Modbus Poll Connection Failed 4,4/5 5968 reviews

Hi Nick,as I had written in my previous issue, during run time the system generates constantly messages. Openhab is constantly polling for new information. To simply change the interval manipulate modbus:poll (e.g. Modbus:poll=3000 for once every three seconds).' Requested data were. collected from the slave':how do you know?the order of the readout of the data is not always the same and is started at different time intervals. Is this correct?About which readouts are you talking?.

If you'r talking about the registers from to - those should be in a row. If you set up more than one 'modbus:serial:slave' instances the poll interval should be the same, nevertheless they do not necessarily have to be in the same orderYour log shows me a failing connection establishment, with a never give up strategy. I'm not sure if I get your point?
