Modbus - How precisely works
#4
Currently I am testing communication with recuperator. And I have such variable:
Code:
3x0066 Manual boosting time Manual boosting time / delay (min) Holding register R W 0 - 60 30


This is my configuration from profile:

Code:
{ "bus_address": "14/2/157", "bus_datatype": "uint8", "type": "register", "datatype": "uint16", "address": 66, "name": "Manual boosting time", "units": "min"},


And of course object exists.


But when I try change the variable in LM it is ok, because object changes and stays changed after update. But when I've check this variable via Read test it has value 26. Strange is that LM doesn't update value when it recognize that device has still another. My current setting is 10s interval. There are a lot of errors(what is strange because on read test device responds 100/100 but I unfortunately that see this is normal) but not every interval but only sometimes which after a few hours looks terrible.
Done is better than perfect
