Note

• For INT32 or INT16, only the mantissa of the measured/computed data is acquired. The

decimal place must be obtained separately.

• For FLOAT, the measured/computed data including the decimal place can be acquired.
• The FLOAT and INT32 data domains are set so that they can only be accessed (read/write)

by the unit of two registers.

• Alarm statuses are output in the same format as those described in section 2.3, “Binary

Output.”
