How Do I Use DI Ports?
- The SmartLogger provides four DI ports, which support DI active scheduling, DI reactive scheduling, DRM, remote shutdown, and input of correlated alarms.
- For details about DI active scheduling, DI reactive scheduling, DRM and remote shutdown, see Power Grid Scheduling.
Before setting the corresponding function, ensure that the DI port is not set for other purposes. Otherwise, the setting will fail.
Alarm Input
When a valid level is delivered into a DI port, an alarm is raised. You can set the alarm name and severity.
- Choose and associate alarms with DI ports.
