Khalid Posted November 30, 2006 Report Share Posted November 30, 2006 ... I am not sure how tomake the axle work, which busregisters I should use, ... Hello Harry, Looking at the manual briefly, it doesn't list the Modbus addresses for the parameters explicitly anywhere. However, sections 5.4 and 5.5 do list some examples. In these sections, the register addresses are specified in paranthesis. You will want to contact the device manufacturer to get a complete of Modbus register addresses. Gut gl Quote Link to comment
Harry1984 Posted November 30, 2006 Author Report Share Posted November 30, 2006 Hey Thank you for your help... I managed it to find out the addresses... there is a software tool which handles all the parameters of the axle and in this tool there are all the addresses included. Is there any VI in which I only have to put in the addresses and everything works? Greetings! Quote Link to comment
Olivier Jourdan Posted November 30, 2006 Report Share Posted November 30, 2006 Is there any VI in which I only have to put in the addresses and everything works? Hello all, in my firm, we have implemented ModBus Protocol (over serial and TCP connexion). You can download here an exe demo witch allow you to try communiction with your device... of course, it's not an implementation of NI modbus library, but perhaps it can help you... ciao Quote Link to comment
