Application conditions are defined according to the installation location. Application may not be possible for some installation locations.
Page 21: Versions
Versions Versions Unit Versions Hardware revisions and unit versions are used to manage the hardware and software in NJ/NX-series Units and EtherCAT slaves. The hardware revision or unit version is updated each time there is a change in hardware or software specifications. Even when two Units or EtherCAT slaves have the same model number, they will have functional or performance differences if they have different hardware revisions or unit versions.

Page 59 3 Programming the DB Connection Function You need to set an appropriate value for the number of bytes used in the STRING data according to the data type and character code in the DB. In NJ/NX Series, text strings are handled as UTF-8. One byte is used for each single-byte alphanumeric character and multiple bytes are used for each multi-byte character.

3 Programming the DB Connection Function Precautions for Correct Use  When a data type that is not listed in the above tables is used in the NJ/NX-series Controller, the data may not be converted correctly.  When reading a value from a database using a DB Connection Instruction, an instruction error (SQL Execution Error) may occur because the data type cannot be converted due to the following reasons.
Page 65 3 Programming the DB Connection Function Pasting the Data from Microsoft Excel onto the Data Type Editor . Use two columns on Microsoft Excel to enter names and data types from the left. . In the 1st column, enter the data type name of the structure on the 1st line and each member name from the 2nd line.
Page 66 3 Programming the DB Connection Function Precautions for Correct Use You cannot paste the data type onto the Structure Data Type Editor in the following cases.  When a structure member is selected on the editor  When nothing is selected on the editor When executing the Paste operation on the Structure Data Type Editor, please select a structure data type, not a member.
Page 67: Creating A Db Map Variable
3 Programming the DB Connection Function 3-3 Creating a DB Map Variable After creating a user-defined structure data type for DB access, you create a variable using the data type. The variable is called “DB Map Variable”. This section describes the specifications and creation procedure of DB Map Variables. 3-3-1 DB Map Variables and DB Mapping Each DB Map Variable uses a structure data type for DB access as its data type.
Page 68: Registration And Attributes Of Db Map Variables
3 Programming the DB Connection Function Additional Information When a DB_CreateMapping (Create DB Map) instruction is executed to create a mapping for a DB Map Variable, it is not checked whether the structure members match the table’s columns. In this case, the DB_Insert (Insert DB Record), DB_Update (Update DB Record), or DB_Select (Retrieve DB Record) instruction will result in an error.
Page 69: Restrictions On Db Map Variables
3 Programming the DB Connection Function Precautions for Correct Use When a DB Connection Instruction is used in a function block and an in-out variable of the function block is specified as a DB Map Variable, system-defined initial values for the data types are applied to the members of the DB Map Variable when the DB Connection Instruction is executed.
Page 70: Specifying The Table And Applying The Mapping
3 Programming the DB Connection Function 3-4 Specifying the Table and Applying the Mapping You need to create a mapping from a DB Map Variable to the DB for each SQL type (INSERT, UPDATE, and SELECT) before you can execute a record processing instruction (for inserting, updating, or retrieving records).
Page 71: Restrictions On Db Mapping
3 Programming the DB Connection Function 3-4-3 Restrictions on DB Mapping The DB mapping has the following restrictions.  Restrictions on Table’s Column Names: When a character that cannot be specified for structure member names is used in a column name of the table, you cannot create the mapping.

Page 293: Impact Of Operation Log Recording On Execution Time Of Db Connection Instructions
Appendix B B-2-2 Impact of Operation Log Recording on Execution Time of DB Connection Instructions When the Operation Logs are recorded, execution time of DB Connection Instructions (i.e. DB_Insert, DB_Update, DB_Select, and DB_Delete instructions) gets longer. The following table gives the reference values for increased execution time of DB Connection Instructions while the Operation Logs are recorded.
Page 294: How To Measure Db Response Time
Appendix B B-2-3 How to Measure DB Response Time The DB response time refers to the time since an SQL statement is sent from the CPU Unit until the SQL execution result is returned from the DB. You can find the DB response time by executing a DB_GetConnectionStatus instruction after executing an instruction that sends an SQL statement.
Page 295: Instruction Execution Timeout
Appendix B B-2-4 Ensuring Equipment Performance (Takt Time) by Monitoring Instruction Execution Timeout If you do not want to lower the equipment performance (or extend the takt time) when the execution time of DB Connection Instruction is increased, set a timeout for the instructions. You can specify a timeout in the TimeOut input variable to the DB_Insert, DB_Update, DB_Select, and DB_Delete instructions.
