1 Emeric MOTTE AEG Functional profile Wind Sensor Interface

2 1. Overview This functional profile implements a Wind Sensor Interface. This node works as an open loop sensor object. Its main function is to measure the wind speed from an anemometer, and transmit the measured value to controller objects. Additionally a threshold ( setpoint ) can be manually adjusted and then transmitted also to controller objects.

5 Network Variables Object Request network input SNVT_obj_request nvirequest ; This input network variable provides the mechanism to request a particular node for a particular object within a node. The meaning of the function codes for SNVT_obj_request are described in the SNVT Master List and Programmer's Guide ( ). The valid range is any value within the defined limits of SNVT_obj_request. The only mandatory request functions are RQ_NORMAL, RQ_UPDATE_STATUS and RQ_REPORT_MASK. Unsupported request functions must return invalid_request in the object status. It is not required to support object disable, self-test or alarm reporting. If object disable is not supported, the disabled bit in the status mask must be zero for that object. See below for a description of the status mask. If self-test is not supported, the fail_self_test and self_test_in_progress bits in the status mask must be zero for that object. If alarm reporting is not supported, the in_alarm bit in the status mask must be zero for that object. Supporting requests to object id 0 is optional. A request RQ_DISABLE to object id 0 means that all objects in the node should be disabled. If any of the objects in the node supports the disable function, then those objects should be disabled, and invalid_request should not be reported. However, if none of the objects in the node supports the disable function, then invalid_request should be reported. A request RQ_NORMAL to object id 0 means that all objects in the node should be enabled. This is always a valid request. A request RQ_UPDATE_STATUS to object id 0 updates the status of the node object only. The status bits of object id 0 (with the exception of invalid_request and invalid_id) are defined to be the inclusive OR of the status bits of all the other objects in the node, with the possible addition of error and other conditions attributed to the node as a whole, rather than to any individual object. For example, if comm_failure is supported for the node object, then it should be set whenever any of the objects in the node reports communications failure, as well as when there is a communications failure at the node level. A request RQ_REPORT_MASK to object id 0 causes the object to respond with a mask of supported status bits in the SNVT_obj_status output network variable. A one bit in the mask means that the node may set the corresponding bit in the object status when the condition defined for that bit occurs. A zero means that the bit may never be set by the node. 5/16

6 Object status network output SNVT_obj_status nvostatus; This output network variable reports the status for any object of the node. The valid range is any value within the defined limits of SNVT_ obj_status. The meaning of the fields of SNVT_obj_status are detailed in the SNVT MasterList and Programmer's Guide ( ). object_id invalid_id invalid_request disabled out_of_service mechanical_fault feedback_failure fail_self_test self_test_in_progress locked_out manual_control in_alarm in_override reserved1 reserved2 Used Used Used Used When Transmitted Data are transmitted whenever a value is received on the Object Request input and when the Object Status Max Send Timer expires. When the Object Status Max Send Timer expires the status of each object (including the node object) is returned sequentially in round-robin fashion, one object status per expiration of the timer. 6/16
