ADS Communication

Overview

The ADS protocol (ADS: Automation Device Specification) is a transport layer within the TwinCAT system. It was developed for data exchange between the different software modules, for instance the communication between the NC and the PLC. This protocol enables communication with other tools from any point within the TwinCAT. If it is necessary to communicate with another PC or device, the ADS protocol is used on top of TCP/IP. Within a networked system it is thus possible to reach all data from any point.

In plain language, ADS is the communication protocol that piggybacks off of Ethernet IP. ADS holds a table of AMS Net ID Addresses and corresponding Ethernet IP addresses. You target your system with the appropriate AMS Net ID and you target looks up the associated Ethernet IP address to establish the communications.
