Analog outputs
Analog output as switch
An example for the use of the analog output as 0/10V switch is shown in picture 7.2.5.c
1. set the gain (An.33) to 20.00
2. set X-offset (An.34) to the desired switching level

-100%
Due to the high gain the analog output switches in a relative small switching window.
Calculation of the gain
Since the analog output works always to the specified values in 7.2.4 the characteristic can be adjusted with
the gain so that the total range of 0... ±10V is used.

Analog values for the respective input can be preset in percentage with parameters An.32/An.42/An.48.Value
8: „Digital setting" must be adjusted as process variable. The setting is in the range of ±100 %.
