What it does | This microblock limits the rate at which an analog signal may increase or decrease. When the microblock's go input is on, the microblock's ramp control is enabled. When the go input is off, the output value is equal to the input value. This microblock is often used as an additional safety measure to slow the reaction of a piece of equipment. This microblock can also be used in a sequence to prevent incoming requests from being canceled. For more information, refer to the appropriate request microblock description in SysIn Microblocks.
