dshha Posts: 31 Rating: (1)	Can someone help me identifying the reliability of below IO modules... 1) Digital Input module : 6ES7321-1CH00-0AA0 2)Digital Output module : 6ES7322-5HF00-0AB0 3) AnalogInput module : 6ES7331-7NF10-0AB0 4)AnalogInput module :6ES7332-7ND02-0AB0 These will be part of non-redundant ET200M with S7-412H CPUs. Are they >99% reliable??? I guess these will need MTBF data and from that we can take it further... Thanks in advance for responses.
