Add DRO for rapid feed rate override

[ostie01]

Would like to add a DRO for Rapid feed rate override.

On my pendant, I have a 3 positions rotary switch that I would like to use to set rapid feed rate to 25%, 50% and 100%

I use 3 inputs on the ModIO, no analog input available.

If for example, the switch is on position 25%, would like to write that value to that DRO, and so on for 50% and 100%.

I have tried to write a brain but stuck with it.

Is someone have any idea on how can I do that or any clue would be really appreciated.

I already set up a Spindle speed override, feed override and the third analog input is for the MPG selection mode.

Any idea what the input format is in a Brain for the ModIO? Afraid I dont as I have never used one but the rest is easy enough.

That is the ''easy part enough'' that I have problem with.

I don't know how to do it with brain.

Do you know what form the ModIO inputs are in a Brain. I know what the Brain needs in the Modbus ranges for my PLC but the ModIO will likely be totally different.
