hey all,
i've got the siemens step7-200 cpu 222 & the analog to digital extension EM 231 and i've a task to do which is to measure the voltage and current flowing in my local network of electricity and to draw their wave forms which needs very high accuracy as the frequency in the network is 50hz which means that 1 cycle of the voltage wave form takes 20msec. and we need to get all the points within 20 msec. so any help!!!???
