Write a PLC ladder logic program that will provide a low voltage start to an electric motor.
Draw a ladder diagram in PLC programming for manually operated standing A+B+B-A- cylinder sequence.
A PLC is used to control a single-axis robot, in which the axis is driven by a pneumatic cylinder.
An output signal to the pneumatic cylinder causes it to extend (ON state). When there is no
signal, the pneumatic cylinder retracts (OFF state). The gripper is an also driven by a pneumatic
cylinder. The gripper open position is an OFF state and the closed position is an ON state. In
order to perform a task, the following sequence of operations must be performed:
TH
Sequence No.
Аxis
Gripper
OFF
OFF

ON

The process begins when the start bush button is ON and a part triggers a limit switch. For
safety, an emergency switch is used to shut off the entire system. Design a PLC ladder diagram
for this application.
