Ex.
Use 'specify from the device/label list' or 'specify the device range' in the following cases:
Case
Sampling a device not sampled by using 'device/
label batch specification'
Sampling a step in an SFC program not sampled by
using 'include SFC device' of 'device/label batch
specification'
Sampling values in the buffer memory not used in a program such as data for monitoring a module (using
for troubleshooting)
Sampling parameters not used in a program
Configuring multiple recording settings
Sampling data at a fixed cycle such as when using an interrupt program (when specifying "Trigger
Instruction")
When specifying devices and labels used in a project as sampling targets, the scan time can be shortened by
selecting 'specify from the device/label list' and specifying required devices and labels only.
For the operation to specify sampling targets from the device/label list, refer to the following:
Page 120 "Specify from the Device/Label List" screen
1 FUNCTIONS
38
1.1 Recording Function
Specifying index modification or indirect
specification in a program
Sampling data such as control data in an area
required for the operation of an instruction
Specifying a device for a numerical value (n) such as
the number of devices, transfers, units of data, or
character strings
Including multiple SFC programs
Specifying a step after the maximum step number in
each block in an SFC program in a program (adding
a block and step in the future)
Remarks

Disable 'device/label batch specification' and
specify only required devices as sampling
targets to reduce the size of data to be sampled.
