Fixed to 1.
• When the BO flag is “0,” the MSB is output first. When the BO flag is “1,” the LSB is output first.
• If the check sum is enabled (parameter = 1) using the CS command parameter, each sum value is
inserted in the header sum and data sum sections in the “Conceptual Diagram” on the previous page. If
the check sum is disabled (parameter = 0), a zero is inserted in the header sum and data sum sections.
For a sample program that calculates the sum value, see “Calculating the Sum Value” on the next page.
• The bits that have “–” for the flag and flag are not used. The value is undefined.

• The table above shows the different types of BINARY Data.
• Measured/computed data can be output using the FD command.
• FIFO data can be output using the FF command.
• The setup data file can be output using the FE command. The setup data file can be loaded in the
cofiguration software.
• The identifier section in the “Conceptual diagram” on the previous page contains the ID number shown
above.
Note
BINARY data that are not indicated in the above table are considered undefined files.
• Calculating the Sum Value
If you set the parameter of the CS command to “1 (enabled),” the checksum value is output only during serial
communications. The check sum is the same as that used in the TCP/IP and is derived according to the
following algorithm.
Buffer on Which the Sum Value Is Calculated
• For the header sum, it is calculated from “data flag + identifier” (fixed to 6 bytes).
• For the data sum, it is calculated from “BINARY data.”
