Configuration and Debugging Method of Modbus Communication Between Siemens S7-200 Smart and G120 Fre
1. System configuration1.1 softwareA PC with STEP7 micro / win smart software (including Modbus protocol library) installed. In this example, STEP7 micro win smart v2.0 is used.1.2 hardwareG120 is equipped with one frequency converter of cu240e-2 control unit, one asynchronous motor, one S7-200 smartplc, one standard drive-cliq cable and one twisted pair shielded cable. In this example, the firmware version v4.6 of the control unit cu240e-2 of G120 is used.Note: before using microwin software to create a project, confirm that the Modbus library file already exists.Figure 1-1 S7-200 smart interface2. Hardware wiring 2.1 cu240e-2 control unit interfaceThe terminal block of cu240e-2 control unit is shown in Figure 2-1. The RS485 interface is at the bottom of the control unit. There are five wiring terminals, from left to right. Terminal 2 is rs485p and terminal 3 is rs485n. These two terminals are used for transmitting and receiving communication data.Figure 2-1 terminal diagram of control unit2.2 G120 and S7-200 smart wiringFigure 2-2 wiring diagram of PLC and controllerS7-200 smart serves as the Modbus communication master station, and the wiring of its communication port and frequency converter slave station is shown in Figure 2-2. Terminal resistors need to be used at the head and end of the communication network. For S7-200 smart, a resistance of 120 ohms needs to be connected between communication port terminals 3 and 8. For the frequency converter, turn the cu240e-2 terminal resistance dial switch at the end of the communication network to the on position (the position is in Figure 2-1, label ⑨); For cu240e-2 in the middle position, the terminal resistance dial switch must be turned to the off position. In this example, S7-200 smart uses the CPU's own communication port to communicate with the frequency converter.3. Communication settings3.1 setting communication interfaceThis routine uses PLC Ethernet interface and drive-cliq cable to set communication interface, as shown in Figure 3-1 below.Step 1: double click communication to open the communication setting window;Step 2: select the network interface card and set it to "ICP / IP.

Performance Characteristics and Application Analysis of Boost DC / DC Converter Aat1230
Performance Characteristics and Application Analysis of Boost DC / DC Converter Aat1230
Aat1230:2mhz18v100ma boost converter returned by analogtech is used to supply power to organic LED, general LCD and CCD modules in portable system. Using all the architectures of advanced analogtech, the converter provides fast transient response, high stability, excellent load insulation, and reduces the system footprint.Portable system designers turn to OLED to take advantage of its thin waveform factor, lower power consumption demand and wider viewing angle. Designers need boost converter with fast transient response and zero leakage in non working state to ensure battery life. Leakage current loss can be minimized through hysteresis control and high stability. Aat1230 is an ideal dedicated power solution for OLED modules.Analogtech believes that stability is the core issue in the design of boost converter. In order to meet the needs of stability, aat1230 integrates a high-frequency converter up to 2MHz, has a feedback loop control mechanism, supports extremely fast CIS state response, and maintains stability in a wide range of load and input voltage without additional compensation elements. In addition, the high switching frequency of the device requires only minimal inductance and capacitance.Aat1230 adds a new feature to solve the inherent leakage current loss of traditional boost converter when driving OLED. In order to minimize current loss, designers using traditional boost converters usually use load switches and control circuits to disconnect the converter when the OLED module is disabled. Aat1230 adds a real load disconnection function. When en / set is pulled down, it can isolate the load from the power source, and its leakage current does not exceed 1? A。 This function simplifies the circuit design by removing the load switch and control circuit.In order to support most current OLED modules, the output voltage of aat1230 can be dynamically set by activating either of the two reference stages through the SEL logic pin. As the application of new generation OLED becomes more and more perfect, designers need more complex control mechanism. The dynamic output control function of aat1230 makes it easy for designers to realize conversion. By enabling the simple serial control (s2cwire) interface of setting pins and chips, designers can make the output brightness 16 different brightness levels.Aat1230 provides a series of safety features, including cycle to cycle current limit, short circuit and over temperature protection circuit at - 40 ° C to 85 ° C. The package form of the device is lead-free, 12 pin tsopjw package.
