PLC Logic Sync In Soft Switchover Application.

[Arun Kumar DaraParticipantKarma: 28Rank: Padawan]

Hi,

I’m using 2 compact Logix PLC’s for a soft switchover application. I was able to sync my data variables like setpoints, scaling values, etc using message instruction.

Now I want help to understand how to sync PLC logic also.

Thank you,

Hi Arun,

I’m just trying to wrap my head around exactly what it is you’re trying to do? I think what you’re asking or suggesting is that you want to have two identical controllers independent of each other running exactly the same logic in perfect synchronicity. You goal is this, in the event one controller fails, there’s an automatic fail-over to the second controller without any kind of interruption. Am I correct?
