PLC Programming Assessment

Use the software to create a LAD that illustrates the operation of RS latching relay in a described application and then simulate the program

Use the software to create a LAD that illustrates the operation counter for a given application.

Apply latching principle to start and stop a motor using simple logic blocks in FBD and LAD

Use latching principle to start and stop a motor using RS relay in FBD and LAD

Justify the safety reasons behind using NC push button to stop the motor instead of NO pushbutton with the aid of circuit diagram and LAD

Identify the relay contacts and coil terminals of the replay with the aid of circuit diagram

Identify the status of relays contacts (open / close) in a reversible motor control circuit with the aid of circuit diagram

Program the PLC to display a message on the PLC display unit using the ‘message text’ block. Use LAD/FBD to display the message.

Create a LAD and describe the circuit diagram for starting and stopping a motor in an unsafe stop method when using NO stop pushbutton.

Create a LAD and describe the circuit diagram for starting and stopping a motor in a safer stop method when using NC stop pushbutton.
