Share Siemens virtual PLC And configuration software iFIX Between TCP/IP Simulation Communication .

One 、TCPIP Protocol Brief

TCP/IP Transfer protocol , Transmission control / Network protocol , Also known as network communication protocol . It is the most basic communication protocol in network applications .TCP/IP The transmission protocol specifies the standards and methods of communication between various parts of the Internet . also ,TCP/IP Transmission protocol is to ensure the network data information in time 、 Two important protocols for complete transmission .TCP/IP Transport protocol is strictly a four layer architecture , application layer 、 Transport layer 、 Both the network layer and the data link layer contain . 

Two 、 Tools for protocol construction

• Win7 32 Bit virtual machine ：1 set

• Win  XP virtual machine ：1 set

• STEP7 And WinLC ：1 set     

• iFIX5.1：1 set

3、 ... and 、 Introduction to application software

01

STEP7 Introduce

STEP 7 Is a programming software , For Siemens series industrial control products, including SIMATIC S7、M7、C7 And based on PC Of WinAC Programming for 、 Monitoring and parameter setting , yes SIMATIC An important part of industrial software .STEP 7 Has the following functions ： Hardware configuration and parameter setting 、 Communication configuration 、 Programming 、 test 、 Start up and maintenance 、 Document filing 、 Operation and diagnosis functions, etc .

02

WinAC Introduce

SIMATIC WinAC It is developed by Siemens based on PC The core component of control , Its emergence extends SIMATIC S7 Control range of .WinAC It's a real control center , It will PLC control 、 Data processing 、 Communications 、 Visualization and process integration in one machine PC On board .WinLC yes WinAC One of the controllers in ,Windows Logic Controller,  It's executable S7 controller  (S7-300/400)  Functional soft PLC One of the systems   Application software executed on real-time operating system . It is based on real-time system , complete PLC Mission Software .

03

iFIX Introduce

iFIX yes Intellution Automation software product family （ Now it belongs to GE） One of them is based on Windows Of HMI/SCADA Components .iFIX It is a product based on open and component technology , Designed to provide an easy integration and collaborative work design environment between plant level and commercial systems . Its functional and structural features can reduce the time of developing automation projects , Shorten the time of system upgrade and maintenance , Seamless integration with third-party applications , Increase productivity .

iFIX Of SCADA This section provides monitoring management 、 Alarm and control functions . It can realize the absolute integration of data and realize the real distributed network structure .

iFIX Of HMI Part is the window to monitor and control the production process , It provides all the tools needed to develop a picture familiar to the operator .

Four 、 Protocol simulation environment building process

01

Environment configuration

Set two virtual machines and physical machines in the same network segment ：

• STEP7 IP：192.168.2.3

• iFIX5.1 IP：192.168.2.22

02

STEP7 To configure

• Site and hardware configuration

open STEP7, Insert a SIMATIC PC Site . Configuration configuration , Insert... Into the slot respectively WinLC RTX and IE General, And will IE Of IP Set to the IP192.168.2.3. Then save the compilation .

• Programming and downloading

newly build OB1 And DB block , And write a program , It is used as monitoring data when communicating with the host computer , More intuitive judgment of communication status .

03

iFIX To configure

• The system configuration

Open system configuration , Add and configure S7A drive . After configuring the device and block address , Monitor whether the communication status is good .

• Database manager

Open the database manager , Then add DI、AI Variables and PLC The variable addresses in the program correspond one by one .

• Add screen and run

New screen , Add pipe 、 Water pump 、 Labels such as outlet tank . Then associate the variables in the database . After the operation screen, press the start button of the water pump , The water pump start indicator changes to the running state （ green ）, At the same time, the liquid level will rise at a certain rate . When the liquid level is higher than the set value , High liquid level alarm will be generated , Prompt the operator that the liquid level is abnormal . Stop the water pump , The liquid level remains unchanged .

5、 ... and 、TCP/IP Application of protocol virtualization simulation technology

01

Virtual industrial scene simulation

Use this virtualization technology to build a virtualization platform , Can be infinitely close to the real control system 、 Monitor the virtualization simulation of the host computer , Realize the virtualization of typical industrial scenes , Such as petroleum and petrochemical 、 Thermal power 、 Water conservancy system 、 Intelligent manufacturing, etc .

02

Virtualized range management platform

Build the virtual industrial scene to the industrial Internet Security virtualization shooting range platform , For control 、 The monitoring system is virtualized and simulated , And can capture and analyze data traffic on it 、 Attack and defense drills to avoid damage to the real business network .
