CIO Area, WR Area, HR Area, AR Area, DM Area, and EM Area banks 0 to C
(CJ2: 0 to 18)
Specifying I/O
memory areas
Specify the desired CPU Unit I/O memory area (data area) with a variable.
The data type can be specified with the variable.
The variables can be managed in groups.
data types
Maximum number
of variables
7,776 words total for all variables
Record Condition
Set whether or not to use a record condition.
If a record condition is used, sampling data is stored within the SPU Unit only when
the record condition is met. For example, sampling data can be recorded only while
a specified bit is ON or a specified word contains a particular value (comparison).
Data exchange
with the CPU Unit
CPU Bus Unit Area
CPU Unit to SPU Unit: Command execution (such as starting/stopping sampling,
clearing a sampling file, or saving a sampling file).
SPU Unit to CPU Unit: SPU Unit status information
Saving files Collected data file
CSV files Indices (record number), time stamps (hh:mm:ss:ms), ns, sampling
indices (serial numbers starting at 0 when sampling is started), data for
each symbol delimited with comma, records delimited with carriage returns
Number of
sampling result
records stored
in one file
Any one of the following methods can be used.
The number of records can be specified.
A time period can be specified. (The number of records is calculated automatically from
the time period and interval between samples.)
With a version 1.2 or later SPU Unit, the number of records can be left unspecified.
(In this case, data is added to the file until data collection is stopped. Records are
added to one file from the start of data collection until the end.)
Scaling Instead of directly storing the values collected from the CPU Unit's I/O memory, the
collected values can be scaled with a linear equation or upper/lower limit range before
storage (unit version 1.2 or later).
File size 2 GB per file
Record size Specified by user.
Number of records Specified by user or calculated automatically.
Saving method Data can be saved to a single file or multiple files (up to 1,200 files).
Network communications Windows network
shared folders
Files in the Memory Card inserted in the PC card slot in the SPU Unit can be shared
with a Windows XP, Vista, 7 or 8 personal computer.
FTP FTP server/client provided.
FINS server to execute FINS command
Routing to transfer FINS messages
Data Storage
(Unit Ver. 2.0
or later)
Number of fields 10,000
Recipe files File format: CSV
The file size is restricted by the size of file that can be stored in the recipe folder.
Records: Specified by the user.
Number of records No limit, but restricted by the file size that can be stored in the recipe folder.
Writing method Conversion method: Each field is written to the specified address in the specified data
Continuous region method: Data written to continuos memory addresses.
Searching for
recipe keys
Searching within files: The text string that was passed as the key is searched for in the
target search columns in the recipe files and the rows for any matches that are found
are extracted as recipe data.
Searching for file names: The text string that was passed as the key is searched for in
the recipe file names (i.e., a search is made for key.csv), and the files with matching files
names are used as recipe files just like previous versions.
Key list search: A search is made for recipe keys with the method used for unit version

*1. In both cases, the sampling cannot be performed faster than the CPU Unit's cycle time. The actual sampling interval
       will always be longer than the CPU Unit's cycle time even if the sampling interval is set shorter than the cycle time.
*2. The Data Collection Patterns use the data collected by the Basic Collection Pattern, so the data will be collected at the
       Basic Collection Pattern’s interval even if the Data Collection Pattern’s interval is set shorter than the Basic Collection
       Pattern’s interval.
*3. The actual Basic Collection Pattern interval will always be longer than the CPU Unit's cycle time even if the sampling
       interval is set shorter than the cycle time.
