Hello,

@Lawrence,

I tried to install node-red-contrib-modbus@0.7.0 with several npm command.
Here error log :

I have same result with :

npm install node-red-contrib-modbus@0.7.0
npm install node-red-contrib-modbus.tgz (.tgz downloaded from website with 0.7.0 version)

and tried these previous commands with –unsafe-perm, –prod and/or –build-from-source

I can see serialport-v4.0.7-node-v11-linux-arm.tar.gz not exist and i don’t know how to prevent this error

Sorry, i made a mistake:

because our nodejs version of Conduit gateway is 0.11.1 and can’t be updated

it’s nodejs 0.10.40 not 0.11.1. The 0.11.1 is the version of node-red. Do you know the nodejs requirement for node-red@0.14.1 (the required version for node-modbus package)

@Lawrence

I checked the following site : https://libraries.io/npm/node-red-contrib-modbus/0.4.8

I don’t know if I can trust it, but from the version 0.4.8 the nodejs requirement was 0.13.4.
Comments above show that we have limitations, because our nodejs version of Conduit gateway is 0.11.1 and can’t be updated :

However, it is not possible to upgrade nodejs beyond 0.10.x due to the Conduit being restricted to the armV5tej instruction set.

In your case, do you remember the version of nodejs and npm that you have used before ? It is nice of you to ask your friends about their versions.

@Peter

I tried to install pymodbus two hours ago. I had some compilation errors but the package pymodbus seems to run.
With your advice i’m going to reinstall pymodbus

[Michael Hance]

Thank you,

I start to implement my solution.

About set up, you said :

pip install pyModbusTCP

It’s only a modbus client, so i replaced pyModbusTCP package with pymodbus package because i need to implement a modbus server on Conduit.

Do you think there will be a problem running if I install the pymodbus package ? Can the Conduit gateway support a modbus server ?

[Michael Hance]

Thank you for this alternative. I thought about a pythonic solution too.

I think i’ll try that. For init script at startup, do you have recommendation about linux folder I need to use to start my python server ?

[Michael Hance]

Thank you for your reply,

I wanted to know if it was possible because in another topic (here : http://www.multitech.net/developer/forums/topic/node-red-nodes-available/#post-13689) M. Lawrence Griffiths said he had managed to use the node-red modbus package. I don’t know what kind of product he used but today i have a MTCDT-210A Conduit and it seems we can’t use this node-red package on this conduit. My use case is : getting datas from LoRa and put them in a ModBus server with node-red. So, i will try to find another solution.
