1. Support existing and future PLCs from various manufacturers
       We support over twenty different manufacturers of PLCs, including PS, Omron, Siemens, Mitsubishi, Modbus RTU, Modbus ASCII, LG, Delta, Telemecanique, Matsushita, and more. For the new PLC, we will also provide corresponding communication protocols on the network for you to update at any time (the product names and trademarks of each manufacturer mentioned in this article are owned by each manufacturer).
   

2. Convenient operation and communication macro instructions
      By utilizing computational macros to assist PLC in handling complex computational functions, and in conjunction with communication macro instructions, users can write their own communication protocols and connect to specific systems through COM ports
   

3. Quickly upload and download programs using USB
       Using USB Verl1.1/2.0 to download will greatly shorten the download time.
   

4. Can support two PLCs simultaneously
      Can support two communication ports at the same time, and can connect two controllers with different or the same communication protocol at the same time
   

5. Offline simulation function
       After editing, you can directly use a PC (without connecting the controller) to simulate whether the human-machine actions are correct
   

6. Online simulation function
      After editing, you can directly use a PC to connect the controller to simulate whether the human-machine operation is correct
   

7. Ethernet communication port
       The IO/100BASE-T Ethernet communication port provides fast data exchange function. Any TP can form a network for aggregation remote control, and engineering data can also be uploaded by Ethernet in a short period of time.
   

8. SD card backup data
      Use an SD card to backup data, or use the data inside the SD card to start another human-machine. After starting, burn the data into FLASH. This way, the same data does not need to be downloaded from a PC, and historical data and alarm messages can also be saved to the SD card. Users can use the card reader to read this data for sorting and printing.
   

9. Multiple confidentiality functions
       Provide password protection function to protect the intellectual property rights of program designers, and provide password function for the usage permissions of components in the screen. Only when the user's permission level is equal to or higher than this component, users can use this component.
