LOGO!Learn Advanced
Introduction
The LOGO!Learn – Advanced Training Kit is specially designed to match the features of the new LOGO! 0BA6 generation. It is mounted on a stable aluminum base. Eight push/latch buttons (4 of which are debounced) are available for signal inputs as well as 4 potentiometers for voltage setting (0 to 10 V) for analog value inputs. The signal output (status) is indicated by 4 LEDs (5 mm). In addition, you can connect external simulators (e.g., motor controller, traffic light, etc.) via a 24-pin interface plug connector. Four sliding switches on the board switch the digital inputs (I1, I2, I7 and I8) to analog inputs. The "IR receiver" sliding switch switches input I3 to IR receiving. This allows you to implement 10 different switching states on the LOGO! via the IR remote control. The "proximity simulation" sliding switch activates input I4. This allows a frequency of 60 Hz to 5 KHz to be linearly set via the potentiometer and fed to the LOGO! for internal processing.
When the "signal encoder on/off" sliding switch is switched on or off, the acoustic signal encoder (i.e., buzzer/beeper) is also switched on or off as necessary. Expansion modules (e.g., Pt100 module, etc.) can be plugged into the LOGO! Learn Advanced and mechanically locked via the 8-pin socket strip. The LOGO! TD can be connected to the "Display" terminal. The small LOGO! controller (version: 0BA6) is mounted on the training PCB in accordance with industrial standards. It can be installed or removed at all times with a screwdriver.
The exercises sequences are arranged from "beginner to advanced" and are printed on 32 learning cards which can be easily rearranged as necessary.

Attention:
?Only an operating voltage of 12/24V DC should be connected to LOGO! Learn Advanced
?If the inputs I1, I2, I7 or I8 are used for analog signals, the related sliding switches AI1 to AI4 have to be switched to position “A” (analog) otherwise
they must be in “D” position for “digital”. If the analog inputs are used (switch in “analog” position) the related digital inputs will be inactive and the analog
inputs will be switched to active. The potentiometers A1 to A4 can then be
used.
?External inputs and outputs can be added via the interface connector.
?Please note that 24V DC should not be exceeded on the external interface connector. Any excess voltage will damage the device. If external analog
signals 0-10V DC are fed into the LOGO! (I1, I2, I7 or I8), the sliding switches have to be set to “digital“. In that case no switches on the board (switches 1-8) should be activated (all switches to be set to “0” in the middle position) ?Inputs I3 to I6 can be used for fast counting inputs (up to 5 KHz). It is thus possible to determine, for example, the exact position of an object on a
conveyor belt
Models of conveyor belts for this application are available from IKH - Didaktische Systeme.
Please ask for our general catalogue on a CD or on paper.
Suggestions are always welcome.
LOGO!Learn Basis
Introduction
The LOGO!Learn – Basic training kit is mounted on a sturdy aluminium frame.
For the signal inputs there are 8 push-button/switches provided as well as 2 potentiometers for analog inputs. Furthermore, it is possible to connect external simulators via the 14-pin interface-connector. The signal output (state) is indicated by 4 Light Emitting Diodes (LED 5mm). Two sliding switches on the board enable the switch-over from digital inputs (I7+I8) to analog inputs (0…10V). The exercises are based on the principle of increasing difficulty and are printed on 32 learning cards. These cards are interchangeable as required.

1 Mains adapter 230V AC / 12V DC 500 mA
32 Learning cards (practical examples) with solutions on a CD-ROM
Attention:
?Only an operating voltage of 12V DC should be connected to LOGO!Learn - Basic
?If all 8 inputs are used, the sliding switches I7 and I8 have to be switched to the “digital” position. If the analog inputs I7 or I8 are used (“analog” switch
position) the digital inputs 7 or 8 will be inactive and the analog inputs will be switched to active. The potentiometers A1 and A2 respectively can then be
used.
?External inputs and outputs can be added via the interface connector.
?Please note that 12V DC should not be exceeded on the interface connector.
Any excess voltage will ruin the instrument. If external analog signals 0-10V
DC are fed into the instrument (I7 or I8) via the external interface, the sliding
switches have to be set to “digital”. In this case, the switches on the board
(switches 1-8) should be deactivated (all switches to be set to “0”)
Inputs I5 and I6 can be used for fast counting inputs (up to 2 KHz) for the LOGO! versions -0BA5. It is thus possible to determine, for example, the exact position of an object on a conveyor belt.
Models of conveyor belts for this application are available from IKH - Didaktische Systeme.

第一章 S7-300/400的基本结构 1、 S7-300/400属于模块式PLC，主要由机架、CPU模块、信号模块、功能模块、接口模块、通信处理器、电源模块和编程设备（工程师、操作员站和操作屏）组成。 图1-1 PLC控制系统示意图 PLC的主要生产厂家：德国的西门子(Siemens)公司，美国Rockwell公司所属的AB公司，GE-Fanuc公司，法国的施耐德(Schneider)公司，日本的三菱和欧姆龙(OMRON)公司。PLC的工作过程 表1-1 逻辑运算关系表 与或非 Q4.0=I0.0*I0.1 Q4.1 = I0.2+I0.3 Q4.2 =/I0.4 I0.0 I0.1 Q4.0 I0.2 I0.3 Q4.1 I0.4 Q4.2 0 0 0 0 0 0 0 1 0 1 0 0 1 1 1 0 1 0 0 1 0 1 1 1 1 1 1 1 在CPU模块上有存储器(用来存放系统程序、用户程序、逻辑变量和其它一些信息)，包括ROM和RAM。可通过扩展槽扩展用户RAM。 l RAM：主程序区OB1+子程序区（FB、FCB、定时中断块等）断电时由锂电池供电（几年）以免RAM中信息丢失。锂电池电压< 规定值，灯报警，换电池（期间靠电容充电几分钟）。 l PLC采用循环执行用户程序的方式。 OB1是用于循环处理的组织块（主程序），它可以调用别的逻辑块，或被中断程序（组织块）中断。在起动完成后，不断地循环调用OB1，在OB1中可以调用其它逻辑块(FB, SFB, FC 或SFC)。 循环程序处理过程可以被某些事件中断。 在循环程序处理过程中，CPU并不直接访问I/O模块中的输入地址区和输出地址区，而是访问CPU内部的输入/输出过程映像区。批量输入、批量输出。 梯形图中Q4.0的线圈（称为内部线圈）“通电”时，对应的输出过程映像位为1状态。信号经输出模块隔离和功率放大后，继电器型输出模块中对应的硬件继电器的线圈（外部线圈）通电，其常开触点闭合，使外部负载通电工作。 外部输入电路接通时，对应的输入过程映像位(例如I0.0)为1状态，梯形图中对应的输入位的常开触点接通，常闭触点断开。 某一编程元件对应的过程映像位为1状态时，称该编程元件为ON，过程映像位为0状态时，称该编程元件为OFF。 循环时间（Cycle time）: 是指操作系统执行一次图1-4所示的循环操作所需的时间，又称为扫描循环时间（Scan Cycle Time）或扫描周期。如0.7ms、1.7ms等 l 性能指标： I/O点数、扫描周期、指令数目、功能模块多少、
