EtherCAT.Slave.Driver.Default (ethercat v0.4.2)

Copy Markdown View Source

Fallback driver used when a slave is named without a specific hardware driver.

When used with process_data: {:all, domain_id}, this driver auto-discovers all PDOs declared in SII EEPROM and registers one signal per PDO. Signal names are derived from the PDO index: 0x1A00:pdo_0x1a00.

Raw bytes are passed through unchanged for both encode and decode, so read_input/2 returns a binary and write_output/2 accepts a binary.
