### Which node-red-contrib-modbus version are you using? V5.26.0 Modbus Getter Node ### What happened? Very strange behavior noticed when i deactivate queue command in serial RTU buffered mode For example i have 4 modbus slave devices, in queue mode they all read ok, subject to the queue settings. When i turn of queue command, no matter what the ID is in the modbus getter node it always returns the data from ID1? it seems to be attached the to Unit-id in the server properties just above the Time out (ms), if i set it to 2, then all the getter nodes will read ID 2. If i use the flex getter this behavior doesn't happen, i can read each slave device interdependent. Is it a bug or am i doing something else wrong. Im on node v16 Node red V3.1.9 Thanks ### Server Modbus-Server Node ### How can this be reproduced? Turn of the Queue command feature and try to read multiple slave devices. ### What did you expect to happen? _No response_ ### Other Information _No response_
