AES for decentralized fieldbus connection

Controls up to 64 valves: AES for decentralized fieldbus connection

Decentralized fieldbus connection AES for Rexroth's pneumatic AV valve system

Shorter assembly times, increased modularization, and more flexibility for assembling variants: Rexroth's Advanced Electronic System (AES) meets these requirements for decentrally connecting pneumatic valves and machine peripheries to the fieldbus. The fieldbus electronics are optimized for use with the compact AV valve system but the system is also suitable as a stand-alone solution.

Rexroth's newly developed AES system is responsible for serial data exchange between the controller and the pneumatic valves, as well as additional inputs or outputs. The machine manufacturers are thus saved the task of individually wiring valves and sensors to the control cabinet. OEMs can place the especially compact and light AV valve systems with AES very close to the pneumatic drives. Installers then connect the sensors and single valves which are mounted close by to the decentralized I/O modules using short sections of cable, enabling them to pre-assemble complete machine modules, including peripheries. During final assembly, the modules only need to be connected to the controller via the fieldbus.

AES supports common fieldbuses such as Profibus, CANopen, and DeviceNet, as well as the Ethernet-based protocols ProfiNet, EtherCat and EtherNet/IP. The sercos automation bus, as well as Powerlink, will follow.

Altogether, each AES fieldbus coupler controls up to ten analog and digital I/O modules as well as up to 64 valves with up to 128 solenoids. The modular design of the AES increases the machine manufacturer's flexibility to quickly implement different variants.

An online configurator makes it easier to configure complete AV valve systems with all the I/O modules required for the application. The user can reorder all I/O modules as catalog products and also connect them without tools later. This allows OEMs to quickly implement customer-specific requests and, for example, integrate additional sensors for process monitoring. Furthermore, the modular AV valve system with AES reduces the complexity of logistics and warehousing: Users can combine existing and newly ordered components as required.
