Hi. Did anybody knows how to simulate analog values in WINCC !! For example,i have NH3 sensor with range 0 - 14 mg/l . I scale this input (4 - 20 mA) with step7,and i need simulation for this in WINCC ! This is a school project,not real !!! Is this posible to simulate,or how to force WINCC 2007 flex to display some values in that range,0 - 14 mg/l . Thanks.
