4.4 Setting Commands (Setting)
IM MV1000-17E
intervals after the power is turned ON and
transmits the data when a FF command is
received. The previous output position is
held for each connection. Upon receiving
an FF command, the MV transmits the next
data and updates the output position. This
scheme compensates for the differences in
the processing power of the measurement PC
and the communication delay. This enables
data to be retrieved without dropouts if the
measurement PC reads the data before the
ring buffer is overwritten. For the output flow
diagram of FIFO data, see appendix 5.
BH Sets a batch text field
Syntax BH p1,p2,p3,p4
p1 1
p2 Field number (1 to 8)
p3 Field title (up to 20 characters)
p4 Field characters (up to 30 characters)Field
title (up to 30 characters)
Query BH[ p1,[ p2]]?
Example Set the title to “OPERATOR” and the text to
“DAQSTATION” for field number 2.
BH1,2,OPERATOR,DAQSTATION
Description For the characters that can be used, see
appendix 1.
EH Sets a calibration correction
If p2 is set to BEGIN
Syntax EH p1,p2,p3
p1 Measurement channel number
p2 Type of operation (BEGIN)
p3 Number of break points in the calibration
segment (OFF, 2 to 16)
OFF
Calibration OFF
2 to 16 Number of break points
If p2 is set to SET
Syntax EH p1,p2,p3,p4,p5
p1 Measurement channel number
p2 Type of operation (SET)
p3 Break point designation (1 to 16)
p4 True value of the specified break point

• The selectable range of p4 and p5 varies
depending on the current set range.
• If set to scale range, the selectable range of
p4 and p5 is –30000 to 30000.
• Set true value p4 so that the value increases
as break point p3 increases.
If p2 is set to END
Syntax EH p1,p2
p1 Measurement channel number
p2 Type of operation (END)
Example Example in which three break points are
specified on CH2
EH002,BEGIN,3
EH002,SET,1,0,1
EH002,SET,2,50,49
EH002,SET,3,100,101
EH002,END
Description • First, execute this command with the type of
operation set to BEGIN to specify the number
of break points.
• Set the values for the specified number of the
break points using the SET operation.
• Execute this command with the type of
operation set to END to finalize the settings.
• The EH2? command transmits the CH2
settings.
• The output example is as shown in the
example above.
• You cannot execute this command while the
MV is computing.
BD Sets an alarm delay
Syntax BD p1,p2
p1 Measurement, computation, or external
