■Considerations for sampling labels
• Labels cannot be specified by using 'specify the device range.'
• By assigning a device to a global label, the assigned device can be set by using 'specify the device range.' (A device cannot
be assigned to a local label.)
• When sampling a label specified as an operand that uses a variable-length value, all members of a structure or all elements
of an array can be sampled by specifying a label defined as the structure or array as an operand. (Examples of
sampling targets for each instruction and operand)
■Considerations for specifying "Safety Cycle Time"
• When specifying "Safety Cycle Time" for the sampling method for a safety CPU, specify a time including the processing
time of the recording function for the safety cycle time in the CPU parameter.
Otherwise, a safety cycle processing error may occur due to delay in the processing time.
Set the time to sample required devices and labels only.
■Target data in a parameter
Devices and labels specified in the following parameters can be specified as sampling targets.
The host CPU module and modules under its control
*1 Excluding the following types of modules:
MELSEC-Q series module
Module not set in the I/O assignment setting in the system parameter
Module for which "Empty" is selected in the module status setting in the I/O assignment setting in the system parameter
Parameter type
CPU parameter
Module parameter
When also including parameters in the sampling target, devices and labels specified in the CPU parameter or
module parameter can also be included in the sampling target.
By including parameters to check the module status in the sampling target, the module status can be checked
by playing it when a trouble occurs.
However, the scan time becomes longer because the number of devices and labels to be sampled increases.
*2 A recording result for devices and labels used in a parameter can be checked in the watch window or device batch monitor by starting
offline monitoring.
