Hi

I want to send axis position command values via modbus tcp to a plc and then using canbus to a servo controller. The modbus part is not a problem , I can set it up to work with int or bool but the values im looking for are floats .
Is there any way to convert the x ref cmd to integer or is there already a value thats not a float ?

multiply the float times a factor of 10 (determined by the number decimal places of accuracy you need. Then input that into classic ladder.
