Hello, I am new to Labview. I need to trigger the stepper motor to start by allowing current to run through the motor. This can be done by turning bit3 on the16 bit register 007Dh. The register address has been attached below as 007Dh.png so please view that before you go any further to have a better sense of what i'm trying to accomplish. Please also note that the decimal conversion of 007Dh is 125. So my question is, how do you turn on bit3 of that 16 bit address? How would you translate the holding registers from the manual into a 5-6 digit data item that labview can understand? (Please refer to this page for the types of data items: http://zone.ni.com/reference/en-XX/help/371618J-01/lvmve/dsc_modbus_using/)

Hello Missso

While we are analyzing what could be happening with your set up, you could test the Modbus Library... here you can find it.

By the way, what version of NI VISA do you have?

Regards

Frank R.
