Title: Checking primary and secondary cores are functioning on SC050
Post by: jashom1 on June 16, 2015, 06:39:21 AM
Hi,

Due to the outcomes of a risk assesment, we have determined that we need to check to see if the primary or the secondary core are responding and functional.  My question is do I need to go as far as exchanging an RS232 message between the cores, or can I just do a simple check with the SafetyLayer bus on the signal "Failure" to determine if it's zero or not, then disable outputs based on that?

Has anyone done any examples?

Thanks!

John.
