Title: Decimals when sending DRO's via MODBUS
Post by: Triblix on July 16, 2012, 06:31:22 AM

Good afternoon,

I am sending the X-axis reading from Mach3 via MODBUS, but I am only receiving the integer part of the value.

For example, my x-axis position on Mach3 will be displayed as '+108.2145', but on my SCADA controller it is only displayed as '+108' without the decimals.

How can I overcome this problem so that the decimals will also be displayed?

I have tried using 2 registers in Mach3 when sending (i.e 32bits), but this still did not solve the problem.

Thank you for the assistance.

Kind regards

Multiply by 10000 before sending and divide by 10000 at the other end?
