The timer block has two ports and is considered an operation state block. The "True" port is output only when the timer has completed its time out, and ready to transfer to the next block (or state). The "False" port is output before time out. The false port must be looped back to the input of the timer block to remain within the timer state. If the state is changed (ie - if another state block is executed), the timer action will hault until that timer state is re-entered. For that reason, the false port should not be used to perform other actions or execute other blocks, while the timer is counting. The timer block should be considered as a "Pause" state utility.
If an application requires different actions based on time (for example, jogging at a given speed for five seconds before increasing to a faster speed), a manual timer can be created using the "mTime" system variable. Please read the attached document for further information on how to accomplish this.
