Where does the industry stand with bluetooth or wireless communications?
Is it reliable for data collection to a server?
Our production area is roughly 11,000 sqft with a nice low ceiling of only 15ft, 220V and 480V buss lines running the length of the production area in multiple spots, 34 machines with 22 hydraulic pump motors (20-30hp).
Plan was to run network cable to all the machines, but it would be amazing if i didnt have to do that lol. But also can deal with loss of communication to the server from the wireless not working properly.
Any experience out there?
We use a phoenix wireless system to send status from a moving tripper to a base station, ranging from 10 - 800 feet. There are 5 small (<5 HP) VFD driven motors on the tripper.
The phoenix system runs a version of wifi, and we have not had any issues. It has been in service for about a year so if we run out of hard-wired cabling for control, we MIGHT use the wifi for control. But we are a bit paranoid!
There is a festoon system on the tripper that carries power, 3 phase motor cables, and 2 control cables. We could not find fiber rated for festoon ... 800 feet is longer than cat5 copper will go. All control and most status was hard-wired in the control cable, but we there are additional status (motor currents, individual status for multiple hard-wired stops to aid in trouble-shooting, analog level detection below the tripper) going over the radio system
Personally I would hard-wire what you need to keep the place running, and try out wireless for the data collection that is nice-to-have ... details on vibration, bearing temperatures, chattering switch status, etc.
Putting in a wireless system that large will take some time, and you may need to add wifi points to get good signal around big metal machines. When you add some equipment later, it may break what you have running until you figure out where to add a wifi point. Wifi signal reception, network design, and actual signal received ... is still Voodoo in my mind. Some of it works perfectly, some of it has gremlins.
A good start is to buy GOOD equipment that is WELL SUPPORTED by a local company that can help you when it goes wrong. Phoenix has been responsive to issues, as has EECOL electric, our local distributor. We got a demo system for proof of concept, Phoenix and EECOL assisted with design, initial setup, etc. They saved me many hours of frustration.
While the system has proven reliable. I would still be cautious deploying a system the size that you are talking about.
