Constant Duty Cycle
 Relay microblock

|
The Constant Duty Cycle microblock produces an output that cycles on and off according to the length of time you define for the cycle, and the percentage of that time you specify the output should be on.
The microblock only cycles the output when the go input is on; if the go input is off, the output remains on.

RefName
|
Use the default reference name unless you want a more descriptive name for this microblock for graphics, source tree rules, or network links. All reference names in a control program must be unique.
|
Output will be On (Duty cycle)
|
The Duty cycle __% ON time setting determines the percentage of the cycle that the output is on. For example, using the values shown in the microblock dialog below, the microblock's output would turn on for 7.5 minutes, then turn off for 7.5 minutes, then begin the cycle again as long as the microblock's go input stays on. The on time occurs at the beginning of the cycle, so if the duty cycle setting below were 20%, the output would turn on for 3 minutes, then off for 12 minutes.
|
Full cycle
|
In the Initial Values section, you can define the length of the complete cycle using the Full cycle every __ mm:ss setting.

Editing Privilege
|
Preset (the default Editing Privilege) indicates that each property in a microblock has an appropriate privilege assigned to it.
If you change the Editing Privilege, all the properties in that microblock are assigned to that one editing privilege, which is not always desirable.
