Creating an Beckhoff ADS Connection

Configuration
1

I am pretty new to HA. I would like to make an ads connection (Beckhoff v2) to a remote CX1000. With laptop it is approachable.

  1. I’ve modified the configuration.yaml but it keeps not giving a connection? #############################################################

BECKHOFF (V2)

#############################################################
ads:
device: “5.0.113.102.1.1” #AMS NetId Beckhoff CX1000
ip_address: 192.168.2.12 #IP Address Beckhoff CX1000
port: 801 #TwinCAT v2 used

Example configuration.yaml entry

sensor:

  • platform: ads
    adsvar: ‘Unit_00._00QT03.iwDataIN_L2’
    unit_of_measurement: “kW”
    adstype: int
    name: ‘Power’

  1. When I want to install pyads in the terminal I get:
    pip install pyads => bash: command not found

  2. I want to try to add the route in the route table but this also does not give the right results

  • add static (target) and static (remote route)
  • Route Name: HomeAssistant?
  • AmsnetID: Must i use IP address of PLC or HA (with .1.1)?
  • IP Address: Must i use IP address of PLC or HA?

I am running out of options

regards

Make sure your formatting and indenting is correct:

ads:
  device: “5.0.113.102.1.1” #AMS NetId Beckhoff CX1000
  ip_address: "192.168.2.12" #IP Address Beckhoff CX1000
  port: 801 #TwinCAT v2 used

Try this:

platform: ads
  adsvar: .Unit_00._00QT03.iwDataIN_L2
  unit_of_measurement: “kW”
  adstype: int
  name: ‘Power’

Make sure you intent correctly, add a [period] before the adsvar name [assuming it is a global variable, if not put the POU name first e.g. MAIN.Unit_00.QT03.iwDataIN_L2] and remove the [single quotes] from adsvar name.

ADS was broken last summer but it might be fixed now. Let me know if this helps.

Careful: because you copied the unformatted text from above, you’ve pulled in some of the “smart quotes”. Fixed:

ads:
  device: "5.0.113.102.1.1"
  ip_address: "192.168.2.12"
  port: 801

platform: ads
  adsvar: .Unit_00._00QT03.iwDataIN_L2
  unit_of_measurement: "kW"
  adstype: int
  name: 'Power'

@Hommelte — that’s why is it so important to correctly format you code for the forum. The quickest and easiest way to do that is to surround it with three backticks like this:

```
CODE GOES HERE
```

which becomes:

CODE GOES HERE

That preserves spacing, indentation, quote characters etc.

@Troon thanks for the feedback. When you say “smart quotes”, are you referring to the comments (e.g.#AMS NetId Beckhoff CX1000)?

I have never tried commenting in the same line after the actual code but I assumed that it worked. Are you saying that commenting in that way will not work? That is really good to know for future reference. Thanks!

Look very carefully at the quotes around the kW in the unit_of_measurement lines in @zimbrich’s post and mine:

unit_of_measurement: “kW”
unit_of_measurement: "kW"

See the difference? The forum has changed the straight quotes into 66-99 style quotes because you didn’t format your original post as code. @zimbrich then copy-pasted those and then formatted as code, but the damage had been done by then.

The smart 66-99 quotes won’t work in templates or YAML config.

Unfortunately, still nothing. Very frustrating

Do you mean like this with the …???

Have tried all sorts of things with ’ and " but no success. Shouldn’t a route or something like that be created in the Beckhoff?

Hello,
I would like to join you here.
I have exactly the same problem and am stuck in the same place. I have defined the route in the Beckhoff controller. But how does Home Assistant know which NetID it has itself and which NetID the remote station (TwinCat) has?
Hopefully someone here can explain the configuration (where and how) of Home Assistant/pyADS and post it???
Thank you very much
Best regards

Maybe this will help you: (I use twincat 3 and didn’t get it working either)
Twincat 2 uses the 801 port and twincat 3 uses the 851

on the plc side you should add the route as well.
IP address of home-assistant for example 192.168.1.44. AmsNetId is then 192.168.1.44.1.1 (so you add .1.1 after the ip address of home-assistant)

Sorry for replying to an old topic, but I have the same question, I have a Beckhoff PLC with TwinCat 2 software, which is configured using the “TwinCat PLC control” software running on the PLC itself.
I previously used MQTT as an interface between Beckhoff and HA, but the implementation of MQTT in TwinCat2 is poorly written and buggy, which is why I would like to use ADS…

[EDIT]:
I have now configured the ADS protocol by adding an ADS Route in the TwinCat System Manger (NetID of HA was 192.168.0.177.1.1, based on the IP of my HA), this brought the network interface of the PLC down but after restarting, I only had read access to the PLC variables and could not write any of them.
How can I configure the PLC to allow write access?
