NJ-series CPU Unit Software User’s Manual (W501)
*1 Use the NanoSecToTime and TimeToNanoSec instructions to convert between durations and integer data. Refer to the
NJ-series Instructions Reference Manual (Cat. No. W502) for detailed instruction specifications.
*2 Variables are compared with nanosecond precision for comparison instructions. To change the precision for comparison,
use the TruncTime, TruncDt, or TruncTod instruction.
*3 A NULL character (1 byte) is added to the end of text strings. Therefore, reserve memory for one more character than the
number of handled characters. For example, if a maximum of 10 single-byte characters are handled, define a STRING
variable for 11 characters (11 bytes). STRING[11]
*4 If you want to insert tabs, line break codes, or other special characters, you can use a single-byte dollar sign ($) as an
escape character before them. Refer to Escape Character List on page 6-70 for a list of the escape characters.

beginning of the string and express the
date in the yyyy-mm-dd format.

Add “TIME_OF_DAY#”, “time_of_day#”,
“TOD#”, or “tod #” to the beginning of the
string and express the time of day in the
hh-mm-ss format.

Add “DT#” or “dt#” to the beginning of the
string and express the date and time in the
yyyy-mm-dd-hh:mm:ss format.
Example:

The default size is 256 bytes.
Enclose the string in single-byte single
quotation marks (‘).
