Sample questions
01What is fieldbus communication?
- AAn analogue signalling method using 1-5V across a precision resistor
- BA digital communication protocol for networking field devices
- CA pneumatic signalling standard operating between 3 and 15 psi
- DA wireless link between a transmitter and a handheld configurator
Why: Fieldbus is a digital communication protocol specifically designed for connecting field instruments and control systems.
02What advantage does FOUNDATION Fieldbus offer over traditional 4-20mA?
- AIt can drive much longer cable runs without any signal repeaters
- BIt removes the need for any earthing or screening of cables
- CIt eliminates the need for a host control system or DCS
- DIt carries multiple variables and diagnostics over two wires
Why: FOUNDATION Fieldbus can carry multiple process variables, diagnostics, and configuration data over a single two-wire cable.
03What is a smart transmitter?
- AA transmitter with digital communication and self-diagnostics
- BA transmitter housed in an intrinsically safe enclosure
- CA transmitter that requires no external power supply to operate
- DA transmitter that outputs only a pneumatic 3-15 psi signal
Why: Smart transmitters feature digital communication, self-diagnostics, configuration capabilities, and often multiple sensor inputs.
Common questions
Is the Advanced Topics mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
