khekd Posted January 10, 2007 Report Posted January 10, 2007 Here is the code example for the modbus master. you will have to read the rung comments very carefully because those are the only help files. And you have to view them in STL to get all the detailed comments. It is doable because I have several people using this to talk to VFDs and weigh scales. Good luck! Modbus_master.zip Quote
