Chapter One: General Informations
This communication protocol is based on the TCP IP protocol. For a better understanding of the following content, the reader is invited to learn about TCP IP from other documents.
TCP IP protocol is a data flow protocol. It is only responsible for sending and receiving data. It is not responsible for explaining the content and structure of data flow. The communication of this agreement is based on the frame implementation, so the following regulations are made on the format of the data stream:
Frames are the basic unit of communication. The unit of data sent and received in one communication is one frame.
The frame consists of a frame header, a frame body, and a CRC16 checksum. The frame header occupies two bytes, which indicates the length of the frame. The frame body is used to save the valid data that needs to be transmitted. The CRC16 check code occupies two bytes to ensure the integrity of the frame. The structure diagram is as follows:
Example: The frame length is FL, Then DL=FL-2-2.
The controller is implemented as a TCPIP server (communication parameters are set in the controller. Because TCPIP itself is a reliable communication protocol, CRC16 is not enabled by default). After the client establishes a connection with the controller, The frame can be constructed according to the above frame format and sent to the controller.
For example, send the hexadecimal data “00 01 02 03 04 05 06 07 08 09” to the controller, Then the frame “00 0c 04 05 06 07 08 09” is constructed. And send the controller, After the controller receives this frame, it will remove “00 0c”. Then get “00 01 02 03 04 05 06 07 08 09”.
What does “00 01 02 03 04 05 06 07 08 09” mean? The following begins to introduce the controller after receiving valid data, How to identify and process these valid data. The controller supports two types of frames: read register frame and write register frame.
Read Register Frame:
Write Register Frame:
This communication protocol supports reading and writing of the register data area. Communication implementation regulations: The register is a 16-bit data and the number of registers is 65536.

Note 1: In program test mode, The register (offset +3 to offset +19) is valid.
Note 2: In the constant test mode, The register (offset +3 to offset +11) is invalid. The valid registers are divided into the following two cases:
(a) Register (offset +14) takes a value of 0: the timer function is disabled, At this time, the register (offset +15 to offset +18) is invalid. Register (offset 19 valid).
(b) The register (offset +14) has a value of 1: Enable timing function. In this case, the register (offset +15-offset +19) is valid.

| ● | Note 1: The above is the register description assigned by the first program. The registers allocated by the 2nd to 120th programs can be deduced by analogy. |
| ● | Note 2: Mark the segment number as SEG. For SEGn (1<=SEGn<=120), Its register start address is: 66+(SEGn-1)*5. |
| ● | Note 3: Through calculations, we can see that, A program occupies a total of 666 registers. A total of 120 programs occupy 666*120=79920 registers. This has exceeded the size of the communication register area. |
| ● | Therefore, this communication protocol only supports reading and writing of databases from 1 to 96 programs. 96 programs occupy a total of 666*96=63936 registers. The range of registers used is: registers (offset +0-offset +63935). |
