Object Description
This object implements energy control functionality, i.e. energy specific settings, in the host application. The implementation of this object is optional. All instance attributes shall be seen as required and must be implemented in the application. If the Anybus module detects that an attribute is missing during run time an appropriate network error is sent and the Discard Responses counter is increased in the Anybus Object instance attribute Error Counter.
Each enabled instance in the object corresponds to an Energy saving mode. The number of available modes is device specific, and must be defined by the application. The higher the instance number, the more energy is saved. The instance with the highest number always corresponds to the “Power off” mode, i.e. the state where the device is essentially shut down. Instance 1 of the object represents “Ready to operate”, i.e. the mode where the device is fully functional and does not save energy at all. Consequently a meaningful implementation always contains at least two instances, one for energy saving and one for operating. If this object is implemented for PROFINET, at least three instances are needed: “Ready to operate”, “Energy saving mode 1”, and “Power off”.
Highest number of instances is 8. Please note that these modes are always present – they are not dynamically created or deleted. It is not allowed to leave holes in the list of instances.
