14. COMMUNICATION FUNCTION 
14 -  16 
 
14.4.2 Writing commands 
(1)  Status display (command [8] [1]) 
 
Command  Data No.  Description  Setting range  Frame length
[8] [1]  [0] [0]  Status display data deletion  1EA5  4 
 
(2)  Parameters (command [9] [4], [8] [5]) 
 
Command  Data No.  Description  Setting range  Frame length
[9] [4]  [0] [1] to [F] [F]  Writing each parameter 
Writes the values of the parameters in the parameter group specified 
with the command [8] [5] + data No. [0] [0]. Before writing the values, 
therefore, always specify the parameter group with the command [8] 
[5] + data No. [0] [0]. 
The decimal equivalent of the data No. value (hexadecimal) 
corresponds to the parameter No. 
Depending on the 
parameter
