A SCADAPack controller's clock can be synchronized from Geo SCADA Expert or another source. To define which clock synchronization method you are applying, use the Set Clock Method field on the SCADAPack tab.
With a Realflo-enabled SCADAPack controller, the options are:
- None—The controller’s clock is synchronized via a source other than Geo SCADA Expert.
- Realflo—Geo SCADA Expert synchronizes a Realflo controller’s clock using a Realflo protocol command.
Ensure that any Advanced Modbus Outstation Sets that contain Realflo controllers have their Broadcast Set Clock feature disabled. (The Realflo method of setting a clock results in a Realflo controller restarting its current Hour log.)
