We think there are a few switches that are switching on and off faster than we can monitor normally. Is there a Siemens version of a histogram in Step 7 where we can monitor the switching of inputs?Thanks, Danville Dan

Two well known options are: 1-PLC-ANALYZER pro 5 2- ibaPDA Wincc from SIEMENS also provide data aquisition of at least 500ms in normal cases(e.g in S7300).If I do not have those Softwares I assign a counetr for each of switches(N.O) and monitor the values.If you switches are N.C use a Not command before the counter.
