Table notes:
1. The data link layer confirmation mode, confirmation timeout, and number of retries
are all configurable. Refer to the 745 instruction manual for further details.
The following table 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 input 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) and type 30
(analog input).
3. The point tables for binary input and analog input objects contain a field which
defines to which event class the corresponding static data has been assigned.
4. For this object, the qualifier code must specify an index of 7 only.
