MicroLogix 1400

Hi all,

I have a problem, when I am on line with the Clients Windows 10 laptop to a Micrologix 1400 Remote run ,  I am suddenly thrown out (Offline) . I tested the communications  with my windows 7 laptop and the results were normal, no communication loss , even with a continuous ping while on line. I am using RS500 version 11 and RS Linx Lite 3.900 CPR 9 SR 9. I have checked Compatibility with Rockwell and all versions are compatible with Windows 10. Any Ideas?

So, if you are doing an OPC DA connection to RSLinx on the Windows 10 PC you may be getting impacted by the Meltdown and Spectre Vulnerabilities that Microsoft sent security updates out. These would have happened on or after 1/3/2018. These updates broke most OPC Classic processing. Microsoft release updates to these to fix the breaks last Friday.
