• Writing the Measured Values of the Measurement Channels
• Writes the measured values of the measurement channels to the server registers.
• The data type of measured values is signed 16-bit integer.
• The values can be written directly including special data (See “Special Data Values”
in section 4.3). Perform data processing on the slave device.

• Writing the Computed Values of the Computation Channels
• Writes the computed values of the computation channels to the server registers.
• The computation function is an option (/M1, /PM1 option).
• The data type of computed values is signed 32-bit integer.

When the Data Type of the Write Destination Server Is Identical (INT32_B
or INT32_L)
The values can be written directly including special data (See “Special Data Values” in
section 4.3). Perform data processing on the slave device.
When the Data Type of the Write Destination Server Is Different (INT16
or UINT16)
INT16: A value in the range of –32768 to 32767 (excluding the decimal point) can be
written. If lower than –32768 the value reverts to –32768, and if higher than 32767 it
reverts to 32767.
UINT16: A value in the range of 0 to 65535 (excluding the decimal point) can be
written. If lower than 0 the value reverts to 0, and if higher than 65535 it reverts to
65535.
