Annex A (normative):
Summary of mandatory monitoring / supervision information
and functions
This annex gathers the information needed on the remote monitoring application for different types of power supplies. It
specifies the mandatory requirements that shall be provided in all cases.
NOTE: These tables do not specify the power equipment by itself. These tables refer to subsets or devices that are
not necessarily present in each equipment configuration. As a matter of fact, one alarm and its class apply
only in case of the presence of this subset or device.
When an optional alarm that requires a parameter set is present, the corresponding parameter set is mandatory in the
control section in order to allow remote adjustment under appropriate login procedure.
According to their types (Description, Alarm, Data, etc.), as defined in ES 202 336-1 [1] the information shall be
provided by the Control Unit (XCU).
NOTE: If there is no XCU this data can be provided by the Data Gathering Unit (DGU).
When a CU has a field data bus connected to the DGU, at least, the DGU shall store data (record measurements, log
files).The XCU which has the XML interface over Ethernet TCP/IP, shall store these data.

Annex A (normative):
Summary of mandatory monitoring / supervision information
and functions
This annex gathers the information needed on the remote monitoring application for different types of power systems. It
specifies the mandatory requirements that shall be provided in all cases.
NOTE 1: These tables do not specify the power equipment by itself. These tables refer to subsets or devices that are
not necessarily present in each equipment configuration. As a matter of fact, one alarm and its class apply
only in case of the presence of this subset or device.
When an optional alarm that requires a parameter set is present, the corresponding parameter set is mandatory in the
control section in order to allow remote adjustment under appropriate login procedure.
According to their types (Description, Alarm, Data, etc.), as defined in ES 202 336-1 [1] the information shall be
provided by the Control Unit (XCU).
NOTE 2: If there is no XCU this data can be provided by the Data Gathering Unit (DGU).
When a CU has a field data bus connected to the DGU, at least, the DGU shall store data (record measurements, log
files).The XCU which has the XML interface over Ethernet TCP/IP, shall store these data.
