4.4.2.3 ADS
In order to be able to read and write attributes during the running time (e.g. from the PLC), the Box (e.g.
Bus Coupler) can be allocated via an ADS port. The ADS Port can be used to read / write attributes via
ADS read requests / ADS write requests:
The ADS IndexGroup contains the ClassId and the ADS IndexOffset contains InstanceId and AttributeId
(InstanceId * 256 + AttributeId).
The following ADS-Commands are used to exchange DeviceNet Explicit-Messages:
