h Analog inputs:
To use analog inputs of the expansion unit, select the
“Service Data Objects” tab and set “Analogue input
global interrupt enable” to “1”.
With the value of “Analogue configuration word” you can
change the configuration of the expansion unit. By default
analog inputs IA1 and IA2 are set to “0 to 10V” and the
analog output is enabled.
