Details for DDEntity "205 - SC Turn On Time"

205 - SC Turn On Time Request changes
DefinitionThe Section Control Turn On Time defines the overall time lapse between the moment the TC sends a turn on section command to the working set and the moment this section is physically turned on and the product is applied. The working set may support this DDE as an optional feature to provide the possibility to store the time settings direct on the device to make the settings available after a power cycle. Therefore this DDE needs always to be setable by the TC and shall not be used to change any working set system behavior. The DDI shall support the On Change trigger so that the TC is able to get informed when the value gets changed by the Working Set Master. The TC shall active this trigger when using the DDI.
CommentThe SC Turn On Time setting is used to compensate the average physical machine reaction time (Electrical & Mechanical) from the moment the Task Controller send the command and the Working Set applies the product. To find the right time setting for the used system combination of Task Controller and Working Set it could take awhile and therefore it is a big benefit to store the setting on the working set to make them again available after a power cycle. For working sets supporting Section Control it is recommended to add SC Turn On Time to its device description and make it setable. In case where the device description contains also Physical Setpoint Time Latency or Physical Actual Time Latency the TC Turn On Time will always supercede it.
