Connecting Signals In Smt - ABB Relion 650 Series Engineering Manual

Section 5
Protection and control engineering
All variables listed and shown in the parameter list can be sorted into two groups:
• Configuration parameter or
• Setting parameter
Configuration parameter
A configuration parameter specifies an operation mode of an application function or of the
IED. These are basic configurations, which are normally configured only once and then settled.
The IED configures itself at start-up according to the given configuration parameter values.
Setting parameter
A setting parameter (short form only "setting") is a parameter that can be changed in the IED
at runtime.
Setting group
Nearly all settings used by the IED for the protection application functions are organized in a
group of settings. Up to four setting groups can be configured with different values. The IED
supports the selection of a setting group at runtime.
IED parameters organization
The organization of the parameters in a tree structure is visible in the plant structure by
expanding the setting tree. For each function, the parameters are organized in basic and
advanced groups. The advanced settings are used for application optimization.

Connecting signals in SMT

SMT is used to do cross references, see
• between physical IO signals and function blocks.
• for the GOOSE engineering.
50
To export parameters from PST, both XRIO and CSV formats are supported.
Do not make PST read/write operation to IED when disturbance recorder is
storing data since that causes PCM600 to report that the IED is offline or
having communication problems.
During a common write both the basic and advanced settings are written to
the IED.
