communicate with other devices.
Drivers
PLC Project files contain which of the following?
ladder logic programs
hardware configuration
tags and communication configuration
PLCs store the information status of input and output modules by assigning each
terminal on the module a specific place in memory called a ___________.
Tag
The part of a PLC that executes the logic program is the ___________.
Proccesor
The power supply located in the chassis or backplane should only be used to
power the PLC modules.
True
The six basic components of most PLC's are the power supply, the input
modules, the output modules, chassis, processor, and the ______________.
Programming Device
, The two most popular communication protocols used with PLCs are Ethernet
and ________________.
Universal serial bus (USB)
Typically, a USB driver will not automatically start when the programming device
detects the connection and needs to be configured using specific software.
False
USB, or _________________ commuication requires a cable connection from the
programming device to the PLC controller module.
Serial
Which is proper sequence of operation within a PLC?
Examine inputs, perform logic, update outputs
Which of the following statements describes PLC Program mode?
Allows the user to download, upload, edit and save project files. The processor
does not scan or execute the ladder program, and outputs are not energized.
Which of the following statements describes PLC Run mode?
Allows the user to upload, save, edit, and monitor the operation of the PLC
project. The processor executes the ladder program, monitors status of inputs,
and energizes appropriate outputs.
Based on the diagram below, which statement accurately describes when Y
output will be energized?
X1 = true, X2 = false, X3 = true
In the I/O diagram below, what information does the absolute I/O address for
any of the inputs or outputs tell you?
