Click the blue text Follow us In practical control projects centered around PLCs, most of the time, we cannot do without the cooperation of touch screens or upper computers. This is because we use PLCs for control, mainly to process some analog quantities that we need to monitor, such as pressure, temperature, flow, and other … Read more
When learning English, we often strive to master standard pronunciation, but in reality, even native speakers may not always be very “standard”. Today’s lesson will teach you about words that Americans often “mispronounce”. Is it I can or I can’t? In English, some words have spellings that do not quite match their pronunciation: Spelling and … Read more
01 【SPI Concept】 SPI (Serial Peripheral Interface) is a synchronous serial port for communication between microcontroller units (MCUs) and peripheral ICs (such as sensors, ADCs, DACs, driver chips, and external storage devices). The communication rate can range from a few thousand bps to hundreds of Mbps or even higher, depending on the specifications and performance … Read more
Click the blue words Follow us 1. Introduction to CAN Background of the CAN Protocol In the 1980s, the number of electronic control units (ECUs) in automobiles gradually increased, and traditional point-to-point electrical communication methods were becoming inadequate. The point-to-point connections between each electronic control unit and other devices made system wiring complex, costly, and … Read more
Click the blue text Follow us Bit Time and Bit Synchronization in CAN Communication In CAN communication, Bit Time refers to the time required to transmit one bit on the bus, which is the reciprocal of the CAN bus communication rate (baud rate). CAN communication ensures reliable data transmission by sampling and synchronizing the signal … Read more
Serial communication methods such as ART, SPI, and I2C are very common in embedded development. The underlying principles of these communications are not difficult, but many beginners struggle to understand them. Today, I will share some common underlying data transmission principles of these communication methods. 1UART Serial Port UART: Universal Asynchronous Receiver/Transmitter. The UART serial … Read more
01 — Communication Connection Method 1.1 Connect the EPSON controller to the computer via USB cable 1.1.1 Open the EPSONRC+7.0 software, connect the controller using the USB cable, and stop the robot using the HMI. 1.1.2 Click ‘Settings’ – ‘Communication between Computer and Controller’. 1.1.3 Select ‘USB’ – ‘Connect’. 1.1.4 Choose the second option ‘Switch … Read more
1. The ABB robot controller has several network ports, defined as follows: 2. The several network ports within the Private Network essentially function as different ports of a switch. 3. By default, the Lan3 port is isolated, as shown in the image below. At this point, you can configure an IP for the LAN3 port … Read more
In the era of the Industrial Internet of Things (IIoT), when selecting controllers for industrial automation applications, it is essential to consider not only basic parameters but also data processing, communication, and high-speed control functionalities. Most industrial controllers, such as Programmable Logic Controllers (PLCs) and Programmable Automation Controllers (PACs), can handle basic functions like real-time … Read more
In industrial applications, there are many bus application scenarios, such as the conversion between RS-232 and RS-485 with bidirectional isolation, and the sharing of RS-485 and RS-422 interfaces. This article will introduce solutions for such applications that are not only simple and convenient but also improve communication reliability. High-Performance RS-232 to RS-485 Bidirectional Conversion Circuit … Read more
