Can not download modification hardware configuration CPU 414-5H

Hi Expert,

I have a problem when I try to modification HW (change 1 AI module from 2 wire type to 4 wire type) and download to existing CPU 414-5 H redundancy. After successful compiling, I downloaded and have this massage: "the safety attribute on the module cannot be overwritten by a configuration that does not have a safety attribute. the download will not be executed".The existing CPU already have had password also.

 Thank you.
