If you just need to poll a few holding registers on a PLC to test communications, download the classic ModScan32 from WinTECH (it will say "32" but works fine on 64-bit Windows). If you want a true native 64-bit application without paying, go with QModMaster . Always scan your downloads and avoid third-party "download aggregator" websites. download modscan 64
