First, sewage electromagnetic flowmeter communication method 1, after the connection line to the electromagnetic flowmeter power, enter the parameter setting screen, set the flowmeter communication address and communication speed.

2. On the CD, you can see two folders named "WIN98" and "WINXP". Select one of them according to your computer's system (WIN2000 also uses WinXP). There is a name in the folder. For the "SETUP" file, double-click to enter the installation state, and then follow the prompts.

3. After the installation is complete, you can see a new program named L-mag(51) is added in the start menu program. Click to open the communication test program.

4. Set the communication port on the software (some computers have two serial ports, only one serial port is set to com1), communication address and communication speed make him the same as you set in the electromagnetic flowmeter, click Start.

5. In this way, the corresponding data such as instantaneous flow rate and flow rate will be displayed on your PC. Click the multi-machine communication in the above communication menu to enter the multi-machine display.

6. The software automatically searches for the communication address. Click the menu above to display the data of multiple electromagnetic flowmeters. The data on the comparison computer should be the same as the data displayed by the electromagnetic flowmeter.

Second, sewage electromagnetic flowmeter communication protocol MAG5_MDBRTUV1.3 communication protocol uses the standard MODBUSRTU communication protocol. The MAG511 meter is a slave.

1. RTU mesغير مجاز مي باشدe frame definition The data communication is initiated by the host. The host first sends the RTU mesغير مجاز مي باشدe frame. The mesغير مجاز مي باشدe frame transmission starts with a pause interval of at least 3.5 characters. The first byte of the transfer is the device address. The transfer characters that can be used are hexadecimal 0...9, A...F. All slave devices constantly detect the network bus, including pauses. When the first address byte is received, each device decodes it to determine if it is destined for itself. A pause of at least 3.5 characters marks the end of the mesغير مجاز مي باشدe after the last transmitted character. A new mesغير مجاز مي باشدe can start after this pause.

The entire mesغير مجاز مي باشدe frame must be transmitted as a continuous stream. If there is a pause of more than 1.5 characters before the frame is completed, the receiving device will flush the incomplete mesغير مجاز مي باشدe and assume that the next byte is the address field of a new mesغير مجاز مي باشدe. Similarly, if a new mesغير مجاز مي باشدe starts with the previous mesغير مجاز مي باشدe in less than 3.5 character time, the receiving device will consider it to be a continuation of the previous mesغير مجاز مي باشدe. This will cause an error because the value in the last CRC field cannot be correct. The mesغير مجاز مي باشدe frame definition is as follows:

Wardrobe drawer

Laminate-smooth laminates are ideal for storing knitwear and shirts. The distance between the slabs should not be too large, otherwise the stacked clothes are too high, and it is easy to mess with the other when you take one of the clothes. Baskets are used to put T-shirts, which look clear and easy to find. Transparent drawers in front can also achieve this effect. Laminates and drawers are available in a completely pull-out style so that the deepest storage can be easily accessed. Individual laminates in the wardrobe can be designed to be active. When the number of garments increases or decreases, the position can be adjusted at any time.

Hanging wardrobe

The installation height of the clothes rail should be the height of the hostess plus 20 cm. When installing the clothes rail, it should be noted that the clothes rail must be taken within the actual depth of the wardrobe as a standard, and the distance from the top board must be 4-6 cm away, this size must be met, because the distance is too short Afterwards, it will be more difficult to put clothes on the shelves; the distance is too long and space is wasted. Note that the length of each cross should not exceed 120 cm, otherwise there will be problems with the load bearing of the pole.

Wardrobe storage box

The use of storage boxes to store items is easier to categorize, and the names of the items can be marked outside each box. The lidded box prevents dust from contaminating the clothes, and is easy to use even without cabinet doors. The box allows for better placement of irregularly shaped objects, such as some sports equipment. Hats and other incompressible items are also a good way to store them in boxes.
