SACA C-102 Certified
Industry 4.0 Associate -
Advanced Operations Exam
,Question 1
Responsibility for “Computerized Machine Operation” has been assigned to a practitioner.
Which activity fits that responsibility?
A. Machine safety guards, light curtains, emergency stops, and safety interlock verification.
B. Loading, verifying, and executing operational programs.
C. Processor, I/O modules (discrete/analog), power supply, and communication ports.
D. Updating process setpoints and operational variables securely.
Correct Answer: B
Full Explanation: Computerized Machine Operation includes Loading, verifying, and executing
operational programs. The important distinction is the activity being demonstrated, rather than the
fact that all four choices may describe useful work. A: This activity is directed toward Operational
Safety & Interlocks; it does not directly demonstrate the requested focus. C: This activity is directed
toward PLC Hardware Architecture & Operational Modes; it does not directly demonstrate the
requested focus. D: This activity is directed toward System Parameter Entry & Recipe Control; it
does not directly demonstrate the requested focus.
Question 2
An assessment of “PLC Program Troubleshooting & Modification” has so far covered “forced
I/O operations”. A colleague proposes replacing the remaining focus on “Online monitoring”
with “TON”. Which evaluation is most accurate?
A. The original two areas both belonged to Basic Ladder Logic (RLL) Programming.
B. The proposal simply repeats the same focus within PLC Program Troubleshooting & Modification.
C. The proposal shifts the remaining work from PLC Program Troubleshooting & Modification to
Basic Ladder Logic (RLL) Programming.
D. The replacement proves that the remaining original focus has been demonstrated.
Correct Answer: C
Full Explanation: PLC Program Troubleshooting & Modification includes Online monitoring, forced
I/O operations, and ladder logic modification. The proposed replacement concerns Basic Ladder
Logic (RLL) Programming. It therefore changes the scope of the work rather than demonstrating the
original remaining focus. A: The original areas belong within PLC Program Troubleshooting &
Modification. B: “TON” addresses Basic Ladder Logic (RLL) Programming, so it is not an equivalent
replacement. D: Substituting a different task does not supply evidence for the task removed from
the review.

,Question 3
An evaluation file groups two observations under “PLC Program Troubleshooting &
Modification”: “Online monitoring” and “Acknowledging, viewing, and clearing active alarms
and alarm history logs”. The second note is being reassigned by its content. Where does it fit
more directly?
A. System Diagnostics & Fault Finding.
B. Alarm Management & Trending.
C. PLC operational cycles.
D. PLC Program Troubleshooting & Modification.
Correct Answer: B
Full Explanation: The first note concerns PLC Program Troubleshooting & Modification. The
second, “Acknowledging, viewing, and clearing active alarms and alarm history logs”, concerns
Alarm Management & Trending. Separating the notes preserves their distinct technical purposes
rather than allowing the original filing location to determine their meaning. A: System diagnostics &
fault finding does not resolve the stated mismatch. C: Plc operational cycles is a separate focus and
does not describe the second note. D: This is the focus of “Online monitoring”, not the best match
for the second note.
Question 4
An assessment changes its emphasis from “Interpreting real-time data trends to monitor
system stability and process drift” to “mean time between failures (MTBF)”. Which
description best characterizes the change in focus?
A. It remains entirely within Alarm Management & Trending.
B. It remains entirely within Key Performance Indicators (KPIs) in Industry 4.0.
C. From Key Performance Indicators (KPIs) in Industry 4.0 to Alarm Management & Trending.
D. From Alarm Management & Trending to Key Performance Indicators (KPIs) in Industry 4.0.
Correct Answer: D
Full Explanation: The initial evidence, “Interpreting real-time data trends to monitor system
stability and process drift”, addresses Alarm Management & Trending. The later evidence, “mean
time between failures (MTBF)”, brings Key Performance Indicators (KPIs) in Industry 4.0 into the
review. Recognizing this transition prevents two distinct capabilities from being treated as
interchangeable. A: The later evidence introduces Key Performance Indicators (KPIs) in Industry 4.0.
B: The earlier evidence addresses Alarm Management & Trending. C: This reverses the direction of
the change.

, Question 5
Two possible extensions of a discussion about “Network Diagnostics & Connectivity Testing”
are “Verification of device communication using commands (e.g., PING)” and “Reading and
interpreting PLC project files and hardware configuration maps”. Which comparison best
explains their relevance?
A. The first introduces PLC Program Troubleshooting & Modification; the second extends Network
Diagnostics & Connectivity Testing.
B. The first extends Network Diagnostics & Connectivity Testing; the second introduces PLC
Program Troubleshooting & Modification.
C. Both additions are limited to PLC Program Troubleshooting & Modification.
D. Both additions are limited to Network Diagnostics & Connectivity Testing.
Correct Answer: B
Full Explanation: Network Diagnostics & Connectivity Testing includes Troubleshooting basic
connectivity issues between controllers, HMIs, and edge nodes. It also includes Verification of device
communication using commands (e.g., PING). By contrast, “Reading and interpreting PLC project
files and hardware configuration maps” concerns PLC Program Troubleshooting & Modification. The
distinction is whether the addition deepens the current focus or introduces another one. A: This
reverses the relationship between each addition and its competency. C: The first addition belongs
with Network Diagnostics & Connectivity Testing. D: The second addition concerns PLC Program
Troubleshooting & Modification.
Question 6
Two notes have been filed under “Sequential Process Control”: “Programming state-based
and step-sequential automated cycles” and “Adjusting process flow parameters to balance
production lines and maximize yield”. The second note is being reassigned by its content.
Where does it fit more directly?
A. PLC operational cycles.
B. Computerized Machine Operation.
C. Sequential Process Control.
D. System Optimization & Bottleneck Analysis.
Correct Answer: D
Full Explanation: The first note concerns Sequential Process Control. The second, “Adjusting
process flow parameters to balance production lines and maximize yield”, concerns System
Optimization & Bottleneck Analysis. Separating the notes preserves their distinct technical purposes
rather than allowing the original filing location to determine their meaning. A: Plc operational cycles
is a separate focus and does not describe the second note. B: Computerized machine operation
does not resolve the stated mismatch. C: This is the focus of “Programming state-based and
step-sequential automated cycles”, not the best match for the second note.
