4.8 Output Commands
(Setting/Measured/
Computed Data Output)
FC Transmits screen image data
Syntax FC p1<terminator>
p1 GET (Output the screen image data)
Example Output screen image data from the MV.
FCGET
Description Captures the current MV screen and transmits
the data in PNG format.
FE Transmits setup data
Syntax FE p1,p2,p3<terminator>
p1 Output data type
0 Setting commands setup data
1 Decimal place and unit information
2 Basic setting commands setup
data
4 Setup data file
5 Setup channel information output
6 Alarm information output
p2 First channel number (measurement/
computation/external input channel)
p3 Last channel number (measurement/
computation/external input channel)
Example Output the setting commands setup data of
channels 001 to 005 from the MV.
FE0,001,005
Description • Set the first channel number and last channel
number parameters so 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. All channels are specified if
parameters p2 and p3 are omitted.
• Set parameters p2 and p3 according to the
table in section 4.3.
FD Transmits most recent
measured/computed data
Syntax FD p1,p2,p3<terminator>
p1 Output data type
0 Output the most recent measured/
computed/external input data in
ASCII format
1 Output the most recent measured/
computed/external input data in
binary format
6 Output relay status and internal
switch status
p2 First channel number (measurement/
computation/external input channel)
p3 Last channel number (measurement/
computation/external input channel)
Example Output from the MV the most recent measured/
computed data of channels 001 to 005 in ASCII
format.
FD0,001,005
Description • The most recent measured/computed data
corresponds to the most recent measured/
computed data in the internal memory when
the MV receives the FD command.
• Set the first channel number and last channel
number parameters so 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. All channels are specified if
parameters p2 and p3 are omitted.
• Set parameters p2 and p3 according to the
table in section 4.3.
FF Transmits FIFO data
Syntax FF p1,p2,p3,p4<terminator>
p1 Operation type
GET Transmit the next block
RESEND Retransmit the previous output
RESET Set the most recent data position
(block) to the read position of the
FIFO buffer (block)
p2 First channel number (measurement/
computation/external input channel)
p3 Last channel number (measurement/
computation/external input channel)
p4 Maximum number of blocks that are to be
loaded
1200 MV1004/MV2008/MV1008
240 MV1006/MV1012/MV1024/
MV2010/MV2020/MV2030/
MV2040/MV2048
60 Models with the /MC1 external
input channel option
If the measured/computed/external input
data is less than the specified number of
blocks, the MV transmits the available data.
Example Transmit two blocks of FIFO data from channels
1 to 10.
FFGET,001,010,2
Description • The FIFO buffer is a cyclic buffer, which
overwrites the oldest data. Use the FR
command to set the acquisition period.
• The MV transmits the specified number of
blocks (p4), starting with the block after the
previously read block.
Make sure to read the data within the following
buffer period to prevent data dropouts.
• MV1004
FIFO buffer size: 240 cycles (scan interval)
Maximum buffer period: 240 × (acquisition
interval). Resending is not
possible after the buffer
period elapses.
• Parameters p2 and p4 are valid when p1 is
set to GET.
• If p4 is omitted, the MV transmits all blocks.
