SBO modes are available depending on the configuration selected by the user.

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

†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

MICS, PICS, PIXIT and TICS
