EtherCAT scheduling
Real-time traffic should be assigned a documented task interval and port role. General plant messages must not be allowed to obscure the cycle budget reserved for coordinated devices.
ABB PM5680-2ETH 1SAP152000R0378 is an AC500 V3 high-performance processor with 160 MB of user program memory and 32 MB assigned to program code and data. Its 1 GHz class processing resources and 0.002 µs minimum instruction figure support control applications that combine fast logic with coordinated communication tasks.
ABB PM5680-2ETH 1SAP152000R0378 provides two Ethernet interfaces, including real-time EtherCAT capability, together with one configurable RS232/RS485 channel and a CAN interface. The integrated display and eight keys give the cabinet a local operating and diagnostic surface without replacing engineering-station records.
The modular arrangement of ABB PM5680-2ETH 1SAP152000R0378 depends on the selected TB56xx terminal base. The base supplies the Ethernet, serial, CAN and I/O-bus connection geometry, so the number of communication-module slots and the required network layout must be defined as part of the controller assembly.
