Ethernet X001 Interface
CX8090 57Version: 1.7
8.4 Real-time Ethernet
Real-time communication can take place only via ports X101 and X102.
See technical data: CX8090_TechnDataEthernet [}16]
RT-Ethernet for communication with further slaves such as the BK9100 can take place on the CX8090.
See CX8090_RT_Ethernet [}34] regarding this.
The EtherCAT Automation Protocol (EAP) is used for communication from controller to controller. Hence
Beckhoff controller such as CX or IPCs can exchange data with one another.
See CX8090 EAP [}35] regarding this.
8.5 ADS-Communication
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 communication with other PCs or devices is required, the ADS protocol can use TCP/IP as a
basis. Within a networked system it is thus possible to reach all data from any point.
The ADS protocol runs on top of the TCP/IP or UDP/IP protocols. It allows the user within the Beckhoff
system to use almost any connecting route to communicate with all the connected devices and to
parameterize them. Outside the Beckhoff system a variety of methods are available to exchange data with
other software tools.
Software interfaces
ADS-OCX
The ADS-OCX is an Active-X component. It offers a standard interface to, for instance, Visual Basic, Delphi,
etc.
