RTU转换数据采集终端基本概念RTU（远程终端单元），英文全称RemoteTerminalUnit，中文全称为远程终端控制系统，负责对现场信号、工业设备的监测和控制。
RTU(RemoteTerminalUnit)是构成企业综合自动化系统的核心装置，通常由信号输入/出模块、微处理器、有线/无线通讯设备、电源及外壳等组成，由微处理器控制，并支持网络系统。
它通过自身的软件(或智能软件)系统，可理想地实现企业中央监控与调度系统对生产现场一次仪表的遥测、遥控、遥信和遥调等功能。
特点RTU，是SCADA系统的基本组成单元。
RTU是安装在远程现场的电子设备，用来监视和测量安装在远程现场的传感器和设备，负责对现场信号、工业设备的监测和控制。
RTU将测得的状态或信号转换成可在通信媒体上发送的数据格式，它还将从中央计算机发送来得数据转换成命令，实现对设备的功能控制。
RTU通常可以分为2种基本类型——“单板RTU”和“模块RTU”。
“单板RTU”在一个版子中集中了所有的I/O接口.“模块RTU”有一个单独的CPU模块，同时也可以有其他的附加模块，通常这些附加模块是通过加入一个通用的“backplane”来实现的（像在PC机的主板上插入附加板卡一样）。
RTU是一种耐用的现场智能处理器，它支持SCADA控制中心与现场器件间的通讯。
它是一个独立的数据获取与控制单元。
它的作用是在远端控制控制现场设备，获得设备数据，并将数据传给SCADA系统的调度中心。
至少应具备以下功能：现场信号及工业设备的监测、控制与报警。
例如：数据采集及处理、现场控制、数据传输（网络通信）、现场及远程报警等等；某些RTU还具备流量累计等一系列针对特定应用领域的计量功能等等。
由于RTU是专用的器件，现在还没有统一的标准，尤其是在通讯方面，通常情况下一个产家的RTU是不能和另一个产家的RTU混用的。
协议的转化和竞争已经形成了一个产业。
近期中国自动化学会专家咨询委员会将向市场发布RTU的通用标准，这些标准大致包括如下：通信标准DNPs和IEC870。

IntroductionFigure 1-1 ACS-20B(W)-MRTU application architecture The No-touch Infrared Sensor Switch from ICP DAS can be used to open a door using palm induction, which makes it more convenient when entering or exiting a room or building. The inductive distance and the delay time for door opening are adjustable, and has red and blue indicator lights to show the status of the switch. As people enter and exit the door using the No-touch Infrared Sensor Switches, a time stamp recording the action can be simultaneously logged.The No-touch Infrared Sensor Switch includes an RS-485 interface and provides Modbus RTU communication, which can remotely enable/disable the switch and get the induction time records by the access control system.Additionally, the No-touch Infrared Sensor Switch is not only used for the access control system but also helps you control other electronic devices. While it is triggered in toggle mode at the first time, the switch outputs ON signal, and next time outputs OFF signal.The No-touch Infrared Sensor Switch can be used with electric doors to prevent issues related to the spread of infectious bacteria via touch. The switches can be used in medical institutions, retail stores, the food industry, industrial plants, and offices, etc. to provide an excellent sanitary environment.1.1 Features◼[ACS-20B-MRTU / ACS-20W-MRTU]◆Special infrared code to against interference◆Multiple operating modes: Sensing/Standby, Lock, Toggle Switch.◆Provides 8 locked periods each day◆Double-color status indicator◆Induction distance: 1 ~ 12 cm◆With Relay (N.C. and N.O. output)◆Relay hold time: 0.5 ~ 20 sec◆The switches time recording: 1,600 records◆Communication interface and protocol: RS-485/Modbus RTU◼[Applications]◆ Surveillance system◆ Home and building automation◆Medical institutions◆Retail stores◆Food industry2.

In this mode, sense the ACS-20B(W)-MRTU by hand once, the circular red LED is changed to blue (Relay: NO & COM contact). Then, sense the ACS-20B(W)-MRTU by hand once again, the blue LED will be changed back to red.

Refer to chapter 5 for related Modbus register and command.Figure 4-7: Set inversion of Red/Blue LED.4.7 Set RTCThere is built-in RTC (Real Time Clock) in ACS-20B(W)-MRTU. One RTC Time (Year/Month/Day, Hour:Minute:Second) is recorded when IR sensing by palm of hand.I n the “Set RTC” section(figure 4-8) of the utility, the time following the “System Time” radio button is the host system time. Customize the t ime by clicking the “Custom Time” radio button. Click the “Set” button to set RTC with the tiime folowing the selected radio button. Refer to chapter 5 for the related Modbus command to access RTC.Figure 4-8: Set RTC4.8 Set IR Sensing Record ModeThe “Record Mode” in the “IR Sensing Records in Storage ” section (figure 4-9) is for setting the storage mode when the storage is full. There are two modes:Mode 0 (Store from start): (default) Clear all records and store from start. Mode 1 (Discard the latest): Discard new data and keep 1600 records of old data.Figure 4-9: Set IR sensing record mode.4.9 Set Locked PeriodsLocked periods can be set in the “Locked Periods Settings” section of the utility as shown in figure 4-10. The module goes into locked mode (no IR sensing) in the locked period.Figure 4-10: Set locked periods.◆♦⌧⍓(1) Check/Uncheck “Enabled Locked Periods Function” checkbox to enable/disable thisfunction.(2) C lick the “Locked Periods” combobox to select 8 periods (0 ~ 7) for setting. The “EndTime” should be more than the “Start Time”.(3) C lick “Enable Every Day Mode” or “Enable Week Day Mode” radio button for “Every DayMode” or “Week Day Mode”.(4) This combobox can set the locked periods for every day and weekdays (Sunday toSaturday) by checking or unchecking the P0 ~ P7 checkboxes to enable or disable them.(5) Click the righ t “Set” button to finish the setting.4.10 Access All SettingsSeparate settings can be set as previous sections. Or click Menu [Settings]=>[Download All Settings to the ACS-20-MRTU] to set all settings to the module at once after all parameters are selected in the utility.Click Menu [Settings]=>[Load All Settings from the ACS-20-MRTU] to read back all settings to utility from the module at once.Figure 4-11: Access all setting of the module.4.11 Configuration FileAll settings in the utility can be saved to a configuration file by clicking Menu [File]=>[Save Settings to File(*.dat)] where the file extension is dat.Load all setting from a configuration file by clicking Menu [File]=>[Load Settings from File(*.dat)]Figure 4-12: Access configuration file.5. Modbus CommandThe following Function Code commands () are provided for a Modbus master to configure ACS-20B(W)-MRTU. FC3, FC4, and FC6 are the standard Modbus commands for Modbus masters to access the Modbus registers. Sub-FC commands of FC100 are manufacturer assigned commands for parameter settings on the module.Table 5-1: Modbus Function Code for ACS-20B(W)-MRTU5.1 Modbus Register TablePlease refer to table 5-2 and table 5-3 for the Modbus Input Registers (3xxxx) and Modbus Holding Registers (4xxxx). Settings written to the Modbus holding registers are all volatile for ACS-20B(W)-MRTU. The values will go back to the default or previous ones after power cycling. The settings can be kept (non-volatile) by the FC100 commands in section 5.2.5.1.1 Modbus Input RegistersThe Modbus Input Registers are listed in Table 5-2. They are read-only registers.Table 5-2: Modbus Input Registers (3xxxx)5.1.2 Modbus Holding RegistersThe Modbus Holding Registers are listed in Table 5-3. The access is read and write. Write values to the holding registers can change settings immediately but restore to previous ones after power cycling the module.Table 5-3: Modbus Holding Registers (4xxxx)5.2 Modbus FC100 CommandsThis section describes all sub function calls (sub-FC) of FC100 (0x64) for the settings on ACS-20B(W)-MRTU. All sub-FCs are listed in table 5-4. All setting values are non-volatile (effective after power-cycling the module). In the following sections, Modbus requests and responses are listed without CRC16 bytes.Table 5-4: Sub-FCs of FC1005.2.1 Sub-FC00 (0x00): Get the Module NameThe request/response for getting the module name is listed in table 5-5 and table 5-6.Table 5-5: FC100-Sub-FC00 RequestTable 5-6: FC100-Sub-FC00 Response5.2.2 Sub-FC04 (0x04): Set the Modbus Unit ID (Net ID)Table 5-7: FC100-Sub-FC04 RequestTable 5-8: FC100-Sub-FC04 ResponseNote: This parameter setting is effective after power cycling the module,5.2.3 Sub-FC05 (0x05): Get Communication SettingsTable 5-9: FC100-Sub-FC05 RequestTable 5-10: FC100-Sub-FC05 Response5.2.4 Sub-FC06 (0x06): Set Communication SettingsTable 5-11: FC100-Sub-FC06 RequestTable 5-12: FC100-Sub-FC06 Response5.2.5 Sub-FC07 (0x07): Read Current Communication SettingsThe settings read from Sub-FC05 is the settings by Sub-FC06 if the Byte 09 [Change Setting] of Sub-FC06 is 0 (The settings are effective after power-cycling).
