Hi, The SIMATIC STEP 7 V16 brings many news features, one of these are the new instructions Filter_PT1, Filter_PT2 and Filter_DT1. In a simple way, Filter_PT1 and Filter_PT2 are low pass filter (1st and 2nd order) and Filter_DT1 is a high pass filter. The could be used, for example to filter analogic signals. TIPs:
PT1 "Filter_PT1_DB".Gain: proportional gain "Filter_PT1_DB".Lag: lag time constant in seconds PT2 "Filter_PT2_DB".Gain: proportional gain "Filter_PT2_DB".TimeConstant: time constant in seconds "Filter_PT2_DB".Damping: damping ratio DT1 "Filter_DT1_DB".Td: derivative time in seconds "Filter_DT1_DB".Lag: lag time constant in seconds I place, attached, a sample program and a printscreen of these filter in action with their default values. You can change these parameter, in the sample project by the watch table.
