Configuration

Transformer terminal configuration

The Relay Configuration Tool is based on the IEC 61131-3 standard. The standard
defines the programming language used for the configuration. The programmable
system of RET 54_ transformer terminals allows the output contacts to be operated
in accordance with the state of the logic inputs and the outputs of the protection,
control, measurement and condition monitoring functions. The PLC functions (e.g.
interlocking and alarm logic) are programmed with Boolean functions, timers,
counters, comparators and flip-flops. The program is written in a function block
diagram language by using the configuration software.
After the configuration has been built and successfully compiled, and the MIMIC
configuration has been designed, the Relay Configuration Tool project (RCT project
in CAP 505) including the relay configuration and MIMIC configuration can be
downloaded to the relay with the Relay Download Tool. The project can also be
uploaded from the transformer terminal with the same tool. However, the relay
configuration, the RCT project and the MIMIC configuration are saved in a non-
volatile memory only after they have been stored via the parameter "Store". To
activate new configurations, the transformer terminal should be reset via the
parameter "Software reset". These parameters can be found in the menu
Configuration/General. Likewise, the storing and the resetting can be done
by using the relay command buttons "Store" and "Reset" in the Relay Download
Tool.
For more information about the configuration and the Relay Configuration Tool,
refer to the Configuration Guideline and the tool manuals (refer to "Related
documents" on page 9).
