Hi, first of all I want to say that I'm new to Labview, so I'm in the studying phase and I may have very basic questions. There's a tool that's basically a big screwdriver with a controller that can be programmed to make certain jobs using desired speed and torque, it's called Handy2000. You can save in different channels the configurations for the different jobs. The controller has its own software, and I can already connect to it and read/write with no problem using an ethernet cable. I was asked to make an interface in labview to select the channels, show in a graphic way (with photos of the electronic components) what screws correspond to that channel, and show when the steps of a job are done. All of this will be in a panel pc connected to the tool's controller. Since I'm new to labview and to the modbus protocol, I took some time to study the basics. I understand how the protocol works and the very basics of labview programming, so I have an idea of how the front panel will be and what things needs to be modified. But now it's time to start the implementation, and I'm a little lost on how to make the basic configuration to setup the connection and start writing the addresses on labview. By the way I don't have the DSC module, I only have to use the NI Modbus library. I already checked the example functions to use my pc as master and slave and watched the codes for the different type of data (coil, input, input register, holding register), but I don't know how I should start programming, and the most important thing is how to make some tests in the process to check that I'm having the communication between the pc and the controller. I already read in the forum and learned a lot, but failed to see as a completely newbie how to make and change the basic setups to make the thing work. So any help is welcome, specific answers about how to make the basic setup and how to test it, vi examples or basic tutorials to read. Thanks in advance, Stefan Christiansen p.s: I attached the manual that specifies the addresses for the modbus communication, so if you could give me an example of where I should change the address in the labview code and what should I put to make a basic read or write it would be very helpful Estic Touch Panel Comm.
