no connection to Beckhoff PLC Simulation #25

dev4iotatgps · 2023-06-14T10:52:17Z

Hi,

I have following problem with the ads-client in node-red (v3.0.2). I use an Advantech IoT Router ICR3231W with Node-Red installed. I have also installed the node-red-contrib-ads and the node-red-contrib-ads-client. My Beckhoff TwinCAT 3.1.0.0 (EventLoggerVersion: 4024.47) is installed on a Windows 10x64 Lenovo Notebook. Router and Notebook is connected via a Netgear unmanaged switch. Firewall is disabled on both sides. At the TwinCAT ADS Router I have configured a route to my Node-Red

With the node-red-contrib-ads lib it was possible to get a connection to the PLC via the ADS System node. I was also able to read global variables from the PLC Simulation. I have configured the node as followed:

With the node-red-contrib-ads-client I am not able to get a connection to the PLC SIM. I use the ADS - Connection Status node.

Why is it working with the node-red-contrib-ads but not with the node-red-contrib-ads-client. When I started testing with the node-red-contrib-ads-client I have restarted the PLC Sim, restarted the Router where Node-Red is running on and deleted the configuration from the node-red-contrib-ads in Node-Red.

Thank you in advance!
Kind Regards,
Patrick

Are you sure that you only have one connection at time? Only one connection is supported if no TwinCAT router installed (so make sure the other ads library is not running at the same time and connecting to this target).

Can you set debugging level to 3 and post the console output?

dev4iotatgps · 2023-06-15T09:08:59Z

The other ads lib is not running and I have also removed the node configuration from the ads lib. After that, I have restarted the TwinCAT-System and the Router.

Here is the console output:

Hi Please get the ads-client logs from node-red console/logs. See: jisotalo/ads-client#99 (comment)

Thanks. Please try to set manual ADS port. Se set the localAdsPort to something like 31859 or so.

dev4iotatgps · 2023-06-21T09:56:55Z

With the localAdsPort it is not working:

Hi!

Are you absolute sure that the localAmsNetId and localAdsPort settings are saved?

Because from debug logs it seems that it's still trying to register a port from target.

There is _registerAdsPort(): Registering an ADS port from ADS router 192.168.2.3:48898 in the log but it's not followed by _registerAdsPort(): Local AmsNetId and ADS port manually given so using xxx (see https://github.com/jisotalo/ads-client/blob/d5a0fe33359974d3aee1d5634093d6a86d2de693/src/ads-client.js#L3692)

If they are saved and should be OK, then there might be a bug in this Node-RED library and the settings are not used.

dev4iotatgps · 2023-06-21T10:18:00Z

ok, now it is working! I have put the port wich you have mentioned above into the wrong field.. (localTcpPort)
Sorry! Thank you for your help!

What I do not understand is, when I leave the localAdsPort empty, there is also no localAmsNetId in the connection object, but I have set up a localAmsNetId

dev4iotatgps · 2023-06-21T10:20:54Z

This is the working config:

jisotalo · 2023-06-22T05:20:52Z

Glad to hear it's working! The reason you need to give these manually is that you don't have a AMS router running on your device.

The connection object should contain localAmsNetId and localAdsPort but in your picture it's not connected. They are set after successful connection if I remember right.
