Tab: 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 an option to edit the FMMUs and Sync Manager (for example, for the configuration of slave-to-slave communication).

Requirement: The auto-configuration mode in the EtherCAT Master is disabled.

Note that these are expert settings which are not usually required for standard applications.

Table 433: FMMU
The 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 (“Phys. start address”) is defined. Bit-by-bit mapping is possible.

Table 435: Sync Manager
Display and editing of the synchronization manager of the slave. The physical start address, the type of access, the buffer, and the physical address to which the interrupts are to be sent (as well as others) are defined for each available Sync Manager type (mailbox in, mailbox out, inputs, outputs).
