MattWebb Posted March 18 Share Posted March 18 Hi, I am new to DAQFactory and Modbus so please bear with me. I extended a 485 network and added 5 Energy monitoring instruments to it, these instruments use ModbusRTU protocol. This network connects to the LAN via a Netbiter. There are dozens of other networks and instruments which are working okay and DAQFactory is displaying and logging the data without issue. I created a new channel to communicate to one of the new instrument and when I set the timing to say 5s then Apply, the data starts to flow in from the new device - Great. The problem is that at the moment the new device start communicating, ALL other channels stop? To remedy this, I set the timing to 0 on the new channel and have to shutdown and restart DAQFactory. Due to the devastating affect that this new channel has to the communications on all the other channels, most of which do not share this rather small physical network in the compressor house, I have to imagine that what I have done must be obviously wrong? but.... on the flipside, the new instruments are passing their new data as expected? Any pointers would be appreciated. Quote Link to comment Share on other sites More sharing options...
