Implementation Table The table below gives a list of all objects recognized and returned by the relay. Additional information is provided on the following pages including a list of the default variations returned for each object and lists of defined point numbers for each object.
Implementation Table Notes:
1.For this object, the quantity specified in the request must be exactly 1 as there is only one instance of this object defined in the relay.
2.All static data known to the relay is returned in response to a request for Class 0. This includes all objects of type 1 (Binary Input), type 10 (Binary Output), type 20 (Binary Counter), type 21 (Frozen Counter) and type 30 (Analog Input).
3.The point tables for Binary Input and Analog Input objects contain a field that defines to which event class the corresponding static data point has been assigned.
4.For this object, the qualifier code must specify an index of 7 only.
5.Delay Measurement (function code 23) is supported since the relay allows for writing the time via object 50 and it also periodically sets the “Time Synchroni- zation Required” Internal Indication (IIN). The IIN is set at
