2.3 Parameters
This section describes parameters.
2.3.1 Measuring Range Parameters
AI Channel Span
Specify the span using an integer.
Example If the range is -2.0000 V to 2.0000 V and you
want to set the span lower limit to 0.5000 V and the span
upper limit to 1.8000 V, set the parameters to 5000 and
18000, respectively.
SRangeAI,0001,VOLT,2V,FF,5000,18000,0
Scaling
Scaling is possible on AI and DI channels. Scaling is
specified by a mantissa and decimal place.
Example To set the scaling to -10.00 to 20.00, set the
scaling lower limit to -1000, scaling upper limit to 2000,
and the decimal place to 2. The decimal place value
represents the number of digits to the right of the decimal
point.
Math Channel and Communication Channel
Span
Set the span of math channels and communication
channels using a mantissa and decimal place.
Example To set the span to 1.000 to 2.000, set the
scaling lower limit to 1000, scaling upper limit to 2000, and
the decimal place to 3.
2.3.2 Parameter Notation and Range
The table below shows the principle parameter notations
and ranges of values.
Type Notation and Range of Values
AI channel
DI channel
DO channel
Specify as “unit number+module
number+channel.”
Example The AI channel whose unit
number is 0, module number is 1, and
channel number is 02 is 0102.
Math channel GX20/GP20: 001 to 100
GX10/GP10: 001 to 050
For SGroup and SMailAlarm
commands, insert “A” in front.
Example A001
Communication
channel
GX20/GP20: 001 to 300
GX10/GP10: 001 to 050
For SGroup and SMailAlarm
commands, insert “C” in front.
Example C001
Number of
channels for
recording

GX20/GP20: 001 to 500
GX10/GP10: 001 to 100
Number of
channels for
recording event
data
GX20/GP20: 001 to 500
GX10/GP10: 001 to 100
Type Notation and Range of Values
Number of

GX20/GP20: 1 to 60
GX10/GP10: 1 to 50
Number of
display groups
GX20/GP20: 1 to 50
GX10/GP10: 1 to 30
Number of
channels
that can be
registered to
display groups
GX20/GP20: 20
GX10/GP10: 10
Modbus
command
number
GX20/GP20: 1 to 100
GX10/GP10: 1 to 50
2.3.3 Specifying a Range
When specifying consecutive channel numbers or group
numbers in a setting command, you can specify them
using a range instead of specifying each number one by
one.
• Use a hyphen to separate the first number and the last
number. For I/O channels, you can specify a range that
spans over multiple slots that modules are installed in.
• You can specify the minimum number by omitting the
number before the hyphen and the maximum number
by omitting the number after the hyphen. If you want
to specify all numbers from the first number to the last
number, specify only the hyphen.
Example 1
To specify 3 to 10: “ 3-10”
To specify 3 to the maximum number: “ 3-”
To specify the first number to 10: “ -10”
To specify all numbers: “ -”
Example 2
A command that sets the channel ranges of AI modules
installed in slots 0 to 2 to Skip.
SRangeAI,0001-0210,Skip or
SRangeAI,-0210,Skip
If a different module is installed in slot 1, queries will work,
but setting commands will result in error.
