A programmable logic controller (PLC) accessible to a database accesses a database (DB) server in response to an event in which a user program calls a DB access processing program. The DB access processing program stores status information indicating a status of accesses to the DB server in a nonvolatile memory, in accordance with an instruction of the user program. When a power interruption occurs, the PLC can obtain a status of accesses to the DB server at the timing of the occurrence of the power interruption by referring to the status information. Then, the PLC, for example, re-sends a structured query language (SQL) sentence, depending on the access status."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controller with enhanced reliability","description":"A controller with enhanced reliability of access to a database system.
