<a href="https://www.coolmayplc.com/plc-controller" rel="noopener noreferrer" target="_blank" style="color: rgb(230, 0, 18); user-select: auto;">PLC controller</a> touch screen control motor and reversing is an important link in PLC programming, so the difficulty is palpable. Some automation is a senior engineer in the early after 4 to 5 times of practice to master the skills. Today is for everyone to do a touch screen control motor and reversing practice. Need to prepare the material with a 24 v power supply of touch screen, and then the network interface, a used for touch screen and PLC and computer communication switch, a computer, a 24 v voltage module, a smart Siemens S7 - 200 of PLC plus two relay.the experiment began. First we have the electricity, the light has been on the <a href="https://www.coolmayplc.com/plc" rel="noopener noreferrer" target="_blank" style="color: blue; user-select: auto;">PLC</a>, then the touch screen is lit up. In order to ensure that the PLC and touch screen and computer communication, they must be set in the same network segment. Here is the IP address of the PLC is 192. 168. 0. 2, we need to set the IP address of the touch screen is changed to 0. 20.then we look at our computer IP is 0. 150, so they are in a network segment, thereby prove that can be connected to the normal. Before writing program should be a symbol table, with motor and reversing, it should be start stop, positive &negative switching, and output the forward and reverse output, we use where V0. 0， V0. 1。 2 do the startup command, stop command, and positive &negative switching, then Q0. 1,Q0。 1 is the motor do output forward and inversion of output, and then next we start programming.start programming. Make a start, where V0. 0,V1。 0, and then do a self-preservation, and then do the forward and inversion of command and positive &negative switching command. Down to be a coil, Q0. 0,。 1 then to download. After the monitor program is run smoothly, the watch you can see the program for the next step and monitoring.because our touch screen is the flexible V3, so we should use the touch screen software Wincc flexible smart, the screen is 700 IE V3. Point after opening, to connection, touch screen and <a href="https://www.coolmayplc.com/" rel="noopener noreferrer" target="_blank" style="color: blue; user-select: auto;">PLC controller</a> on this connection we are doing some variables based on the connection, because we use a switch, so the interface should be selected Ethernet. Since choosing Ethernet, you need to have the IP address, touch screen just transferred to 192. 168. 0. 20 and PLC is 192. 168. 0. 2, then according to the set to lose in these instructions, variable (like PLC do first Just did those where V0. 0,5. 1.5. 2 and Q0. 0, 1)。 as for the data types, we chose to Boolean. This cycle shorter, it scans the faster, the faster we can see that a reaction as a result, 100 milliseconds, shown here is not big enough, then turn off the left this, next we catch button, button below, there are three buttons here, is a start, one is to stop, a switch, and two status indicators, we copy this, then this button to change name, choose instruction into its chosen when press it.we choose instruction, should choose the into, make when press the setting is the effect of the button, or press the setting down, then lift the hand this is reset, so everybody see Resetbit and Setbit, so to form the effect of the button, but the language is the motor start and stop the push button, and then switch if it isn't, because the switch is made of the program, is press the switch, press the switch again to another, so the switch should be single cycle, you can see this for a while.the Siemens touch screen is more flexible, are interested can look at it. It has many tools, but also can realize many functions. We do next can only output state, we can make a green light. Double-click the selected circle, its properties option points out, change the border to the green, then fill color is green, then enable. The next Q0. 1 start, remember to change appearance attributes, and need to add a comment. Done, you have a look at the reaction on this side of the touch screen. Because we use two relay to represent the state of the motor, you can see, the touch screen can control the two relay, then the state implements the touch screen control motor. In the past few decades, <a href="https://www.coolmayplc.com/product" rel="noopener noreferrer" target="_blank" style="color: blue; user-select: auto;">programmable control systems</a> production has increased because of the use of plc manufacturers.The Global <a href="https://www.coolmayplc.com/about-us" rel="noopener noreferrer" target="_blank" style="color: blue; user-select: auto;">plc manufacturers</a> Leader.
