摘要： The present invention provides a technique for improving the reliability of access to a database system in a controller, such as a PLC (30, 40). A PLC (30, 40) accessible to a database accesses a DB server (20) in response to an event in which a user program (32) calls a DB access processing program (35). The DB access processing program (35) stores status information indicating a status of accesses to the DB server (20) in a nonvolatile memory (66), in accordance with an instruction of the user program (32). When a power interruption occurs, the PLC (30, 40) can obtain a status of accesses to the DB server (20) at the timing of the occurrence of the power interruption by referring to the status information. Then, the PLC (30, 40), for example, re-sends a SQL sentence, depending on the access status.
摘要翻译：本发明提供了一种用于提高对诸如PLC（30,40）的控制器中的数据库系统的访问的可靠性的技术。响应于用户程序（32）调用DB访问处理程序（35）的事件，数据库可访问的PLC（30,40）访问DB服务器（20）。数据库访问处理程序（35）根据用户程序（32）的指令，将表示对DB服务器（20）的访问状态的状态信息存储在非易失性存储器（66）中。当发生电源中断时，通过参照状态信息，PLC（30,40）可以在发生电源中断的定时获得对DB服务器（20）的访问状态。然后，PLC（30,40）例如根据访问状态重新发送SQL语句。

摘要： This invention provides a technique for facilitating debugging in a user program (186) which operates by cooperation of a PLC and another system in a control system (1) including a controller (104) and another system. A CPU unit (104) has a communication interface, executes a user program (186), calls DB connection service in accordance with an instruction included in the user program (186), and generates a statement to access a database device (400). In the DB connection service, operation is performed while switching a first mode and a second mode. In the first mode, a statement according to an access instruction is generated, the generated statement is transmitted to a database system (400), and a result of a response is sent to the user program (186). In the second mode, without transmitting the statement to the database device (400), a result of execution corresponding to the statement is sent to the user program (186).
摘要翻译：本发明提供了一种便于在包括控制器（104）和另一系统的控制系统（1）中通过PLC和另一系统的协作操作的用户程序（186）中的调试的技术。 CPU单元（104）具有通信接口，执行用户程序（186），根据用户程序（186）中包含的指令调用数据库连接服务，生成访问数据库设备（400）的语句。在DB连接服务中，在切换第一模式和第二模式的同时执行操作。在第一模式中，生成根据访问指令的语句，将生成的语句发送到数据库系统（400），将响应结果发送给用户程序（186）。在第二模式中，在不将该语句发送到数据库设备（400）的情况下，将与语句对应的执行结果发送给用户程序（186）。

The CPU unit (104) executes a user program (186) to call a DB connection service in accordance with an instruction included in the user program and generate a statement to access the database device (400). In the DB connection service, a statement according to an access instruction is generated, and the generated statement is transmitted to a database system. After that, information indicative of time until a response from the database system is received is acquired, and the acquired information is stored as a log into a memory. A support device (300) acquires the information and displays it on a monitor.
