It needs a little extra to meet PLd/e, no? I usually work with Allen-Bradley, my Siemens experience is rather lacking.
Most of our customers would run away screaming from anything that's not hardwired safety, and are too cheap to shell out for a fully-blown safety PLC like the GuardLogix.

Most maintenance people like hardware solutions because they are more easy to bridge ... With a software solution you can show easy for each safety button/switch a message on a display. Do it with a wired safety.
