Switching Digital Outputs Based on Thresholds


The digital outputs of connected I/O systems can be switched depending on measured values or states. In this way, heat pumps or relays, for example, can be controlled by specifying a defined output. A tolerance (hysteresis) dependent on the selected operator prevents the digital outputs from switching even with slight power fluctuations.

Tolerance

Greater than or equal to (>=)

1 %

Less than or equal to (<=)

1 %

Equal to

5 %

The following limiting values and parameters are available:

  • Alarm in case of warning or error

  • Alarm in case of error

  • System active power

  • System reactive power

  • System active power at point of interconnection (grid feed-in)

  • System reactive power at the point of interconnection

  • Reactive power setpoint

  • Setpoint of active power limitation

  • System-wide state of charge of batteries (SOC)

  • Active access through direct selling

  • Mean or peak value of the 3 voltages at the point of interconnection (depending on activation and settings of function Q(U))

Requirements:

  • All devices in the local network must be in operation and connected to the product via an Internet router.

  • All devices must support the Speedwire encryption.

Procedure:
