Run mode of the DB Connection Service Operation Mode or Test Mode
• Operation Mode: When each instruction is executed, the service
actually accesses the DB.
• Test Mode: When each instruction is executed, the service ends the
instruction normally without accessing the DB actually.
Spool function Used to store SQL statements when an error occurred and resend the
statements when the communications are recovered from the error.
Spool capacity 2 MB *9
Operation Log function The following three types of logs can be recorded.
• Execution Log: Log for tracing the executions of the DB Connection
Service.

Connection Service.
• SQL Execution Failure Log: Log for execution failures of SQL
statements in the DB.
DB Connection Service shutdown function Used to shut down the DB Connection Service after automatically
saving the Operation Log files into the SD Memory Card.
