Virtual Commissioning communicate safety signal with OPC

Creator

Hello,

 

Some one of you have any experience in OPC communication for safety signals? As you know everything is perfetct with stndard signals but when we consider safety signals everything is more complex. In general the PLC doesn't allow the communication for safety with OPC (so Process simulate). With Siemens PLC you can solve the problem  using Simba (simulationUnit) but with other PLC brand as Rockwell? Do you know if tehre are some OPC able to force the safety signals?

 

Thanks

Roberto

  1. AB doesn’t allow to trigger safety signals directly by OPC..For AB-Rockwell there is an official workflow, from Rockwell on how to handle Safety signals triggered by normal signals.
  2. Please look at

thanks for your reply.

I know this method but I was wondering if also other approaches exist, if for example I already have the PLC software I need to spend a lot of time to re-map all the safety tags to standard tags.

 

Thank you
