PLC可编程逻辑控制器
A Programmable Logic Controller is an industrial control device that receives input signals from sensors and switches, executes user-defined logic, and controls output devices to automate machinery and processes. In manufacturing localization, the term appears in electrical schematics, control descriptions, operator manuals, commissioning checklists, and troubleshooting guides where automation functions and safety interlocks are documented on the shop floor.

Where this term appears
PLC-related translation appears in ladder logic comments, I/O lists, alarm descriptions, and operator panel screens. Translators work on signal names, trigger conditions, timer and counter labels, and safety interlocks. Consistent terminology is critical because a poorly translated signal name can cause an electrician or maintenance technician to misread the control logic during startup or repair.
Translation checks
A typical mistake is translating PLC as a general-purpose computer or a relay, which hides its role in deterministic control. Another error is shortening or expanding signal names without following the project glossary, leading to mismatches between ladder logic comments, HMI labels, and electrical drawings. These mismatches can delay commissioning and make fault tracing harder.

Illustrative wording only. Confirm the rendering against the actual source and approved project terminology.
Check the distinction in context
A PLC address or tag is an identifier, while its description is translatable text. Preserve address syntax and distinguish physical input, logical state and screen label. Do not let a Chinese description imply a wiring change that the source does not instruct.
Check the returned Chinese file
Compare one Chinese tag description with the corresponding drawing and resource key. The description may change language, but the address, object relationship and source state should remain exactly identifiable to the engineering reviewer.
Prepare the connected files
Provide tag lists, relevant diagrams and the matching software revision. Confirm which fields are protected and who reviews electrical or control-system questions.
Keep the term aligned across your files
Check equipment names, units, safety instructions and interface labels against the source and approved references. Confirm any market-specific document requirements separately.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
