Tab ‘EtherCAT Slave - FMMU/Sync’¶
Object: EtherCAT slave
The tab shows the FMMUs and Sync Manager of the EtherCAT slave as they are defined in the device description file. There is a possibility to edit the FMMUs and Sync Manager, e.g. for the configuration of slave-to-slave communication.
Requirement: The auto-configuration mode in the EtherCAT master is deactivated.
Note
Note that these are expert settings which are not usually required for standard applications!
| Table shows the Fieldbus Memory Management Units of the slave, which are used for handling the process data. In each case the allocation of the logical address (GlobalStartAdr) to a physical address (PhysStartAdr) is defined. Mapping bit by bit is possible. | |
