7.3 Output Format of BINARY Data
This section describes the output format of the BINARY data that is disclosed.
For information on other BINARY data, see “Identifier” on page 7-3.
• Measured/computed/control data and FIFO data.
• Display data
• Event data
The measured/computed data is output using signed 16-bit integer; the computed data is
output using signed 32-bit integer. Physical value is derived adding the decimal point
and unit. The decimal point position can be determined using the FE command.
Example of Deriving Physical Values from Binary Data
BINARY Data Decimal Point Position Physical Value (Measured Value)
10000 0 10000
10000 1 1000.0
10000 2 100.00
10000 3 10.000
10000 4 1.0000
Note
The “ CRLF ” used in this section denotes carriage return line feed.
Measured/Computed/Control Data and FIFO Data
• The FD command is used to output the measured/computed/control data.
• The FF command is used to output the FIFO data.
• The ID number of the output format is “1.” See “Identifier” on page 7-3.
