maxx2000:

I am building a control now and would like to add some buttons to the front panel.  I can understand how you wire buttons to existing input terminals on the control, but you said that your panel buttons duplicate the buttons on the control display.  How do you wire these buttons?

Neat Stuff / in a flap at Farnborough
« Last post by BillTodd on Today at 01:46:23 PM »
I've just got back from a trade day at Farnborough air show .  There is the usual small booth BS that accompanies the preiphery of the aircraft business   - 100's billions of currency units changed hands this week, so there's always some thing to pick up, business wise - even I have found myself designing machines to make bits to fit sub assemblies , for assemblies that eventually find there way on to an aircraft. Among the smaller booths this year was a couple of guys with a completely off-the-wall idea that caught my eye and I think might interest you lot here:

a propulsion system based on a ducted flapping wing!

I did 10 years of S5 and S7 and always needed some support manauals! No matter if the printed probram was only 150 pages of ladder/blocks or 10x that, there were plenty os stuff.

Simple I/O signal is possible to debug without commented program, but when it has plenty of internocks and sequences, it will become easily convoluted. Many alarms and interlocks are grouped toget as flags and those would be nice to have commented.

How does a farmer get to be an experienced Mechatronic engineer? You are very good at this troubleshooting.

Nice work. On the whole lathe project. When I made the built up, steel, T-slot table for my little 7x12 chinese lathe, I also epoxied the parts together, in case the screws work loose.

A major engineering project Steve!

Are you having the concrete delivered or doing it yourself? That's a lot to mix and place
