andybdjuk Posted December 6, 2008 Share Posted December 6, 2008 Hi, i have just bought a solar control regulator and found it can be connected using MODBUS. I know very little and have been playing. With the below i have followed the DAQFactory Manual but im not receiving any data. I dont understand all the options in the I/O Type. With the information below are you able to point me in the right direction to get some meaningful data, for the example below of Battery Voltage and help start my new learning curve. I have attachect my channel setup Thanks Andy FROM THE MANIFACTURES MANUAL The TriStar supports RTU mode only. 16bit MODBUS addresses (per the modbus.org spec) The serial communication parameters are BPS: 9600 baud Parity: None Data bits: 8 Stop bits: 2 Flow control: None All addresses listed are for the request PDU. The TriStar defaults to server address of 0x01. Variable_name [Logical Address][PDU Address] (Units). Short description. Definition. adc_vb_f [0x008] (V). battery voltage, filtered. Voltage measured directly at the battery connection on the TriStar. MODBUS_Test_1.ctl Link to comment Share on other sites More sharing options...
