Mitsubishi Q Series Node Red Help

[Steve-Mcl]

Here is a working example...

Note the UDP MC Protocol + Port Number...

NOTE: As with many things mitsubishi, you might need to power off/on the PLC for the settings change to take effect.

Lastly, regarding reading data from mc protocol...

We tend to arrange ladder to put all items of interest in one contiguous data block (e.g. D1000~D1199) then read all 200 WORDS in one go

Then I use another node called buffer-parser to convert all the WORD values into nice data.

Reading all required data in one hit has the following advantages...

1. Much faster reading 1x200 items than reading 200x1 item
2. Consistent data (e.g. all data is read on the same PLC scan & are consistent to one another)
3. Converting the WORD values to nice types in one go in a nice easy editor

e.g...

EDIT...
Dont forget to read the built in help - especially the details about the format of the PLC address...
