Data Mapping
Data mapping for each model is shown in the table. The following symbols are used in
the table.
Symbol Explanation
CH, CH2 Data of the measurement channel or measurement channel 2.
CH0, CH2 Data of the computation channel 0 or computation channel 2.
C0, C24 Communication input data.
INT16 16-bit signed integer.
INT32_B 32-bit signed integer, BigEndian*.
* BigEndian: Assuming that a value of 01020304H is located as 01 02 03 04 in the buffer.
Note
• To acquire a physical value of the measurement channel data or computation channel data,
it is necessary to obtain the decimal place and unit information in advance.
• The channel data or communication input data that cannot be allocated in the I/O buffer is
not supported..
