Direct Control / SBO
- SCADAPRO
Direct Control / SBO |
CO (Control) Type of IEC61850 cannot control by the MMS Write method. Instead, it requires another control method, such as Direct Control or SBO, which can be managed through DriverCommand in UltimateAccess Web 1.0.
Command | No. | Example |
|
|---|---|---|---|
Set | 11 | DriverCommand(“{Driver.Station}”, 11, “{CO}”) |
|
Operate | 12 | DriverCommand(“{Driver.Station}”, 12, “{CO}”) |
|
Cancel | 13 | DriverCommand(“{Driver.Station}”, 13, “{CO}”) |
|
Use Direct Control |
CO type with Direct Control can be written successfully using ‘Operate’ command after ‘Set’ command.
After activating ‘Set’ using DriverCommand 11, if change CO type tags and then use ‘Operate’ using DriverCommand 12, CO type data will be updated.
Use SBO |
SBO can also be controlled in the same way as Direct Control, following the sequence of Set → Operate. The difference is that the Cancel command can be used with CO types set to SBO. It is used to revert any tag value changes made after Set and before using the Operate command. Using DriverCommand 13 will reset the modified tag values to their initial state.
