3.8 Output Commands
(Setting, Measured, and
Computed Data Output)
FC Outputs screen image data
Syntax FC p1
p1 GET (Output screen image data)
Example Output screen image data from the DX.
FCGET
Description The DX captures the currently displayed screen
and outputs the data in PNG format.
FE Outputs setup data
Syntax FE p1,p2,p3,p4
p1 Output data type
0 Setup data of setting mode
1 Decimal place and unit information
2 Setup data of basic setting mode
4 Setup data file
5 Setup channel information output
6 Configured alarm information
output
p2 First channel number (measurement,
computation, or external input channel)
p3 Last channel number (measurement,
computation, or external input channel)
p4 Format version (see “Setup Channel
Information Output” in “Response Format.”)
1
Format for Release number 2 or
Earlier (format version 1)
2 Format for Release number 3 or
later (format version 2)
Example Output the setup data of setting mode for
channels 001 to 005 from the DX.
FE0,001,005
Description • Make sure that the last channel number is
greater than or equal to the first channel
number.
• Parameters p2 and p3 are valid when p1 is
set to 0, 1, 2, 5, or 6. If you omit p2 or p3, all
channels are specified.
• Set parameters p2 and p3 by referring to the
table in section 3.3.
• Parameter p4 is valid when p1 is set to 5. If
you omit p4 when it is valid, p4 is set to 1.
FD Outputs the most recent
measured/computed data
Syntax FD p1,p2,p3
p1 Output data type
0 Most recent measured, computed,
and external input data in ASCII
format
1 Most recent measured, computed,
and external input data in binary
format
6 Relay status and internal switch
status
7 Event level switch status
p2 First channel number (measurement,
computation, or external input channel)
p3 Last channel number (measurement,
computation, or external input channel)
Example Output the most recent measured and computed
data for channels 001 to 005 from the DX in
ASCII format.
FD0,001,005
Description • The most recent measured and computed
data correspond to the most recent measured
and computed data in the internal memory
when the DX receives the FD command.
• Make sure that the last channel number is
greater than or equal to the first channel
number.
• Parameters p2 and p3 are valid when p1 is set
to 0 or 1. If you omit p2 or p3, all channels are
specified.
• Set parameters p2 and p3 by referring to the
table in section 3.3.
FF Outputs FIFO data
Syntax FF p1,p2,p3,p4
p1 Type of operation
GET Output starting with the next block
RESEND Retransmit the previous output
RESET Set the most recent data position
(block) to the FIFO buffer read
position (block)
p2 First channel number (measurement,
computation, or external input channel)
p3 Last channel number (measurement,
computation, or external input channel)
p4 Maximum number of blocks to read out
1200 DX1002/DX1004/DX2004/DX2008
240 DX1006/DX1012/DX2010/
DX2020/DX2030/DX2040/DX2048
60 Models with the /MC1 external
input channel option
If the amount of measured, computed, and
external input data is less than the specified
number of blocks, the DX sends all of the
available data.
Example Output two blocks of FIFO data from channels 1
to 10.
FFGET,001,010,2
Description • The FIFO buffer is a cyclic buffer in which the
oldest data is overwritten first. Use the FR
command to set the acquisition interval.
• The DX sends the specified number of blocks
(p4) of FIFO data starting with the next block.
