Frequently Asked Questions

Open All
Close All
What modules are supported in the Logix SIS redundancy rack?
Chevron DownChevron Down

All modules that are supported in standard 5580 redundancy are also supported in Logix SIS with the substitution of 5580 ControlLogix® Controllers → 5580 GuardLogix® Controllers. P controllers are not supported in Logix SIS initial release.

What safety I/O is supported with Logix SIS?
Chevron DownChevron Down

Only FLEX 5000® safety I/O modules are supported in the initial release.

Do both controllers connect to the I/O?
Chevron DownChevron Down

Logix SIS makes use of concurrent communications from the safety task meaning both controllers send data packets to the I/O modules through the adapter.

What SIL level is supported?
Chevron DownChevron Down
  • The system can achieve up to SIL 3 when synchronized.
  • SIL 3 is maintained on disqualification if repaired within the Mean Repair Time; otherwise, the system degrades to SIL 2.
  • The system can achieve up to SIL 2 when it is not synchronized.
Can I use a P controller in Logix SIS?
Chevron DownChevron Down

No initial release requires the Logix SIS system to leverage the Red safety controllers.
