I don't know what A-B offers, but there are numerous wireless modems, either serial (RS-232/RS-485) or ethernet that replace a communications wire cable.

There are consumer ethernet (WiFi) or industrial 900 MHz freq hoppers.

Antenna placement can be critical with wireless, so using 3rd party wireless modems offers a wide choice for modem placement, antenna placement, technology, whatnot.

B&B has wireless, so do dozens of others.

Phoenix Contact would be another good source.

What kind of HMI are you looking for?  Something portable like an iPad or a laptop?  Or something like a panel-mounted HMI?  

thanks for all yours helps.Yes I looking for something like a compact hmi or ipad that I can move around the machine.I have a panelview 1250 plus but is fix to the machine.This hmi will be only for maintenance preventive or to adjust some station that is far from the panelview 1250.Thanks again for all helps to me.

Siemens has one, it has drivers for A-B available, but at least one version was pulled from the market recently. I don't know if that was permanent or a manufacturing glitch. They are still selling the tethered version, it was only the wireless that was pulled, it may have been the one they marketed as "Fail Safe" that had been qualified for SIL3 Safety applications. I always questioned that capability, I would never use something like that as an E-Stop. It may fail safe, but it may fail safe too often. If you are not going to try to do Safety programming with it, I'm pretty sure it's still available.

I'll try to find out and post back here tonight.
