What does inhibit and enable contacts mean?

More often than not, when normally closed control contacts under the operation of a coil are used in the ladder rung logic, their purpose is to prevent two operations from happening at the same time.Because of this, normally closed contact devices on ladder rungs are sometimes called inhibit contacts or devices, because the action of one operation inhibits some other operation from acting simultaneously.Likewise, more often than not, when normally open control contacts under the operation of a coil are used in the ladder rung logic, their purpose is to enable some other operation to happen at the same time.Because of this, normally open contact devices on ladder rungs and are sometimes called enable contacts, because the action of one operation enables some other operation to act simultaneously.
