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!

FMMU

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 (Global Start Address) to a physical address (Ph. Start Address) is defined. Mapping bit by bit is possible.
