Now configure SM374 according to the module you need to simulate, that is; 48: Why does the voltage output of the S7-300 analog output group have tolerance? What are the terminals S+ and S- used for? It should be noted that in an S7-300 configuration, if you perform direct read access to the I/O across the module (using this command to read several bytes at a time), then incorrect values will be read. You can view the specific address in the hardware. Grounding sensor: Make sure that the sensor has a good equipotential connection. Installation clearance 2.2.2 Arrange modules on a single rack or multiple racks Whether to use one rack or multiple racks depends on the specific application.

Miniaturization

The module height of the S7-1500 is 155mm, and the modules are connected with U-shaped connectors. The reduced appearance and volume mean that it is easier to install and maintain, and the cabinet space occupied during system integration is smaller.

1.3.3 Easy operation of the display

The CPU has a built-in 6.1cm diagonal display, which can quickly access various text information and detailed diagnostic information, making it easy to fully understand all the information of the factory, thereby achieving full transparency of the entire factory. It supports hot-swappable operation of the display during operation, and the operation password of the display can be set using the TIA Portal.

1.3.4 Innovative module design

The standard unified 40-pin front connector saves users connection time and simplifies accessory storage.

The integrated shorting piece makes the voltage grouping simple and flexible.

The integrated guide rail enables quick and easy installation of other components such as circuit breakers and relays.

Due to the two pre-designed cable positioning grooves, the front cover can also be easily closed with large-diameter cables.

Due to the design of the pre-wiring position (steering wiring system with positioning device), initial wiring and reconnection can be simple and quick.

6SE7041-2WL84-1BH0 Almost all S5/S7 analog input devices still work in a complex way, that is, all channels are plugged into only one AD converter in turn. This principle also applies to the constant current required to read the impedance. Therefore, the current flowing through the resistor to be read is only used for short-term readings. For an SM331-7KF02-0AB0 with a selected interface suppression "50Hz" and 8 parameterized channels, this means that the current will flow approximately every 180ms, and each time there are 20ms to read the impedance. If the SM374 is used as a 16-channel output module, configure a 16-channel output module-use: SM322:6ES7322-1BH01-0AA0, use the programming cable to connect the programmer and the CPU. UISO: Potential difference between MANA and the M terminal of the CPU.

S7-1500 uses the current fastest backplane bus and efficient transmission protocol to ensure fast signal processing, and the point-to-point reaction time is less than 500us.

The resolution of AI and AO modules is 16 bits, the conversion time of each module of the 8-point AI module is 125us, and the digital input module has a short input delay of 50us.

The maximum signal frequency of the technology module TM Poslnput for counting, measuring and positioning input is 1MHz, and 4MHz at 4 times the speed. The pulse encoder can be connected via RS-422 interface, and equation mode, diagnostic interrupt and hardware interrupt are supported.

The use of PROFINET IRT communication can ensure a certain reaction time and high-precision system response, with a minimum cycle time of 250us.

1.2 CPU integrated technology function

1.2.1 Motion control function

The motion control function of S7-1500 is integrated in the CPU module, and no additional motion control module is required. Use TIAPortal to create projects and configure technology objects, and use the PLCopen standard control technology objects provided by TIA Portal. Motion control can use drives with PROFINET IO IRT and PROFIdrive interfaces, or drives with analog setpoints.

Motion control functions support speed control axes, positioning axes, and external encoder technology objects.

6SE7041-2WL84-1BH0 Please note that the long-term maximum value allowed for the input voltage is 12V, and the short-term (maximum 1 second) value is 30V. 59: What should be noted when using the encoder with FM357-2? If parameterized as "Word", two values can be read in. If a digital module is inserted in the 4th slot (for example: the module start address is 0), then the module will obtain the following address. 5. Analog input module: SM331; In order to realize the acquisition of 8-channel analog data, the input signal can be a current signal, a voltage signal, a thermocouple input, or a thermal resistor input. The module can be set according to different application scenarios. The following algorithm can be used: Address (index): b = element length * (index-1) When creating structures with different data types, it must be noted that padding bytes may be automatically inserted in certain environments.

6SE7041-2WL84-1BH0 This is because the DTR and RTS signals are set to 0 by default. You can call FC6 (V24_SET) in OB1. Set the parameters RTS and DTR to "TRUE". (1) 5V power consumption: The 5V power supply is supplied to the module by the CPU through the I/O bus cable. The 5V power supply cannot be supplemented or expanded by an external power supply. 2. CPU module: CPU314; it is the core of the system and is responsible for program operation, data storage and processing, communication with the host computer and data transmission.

Insulated gate bipolar transistor IGBT is a device composed of MOSFET and bipolar transistor. Its input is MOSFET and its output is PNP transistor. Therefore, it can be regarded as a Darlington transistor with MOS input. It combines the advantages of these two devices, with the advantages of simple and fast driving of MOSFET devices and the advantages of large capacity of bipolar devices. Therefore, it has been more and more widely used in modern power electronics technology.

In medium and large power switching power supply devices, IGBT has gradually replaced thyristor or GTO due to its simple control and driving circuit, high operating frequency and large capacity. However, in the switching power supply device, it is easy to be damaged because it works under high frequency, high voltage and high current conditions. In addition, the power supply is the front stage of the system. Due to the influence of power grid fluctuations, lightning strikes and other reasons, it is under greater stress. Therefore, the reliability of IGBT is directly related to the reliability of the power supply. Therefore, in addition to considering the derating when selecting IGBT, the protection design of IGBT is also a key consideration when designing the power supply.

IGBT:

1. It can be equivalent to (or understood as): a composite tube composed of field effect tube and high-power triode.

2. The characteristics are similar to field effect tubes. The input impedance is very high, the output impedance is low, and the driving power is very small. The driving current and amplification factor are mainly caused by the junction capacitance.

3. The switching frequency is high, the withstand voltage is high, and the current capacity is strong (the rated current is large).

4. Mainly used for: frequency converter (inverter), induction cooker, medium and high power inverter, argon arc welding machine, etc., high frequency power supply

The sampling end and the head end of the 6SE7041-2WL84-1BH0 potentiometer are connected to M+, the end is connected to M-, and S- and M- are connected together. 6. After commissioning, pay attention to observe the operation of the system. Each S7-200 digital module comes with a ribbon I/O bus cable. If the cable meets the installation width requirements between modules, the cable can be directly plugged into the 10-pin slot on other modules. 98: If you want to set the S5TIME type parameters in the PLC through the host or touch screen, what method is there? 1. Write an integer INT or real number REAL from the host computer to the PLC. First, the value must contain a time value in milliseconds. After writing it to the PLC's data storage area, use ITD (Integer to Double Integer) or RND (Real to Double Integer with Rounding Off) to convert the value to a double integer, then write the value to a variable of type TIME. Call FC40 in the program to convert TIME to S5TIME.
