Data Mapping
Data mapping for each model is shown in the table. The following symbols are used in
the table.
Symbol Explanation
CH1, CH2 Data of the measurement channel 1 or measurement channel 2.
CH101, CH112 Data of the computation channel 101 or computation channel 112.
C01, 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..
