Local control

Local control refers to control operation from the front panel of the IED. Either the DIR or the
SBO modes are available depending on the configuration selected by the user.
Remote control
3.5.2
Remote control refers to control operation from a remote control center or the SAS server.
Either the DIR or the SBO modes are available depending on the configuration selected by the
user. Note that the parameters used in the control commands are defined in international
standards†. The parameter details are provided in the communication profiles. (See Chapter
Communication protocol and Appendices
†Note: As a rule, the control commands have parameters. For example, the "Off to On"
and "On to Off" control directions that are used in commands are pre-configured
as parameters in the communication protocol. Note that the parameters vary
depending upon the respective protocol used, such as IEC61850 and others. For
IEC61850, Table 3.5-2 shows the parameters defined: the rule for control direction
can be found in "ctlVal", the command publisher is recognized using the parameter
"origin". For more information about the parameters, see Appendix

Programmable logic control (PLC)
3.5.3
The programmable logic control, (PLC) function can be used to provide user-preferred control
schemes. Several control functions have connection points to enable connections to be made to
the PLC function; they can be used to create user-preferred control schemes. It is necessary for
the user to program the PLC logic that will be used for the particular connection.
Note: The user-preferred control scheme implemented by users can only be operated in
the DIR mode.
