Analog in- and outputs
Analog output as switch
An example for using the analog output as 0/10V switch is shown in picture 7.2.13.c
1. adjustment of the gain (An.33) to 20.00
2. adjustment of the X-Offset (An.34) to the desired switching level

Because of the high amplification the analog output
switches in a relative small switching window.
Computation of the amplification
Since the analog output always works firmly onto the values defined in 7.2.12, one can adjust the characteristic
with the aid of the amplification that the complete range 0...±10V is used.

Analog values can be preset in percent for the respective input with parameters An.32/ An.37/ An.42/ An.48.
For that purpose value 8: „digital setting“ must be adjusted as process variable. The setting is done within the
range ±100 %.
