Details
Sampling trace can be executed for each project.
Multi-project
Refer to (*6) for the timing of sampling when the multi-project is enabled.
The number between 1 and 8192 can be set. Note that, however, the total trace data size has to be smaller than
220 kilobytes.
Trace count
(The data size for a project depends on the number of usable projects.)
Refer to (*1) for trace data size calculation.
Trace count after trigger Sets the number smaller than the No. of traces.

Up to 50 points of word device, 50 points of bit device can be set. Note that, however, the total trace data size
has to be smaller than 220 kilobytes. Refer to (*1) for trace data size calculation.
Trace device
(The data size for a project depends on the number of usable projects.)
Applicable device: Refer to (*3).
(*1) Trace data size calculation
The trace data size in one project varies with the number of multi-projects that can be used.

User safety sequence
For example, if the number of usable projects is 6, set the number of traces and the trace devices so that the trace data
size is 25 kilobytes (25600 bytes) or smaller. Trace data size will be calculated as follows.
[Trace data size (byte)] = [Size required for one trace (byte)] x [Number of traces]
Size required for one trace is calculated from the number of word devices, the number of bit devices for trace and the size
required for one trace of each device. When time information is added, 4 bytes per trace is required.
Specifications
Trace on scan of main processes.
Word device Applicable device: Refer to (*2).
Setting condition: Set the value to be used for the condition and the
judgement. When the setting value becomes equal to the word device
value, or when the value of the word device changes judgement will be
effective and trigger is executed.
Bit device Applicable device: Refer to (*2).
Setting condition: Set ↑ or ↓ . When the setting condition is satisfied,
trace is executed.
Executes trigger by GX Works2 operations.
Word device Applicable device: Refer to (*2).
Setting condition: Sets the value to be used for judgement. When the
setting value becomes equal to the word device value, judgement will
be effective and trigger is executed. Refer to (*5) for when writing to the
device.
Bit device Applicable device: Refer to (*2).
Setting condition: Set ↑ or ↓ . When the setting condition is satisfied,
trace is executed.
