Precautions
• When the measurement unit time for the measurement target is shorter than the scan time, the measurement may not be
performed properly. Adjust the measurement unit time to twice the scan time or longer.
• If a module error occurs after normal completion, this FB does not output error completion or module error. To check for
module errors, use M+FX5-2HC_ErrorOperation (Error operation).
