Analysis of PLC”s most basic serial communication
When using PLC, electric power operators will be exposed to many communication protocols and communication interfaces. Do you know the most basic PLC serial communication and basic communication interfaces?
Serial port is a very general device communication protocol on the computer (don”t confuse it with Universal Serial Bus or USB). Most computers contain two serial ports based on RS232. The serial port is also a common communication protocol for instruments and meters; Many GPIB compatible devices also have RS-232 ports. At the same time, the serial communication protocol can also be used to obtain data from remote acquisition equipment.
Serial communication is completed with three wires: (1) ground wire, (2) transmission, and (3) reception. Because serial communication is asynchronous, the port can send data on one line and receive data on another line. Other lines are used to shake hands, but are not necessary.
The most important parameters of serial communication are baud rate, data bit, stop bit and parity. For two ports to pass, these parameters must match:
a. Baud rate: This is a parameter to measure the communication speed. It represents the number of bits transmitted per second. For example, 300 baud means sending 300 bits per second. When we mention the clock cycle, we mean the baud rate. For example, if the protocol requires 4800 baud rate, the clock is 4800Hz. This means that the sampling rate of serial communication on the data line is 4800Hz. Generally, the baud rate of the telephone line is 1440028800 and 36600. The baud rate can be much larger than these values, but the baud rate is inversely proportional to the distance. The high baud rate is often used for communication between closely placed instruments.
b. Data bit: This is a parameter to Gas turbine system DS200TBQDG1A measure the actual data bit in communication. When the computer sends a packet, the actual data will not be 8 bits, and the standard values are 5, 7 and 8 bits. How to set depends on the information you want to send. For example, the standard ASCII code is 0~127 (7 bits). The extended ASCII code is 0 to 255 (8 bits). If the data uses simple text (standard ASCII code), then each packet uses 7-bit data. Each packet refers to a byte, including start/stop bit, data bit and parity bit. Since the actual data bit depends on the choice of communication protocol, the term “packet” refers to any communication situation.
c. Stop bit: used to represent the last bit of a single package. Typical values are 1, 1.5 and 2 bits. Because the data is timed on the transmission line, and each device has its own clock, it is likely that there is a small unsynchronization between the two devices in the communication. Therefore, the stop bit not only indicates the end of transmission, but also provides an opportunity for the computer to correct clock synchronization. The more bits applicable to the stop bit, the greater the tolerance of different clock synchronization, but the slower the data transmission rate.
d. Parity bit: a simple error detection method in serial communication. There are four error detection methods: even, odd, high and low. Of course, there is no check bit. In the case of even and odd parity, the serial port will set the parity bit (the bit after the data bit), and use a value to ensure that the transmitted data has even or odd logical high bits. For example, if the data is 011, for even parity, the check bit is 0, and the number of digits with high logic is even. If it is odd check, check bit 1, so there are three logical high bits. The high and low bits do not really check the data. Simply set the logic high or low to check. In this way, the receiving device can know the status of a bit and have the opportunity to judge whether there is noise interfering with communication or the data transmitted and received are not synchronized.
a. What is RS-232?
RS-232 (ANSI/EIA-232 standard) is the serial connection standard on IBM-PC and its compatible computers. It can be used for many purposes, such as connecting a mouse, printer or Modem, and also connecting industrial instruments and meters. For the improvement of drive and connection, the transmission length or speed of RS-232 often exceeds the standard value in practical applications.
RS-232 is only limited to point-to-point communication between PC serial port and equipment. The maximum distance of RS-232 serial communication is 50 feet.
b. What is RS-422?
RS-422 (EIARS-422-AS Standard) is the serial port connection standard of Apple”s Macintosh computer.
RS-422 uses differential signal and RS-232 uses signal of unbalanced reference ground. Differential transmission uses two lines to send and receive signals. Compared with RS-232, it can better resist noise and have a longer transmission distance. Better noise resistance and longer transmission distance are great advantages in industrial environment.
c. What is RS-485?
RS-485 (EIA-485 standard) is an improvement of RS-422 because it increases the number of devices from 10 to 32, and defines the electrical characteristics under the maximum number of devices to ensure sufficient signal voltage. With the ability of multiple devices, you can use a single RS-422 port to establish a device network. Excellent anti-noise and multi-device capability. RS-485 will be selected for serial connection when establishing distributed device network connected to PC, other data collection controllers, HMI or other operations in industrial applications.
RS-485 is a superset of RS-422, so all RS-422 devices can be controlled by RS-485. RS-485 can use more than 4000 feet of cable for serial communication.
