8.8 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.
Operator Tolerance (hysteresis)
Greater than or equal to (>=) ± 0.5 %
Less than or equal to (<=) ± 0.5 %
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.
Procedure:
