ADS

The ADS (automation device specification) describes a device-independent and fieldbus independent interface for communication between Beckhoff automation devices running TwinCAT and other devices implementing this interface.

There is currently support for the following device types within Home Assistant:

Configuration

To enable ADS, add the following lines to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file. After changing the configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file, restart Home Assistant to apply the changes. The integration is now shown on the integrations page under Settings > Devices & services. Its entities are listed on the integration card itself and on the Entities tab.

# Example configuration.yaml entry
ads:
  device: "127.0.0.1.1.1"
  port: 801

Configuration Variables

Looking for your configuration file?
device string Required

The AMS NetId that identifies the device.

port integer Required

The port that runs the AMS server on the device, typically this would be 801 or 851.

ip_address string (Optional)

The IP address of the ADS device, if not set the first 4 bytes of the device id will be used.

Action

The ADS integration will register the write_by_name action allowing you to write a value to a variable on your ADS device.

{
    "adsvar": ".myvariable",
    "adstype": "int",
    "value": 123
}

Action parameters:

  • adsvar: Name of the variable on the ADS device. To access global variables on TwinCAT2 use a prepending dot .myvariable, for TwinCAT3 use GBL.myvariable.
  • adstype: Specify the type of the variable. Use one of the following: int, byte, uint, bool
  • value: The value that will be written in the variable.

Binary sensor

The ads binary sensor platform can be used to monitor a boolean value on your ADS device.

To use your ADS device, you first have to set up your ADS hub and then add the following to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file:

Sensor

The ads sensor platform allows reading the value of a numeric variable on your ADS device. The variable can be of type BOOL, BYTE, INT, UINT, SINT, USINT, DINT, UDINT, WORD, DWORD, REAL, or LREAL.

To use your ADS device, you first have to set up your ADS hub and then add the following to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file:

# Example configuration.yaml entry
sensor:
  - platform: ads
    adsvar: GVL.temperature
    unit_of_measurement: "°C"
    adstype: int

Configuration Variables

Looking for your configuration file?
adsvar string Required

The name of the variable which you want to access.

adstype string (Optional, default: int)

The datatype of the ADS variable, possible values are bool, byte, int, uint, sint, usint, dint, udint, word, dword, real and lreal.

name string (Optional)

An identifier for the sensor.

factor integer (Optional, default: 1)

A factor that divides the stored value before displaying in Home Assistant.

The factor can be used to implement fixed decimals. E.g., set factor to 100 if you want to display a fixed decimal value with two decimals. A variable value of 123 will be displayed as 1.23.

Switch
