LOGIC Data are stored each time the
specified event is generated.
p4 Data length
(10, 20, 40, 50, 100, 200, 300, 400, 500, 1k,
2k, 3k, 4k, 5k, 10k, 20k, 30k, 40k, 50k)
p5 Pretrigger
Example After generating a trigger signal, store only a file of
data length of 3K of the measured
data. Set the retention interval at 2 min, the
pretrigger to 10%.
MWTRIGER, TEST, 2 min, 3K, 10
Comments • This command is effective only with a floppy disk
drive function.
• If p1 is in DIRECT mode, the pretrigger setting
for p5 will be invalid.
• If p1 is in the TRIGGER or REPEAT mode, the
event/action functions need to set MEMRY:WR
_TRIG for its action.
• If LOGIC3 is set for p3, the event/action functions
need to set MEMRY:DATA_WR for their action.
• AUX, CON, PRN, NUL, or CLOCK cannot be
used in a file name. In addition, no space can be
used for the first character.
• When the pretrigger is set, the data ranges that
have been set before generating a trigger signal
are stored. Pretrigger setting is done in a
percentage of the data length. If 0 is set, the data
before generating a trigger signal cannot be stored.
MR Reads measured data that have been
stored on a RAM disk.
Mode Operation mode
Setting MRp1, p2, p3
p1 Read mode
DIRECT Reads measured data
immediately after sending a
MR command.
TRIGGER Reads measured data after
generating a trigger signal.
p2 File name (up to eight characters)
p3 Selection to begin reading data (YES/NO)
Example Read the measured data of a file name TEST
immediately after sending an MR
command.
MRDIRECT, TEST, YES
Comments • This command is effective only with an optional
floppy disk drive function.
• If the read mode is in TRIGGER, the setting of p3
will be invalid.
• If p1 is in the TRIGGER mode, the event/action
functions need to set MEMRY:RD_TRIG for their
action.
MV Stores setting data on a RAM disk.
Mode Operation mode
Setting MVp1
p1 File name (up to eight characters)
Example Store the setting data with the file name SET1.
MVSET1
Comments • This command is effective only with a floppy disk
drive function.
• Data set in the setup mode cannot be stored. To
store the data seting in the setup mode, use a YV
command.
ML Reads set data from the RAM disk.
Mode Operation mode
Setting MLp1, p2
p1 Method of reading the set data:
DIRECT Starts reading immediately
after sending an ML command.
TRIG1 to 3 Starts reading at the same time
as an event occurrence in
event/action functions.
p2 File name (up to eight characters)
Example Read the set data with the file name SET1
immediately.
MLDIRECT, SET1
Comments • This command is effective only with an optional
floppy disk drive function.
• Setting data in the setup mode cannot be read. To
read the setting data in setup mode, use YL
command.
• If any of TRIG1 to 3 is set to p1, the event/action
functions need to set MEMRY:LD_TRG1 to 3 for
their action.
• This command is not executable during
computation.
ME Deletes a file on a RAM disk.
Mode Operation mode
Setting MEp1, p2
p1 Type of file
DATAmeasured/computed data
PANEL
Setting data
p2 File name (up to eight characters)
Example Delete a file with measured data (TEST)
MEADATA, TEST
Comments • This command is effective only with an optional
floppy disk drive function.
• A setting data file in the setup mode cannot be
deleted. To delete it, use YE command.
MY Makes a copy of files between the
RAM and floppy disks.
Mode Operation mode
Setting MYp1, p2, p3, p4, p5, p6, p7, p8
p1 Copy destination/copy source
TO_FDD Copies a file from the RAM
disk to the floppy
disk.
FROM_FDD Copies a file from the floppy
disk to the RAM disk.
p2 Type of file
DATAMeasured/computed data
PANEL
Seting data
p3 File name (up to eight characters)
p4 ASCII conversion on/off
p5 First channel number for ASCII conversion
p6 Last channel number for ASCII conversion
p7 First data number for ASCII conversion
p8 Last data number for ASCII conversion
Example Make an ASCII conversion of data numbers 1 to 100
from the input channels 005 to
010 in the file TEST on the RAM disk and make a
copy of them on a floppy disk.
MYTO _FDD, DATA, TEST, ON, 005, 010, 1, 100
Comments • This command is effective only with an optional
floppy disk drive function.
• Parameters from p4 to p8 are effective only when
p2 is set to DATA.
• Parameters from p5 to p8 are effective only when
p4 is on.
