Provide a variety of query, read and write interface.The application layer is mainly human-machine interface (HMI) and various visual function components, such as alarm interface, trend chart, report, chart, place order, change parameter, Chazhi and so on.more : is to adapt to a wide range, such as industrial gateway can support a variety of industry Ethernet, PLC, strong universality, can be applied to a number of

databases. It is equipped with a real-time database that can store various types of data, such as analog, discrete, and dense data, to exchange data with external devices. (5) programmable command language. A Programmable command language allows you to compile it based on your needs.ProgramTo enhance the graphic interface (6) Careful system security prevention. Different operators are assigned different operation permissions to ensure the safe and reliable operation of the entire system.

do you know which mode is the current one? You must obtain the list control and call clistctrl: getview: // in dialog classHWND hlc = ::FindWindowEx(m_hWnd, NULL, _T("SysListView32"), NULL);CListCtrl* plc = (CListCtrl*)CWnd::FromHandle(hlc);DWORD dwView = plc->GetView(); Clistctrl: getview returns one of the lv_xxx codes, but as Maarten finds, Windows returns lv_view_icon in both the icon and thumbnail mod

And so on, near spoon or swallowed, even hungry wolf-like flutter into the inside, slowly accumulation and understanding, a lot of knowledge points have perceptual understanding, more or less understand some, perhaps for memory, will these knowledge point collation collection, is to do a phase of the nature of the summaryAlso very welcome the exper

RTU is the abbreviation of remote TERMINAL UNIT, that is, remote Data terminal, used for monitoring, control and data acquisition applications. With telemetry, remote signaling, remote control functions. The RTU function must ensure two functions: 1, with data transmission function. 2, has the collection and the control function.After years of PLC+DTU in industrial automation applications have been widely used in this way in the online monitoring and

Strictly speaking, this article is not the OPC category. Cause is, another project of the PLC strongman said, OPC slow, with Prodave bar, good, use it, loaded well prodave look is to look at their English information, although English is not good, but fortunately English is very simple. Well, on the Internet to check some information, here also to thank a few friends to help, let me for C # and C + + data structure has a further understanding, but als

component with STEP7 the PLC function of the technical function template can be programmed for the vendor of the technical function software component without modification. Programmers use the STEP7 language (IL, LD, etc.) to write PLC programs, but the interface data blocks must be used to define the technical function interfaces of the software components. The software component is then generated in the

input registersThe Modbus protocol was first used to solve the communication protocol problem of PLC, mainly used for input and output digital signal and analog signal, so-called transmissionThe register is derived from the analog signal input, that is, the input register can only change the register from the analog signal input, and the host cannotBy issuing instructions to change the input register data, while the holding register is used to output

screen to Modbus device is as follows: first need to add a new device to the interface protocol of the program used by the Hmimaker touch screen, at this time the PLC type should choose "Modbus RTU Master", PLC interface can choose RS232 , rs4852w, RS485 4W or Ethernet, choose RS485 2 W here. As shown in 2. Figure 2 Setting the Hmimaker touch screen to a modbus deviceWhen the interface chooses to use RS4

conversion value is C0-Cm, real-time numerical value is Z. Therefore, B0 corresponds to A0, BM corresponds to AM, y corresponds to X, and y = f (x ). Because of the linear relationship, the equation is Y = (Bm-B0) * (X-A0)/(Am-A0) + B0. Because of the linear relationship, the mathematical equation z = f (x) After A/D conversion can be expressed as Z = (Cm-C0) * (X-A0)/(Am-A0) + C0. Then it is easy to obtain the inverse transformation of the mathematical equation x = (Am-A0) * (Z-C0)/(Cm-C0) +

I. project backgroundThe main purpose of the urban water supply network scheduling and monitoring system is to collect and monitor the data of water supply companies in various monitoring points. The system consists of a monitoring center and a water source monitoring point. The data collection terminal (RTU or PLC) of each water source monitoring point) it can monitor and collect various data such as water level, pressure, flow rate, turbidity, resid

Abstract: USB data acquisition controller is used in PC-based systems. Because of its ease of use and high price ratio, it has occupied a majority of the original data acquisition control card market, not only has it been widely used in OEM equipment, but also has replaced the traditional PLC system in many occasions and is applied to industrial control. This document uses labjack u12 as an example to describe how to use a USB data acquisition control

We have previously introduced the basic concepts of the CANopen bus protocol. Now we will take a look at the CANopen bus protocol equipment. First, let's take a look at the features of these devices through the following aspects. We will also know why CANopen bus is becoming increasingly popular in the market. Object Directory) The object dictionary is the central element of each CANopen bus protocol device. It describes all the functions of devices on the network. The object dictionary describe

master site, while 200 can only be used as the slave site.For example, the use of PROFIBUS-DP communications, 300, 400 settings for the main station, and 200 + em277 as the slave station for CPU communication. 1. When you use different communication protocols, the s7200plc can be used as the master station or slave station.For example, when the S7-200 CPU is reading and writing other S7-200 CPU data (using the PPI protocol) as the main site (the PPI main site can also accept data access from
