ADS Communication

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.
