Notes:

The maximum number of TRACE instructions that can be programmed in a user program is three. Make sure that the folder name specified
by the TRACE instruction is not duplicated with the folder names specified by the other TRACE instructions. When the folders are duplicated,
trace data with a mixed format is output to the same CSV file.

The number of scans of which the trace data can be saved to the CSV file when the TRACE instruction is executed one time depends on the
number of devices specified to trace and the display type for each device. For details, see "9. Trace data size" on page 26-11.

The TRACE instruction cannot be used in an interrupt program.

Trace data is not accumulated when the TRACE instruction is skipped by the JMP (jump) instruction. For the JMP (jump) instruction, see
"Basic Instructions" on page 5-1 - "JMP (Jump) and JEND (Jump End)" on page 5-30.

While the input to the TRACE instruction is on, the trace data is repeatedly output to the CSV file. When you want to output the trace data
only one time, add a SOTU (single output up instruction) or SOTD (single output down instruction) to the input conditions. For SOTU (single
output up instruction) or SOTD (single output down instruction), see "Basic Instructions" - "SOTU and SOTD (Single Output Up and Down)"
on page 5-27.

The data writing process to the SD memory card for the TRACE instruction takes several scans. Once a TRACE instruction is executed, the
process continues until writing the trace data is complete, regardless of any change in the instruction input. While the trace data is being
written to the SD memory card, the instruction is not executed even when the input to the TRACE instructions are turned on. To execute the
TRACE instruction again, confirm that the previous data writing process has finished, and then execute the instruction.
Applicable CPU Modules
Valid Devices
Note: Specify the folder name by entering characters.
Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1.
Settings
1. S1 (source 1): Folder name
Specify the folder name on the SD memory card to store the trace data with a desired text up to 8 single-byte alphanumeric
characters.
Notes:

The following single-byte characters cannot be used in the folder names: 
/
\
: * ? " < > | # { } % & ~

Consecutive periods cannot be used in folder names.

A period cannot be used at the start or the end of the folder name.

Single-byte spaces at the start or the end of the folder name are omitted.
