Correct communication format #6

Closed FrantaD closed 3 years ago

FrantaD commented 3 years ago

Hi,

I am testing communication between PLC NX102-1100 and RPI with NodeRed.

PLC NX102-1100:

IP: 192.168.250.10/24 (port 2) FINS node address: 10 FINS/UDP port number: 9600 Memory settings: DM enable Global Variable: TestFins - INT - %D0 - retain

RPI NodeRed:

IP: 192.168.250.11/24 Connection Node properties: image

Connect FINS:

This is how I set it according to the help and it doesn't work. image image image

And this is how it works, but only the connection. Disconnection does not work. image image

Q: How is it supposed to be right?

Write data by FINS write:

image image image

Q: What is the correct response format for one INT variable.

Thank you for your help Frantisek

Hi, please tell me ... node-red version (visible on the node-red menu) nodejs version (run node -v)

This is how to read a value... image

Thank you for the example I have already discovered my mistake.

Thank you for the example I have already discovered my mistake

So this is now resolved? Can we close this?

Notes (for anyone else reading)...

Explanation of the the problem @FrantaD shows... image

when writing values, you should choose number type... image

FrantaD commented 3 years ago

The connect and disconnect commands still don't work for me, but I don't seem to need them.

The problem was solved for me and it is possible to close it.

Steve-Mcl commented 3 years ago

Yes, that does appear to be an issue.

I will leave this open until I fix it (but as you say, it makes no difference - the node auto connects, you simply cannot issue a disconnect)

TBH, I think I copied that text in the help from my Mitsubishi node (MITSI comms (in my experience) have been terrible (especially TCP) and the disconnect/connect capabilities were important. Omron connections seem to works for very long periods without issue)

Steve-Mcl commented 3 years ago

@FrantaD fixed in new version 0.3.1

Thank you for taking the time to report the issue.
