ADS device identification
The unique identification of ADS devices is implemented with the aid of two identifiers:
- PortNr
- NetId
AMS ports
ADS devices in a TwinCAT message router are uniquely identified by a number, called the ADS port no. This is specified and fixed for ADS devices, whereas pure ADS client applications (e.g. a HMI system) are allocated a variable port number when they first access the message router.
The following AMS port numbers are already assigned:

AMS NetId
Each TwinCAT device in the network is identified by the AMS NetId. The AMS NetId consists of six octets. The first four octets can be freely selected. The last two octets (usually .1.1) serve as subnet mask for fieldbuses or further devices. The AMS NetId must be unique for all communication partners.
Configuration:
The AMS NetId of a local or remote TwinCAT device can be set in SYSTEM\Routes\NetId Management of a TC3 project.
Alternatively, the AMS NetId can be configured locally via the Router category in the TwinCAT SysTray menu. The device must be restarted after changing the AMS NetId.
