I am looking to use the AWB3300-B (Anybus Wireless Bridge II) in an industrial environment. I want to use it as a cable replacement to talk between to Allen Bradley PLCs. Our goal is to pass some INTs and REALs between processors. We did some testing in both wifi and bluetooth. Wifi was giving us lots of communication losses and bluetooth was a lot more reliable. So we are set on bluetooth but it seems that the range for bluetooth isn’t as good as wifi. I read the Anybus whitepaper on “Wireless technologies for industrial communication” and the anybus manual.
With all that being said, I have some questions and hope to improve the performance of this wireless bridge.
- Are there any settings on the device’s webpage (192.168.1.99) that I can change to improve and optimize performance? Our application is 1 master and 2 slaves but normally only 1 slave will be active at a time. Constant connection is the priority, speed is secondary.
- How can materials effect my signal? Structural materials around these devices will be metal, concrete, and maybe a wood floor. Does wifi and bluetooth behave differently since they are at different frequencies?
- How can I optimize the mounting orientation of the anybus so the antennas are best utilized? We won’t be able to have the “face” of each unit pointing at each other all the time. Does wifi and bluetooth behave differently since they are at different frequencies? For example, what if both antenna’s point up to the ceiling or both pointing at the floor. How will that change the signal strength?
