Hello, I've problem with Modbus. When I install node-red-contrib-modbus it show me red alert in Manage palette where I find all installed nodes. And when I use Modbus Flex Getter it doesn't work. I also send my flow to friend and it works on his PC, so I believe the problem is that red alert. I also reinstall it but it still show the red alert.
Is here someone who knows what's the problem?
When you start Node-RED, what version of node-RED and nodejs does it report?
Also are there any errors reported?
Node Red version: 0.19.5
Node.js version: v6.10.3
When I try to use Modbus Flex Getter node I've got two errors
"SyntaxError: Unexpected token function"
"TypeError: Cannot read property 'registerForModbus' of null"
Any ideas what could be wrong or what should I do?
and what version of node-red-contrib-modbus have you installed?
You can check what version you have installed in the manage palette part of the node-red menu
node-red-contrib-modbus: 4.1.3
Is that a problem?
Please read the contrib-nodes readme https://flows.nodered.org/node/node-red-contrib-modbus
So when I have node.js v6.X I should install node-red-contrib-modbus v2.X ? Is that right?
Well personally I’d upgrade to Node-RED v0.20.x and therefore upgrade to nodejs v8 or v10 (first) and then install then correct version for that version of nodejs
Does someone know how to update Node-red on groov EPIC ?
Ask manufacturer)
Hi There, hope somebody can help me

Hi @fjungen, it appears you are using an unsupported version of node.js (13.5.0). That may, or may not, be the problem. But I suggest you first install a supported version (preferably 10.x or 12.x). You should then re-install node-red and go to your .node-red folder and run
npm rebuild
to make sure everything already installed is rebuilt for the new version. Then try the serialport again.
If you have further problems please also tell us which version of node-red you are using and what operating system.
Thanks Colin, appreciate the fast response, below the versions I am using

As far as I remember (there’s been multiple topics about this, use the forum search sorted on most recent) this specific node is currently unmaintained and doesn’t support any version above nodejs 8.
Thanks guys, downgrading to v12.14.0 worked !!
Good afternoom, I want know if i can use two node modbus read in a the same flow with ModbuSim.
Welcome to the forum @oscarpedraza85
If ModbuSim is a modbus server simulator then the modbus nodes should work with it ok just as with a real modbus device.
