PLC Certification Exam Review
one uses relay control logic and the other uses programmed instructions - Answer-The basic difference
between a PLC and a relay control system is that:
Programming error, hardware configuration error, and error interrupted by a signal module - Answer-
What can cause the Error LED to light on the CPU?
Document a PLC program, write a control program, and monitor and control the process - Answer-PLC
software that runs on a personal computer can be used to:
%I 7.1 - Answer-The address of input IO of a 16-point digital input module whose start address is %I 6.0
would be?
M0.0 - Answer-Which of the following is considered a bit level address?
less secure from hacker attacks - Answer-Which of the following is not an advantage PLC's have over
personal computers?
Array - Answer-Which of the following is not one of the Atomic data types?
Sequential function chart - Answer-Which of the following PLC programming language consists of steps
separated by transitions?
WinCC Runtime advanced - Answer-Which application is run when the simulation of the HMI is started?
, inputs and outputs must be configured for the proper voltage and/or current levels. - Answer-Which of
the following is true regarding a new PLC?
Ethernet/IP - Answer-Which communication protocol is used on the advanced PLC Training System?
an output ON will tell you immediately whether the solenoid is functional when the program is
bypassed. If it is, the problem must be related to the software - Answer-Forcing
Up/down counter - Answer-Which of these is one of the counters in the Step 7 software?
check signals between output module and actuator - Answer-At the operator panel you found out that
the output of the PLC to execute the next step is set, but this step is not executed. Which action should
you take to find the fault?
Yes, with minor changes to the program - Answer-A normally open limit switch used in a machine has
failed and the only switch in stock is a normally closed limit switch. You do have access to the PLC
program. Can the switch be used?
Process Image of Outputs - Answer-PIQ
FFFF - Answer-Highest value possible in MW64 would be:
Power Source - Answer-What does AC/DC/Relay represent?
check the point where the output devices field wiring is connected to the output rack. - Answer-A single
output device has failed while the remainder of the PLC system is functioning normally. The indicator
light on the output module indicated that a signal is sent to the output point where the actuator is
connected, you would now -
