Comments
In addition to changing the ADS state and the device state, it is also possible to send data to the ADS server in order to transfer further information. For the current ADS devices (PLC, NC, ...) this data is not evaluated further.
Each ADS device can communicate its current state to other ADS devices. A distinction is made between the state of the device itself (DeviceState) and the state of the ADS interface of the ADS device (AdsState). The states that the ADS interface can adopt are laid down in the ADS specification.
