NS Series Programming Manual
If no events have accumulated, event data will not be saved. ($SB33 will turn OFF and $SB47 will not
turn ON.)
If an error occurs during the save operation (e.g., the Memory Card is not in place, there is insufficient
free disk space, or the Memory Card is damaged), $SB33 will turn OFF and $SB47 will turn ON.
No error message will appear on the screen, however, when an error occurs.
If $SB32 and $SB33 turn ON simultaneously, initialization will be executed first. For this reason,
Alarm.CSV and Event.CSV files will not be created.
Internal Holding Memory ($HB/$HW) Initialization ($SB34)
$SB34 initializes the internal holding memories. When $SB34 is turned ON, the internal holding
memories ($HB0 to $HB8191 and $HW0 to $HW8191) are initialized. Once the initialization has been
completed, the system automatically turns OFF $SB34.
Initialize Data Log ($SB35)
$SB35 initializes the data log data. When “0” is stored in $SW37 and $SB35 is turned ON, data log in-
formation for all groups recorded by the PT is initialized. If a group number is stored in $SW37 and
$SB35 is turned ON, the data log information for that group only will be initialized. Once the initializa-
tion has been completed, the system automatically turns OFF $SB35.
Save Data Log ($SB36)
$SB36 saves data log data. When “0” is stored in $SW37 and $SB36 is turned ON, log data for all
groups is saved to the Memory Card as a CSV file. If a group number is stored in $SW37 and $SB36 is
turned ON, the data log information for that group only will be saved as a CSV file. Once the data has
been saved, the system automatically turns OFF $SB36.
When “0” is stored in $SW37 and $SB36 is turned ON, the data is saved to a series of files called
Trend001.CSV to Trend999.CSV in the Memory Card in the directory \log\ trend. If a group number is
stored in $SW37 and $SB36 is turned ON, the data is saved to a series of files called Trd00001.CSV to
Trd99999.CSV. The name of the folder will be the name of the output file. Trd00 to Trd99 can be
changed using the data log settings. Each time data is saved, a new file is automatically created, in-
crementing the file numbered each time. Up to 999 files can be saved. Only up to 099 CSV files will be
saved in each folder if the output file names are six characters or longer. When the number of files ex-
ceeds 999, existing files are overwritten in order beginning with Trend001.CSV or Trd##001CSV.
If there is no accumulated data log, the group number and data collection address will be output.
($SB36 will turn OFF and $SB47 will not turn ON.)
If an error occurs during the save operation (e.g., the Memory Card is not in place, there is insufficient
free disk space, or the Memory Card is damaged), $SB36 will turn OFF and $SB47 will turn ON.
No error message will appear on the screen, however, when an error occurs.
If $SB35 and $SB36 turn ON simultaneously, initialization will be executed first. For this reason, no
Trend#.CSV file will be created.
Initialize Operation Log ($SB37)
$SB37 initializes the operation log data. When $SB37 is turned ON, the operation log information re-
corded in the PT is initialized. Once the initialization has been completed, the system automatically
turns OFF $SB37.
