CG.4.2 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).
