sgull Posted February 6, 2013 Report Share Posted February 6, 2013 Hi all I need some help in setting up a 485 Modbus communication. I have several power meters with 485 outputs. By using the communication example I can set up 1 meter and obtain the readings. My problem is how do I communicate with all seven. Do I need to set up a modbus configuration for all meters and if so what will be the network ID in each. How do I initialise them, a single one is initialised with a power up bit after the com init block. No matter what I do I seem to loose comms on the one that is running. If someone has done this before I would appreciate some help. Regards Denis Quote Link to comment Share on other sites More sharing options...
