Overview:Preset
(mode, data, time.)
.
Network variables of SNVT_preset type are used to allow a sensor or actuator functional block to control and adopt one of several programmable values and ramp rates, in addition to the normal control mode. For a usage example, see the definition for the Closed Loop Sensor (SFPTclosedLoopSensor).
To program a preset, the SNVT_preset output is transmitted from a sensor with updated values for SNVT_preset.value, SNVT_preset.selector, and the time-related fields. In addition, SNVT_preset.learn is set to LN_LEARN_VALUE —or alternatively set to LN_LEARN_CURRENT, which causes the receiving actuator to learn whatever its current value is. A pre-programmed preset can be selected by transmitting the SNVT_preset output with the relevant preset number set in SNVT_preset.selector, and with SNVT_preset.learn set to LN_RECALL.
The time-related fields specify the time period over which the actuator should progress from the current level to the newly selected preset level. A benefit of this mechanism is that any set of actuators that are preset with a common rate value for a particular preset number, will all arrive at this new value at the same time, regardless of the individual preset values to which they ramp.
