General Description The MAX3483, MAX3485, MAX3486, MAX3488,MAX3490, and MAX3491 are 3.3V , low-power transceivers forRS-485 and RS-422 communication. Each part containsone driver and one receiver. The MAX3483 and MAX3488feature slew-rate-limited drivers that minimize EMI andreduce reflections caused by improperly terminatedcables, allowing error-free data transmission at data ratesup to 250kbps. The partially slew-rate-limited MAX3486transmits up to 2.5Mbps. The MAX3485, MAX3490, andMAX3491 transmit at up to 10Mbps.Drivers are short-circuit current-limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature thatguarantees a logic-high output if both inputs are opencircuit.The MAX3488, MAX3490, and MAX3491 feature full-duplex communication, while the MAX3483, MAX3485, andMAX3486 are designed for half-duplex communication.Applications ●Low-Power RS-485/RS-422 Transceivers ●Telecommunications ●Transceivers for EMI-Sensitive Applications ●Industrial-Control Local Area NetworksFeatures●Operate from a Single 3.3V Supply—No Charge Pump!●Interoperable with +5V Logic ●8ns Max Skew (MAX3485/MAX3490/MAX3491)●Slew-Rate Limited for Errorless Data Transmission (MAX3483/MAX3488)●2nA Low-Current Shutdown Mode (MAX3483/MAX3485/MAX3486/MAX3491)●-7V to +12V Common-Mode Input Voltage Range ●Allows up to 32 Transceivers on the Bus ●Full-Duplex and Half-Duplex Versions Available ●Industry Standard 75176 Pinout (MAX3483/MAX3485/MAX3486)●Current-Limiting and Thermal Shutdown for Driver Overload Protection 19-0333; Rev 1; 5/19Ordering Information continued at end of data sheet.*Contact factory for for dice specifications.PARTTEMP .

PLC和西门子MICROMASTER 420变频器通讯详解一、西门子变频器通讯协议介绍西门子变频器采纳西门子的USS通讯协议,依据西门子变频器说明书与通讯有关的主要参数如下:P0003:=3用户访问级(专家级)P0700:=5 选择命令源(通过COM 链路的USS 设置)P1000:=5 频率设定值的选择(通过COM 链路的USS 设定)P2023:=1 USS 规格化,使能规格化假如P2023 设置为1,数值是以肯定十进制数的形式发送,即4000(十进制)(=0FA0hex)等于40.00Hz。
P2023:=6 USS 波特率(9600 波特)P2023:=1 USS 地址,为变频器指定一个唯一的串行通讯地址。
P2023:=2 USS 协议的PZD (过程数据)长度(这个长度和R2023数据有关)P2023:=127 USS 协议的PKW 长度,可变长度二、通讯报文的结构每条报文都是以字符STX(=02hex)开头,接着是长度的说明(LGE)和地址字节(ADR)。
然后是采纳的数据字符。
报文以数据块的检验符(BCC)结束。
STX LGE ADR 1 2 … ……. N BCC|采纳的数据字符|这种通讯结构是变频器自己定义的数据格式,类似于仪表通讯,国产plc与这样的格式通讯一般是AXCII通讯或者自由口通讯,也就是自己根据通讯格式组织针通讯。
三、报文写入数据定义系统默认写入数据在R2023的【0】、【1】、【2】、【3】都有定义,可以修改成自己想要的地址。
四、报文读取数据定义系统默认PLC读回数据在R2023的【0】、【1】、【2】、【3】都有定义,可以修改成自己想要的地址。
通过修改R2023和R2023内部地址,就可以根据使用需求进行PLC 和西门子MICROMASTER 420变频器数据交换了。
四、PLC和西门子MICROMASTER 420变频器通讯程序案例这个是通过永宏PLC通讯读取变频器的模拟量采集数据,里面没有备注,图一和图二接起来就是,认真看是能看明白的。

Standard feature include digital signal filtering with a time constant adjustable from 0 to 25 sec, selectable last-digit rounding of 1, 2, 5, 10, 20 and 50, and 10-point custom curve linear-ization.Viewing distances up to 320 feet (100 m) are achieved with oversize digits. A rule of thumb is that viewing distance in feet is 40 times digit height in inches, or in metric terms, that viewing distance in meters is digit height in millimeters divided by 2. Four digit heights are available: 57 mm (2-1/4"), 102 mm (4.0"), 150 mm (5.9"), and 200 mm (7.9"). Solid segments are used for normal brightness 2.2" and 4.0" digits. Individual 5 mm LED pixels are used for larger digits and outdoor brightness versions. The number of digits can be 4 or 6.Indoor or Outdoor Viewing: MAGNA Series Displays with normal brightness LEDs can beread across an entire plant floor to keep workers informed without leaving their work area. Displays with outdoor brightness LEDs can be read across an industrial yard, parking lot or roadway, for example to display vehicle load. Available mounting options are panel mount, wall mount and suspen-sion mount.Environmental sealing to IP65 (NEMA-4X) is standard. Available Options are dual 5A relays,an analog output, an RS-232 or RS485 serial data output, and 95-264 Vac or 11-30 Vdc power. Intuitive Setup is normally provided by means of built-in front panel switches, which can be locked. It is also possible to remotely wire four pushbuttons to the display.SpecificationsApprovalsTypes Produced to IPC 610 Class 2 StandardUL ISO9001:2008 QAStrain Gauge / Load Cell InputA/D Converter Signal Gain Input Resistance Accuracy Tempco, Scale Tempco, Offset Excitation Output 20-bit resolutionSuitable for 0.5 mV / V to 4 mV / V load cells> 10 MΩ± 0.05% of range.± 25 ppm/°C± 30 ppm/°CIsolated 10V up to 120 mA to power up to four 350Ω load cells in parallelDisplayNumber of Digits Digit HeightDigit Color BrightnessNumeric Format Display Update Rate 4 or 657 mm (2-1/4"), 102 mm (4.0"), 150 mm (5.9"), or 200 mm (7.9") RedVariable8.8.8.8. or 8.8.8.8.8.8.10 readings/secondUser ControlsScaling Filtering Rounding Linearization Digital direct or theoretical scaling with scale & offset.

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 TransceiversThe major difference between tests done using the Human Body Model and IEC1000-4-2 is higher peak current in IEC1000-4-2, because series resistance is lower in the IEC1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC1000-4-2 is generally lower than that measured using the Human Body Model. Figure 7 shows the current waveform for the 8kV IEC1000-4-2 ESD contact-discharge test.The air-gap test involves approaching the device with a charged probe. The contact-discharge method connects the probe to the device before the probe is energized.Machine Model The Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protec-tion during manufacturing—not just inputs and outputs. Therefore,after PC board assembly,the Machine Model is less relevant to I/O ports.MAX487E/MAX1487E:128 Transceivers on the Bus The 48kΩ, 1/4-unit-load receiver input impedance of the MAX487E and MAX1487E allows up to 128 transceivers on a bus, compared to the 1-unit load (12kΩinput impedance) of standard RS-485 drivers (32 transceivers maximum). Any combination of MAX487E/MAX1487E and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481E, MAX483E, MAX485E, and MAX488E–MAX491E have standard 12kΩreceiver input impedance.MAX483E/MAX487E/MAX488E/MAX489E:Reduced EMI and Reflections The MAX483E and MAX487E–MAX489E are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. F igure 16 shows the driver output waveform and its Fourier analy-sis of a 150kHz signal transmitted by a MAX481E, MAX485E, MAX490E, MAX491E, or MAX1487E. High-frequency harmonics with large amplitudes are evident.F igure 17 shows the same information displayed for a MAX483E, MAX487E, MAX488E, or MAX489E transmit-ting under the same conditions. F igure 17’s high-fre-quency harmonics have much lower amplitudes, and the potential for EMI is significantly reduced.Low-Power Shutdown Mode(MAX481E/MAX483E/MAX487E) A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled. In shutdown, the devices typically draw only 0.5µA of supply current.RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.F or the MAX481E, MAX483E, and MAX487E, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485E, MAX488E–MAX491E, and MAX1487E can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics).Figure 16.

512位读/写多用途非接触式识别装置译者:杭州电子科技大学杨四郎QQ10416823432013 /04 /07概述EM4205/4305是CMOS集成电路,主要用于电子射频读写应答器,它适用于低代价的动物标签应用的解决方案。
这款芯片的通信协议与EM4469/4569系列兼容。
EM4205与EM4305最主要的区别如下:◆EM4305为两个线圈输入增大了凸起的焊盘,EM4305的这个加大的凸起焊盘用于直接与天线相连,从而避免了需要使用一个模块。
◆EM4305提供了一个330p的谐振电容。
这款芯片通过外部线圈与内部集成电容一起组成的谐振电路,从连续的125kHz磁场中获取能量启动。
芯片从内部的EEPROM 中读出数据,并通过与线圈并联的负载电阻的开断产生深幅调制,将数据发送出去。
通过对125kHz磁场的幅度调制,可以执行各种命令并更新EEPROM中的数据。
EM4205/4305支持双相编码和曼彻斯特编码。
EM4205/4305的运行模式储存在EEPROM 的配置字中。
通过设置保护位,所有的EEPROM字都可以被写保护。
这款芯片包含了工厂编程的32位唯一识别码(UID)。
