Mitsubishi PLC English name also known as: Mitsubishi Programmable Logic Controller, Mitsubishi Electric is the main product in Dalian. It uses a type of programmable memory for its internal stored procedures, performs user-oriented instructions such as logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of machinery through digital or analog input/output. Or production process. 1, flexible structure Without being restricted by the environment, it is possible to set up a network with electricity. At the same time, it is possible to flexibly expand the number of access ports so that resources can maintain a high utilization rate, which is comparable to wlan in terms of mobility. 2. High transmission quality, high speed, and stable bandwidth Watch DVD movies online in a smooth way. The 14mbps bandwidth it provides can be guaranteed for many application platforms. The latest powerline standard homeplug av has reached 200mbps; in order to ensure qos, homeplug av uses time division multiple access (tdma) and carrier sense multiple access (csma) protocols with collision detection capabilities. Stream media well. 3, a wide range The ubiquitous power line network is also an advantage of this technology. Although the wireless network can be achieved without breaking the wall, for high-rise buildings, it is necessary to deploy n multiple aps to meet the demand, and the same can not avoid the existence of blind areas of the signal. The power line is the most basic network. Its scale is unmatched by any other network. As a result, operators can easily penetrate this kind of network access service to wherever there is a power line. Once this technology has fully entered the commercialization stage, it will bring great development space for the popularization of the Internet. The end-user only needs to plug in a power cat to realize internet access, TV channels to receive programs, make phone calls or video calls. 4, low cost Make full use of the existing low-voltage distribution network infrastructure, without any wiring, saving resources. There is no need to dig trenches and make holes through the walls, which can avoid damage to buildings, utilities, and home furnishings, while also saving manpower. Compared with traditional networking technologies, plc has a lower cost, shorter duration, and greater scalability and manageability. At present, places where electricity broadband internet access has been opened in the country, the monthly subscription fee is generally around 50-80 yuan/month, and this price is flat with many places of the adsl monthly subscription. 5, wide application As an access technology using power line networking, plc provides broadband network "last mile" solutions that are widely used in residential areas, hotels, office areas, security monitoring and other fields. It is the use of power lines as communication carriers, making plc has great convenience, as long as in any room where there is a power outlet, without dialing, you can immediately enjoy 4.5 ~ 45mbps high-speed network Access, browse the web, make phone calls, and watch online movies to achieve "four-in-one" integration of data, voice, video, and power. 1. We use the X0 input as the timing start signal. When the PLC receives the timing signal internally, bit device X1 is turned on. Enter "ld x0" directly at the left bus bar to enter it in the ladder diagram. 2. We use T0 as the PLC internal timer. At this time, we should pay attention to the type of the timer: T0 ~ T199 represents the 100ms general-purpose timer, T200 ~ T2451 represents the 0ms general-purpose timer, which can be input "out t0 k30" at the back end of the input signal. K30 represents 3000 ms, ie 3 seconds. 3, when the end of the time required to have an output signal, this output signal can control the external device can also be used as a warning light, we use Y0 as an output. 4. If the timer is not reset after the timer expires, the timer will keep the last value. We can increase the reset command to reset C0. After completion, you can click the test button to simulate. 5. In the Logic Test Dialog Box, you can add bit device monitoring screens. Click “Device†in the menu and then select “Device Window†to select X and Y. At this time, you can operate and monitor the input and output of the programmed program. 6, in the X input dialog box, if you click on the input button can be self-locking input, click twice to unlock. When waiting for 3 seconds after clicking X0, Y0 will be output. At this time, if you click X1 twice, you can reset the timer and restart the timer after reset. Plc timing program, it is to use plc counter "c" to complete the timing. Plc timing procedure This program uses a special auxiliary relay M8013 (1s pulse input) as a second timer.
