5.1.1.4. Condition monitoring functions
The condition monitoring function blocks are documented on the CD-ROM
“Technical Descriptions of Functions” (refer to “Related documents” on page 9).
5.1.1.5. Communication functions
The RET 54_ transformer terminal provides the IEC_103, Modbus
1
, DNP 3.0
1
, SPA
and LON serial communication protocols.
In a customer-specific transformer terminal configuration, special events can be
generated via an EVENT230 event function. EVENT230 is documented on the CD-
ROM “Technical descriptions of Functions” (refer to “Related documents” on
page 9).
For more information about communication in the RET 54_ transformer terminal,
refer to Section “Serial communication” on page 69.
