Data Collection Using a PLC Unit

  • PLC data is collected in a PLC Unit with superior environmental resistance without using a computer.

  • Until now, data has been collected in PLC memory. Using an SYSMAC SPU Unit, however, eliminates the need for a PLC with a large-capacity memory and also eliminates the need for programming data collection in the ladder program.









Fast Collection of Large Amounts of Data with Data Concurrency

  • Using a computer for data collection presents the problems of a slow collection speed and low collection-point capacity. An SPU enables high-speed collection of large amounts of data.

Using a computer: Computer required for data collection. Communications via Ethernet or serial connection.

  • Direct use of the PLC bus instead of communications via a serial connection or LAN enables large amounts of data to be collected at a high speed.

  • Some data collection devices from other companies may not provide data concurrency. The SYSMAC SPU Unit, however, provides concurrency of simultaneous data.

Using an SPU: No computer required for data collection. High-speed, reliable data collection via the CS1 bus.




No Ladder Programming

  • No ladder programming is required for data collection. Data can be collected simply by performing the settings from the setting software (i.e., SPU-Console).

  • No need to leave extra space in the PLC memory for saving data.

Note: The PLC cycle time increases in proportion to the number of points collected.



Restriction-free Data Configuration Files without Depending on PLC Memory Space

  • Files can be created with the desired data configuration for only the necessary data from PLC memory.

  • The data to be collected can be stored in files in the required data type, such as BOOL, REAL, INT, BCD, or STRING.

  • Data configuration files required for the host computer can be created, so necessary data can be retrieved even if the SPU is mount in a device after the PLC is already set up.

  • CHANNEL_BLOCK has been added to the variable data types from SYSMAC SPU Unit version 2.0. When the data type is set to CHANNEL_BLOCK, the data in a consecutive memory area starting from the specified address for the specified number of elements is handled as a single data item with no commas.

Recipe Function NEW!

  • The recipe function enables writing numeric data (such as production parameters) and text strings to a memory area of the PLC. Using the recipe-writing function simplifies tasks such as retooling.
    (Note: The recipe function can be used only in Data Storage Mode.)
    * Numeric data and text strings to be written to a memory area of the PLC must be created in advance as recipe data (i.e., a CSV file) and stored in a Memory Card in the SYSMAC SPU Unit.

  • Ladder programming for developing recipe data is not required.

  • Using the recipe function saves PLC memory by saving recipe data to a Memory Card in the SYSMAC SPU Unit rather than requiring saving to the PLC data memory.

  • Recipe data can be written in response to a request from the PLC or from a computer or other external device.

  • Numeric data and text strings can be changed even when the SYSMAC SPU Unit is operating.

(1) The key is set from the ladder programming or from an external source and the Write Request Bit is turned ON. (2) The recipe data for the specified key is written to the PLC.



Data Connectivity with the Computer

  • The collected data can be loaded onto a computer via a PC card or Ethernet.

  • Data can be loaded onto the host computer with simple settings by using the Data Management Middleware software.

  • Using shared folders, data files collected in the SYSMAC SPU Unit can be accessed from a LAN-connected Windows computer just as if accessing files on the computer itself.

Collection Methods to Match the Application NEW!


Depending on the application, the Data Storage Mode can be used to collect data at a specific time or when there is a change in data, and the Sampling Mode can be used to accurately collect data at high speed. The Data Storage Mode enables establishing a system for error monitoring and production management for each lot or value by recording snapshots of data during production and when errors occur.


Note: The Sampling Mode and Data Storage Mode cannot be used at the same time.


Sampling Mode (Previous Function)
In this mode, I/O memory data for the PLC is sampled at a constant time interval. Data can be faithfully reproduced from the collected data.

Data Storage Mode
In this mode, the specified PLC I/O memory can be recorded when triggered by a specific event. The mode can be used to record data when a specified bit turns ON or at a specified time. Data can also continue being recorded at a constant time interval after an event occurs. This enables establishing a system for error monitoring and production management for each lot and value by recording snapshots of data during production or when errors occur.

Note: The time interval is less precise than the interval in Sampling Mode.



Event-triggered Collection Patterns


The patterns include memory events, which occur when a memory value matches a specified condition, and scheduled events, which occur at a specified time or time
interval. The occurrence of these events can be used to implement rules, such as those for starting and stopping data collection. (Applicable only in Data Storage Mode.)


Memory Events

  • Memory events can be set to generate an event when a change occurs in I/O data in PLC memory. Using memory events, events can be generated for a change in a bit ON/OFF status or by comparison to a set value (i.e., equal, above, below, or within range). For example, data could be collected only once when bit A turns ON. Alternatively, an event rule could be defined to start collection when bit A turns ON and stop collection when bit B turns ON.

Scheduled Events

  • Scheduled events can be set to generate an event at a specific date and time using Scheduler settings.

  • Event rules can be defined with Scheduler settings for collecting data as a result of events specified, for example, by the hour (e.g., every hour), day (e.g., every day), or week (e.g., every Monday). It is also possible to specify events by operating days or for the end of the month.


Collection Settings Changeable during PLC Operation

  • Collection settings can be changed and collection can be restarted without turning OFF the PLC.

  • Required data can be added and the collection interval can be changed even while the system is operating. Installing an SPU enables adding various systems after the system is already in operation.

Note: The PLC cycle time increases in proportion to the number of points collected.


Change collection settings, restart collection, add data and change the collection interval.


These functions enable the following applications simply by making settings.


The movement end position and filling pressure are recorded for each workpiece at events generated for starting and stopping filling.

Data is recorded when filling starts and stops.



Process data for each wafer can be recorded from receiving the wafer until completion.

Process data for each wafer can be recorded from receiving the wafer until completion.

During the testing, process data can be recorded for each product from the start of tests until completion.

During the testing, process data can be recorded for each product from the start of tests until completion.



Setting Software That Is Easier To Use than Ever Before

  • Project Explorer
    SYSMAC SPU Unit connection destinations can be managed using the SPU-Console. SYSMAC SPU Unit settings can be saved as projects, edited, and managed. For example, a project that has been previously set can be copied and easily reused.

  • Data Collection Status Display and Error Log Display
    The SYSMAC SPU Unit's operating status and error information can be displayed on the SPU-Console. A list can be displayed showing the status of data being collected, current errors, or error log. For example, the total time required to collect data and the total size of data collection files can be displayed.

  • Importing and Exporting Variable Definitions Using CSV Files
    All variable definitions can be exported to CSV files. Variable definitions can then be edited using software such as spreadsheets. Also, data on units and scaling, for example, can be batch-edited using a spreadsheet and imported to the SPU-Console.

  • Unit Setup Using the CX-programmer
    Unit setup for SYSMAC SPU Unit version 2.0 can be performed from CX-One version 2.1 (scheduled to be released this summer). IP addresses can be set from the CX-Programmer.
