8.3 Structure of Frame 

 

8.3.1 Structure of frame in the ASCII mode 

Frame structure in the ASCII mode is as follows.

(1) Characteristic of ASCII mode 

(a) In the ASCII mode, start of frame is indicated with colon (:), which is ASCII code, and end of frame is indicated 

with ‘CRLF’. 

(b) Each character allows maximum 1s interval. 
(c) How to check the error uses LRC, it takes 2’s complement except frame of start and end and converts it as 

ASCII conversion. 

 

(2) Address area 

(a) It consists of 2 byte.   
(b) When using the XGT Cnet I/F module, range of station is 0~31. 
(c) Station number 0 is used for client. 
(d) When server responds, it contains self address to response frame to know client’s response. 

 

(3) Data area 

(a) Transmits the data by using the ASCII data, data structure changes according to function code. 
(b) In case of receiving normal frame, it responds as normal response. 
(c) In case of receiving abnormal frame, it responds by using error code. 

 

(4) Error check area 

How to check error of frame takes 2

’

s complement except start and end of frame and converts it as ASCII. 

 

8.3.2 Frame structure in the RTU mode

(1) Characteristic of RTU mode 

(a) It uses hexadecimal. 
(b) Start character is station number and frame is classified by CRC error check.   
(c) Start and end of frame is classified by adding idle time of 1 bit. 
(d) Between frames, there is interval of 3.5 character time. When exceeding 1.5 character time, it is acknowledged 

as independent frame.   

 

(2) Address area 

(a) It consists of 1 byte.   
(b) When using the XGT Cnet I/F module, range of station is 0~31. 
(c) Station number 0 is used for client. 
(d) When server responds, it contains self address to response frame to know client’s response. 

 

(3) Data area 

(a) Transmits the data by using the Hex. data, data structure changes according to function code. 
(b) In case of receiving normal frame, it responds as normal response. 
(c) In case of receiving abnormal frame, it responds by using error code.
