I thought i would show a preview of what i have been working on for the last week.
This is revision 0 and is a still a work in progress.
This is my first Mach3 modbus and brain work. So i am sure it can be optimized in the future.

Its a Mach3 Pendant/Remote hosted on my iPad and iPhone.

Solution is based on platform independent SCADA package, and can be hosted on Android or PC (Window or Linux).
Comms at Modbus TCP.

Cash cost was $10 for one screen SCADA runtime for iOS.

Modbus Slave app i used was a free download.

Anyways, i did a video showing it working last night.
I look forward to your feedback. Enjoy!

I was watching your video and really like it.  I am in the process of trying to make a pendant myself with a HMI touchscreen.  Is there any way you could post names of software used and what variables and modbus you used?  I know the CMORE touchscreen wants to be primary to so I would have to try going thru the daigslave server to, but any help would be greatly appreciated.  Thanks.
