in the integer result. The FlexElement Base Units table in the Settings > FlexLogic > FlexElements section later, which
tabulates the per-unit base value used by its pickup setting and implies the per-unit base used by other FlexAnalogs, can
be of use in selecting a value for the RxGOOSE Analog1 PU setting.
Some UR elements have requirements for the type of input operands, for instance current type or voltage type. These
elements assume that RxGOOSE Analog operands are of whatever type is necessary to meet these requirements.
The per-unit base setting represents thousands, not single units. For example, a PU base of 1.000 is actually 1000 and a
PU base of 0.001 is 1.
When using RxGOOSE Analogs and PU base in FlexElements, the largest value that can be displayed in the FlexElement
actual values is 2,140,000.000.

An IEC 61850 Report server is an efficient method for delivery of generic substation event information in a single server to
a single client, such as a supervisory control IED. A Configurable Report is a UR element implementing an IEC 61850 Report
server, either of the buffered or unbuffered kind. The following table lists the number of Configurable Report elements.
Each Configurable Report element can report the values of up to 64 FlexLogic or FlexAnalog operands. Buffered report
elements queue value changes that occur while the client is offline and delivered when the client re-connects. Up to 512
events can be queued. Unbuffered control blocks purge all value change events when the connection to the client is lost;
any events that occur while the client is not connected are lost.

Unbuffered reports
Configurable Reports interoperate with any client device of any manufacturer that conforms to the IEC 61850 edition 1.0
or 2.0 report client requirements.
The entities whose values are reported by a Configurable Report are known as members. The members are itemized in an
ordered list known as a data set. Each Configurable Report can use any one of the data sets provided that no more than
four data sets are used for reports. This restriction is to limit the amount of processing power that can be allocated to
reporting.
Each enabled Configurable Report transmits an update to its client whenever a value change is detected in one or more of
its members. Also, the control block can be configured to send integrity reports containing the present value of all
members either on demand from the client or periodically. A TCP handshaking mechanism causes messages that are not
read and acknowledged by the client to be retransmitted.
