Current behavior
Using ‘Modbus Flex Connector’ and ‘Modbus Flex Getter’ returns warning: FSM Reset On State {"value":"failed","actions":[],"changed":true}
. The injected Payload to ‘Modbus Flex Getter’ is:
msg.payload = {
'value':msg.payload,
'fc': 3,
'unitid': 1,
'address': 24 ,
'quantity': 1
};
return msg;
What does the warning mean? Is it serious?
I do not get any Modbus output.
Expected behavior
No warning.
Minimal reproduction of the problem with instructions
- Connect Inject, function Node and Modbus Flex Connector
- Connect Inject, function Node and Modbus Flex Getter
- Inject to Modbus Flex Connector, then to Modbus Flex Getter

Try to set queue to 10 ms (with commands queue checked), applied to all the flow. Then delete all the modbus nodes. Then deploy. If ok ==> add one modbus flex getter/flex write (it’s preferred to use only these two nodes). Then deploy. If ok ==> add all the other ones. Good look.
Issue disappeared!!! I don’t know why… Just gamed with queue , and ,after deleted the three Modbus flex getter buttons, put it a new one, and OK!!! bye.
