Rookie, you write:
Sorry if I'm a little vague, I'm a PLC and hmi guy
Being a PLC and HMI, in my books, would mean you would not be vague.
Just to let you know, I do both, PLC/SCADA and micro-controllers, so, feet in both camps on this.
So, I am having some difficulty in understanding what you write.
Are you saying the switches are at one end and the lights at the other end, if not, can you better describe the layout for us ?
I think 30 foot paces would be about 10m, correct ?
Are you wanting any form of control at both ends or only one end ?
What restrictions to the thing that ties the two ends together, such as barriers to cables wires, RF ?
I guess you know in the industrial world of PLC and SCADA, we like to engineer things, but first, a concise and clear description is what is really needed.
