SINAMICS G120C, frame sizes FSAA to FSF, with Inligent Operator Panel IOP
SINAMICS G120C compact inverters offer a well-balanced combination of features to address a wide range of applications. They are compact, rugged devices that are easy to operate and can be optionally equipped with a basic or advanced operator panel.
SINAMICS G120C inverters are especially suitable when it comes to meeting the requirements of system integrators, OEMs and distributors regarding high productivity and tailored performance.
SINAMICS G120C is a compact converter for control cabinet mounting in IP20 degree of protection where the Control Unit (CU) and Power Module (PM) function units are combined in one device.
The compact mechanical design and the high power density allow these devices to be installed in machine control enclosures and control cabinets for maximum space utilization. The SINAMICS G120C compact converter can be butt-mounted directly, without derating at temperatures up to 40 °C (104 °F).
SINAMICS G120C, frame size FSAA with BOP-2
SINAMICS G120C can be integrated into the widest range of applications, either using the integrated digital and analog inputs or via the integrated fieldbus interface (available in USS, Modbus RTU, PROFIBUS, PROFINET / EtherNet/IP versions). Especially the product versions with integrated PROFIBUS/PROFINET interface make full integration into the Siemens TIA family possible, therefore allowing the advantages of the seamless TIA product family to be fully utilized. SINAMICS G120C devices are preset in the factory so that they can be immediay connected to PROFIBUS and/or PROFINET fieldbus systems without parameterization.
SINAMICS G120C is also equipped with the safety function STO (Safe Torque Off) as standard, which is used to safely stop drives. As a consequence, machine manufacturers can simply comply with current machinery directives with minimum associated costs.
SINAMICS G120C can control asynchronous (induction) motors in the power range from 0.37 kW up to 132 kW (0.5 hp to 200 hp). Reliable and efficient motor operation is achieved by using state-of-the-art IGBT technology combined with vector control. The extensive range of functions integrated in the SINAMICS G120C also offers a high degree of protection for the converter and motor.
Line-side components
Line reactors
Line reactors smooth the current drawn by the converter and thus reduce harmonic components in the line current. Through the reduction of the current harmonics, the thermal load on the power components in the rectifier and in the DC-link capacitors is reduced as well as the harmonic effects on the supply. The use of a line reactor increases the service life of the converter.
Recommended line-side power components
Standard fuses can be used for the SINAMICS G120C. These must be dimensioned to comply with local regulations. In this chapter, you will find recommended components such as fuses and circuit breakers in compliance with IEC and UL regulations.
DC link components
Braking resistors
Excess energy in the DC link is dissipated in the braking resistor. The braking resistors are designed for use with the SINAMICS G120C. This has an integrated braking chopper (electronic switch).
Load-side power components
Output reactors
Output reactors reduce the rate of voltage rise (dv/dt) and the height of the current peaks, and enable longer motor cables to be connected.
Supplementary system components
Inligent Operator Panel IOP
Graphics-based, user-friendly and powerful operator panel for commissioning and diagnostics as well as local operator control and monitoring of SINAMICS G120C.
Basic Operator Panel BOP-2
A 2-line display to provide support when commissioning and troubleshooting the drive. The drive can be locally controlled.
Memory card
The parameter settings for an inverter can be stored on the SINAMICS SD memory card. When service is required, e.g. after the inverter has been replaced and the data have been downloaded from the memory card the drive system is immediay ready for use again. The associated memory card holder is integrated in the inverter.
PC inverter connection kit 2
For controlling and commissioning an inverter directly from a PC if the STARTER commissioning tool or SINAMICS Startdrive has been installed on the PC.
Spare parts
Shield plates
A set of shield plates is included in the scope of delivery for the motor and signal cables corresponding to the frame size of the SINAMICS G120C, and can also be ordered as spare parts.
Spare parts kit
This kit comprises four I/O terminals, one RS485 terminal, two pairs of Control Unit doors (1 × PN and 1 × other communication versions) and one blanking cover.
Set of connectors
A set of connectors for the line feeder cable, braking resistor and motor cable can be ordered corresponding to the frame size of the SINAMICS G120C inverter.
Roof-mounted fan
A roof-mounted fan (at the top of the device) comprising a pre-assembled unit with holder and fan can be ordered corresponding to the frame size of the SINAMICS G120C.
Fan unit
A replacement fan (at the rear of the device; heat sink) comprising a pre-assembled unit with holder and fan can be ordered corresponding to the frame size of the SINAMICS G120C.

软PLC控制技术是基于软件和硬件在逻辑功能上等效的思想，采用开放式体系结构，通过软件来实现PLC硬件的功能。软PLC系统由上位机和下位机组成，上位机为用户提供编辑界面和多种编程语言环境，便于用户在PC机上进行PLC程序的编辑，同时还对下位机的一些状态量进行监控，并给下位机发送指令。
用户编辑完PLC的梯形图和指令表程序后，只有通过对程序的编译来获取程序的逻辑后才能按照PLC的工作原理运行。为了配合在PC机上运行的软PLC编辑开发系统，使PC机完成相应的控制功能，开发了软PLC编译系统。
1、软PLC程序编译系统的组成
PLC编译模块由梯形图语法检查模块、梯形图程序逻辑检查模块和指令表程序语法检查模块组成。梯形图程序语法检查模块检查用户PLC图形程序有无指令标记重复、指令地址越界等语法错误;梯形图程序逻辑检查模块检查PLC图形程序有无逻辑错误;语言程序语法检查模块检查用户语句程序有无拼写、指令格式、指令地址越界等语法错误。
编译程序的构造包括词法分析、语法分析、语义分析、错误的检查和处理以及代码生成和代码优化等程序。
2、软PLC程序的遍历算法
软PLC程序的遍历算法主要包括梯形图遍历算法和指令表遍历算法。梯形图程序由若干个梯级组成，遍历时以梯级为单位，采用深度优先的扫描方法。按从上到下，从左到右的顺序进行。在扫描过程中，遇到并联结点就转入下一行进行扫描，行与行之间的切换由指针的变换来实现，原先位置的指针被预先存储起来，待并联模块扫描完后。再从原来的位置开始往下扫描。梯级和扫描顺序如图1所示。
图1 梯级和扫描图
指令表是由一系列指令组成。且指令按照链式结构存储，按照顺序读取指令即可完成对指令表的遍历。
3、梯形图与指令表程序的相互转换
3.1 梯形图转换成指令表
梯形图转换成指令表是以梯级为单位进行的。
对于没有并联支路的梯级，只要根据梯形图元素在梯级中的位置和元素的类型，即可将梯形图转换为指令表。对于包含有并联支路的梯级，可以按照遍历梯形图的方法，一边遍历一边转换。在转换过程中，首先设定1个全局变量nDepth(梯级深度)，以确定梯级的深度，然后判断1个梯级是否包含并联支路。如果包含则调用包含有并联支路的转换程序，然后顺序读入当前梯级深度层次上的梯形图元素;如没有发现并联支路，则调用不含并联支路的转换程序依次转换。在转换过程中。每转换完1条支路就要添加1个ORB支路并联指令。
在对整个梯形图程序进行转换时，首成nLine(行号)和nDepth 2个全局变量，然后从头开始进行转换，转换完1个梯级后。下1个梯级从第nLine(nLine=nLine+nDepth+1)行开始，直到梯形图文件结束为止。
3.2 指令表转换成梯形图
指令表转换成梯形图的过程就是根据PLC指令语句生成相应的梯形图元素链表的过程。因为梯形图和指令表程序是一一对应的关系，可按照语句对应生成相应的梯形图元素，利用在梯形图向语言表转换文件中已设计好的位图资源，建立标志符和位图之间的相应关系。转换时，将语句表以文件流的方式存入文本文件中，逐行分析，通过适当的算法处理，在视窗中画出对应的梯形图符号，直到文件结束。此外，在转换过程中，需要将程序划分为若干小节，每节对应梯形图中的1个梯级。在指令表中，梯级的划分可根据OUT指令来进行。串并联模块的划分可根据ANB和ORB指令进行。
4、软PLC程序的语法分析
在对PLC程序进行编译时，先将由PLC其他语言编写的程序转化为指令表后再进行处理。程序语言的文法通常包括I组终结符、I组非终结符、1个开始符号和1组产生式。
4.1 软PLC程序的文法设计
软PLC程序文法主要指PLC指令表语言的文法设计，PLC指令表语言与梯形图语言存在一一对应的关系。PLC的指令表程序由若干条语句组成，每条语句包括语句号、操作码和操作数。操作码是PLC指令系统中的指令代码，包括逻辑取、触点串联指令、触点并联指令指令、支路并联指令、支路串联指令和线圈驱动指令。操作数主要是PLC内部的继电器、定时器和计数器。下面是一段PLC指令表例程。
以三菱公司F1系列的逻辑指令为例来说明指令表文法的设计，并选取指令集中的一个子集来作为研究对象，该子集由逻辑取指令(LD，LDI)、触点串联指令(AND，ANI)、触点并联指令(OR，ORI)、支路并联连接指令(ORB)、支路串联连接指令(ANB)和线圈驱动指令(0UT)等基本指令组成。
为了便于分析，用单个小写字母代替指令，即LD，LDI→a;AND，ANI→b;OR，ORI→c;ANB→d;ORB→e;0UT→f。指令表的文法可表示为1个四元式(Vt，VN，S，φ)，其中，Vt是终结符号集，包括{a，b，e，d，e，f};VN是非终结符号集，包括{S，H，K，A，B，D，E};S是开始符号;φ中是产生式集(@代表空集)。因此，指令表程序的文法G[S]为S→aHfS; S→AfS;S→@;H→EH;H→@;K→EK;K→@，A→DA;A→@;B→e;D→b;D→c;E→D;E→aKB。
由G[S]产生式，可推出空串的非终结符集合为{S，H，K，A}。
4.2 软PLC程序的语法分析
语法分析选用自顶向下的LL(1)分析方法。为使用LL(1)分析方法，首先构造预测分析表，并先求取所有非终结符号的FIRST集和FELLOW集。
FIRST集：FIRST(S)={a，@，b，c};FIRST(H)={@，b，c，a};FIRST(K)={@，b，c，a};FIRST(A)={@，b，c};FIRST(B)={e，d};FIRST(D)={b，c};FIRST(E)={b，c，a}。
FOLLOW集：FOLLOW(S)={#};FOLLOW(H)= {f};FOLLOW(K)={e，d};FOLLOW(A)={f};
FOLLOW(B)={b，c，a，f，e，d};FOLLOW(D)={b，c，f，a，e，d};FOLLOW(E)={b，C，a，f，e，d}。
各产生式的SELECT集：SELECT(S→aHfS)={a};SELECT(S→AfS)={b，c，f};SELECT(S→@)={@，#};SELECT(H→EH)={b，c，a};SELECT(H→@)={@，f};SELECT(K→EK)={b，c，a};SELECT(K→@)={@，e，d};SELECT(A→DA)={b，c};SELECT(A→@)={@，f};SELECT(B→e)={e};SELECT(B→d)={d};SELECT(D→b)={b};SELECT(D→c)={c};SELECT(E→D)={b，c};SELECT(E→aKB)={a}
根据上述计算。生成的PLC文法预测分析表如表1所示。
表1 PLC文法预测分析表
通过表1，采用非递归的预测分析方法，构造预测分析器模型，如图2所示。
图2 非递归的预测分析器模型
预测分析器的控制程序总是根据栈顶符号和当前输入符号来决定预测分析器的动作，预测分析器的控制程序算法如下：
置指针ip指向输入符号串的第1个字符
while(1)
令X是栈顶符号。a是ip所指的符号;
if(X是终结符号或$)
if X==a
pop(X)，更新ip;
else
error();
else(X是非终结符号)
if M[X，a]：X—yly2?K
pop(X);
push(Y1Y2?K);
else
error();
else(X==$)
分析成功;
break;
其中，M[X，a]是指预测分析表中x行和a列相交处的产生式。
下面举例子来说明PLC程序语法分析程序的工作过程。
将指令用小写字母代替后，程序指令变为acababecdcf，将该字符串作为输入，分析过程如表2所示。
