CPU-H and Failsafe IO Cards

Hello everyone,

I'm wondering if CPU 41x-H can be used with Fail safe IO cards?

I mean can I load Failsafe function blocks in an H CPU?

The problem is that my company has baught some Failsafe IO cards with CPU 414H.

Have you any idea if such configuration work together and do failsafe IO cards function failsafe?

Thanks in advance.
