Parameters
P642 Operating
mode AO1
Here you can set the operating mode of the analog output. The following operating
modes are available:
•
OFF: The value zero is always output.
•
0 ... 20 mA: Output of the value of the reference values as current values 0 ... 20 mA
at AO1. P641 Scaling AO1 will be evaluated as an absolute number.
•
4 ... 20 mA: Output of the value of the reference values as current values 4 ... 20 mA
at AO1. The slope of the characteristic curves is flatter than in 0 ... 20 mA. The char-
acteristic curve has an offset of 4 mA and the absolute of P641 Scaling AO1 refers
to the value range of 16 mA.
