3.5.1 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.
3.5.2 Remote control
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 or 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 IEC61850
MICS, PICS, PIXIT and TICS .

3.5.3 Programmable logic control (PLC)
PLC function should be used in order that user can have preferred control schemes. The user
can find several connection points to control applications in the functions. Automatic sequence
control (ASEQ) function is required in order that the user-preferred control scheme will start,
as shown in Figure 3.5-2.
