Import of a Technical Question of a not registered User 

Guest

Hi,

The following Siemens components was part of a purchase package from a sub-vendor.

• CPU: 6ES7 412-5HK06-0AB0
• Input Card: 6ES7 326-1BK02-0AB0 
• Output Card: 6ES7 326-2BF10-0AB0 

The sub-vendor has not provided SIL documentation for the relevant components. Is it possible for you to send over SIL documentation with at least the following information:

• Failure rate per hour for undetected dangerous failures 
• Safe failure fraction (SFF) 
• Mean time to repair 

 regards 

Hello;

You should be able to find most of the information you are looking for in the following liks, even though Siemens does not provide up-to-date tables of all your required data:
