| Starting methods |
Basic
Collection
Pattern
(required) |
Any one of the following methods can be used:
Start when a specified event occurs. (Use a memory event or scheduled
event. For details, see the description of Data Collection Patterns 1 to
64 below.)
Start automatically when SPU Unit is started.
Start with an SPU-Console operation.
Start with the SPU Unit's front-panel command buttons. (Specify the
command number.)
Start from the CPU Unit's ladder program. |
Data
Collection
Patterns
1 to 64 |
Either of the following methods can be used to start when an event
occurs:
Memory events:
Start when a CPU Unit bit or word value matches a specified condition.
Up to 500 memory events can be specified.
Scheduled events:
Start at a specified time or time interval. Up to 16 scheduled events can
be specified. |
| Interval |
User-specified intervals: *2 *3
Basic Collection Pattern: 5 ms min.
Data Collection Patterns: 100 ms min. |

2.0 or later) |

Applicable CPU
Unit I/O memory
areas |
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. |
Variable
data types |
BOOL, INT, UINT, DINT, UDINT, REAL, LREAL, STRING, CHANNEL, UINT
BCD, UDINT BCD, WORD, DWORD, CHANNEL BLOCK |
Maximum number
of variables |
7,776 words total for all variables |
Record Condition
setting |
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
format |
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 |
Record
contents |
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
communications |
FINS server to execute FINS command
Routing to transfer FINS messages |
Recipe
function |
Data Storage
Mode
(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
type.
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
2.0. |
