Multiples devices ?

elbar posted a comment on ticket #112

Hi Cristian. Thanks for writing in. It is a little difficult (I will need to refactor the code). For now I think that you can start multiple instances of QModMaster and connect to multiple slaves (only for Mobus TCP). Best regards

TCP connection fails for delayed connections

elbar posted a comment on ticket #94

Hello again I haven't worked with Arduino. Many times the slave (in your case the Arduino Uno) disconnects the master if it does not get any read/write request in a specified timeout. So you have check your device settings (for example timeout or something like that). Best Regards

Hello again. Unfortunately the fastest scan rate that QModMaster supports is 1000ms. Can you please try using a Modbus Master program that supports fastest scan rates ? A very good one is https://www.modbustools.com/modbus_poll.html Best regards
