7. What does sourcing mean in PLC terminology?
Sourcing refers to the component that provides the current. In PLC terminology, if an output module is sourcing, it means the module provides the current to the load. If an input module is sourcing, it means the input device provides the current to the input module. Among the given options, option c describes a sourcing output module, where the module itself supplies the current.
- c. Output module supplies current to the output load
8. What does the term BOOL represent in PLC data types?
In PLC programming, BOOL is an abbreviation for Boolean. Boolean data types represent a binary state, typically true/false or 1/0.
- c. Boolean type data
9. What is the mode of operation called when a PLC continuously runs through its program and updates it based on input signals?
When a PLC is actively executing its program, reading inputs, and updating outputs in a continuous loop, it is operating in Run mode. The continuous loop itself is often referred to as the scan cycle, but "Run mode" is the overall operational state.
- b. Run mode
10. What is a Triac output module strictly used for?
A Triac (TRIode for Alternating Current) is a semiconductor device specifically designed for switching alternating current (AC) loads. Therefore, a Triac output module is used for AC operation.
- b. AC operation
