How to Hire a SCADA / Control Systems Operator

Q: 02:40. The alarm summary is at about 400 alarms per hour. You have already shelved 38 points with no reason code. Two more “pump running” statuses are about to be shelved so the glass looks quiet. What do you do?

Correct answer: Stop the unruled shelves. Keep priority-1 (P1) and trip-class alarms live, call the field on the first-out process alarms, and log the flood rate and any approved shelf with owner, reason, and duration. Do not shelve 40 points just to clear the list. a is right: a 400/h flood is managed by keeping high-priority live, calling the field, and logging approved shelves — not by burying 40 points. b is the unruled 40-shelf the stem forbids. c hides the flood behind one key. d destroys the record instead of running the plant.

Q: What is the two-person rule on a critical Supervisory Control and Data Acquisition (SCADA) write?

Correct answer: A second competent person independently reads the tag, as-found value, and intended as-left before the write, then confirms the as-left after. It is for trip setpoints, forces, and other high-consequence points. It is not a second pair of eyes on a coffee mug. c is the rule: independent read of tag and values before and after a critical write. a shares a credential. b is a rubber-stamp after the fact. d treats a verbal as a verifier.

Q: A vendor sits at the engineering workstation and asks you to log them on with your write account “just to tweak a graphic.” Applying escort and write-account rules, what do you do?

Correct answer: Stay with them. Do not share your write password. If vendor work is approved, use a supervised vendor or engineering account, a change window, and a logged scope. Do not leave them alone on a write-enabled session. a is awareness: escort, no shared write password, approved account and window. It is not a method to get extra access. b abandons a write session. c publishes a credential. d puts a vendor on the live operator write keys.

Q: How do you prioritize competing tasks when multiple deadlines occur simultaneously in SCADA Operations?

Why it matters: Evaluates time management and prioritization under pressure. What to listen for: Green flags: Uses structured task lists, clarifies urgency with supervisors, and communicates transparently.

Q: Describe a time when you revamped an inefficient workflow in SCADA Operations. What was the measurable impact?

Why it matters: Evaluates continuous improvement and data-driven results. What to listen for: Green flags: Identifies root cause, involves stakeholders, implements measurable KPIs, and tracks ROI.

Q: How do you formulate a multi-year operational strategy in SCADA Operations that balances short-term profitability with long-term resilience?

Why it matters: Evaluates strategic foresight and executive acumen. What to listen for: Green flags: Aligns with market trends, incorporates scenario modeling, manages financial risk, and establishes clear milestones.

Q: On a Supervisory Control and Data Acquisition (SCADA) alarm summary, how does shelving differ from inhibit and from removing the alarm from service?

Correct answer: Shelving is a timed, owned hide of an alarm that still exists in the system and must come back. Inhibit or out-of-service is a longer engineering or maintenance suppression that needs a recorded reason and a restore. None of them is a substitute for fixing the process. b is the named distinction: shelf is temporary and owned; inhibit/out-of-service is a controlled suppression; neither replaces the process. a collapses three controls into one key. c invents a database delete. d treats a hide as a cleared plant.

Q: Production asks you to force PSHH-214 out of service so the compressor keeps running until 06:00. They will “put it back.” Applying independent-protection and management of change (MOC), what do you do?

Correct answer: Refuse. A trip is not a production convenience. If a temporary bypass is even allowed, it needs the safety-function owner, an MOC, a time limit, compensating measures, and a restore check — not a keep-running request. Do not disable the trip from the chair to make tonnes. d refuses a keep-running trip kill and points to owner, MOC, time limit, and restore — not a how-to bypass. a hides a force. b moves the trip instead of facing the request. c gags the field device, which this paper does not teach as a workaround.

Q: The night lead says do not write the 12-minute West remote terminal unit (RTU) loss in the shift book; “it came back, no one needs the noise.” What do you write?

Correct answer: Record start and end (12 minutes), last-value-held, which points were stale, who was called in the field, and that communications restored. Do not hide a comms loss because the graphic recovered. b is the shift-book rule: duration, held/stale, field call, restore. a writes a false quiet. c destroys historian evidence. d parks the truth off the record.

Q: Describe a situation where you had to handle an unhappy client or difficult colleague.

Why it matters: Evaluates emotional intelligence and professional de-escalation. What to listen for: Green flags: Listens actively, shows empathy, focuses on problem resolution, and follows SOPs.

02:40. The alarm summary is at about 400 alarms per hour. You have already shelved 38 points with no reason code. Two more “pump running” statuses are about to be shelved so the glass looks quiet. What do you do?

Easy

aStop the unruled shelves. Keep priority-1 (P1) and trip-class alarms live, call the field on the first-out process alarms, and log the flood rate and any approved shelf with owner, reason, and duration. Do not shelve 40 points just to clear the list.Correct
bShelve the remaining two and the next 20 so the rate falls under 50 per hour.
cHit Acknowledge All, then treat the board as healthy because nothing is flashing.
dTurn the alarm printer off so the 400 per hour is not on paper.

Explanation: a is right: a 400/h flood is managed by keeping high-priority live, calling the field, and logging approved shelves — not by burying 40 points. b is the unruled 40-shelf the stem forbids. c hides the flood behind one key. d destroys the record instead of running the plant.
