Setting Commands

SScan
Scan Interval
Sets the scan interval.
Syntax
SScan,p1,p2
p1 Scan group (1 or 2)
When the measurement mode is Normal
or High speed, this is fixed to 1. When the
measurement mode is Dual interval, you can
select 1 or 2.
p2 Scan interval (see "Description")
Query
SScan[,p1]?
Example
Set the scan interval of scan group 1 to 1
second.
SScan,1,1s
Description
• You cannot use this command to configure settings
while recording is in progress.
• You cannot use this command to configure settings
while computation is in progress.
• The scan interval (p2) can be set in the following
range.
Measurement mode Options (p2)
Normal
(Notes *1, *2, *3)
High speed
Dual interval
(Notes *4, *5, *6, *7)
*1 If an electro-magnetic relay type analog input module
is installed, scan interval less than or equal to 500 ms
cannot be specified.
*2 If a low withstand voltage relay type analog input
module is installed, scan interval less than or equal to
200 ms cannot be specified.
*3 When the multi-batch function (/BT) is enabled, you
cannot set the scan interval to 200 ms or less.
*4 If high-speed AI type analog input module is installed,
scan interval less than or equal to 50 ms cannot be
specified.
*5 If an electro-magnetic relay type analog input module
is assigned to a scan group, scan interval less than or
equal to 500 ms cannot be specified.
*6 If a low withstand voltage relay type analog input
module is assigned to a scan group, scan interval less
than or equal to 200 ms cannot be specified.
*7 For dual interval measurement, scan interval cannot be
set less than 50 ms on scan group 2.
• The following three conditions must be met for an
option to be a valid scan interval.
1 When specifying a scan interval of 50 ms or
less, the modules installed in the main unit
must be assigned to scan groups.
2-14
100ms, 200ms, 500ms, 1s, 2s, 5s
1ms, 2ms, 5ms, 10ms
20ms, 50ms, 100ms, 200ms, 500ms,
1s, 2s, 5s
1ms, 2ms, 5ms, 10ms
20ms, 50ms, 100ms, 200ms, 500ms,
1s, 2s, 5s
2 When specifying a scan interval of 50 ms or
less, the number of channels must be within
the limits. (For the limits to the number of
channels for each scan interval, see the main
unit's User's Manual (IM 04L51B01-01EN, or IM
04L55B01-01EN).)
3 The shortest scan interval of the modules
assigned to a scan group is shorter than the
scan interval of the scan group.
The following table shows the shortest scan
interval of each module.

SScanGroup
Scan Group
Sets the scan group of the module.
Syntax
SScanGroup,p1,p2,p3
p1 Unit number
p2 Module number
p3 Scan group (1)
1 Scan group 1
Query
SScanGroup[,p1[,p2]]?
Example Set the module installed in the main unit,
whose module number is 2 in scan group 1.
SScanGroup,0,2,1
Description
• You cannot use this command to configure settings
while recording is in progress.
• You cannot use this command to configure settings
while computation is in progress.
• The scan group (p3) can be set in the following range.
Measurement mode
Normal, High speed
Dual interval
• The following three conditions must be met for an
option to be a valid scan group.
1 For a module installed in the main unit, assign the
module to a scan group with a scan interval of 50
ms or less.
