Howto send DRO Axis information?

[poppabear]

Peter,

    Yes, I understand what he was wanting, I was trying to find a way to use the Modulus function in the VB macro pump so I could seperate the Whole number and the remainder number and put them each in thier own register. Then send those two values out to two seperate user registers, then combine them back with a "Addition" block at the target device.

   I just have been to buzy latley to really spend the time trying to get his numbers seperated and sent out.
BTW: Thanks for you most excellent explaination of the Modbus info.

Another option you may be able to Use Bit masking techniques to sperate out the two parts as well, then send them sepratly also.

Hi,

it takes only a few minutes to show the DRO on LCD via modbus.
But what you see is only a screenshot of the LCD-Simu because i'm not able to program
SPI on my PLC :-(

in the background Mach3 and foreground my notebook with simulated LCD of the PLC:

^^ Could you share the cubloc code to do that?

i sent DRO position via macropump and serial port on Lcd.
but i decide use Modbus ,similar "jimmybondi"
Please explain .this thread remained without conclusion.

this is solution.
we can send each axis via modbus with 4 register(4 byte)
2 byte for int and 2 byte decimal
up 65536.65536
i think is enough
