2 Common Specifications of IAG Executing Comparison of NX-series Safety Control Units IAGs access the latest backup data to read out the safety signature from the Safety Unit restore file of the NX-series Safety Control Unit. They also read out the safety signature of the validated program in the NX-series Safety Control Unit. After comparing the two safety signatures, the IAGs display the verification result.
