Commissioning Deltabar PMD75B PROFINET with Ethernet-APL
54 Endress+Hauser
Example: Outputting of the flow value at the current output
In the following example, the flow value should be measured and output at the current
output.
• Perform position adjustment if necessary
• Output the flow signal 0 to 100 m
3
/h as a 4 to 20 mA value
100 m
3
/h corresponds to 30 mbar (0.435 psi)
Menu path: Guidance → Commissioning
• In the Assign PV parameter, select the Scaled variable option
• In the Pressure unit parameter and Scaled variable unit parameter, select the desired
unit
• In the Output current transfer function parameter, select the Square option
• Pressure value 1 parameter / Scaled variable value 1 parameter
Enter 0 mbar (0 psi) / 0 m
3
/h
• Pressure value 2 parameter / Scaled variable value 2 parameter
Enter 30 mbar (0.435 psi) / 100 m
3
/h
Proceed as follows if the flow does not have to be displayed as a measured value and only a
square root extraction should be output.
Menu path: Guidance → Commissioning
• In the Assign PV parameter, select the Pressure option
• In the Output current transfer function parameter, select the Square option
• In the Lower range value output parameter, enter 0 mbar (0 psi)
• In the Upper range value output parameter, enter 30 mbar (0.435 psi)
