I would like to read from Mitsubishi PLC Q Series by using MC Protocol nodes. However, connection error for the MC Protocol nodes. Anyone got similar issue and know how to resolve?
Ethernet type : Built-in (Q03UDVCPU)
PLC IP Address : 192.168.3.39
On Q series, for reasons I have long forgotten, you need to use UDP -> passive -> procedure exist and enter port numbers.
Alternatively, just connect to the Auto Open UDP port 5000 (no PLC config required)
Settings on the Node-RED MC Config node would be something like:
Depending on the PLC, you might need to use 3E (but 4E is better, faster, safer, use that if it works)
Already try but still not working. An error stated as the picture below.
Are there any potential issue with the nodes?
The util.log() API has been removed in Node23 or 24.

What should i do?
Install an older version?
Yes, or ask the author of the node to support Node24.
Install Node 22 or Node 20 for the time being
I am in the process or updating the node but it wont be ready for few weeks due to vacation.
