When I was a control engineer working in utility plant 10 years ago (time flies ), every year, I have I/O expansion projects which I need to budget the cost and time at least 2 months earlier....
Why? -- schedule & resource planning, hot work permit, scalf folding, ceiling climbing, process hold coordination, etc...
All this hussle seems to go away with Wireless I/O technology...easy and fast...connection in minutes and the best part is...any I/O type!!

While Wireless technology has been providing huge time and cost saving, there will be a new 1410 Gateway which significantly reduce the total cost of implementation for small I/O projects!
