Error Code 0x0015

Meaning

Invalid mailbox configuration

Description

Mailbox communication (= acyclic parameter exchange) is done via two memory areas on the EtherCAT Slave Controller (ESC) – the “Output Mailbox” (master -> slave) and the “Input Mailbox” (slave-> master). Those memory areas are protected by SyncManagers to prevent from simultaneous access from master and salve controller at the same time. SyncManagers are hardware entities on the ESC. They are configured via certain registers in the ESC register area (starting at 0x0800). The configuration includes start address, length, and direction (output or input). If those settings differ from those expected by the host controller of the slave this error is returned
