Label data (1 point)
The following items are stored for each label.
• Data type ID: The data type of label name is stored with the defined ID. (Page 132 Data type ID)
• Read data length: Specify the read data size in byte units. (Page 133 Data length, unit specification)
• Read data: The value of read label is stored in the format of "Data type ID". (Page 135 Read data, write data)
• Spare data: The 2-byte of system data for data communication in ASCII code, and the 1-byte
communication in binary code is stored.
*1 For C24, the additional code may be added. (Page 35 Additional code (10H))
Communication example
Read data from three labels.
• Lbl1 (bit type) = 1 (ON)
• Lbl2.Lbl[2] (word type array element of structure label) = 0031H
• Lbl3 (word type) =0001H
The notation of each label when using abbreviation specification (Lbl2 = %1) is as follows.
