Industrial-control equipment often requires programmable logic controllers (PLCs) and programmable automation controllers (PACs) to implement complicated control algorithms and loops. Translating raw ...

IL is gone, but Ladder remains—why does PLC Ladder logic survive even in the era of Structured Text?
"Ladder is outdated. The future of PLCs is Structured Text (ST)."In the world of FA, you sometimes see this kind of ...
Though PLC (programmable logic controller) programming languages may not receive the attention that general computing programming languages, such as JavaScript, C#, or Python do, they remain critical ...
「ラダーはもう古い。これからのPLCはStructured Text（ST）だ」 FAの世界では、ときどきこんな議論を見かける。 確かに、ソフトウェアエンジニアの目から見れば、ラダー図（LD）は古風に見える。 接点とコイルを横につなぎ、リレー回路のような図でプログラムを書く。一方のSTは、IF文、FOR文、配列などを扱え、一般的なプログラミング言語に近い。 複雑な計算やデータ処理なら、STのほうが ...
