProLINK则是基于Profile上的。
二、RS-232串行接口标准目前RS-232是PC机与通信工业中应用最广泛的一种串行接口。
RS-232被定义为一种在低速率串行通讯中增加通讯距离的单端标准。

Information is transferred as a continuous 64 frames of 5 bits each. The four wires applied by RSL between a master device and a slave device, are arranged as two pairs of wires, one providing communication, the other pair providing power. All stations on the RSL are connected in parallel. The RSL master provides synchronization for the read/write data transfer.The RSL is used as a long distance (hoistway length) communication channel for fixtures and bit-oriented inputs and outputs.2.1 Communication ContextRSL is being applied as one of the communication protocols in the elevator control system communication architecture.

The RSL protocol addresses the physical and link layers, therefore they will be theonly layers described in this document.Typical use includes:• Bit-oriented input to the controller e.g. buttons, keyswitches• Bit-oriented output from the controller e.g. tell-tale lights• Position indicator data stream• Electro-luminescent Display (ELD) data4 OSI Layer 1: – RSL PhysicalFollowing a synchronization sequence, the master station transmits data for each slave station and then readsdata from the slave stations.4.1 RSL Physical layerThis section defines the signal levels, cabling and logical representation of signals for the RSL.4.1.1 Signal levelsParameter MinMaxUnit Signal voltage levels for L1 and L2 data lines -6.0 35.0 VdcCommon mode rejection voltage High level: VL1 >= VL2 + 0.8 Vdc Low level: VL1 <= VL2 + 0.3 Vdc +4.0Vdc4.1.2 Power levelsParameter MinMaxUnit Power lines 17.7 35.0 VdcVoltage drop on power distribution line 2.0 VdcCurrent - board specific4.1.3 Bit Representation4.1.3.1 Signal LevelsParameter MinMaxUnit Logical “0” -6.0 0.8 VdcLogical “1” 17.0 35.0 Vdc4.1.4 Transmission MediumThe four wire serial link consists of two data lines and two power lines.

It provides the clock pulsed, drives the output for all frames (stations/addresses) during the write cycle and reads the inputs from all frames (slave stations/addresses) during the read cycle.5.1 FramesData is transferred in ‘frames’ that are a nominally defined time of 800 µS made up of a 100 µS clock pulse and 5 data bits of 100 µS each. The data bits are bounded by 100 µS ‘dead’ slots. See reference [3].5.2 Data Cycles (Master Station driven)Each data transfer cycle consists of a three sequential sub-cycles (from the master station perspective): write, read, synchronization. See reference [3].5.2.1 Synchronization CycleThe Synchronization Cycle consists of two frames without clock pulses that are inserted between everyL2L2data write/read cycle.5.2.2 Write Cycle5.2.3 Read Cycle5.3 Frame TimingSignal Min Typ Max Unit Cycle Time 788 800 835 µS Clock Width 80 100 146 µS Data 80 100 146 µS5.4 Error DetectionThe RSL protocol supports detection of loss of synchronization. The master station monitors for bit and clock pulse errors, providing a flag on the detected error.

Each slave station/address) is responsible to read 5-bits from frame 0, the 5th bit from frames 4 – 39 (36 ‘sdata’ bits related to PI information) and the 5 bits associated with its address.

西门子PLC几种常见的连接口和通讯协议
西门子PLC几种常见的连接口和通讯协议第一个大问题：RS232接口与RS485接口的区别一、接口的物理结构1、RS232接口：计算机通讯接口之一，通常 RS-232 接口以9个引脚 (DB-9) 或是25个引脚 (DB-25) 的型态出现，一般个人计算机上会有两组 RS-232 接口，分别称为 COM1 和 COM2。
2、RS485RS485无具体的物理形状，根据工程的实际情况而采用的接口。
二、接口的电子特性1、RS232：传输电平信号接口的信号电平值较高(信号“1”为“-3V至-15V”,信号“0”为“3至15V”)，易损坏接口电路的芯片，又因为与TTL电平(0~“<0.8v”,1~“>2.0V”)不兼容故需使用电平转换电路方能与TTL电路连接。
另外抗干扰能力差。
2、RS485：传输差分信号逻辑“1”以两线间的电压差为+（2—6）V表示；逻辑“0”以两线间的电压差为-（2—6）V表示。
接口信号电平比RS-232降低了，就不易损坏接口电路的芯片，且该电平与TTL电平兼容，可方便与TTL电路连接。
三、通讯距离长短1、RS232：RS232传输距离有限，最大传输距离标准值为15米，且只能点对点通讯，最大传输速率最大为20kB/s。
2、RS485：RS485最大无线传输距离为1200米。
最大传输速率为10Mbps，在100Kb/S的传输速率下，才可以达到最大的通信距离。
采用阻抗匹配、低衰减的专用电缆可以达到1800米！超过1200米，可加中继器（最多8只），这样传输距离接近10Km。
四、能否支持多点通讯RS232：RS232接口在总线上只允许连接1个收发器，不能支持多站收发能力，所以只能点对点通信，不支持多点通讯。
RS485：RS485接口在总线上是允许连接多达128个收发器。
即具有多站通讯能力，这样用户可以利用单一的RS485接口方便地建立起设备网络。
五、通讯线的差别RS232：可以采用三芯双绞线、三芯屏蔽线等。

OTIS通信协议
RSL由主控板(LCB_II)和最多60个RS节点（也就是RS5,RS18等电路板）组成。
两个链接（轿厢和厅站链）都必须由终端板(LT1)端接。
每个RS节点支持4对独立的输入/输出点E1~E8)，另外还可以连接一个位置（层楼）指示器(E9~E11)。
RSL可以通过服务工具在LCBII的EEPROM中配置。
RSL串行总线由时钟和数据线（L1 ，L2 ）和电源线组成（30VDC，接地）。
)
RSL数据帧有128个时钟周期，分为写和读两个部分。
时钟周期4-63和68-127分别对应RS节点的地址4-63，节点地址通过板上6位拨动开关设置。
时钟周期0-3和64-67用于同步帧和发布写/读操作命令。
请参考附图。
在每个时钟周期中总线可传输5个数据位。
在上半个“写入“帧中，每个时钟周期前4个数据位对应于相应RS节点E1~E4输出，时钟周期4-41的第5个数据位组成了层楼信息，每个RS节点可以转化并驱动相连接的层楼指示器（如有的话，例如RS18）。
在下半个“读取“帧中，每个时钟周期前4个数据位对应于相应RS节点E5~E8输入点，第五位是个校验位。

几种串行通信接口标准
几种串行通信接口标准在数据通信、计算机网络以及分布式工业控制系统中，经常采用串行通信来交换数据和信息。
1969年，美国电子工业协会(EIA)公布了RS-232C作为串行通信接口的电气标准，该标准定义了数据终端设备(DTE)和数据通信设备(DCE)间按位串行传输的接口信息，合理安排了接口的电气信号和机械要求，在世界范围内得到了广泛的应用。
但它采用单端驱动非差分接收电路，因而存在着传输距离不太远(最大传输距离15m)和传送速率不太高(最大位速率为20Kb/s)的问题。
远距离串行通信必须使用Modem，增加了成本。
在分布式控制系统和工业局部网络中，传输距离常介于近距离(＜20m)和远距离(＞2km)之间的情况，这时RS-232C（25脚连接器)不能采用，用Modem又不经济，因而需要制定新的串行通信接口标准。
1977年EIA制定了RS-449。
它除了保留与RS-232C兼容的特点外，还在提高传输速率，增加传输距离及改进电气特性等方面作了很大努力，并增加了10个控制信号。
与RS-449同时推出的还有RS-422和RS-423，它们是RS-449的标准子集。
另外，还有RS-485，它是RS-422的变形。
RS-422、RS-423是全双工的，而RS-485是半双工的。
RS-422标准规定采用平衡驱动差分接收电路，提高了数据传输速率(最大位速率为10Mb/s)，增加了传输距离(最大传输距离1200m)。
RS-423标准规定采用单端驱动差分接收电路，其电气性能与RS-232C几乎相同，并设计成可连接RS-232C和RS-422。
它一端可与RS-422连接，另一端则可与RS-232C连接，提供了一种从旧技术到新技术过渡的手段。
同时又提高位速率(最大为300Kb/s)和传输距离(最大为600m)。
因RS-485为半双工的，当用于多站互连时可节省信号线，便于高速、远距离传送。
许多智能仪器设备均配有RS-485总线接口，将它们联网也十分方便。
