PLC 1

QuestionAnswer
A PLC is a big computer False
Does a PLC have increased Reliability and accuracy? True
Plug-in compartments allow I/O modules to be easily connected and replaced True
The programming device must be connected to the controller to run the PLC False
A PLC is basically a mini computer designed for use in electrical control applications True
Initially the PLC was used to replace relay logic True
The number and type of I/Os cannot be changed in a fixed PLC True
The scan time is the time required for one complete execution of the user program True
The programming device must be connected to the controller to run the program False
A PLC is basically a computer designed for use in electrical control applications True
One disadvantage of modular I/O is its lack of flexibility True
Removing the programming device from the PLC will not affect the operation of the user program True
The instruction set for a particular PLC lists the types of instructions supported True
The number of I/O points does not affect the memory size required for a PLC installation False
Basically, the function of a PLC is to: make logical decisions and control outputs based on them
Which is not an advantage that PLCs offer over the conventional relay-type of control system> higher current capacity
The central processing unit: looks at the inputs, makes the decisions based on the program, and sets the outputs
The output interface module connects to load devices such as lamps or solenoids
The power required to operate the logic circuits of the processor unit is typically: low voltage dc
When a field device contact connected to the input module closes: a logic 1 is recorded in the memory location of the contact with the same address
Which module of the PLC connects directly to field devices such as pilot lights, motor starters and solenoids? output

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
