SACA WRITTEN EXAM QUESTIONS AND
ANSWERS.
Can you define data analytics and its benefits? - CORRECT ANSWER Studying data to gain insights for
making decisions and taking actions.
Benefits include;
Providing better grasp of metrics which can lead to better operations
Predicting machine problems
Creating new ways to sell more services
Improving customer service
Can you describe types of automatic identification used in IloT? - CORRECT ANSWER Barcode
identification- using barcodes to identify parts as they go through a process
Radio frequency Identification- Uses wave lengths to exchange information between an RFID tag and a
reader.
Do you know the benefits of cloud computing? - CORRECT ANSWER Benefits include reduced cost,
speed, productivity, and reliability
Can you define Edge and Fog Computing? - CORRECT ANSWER Edge computing - Computing done near
the source of the data
Fog Computing - servers that provide connections between edge devices and the cloud. The fog layer
performs some data analysis and then sends the data to the cloud.
Can you describe how to power up a Rockwell CompactLogix PLC? - CORRECT ANSWER First turning on
the disconnect switch or main power switch. The LED will indicate once it's producing DC power. Then
the processor will self test before going into either program or run mode.
Do you know the basic components of Rockwell Studio 5000 software? - CORRECT ANSWER Controller
Organizer - presents the components of the project in a tree structure.
Ladder Editor- create and edit the PLC logic program
, I/O configuration folder - contains the hardware configuration of the project.
Ladder instruction toolbar- contains instructions that can be added to the ladder logic program.
Do you know how to configure an RSLinx EtherNet/lP Driver? - CORRECT ANSWER The configure drivers
window, opened by clicking the configure drivers tool.
Can you describe the operation of Rockwell Studio 5000 Timer/Counter instructions? - CORRECT
ANSWER .Pre - Preset value (What number you are counting down or up to.)
.ACC - Accumulated value (counting number value)
.DN - Done status bit
.TT - Timer timing status bit
.EN - Timer enabled status bit
Do you know how to create a Rockwell Studio 5000 PLC project? - CORRECT ANSWER Open the studio
5000 software, create a new project, assign the correct controller model number, name it, select
firmware revision, configure the expansion modules, configure the I/O modules.
Can you explain how to edit a Rockwell Studio 5000 PLC logic program? - CORRECT ANSWER The PLC
project and its ladder logic program must first be opened then it can be edited by adding and removing
instructions, changing logic or changing addresses.
Can you describe the operation of Rockwell Studio 5000 comparison instructions? - CORRECT ANSWER
EQU- Output turns on when value in source A is equal to value in source B
GRT - Output turns on when value in source A is greater than value in source B
GEQ - Output turns on when value in source A is greater than or equal to source B
LES - Output turns on when value in source A is less than source B
LEQ - Output turns on when value in source A is less than or equal to source B
NEQ - Output turns on when value in source A is not equal to source B
Can you describe the eight deadly wastes? - CORRECT ANSWER -Excess inventory waste is any finished
product, work-in-process, or raw material that is not needed for the next operation or the customer.
-Overproduction results in more product than the next process or customer needs.
