• Stop counter
Specify the upper flow limit for counting. Flows above this value are ignored during
counting.
• Invert
Specify whether the switching direction of the relay should be inverted. (Factory setting:
No).
• Error handling
Specify the behavior of the relay if an error occurs.
9.4.9 Configuration of a fieldbus relay
A fieldbus relay (DO relay) switches according to a binary value (e.g. from a PLC), which is
present at the DO Block of the device. The fieldbus relay can then be switched
independently of the measured value - as in the case of a remote IO unit.
1. Navigate to Relay/controls → Relay configuration → Relay allocation → Relay N →
Function → Select function
2. Select the Fieldbus option.
3. In the Function parameter, select the DO Block which the relay is to be connected to.
9.4.10 Configuration of the DI Blocks
Parameter set
Output/calculat. → Digital input → Digital input N
Parameter
• Allocation
Select the switching state that is output as a binary signal via the DI Block.
• Relay
Connects the DI Block with one of the device relays.
Once this option has been selected, the Relay function is displayed where you can
select the relay.
• Pump control
Only displayed if pump control has been configured.
Connects the DI Block with a pump control relay.
• Rake control
Only displayed if rake control has been configured.
Connects the DI Block with a rake control relay.
• None
• Value
Indicates the current switching state of the relay.
• Status
Displays the status that is transmitted together with the binary value.
9.4.11 Configuration of the AI Blocks
Parameter set
Output/calculat. → Analog input → Analog input N
Parameter
• Measured value N
Select the measured variable which is output via the AI Block.
• Value
Displays the current value of the selected measured variable.
• Status
Displays the status that is transmitted with the value.
