With most advanced driver setups, ClearSCADA is the SCADA master. However, some drivers support slave functionality, whereby the ClearSCADA system acts as an outstation or similar device and reports any data changes back to its SCADA master (see Master-Slave Communications).
On systems on which ClearSCADA is a slave, the driver’s Slave outstations support a combination of these status attributes:
- Id
- Full Name
- Type
- Created—(New Slave outstations only)
- Last Modified
- Configuration Change CRC—(Only displayed if this feature is enabled on your system)
- Exclusive Control User—(Only Slave outstations that are under Exclusive Control)
- Alarm State
- Alarm Last Updated
- Comms State Alarm
- Channel State Alarm
- Protocol Alarm—(Displayed when supported by the driver)
- Scanner Command Alarm
- Alarm Count
- Source Name
- Source
- Network—(Network connected Slave outstations only)
- State
- Last Updated
- Quality
- Current Channel
- Comms Statistics
- Last Polled
- Point Statistics
- Telephone Number—(PSTN Slave outstations only)
- Preferred Channel—(Slave outstations for which a preferred PSTN channel is specified)
- Incoming Calls—(PSTN Slave outstations only)
- Outgoing Calls—(PSTN Slave outstations only).
For information on slave outstation status attributes that are not listed above, see the driver-specific documentation.
