SubDeviceDiagnostics Class

Default constructor.

The number of times the SubDevice autonomously transitions to a lower state without a request from the MainDevice.

The value of AL Control register 0x0120.

The value of AL Status register 0x0130.

The value of AL Status Code register 0x0134.

The number of cycles the datagram, which is responsible for processing data exchange of the SubDevice, is received with an invalid working counter.

The device type retrieved from the register 0x1000 of the SubDevice.

The value of DL Status register 0x0110.

The fixed address of the SubDevice, which is set by the MainDevice during startup. Values start at 1001 and follow the connection order.

Additional topology information about a SubDevice.

The array that contains the Ethernet frame error count for each port.

The value of register 0x0101 of the SubDevice.

The actual link status on each port of the SubDevice.

The expected physical link on ports 1, 2, and 3 of a SubDevice. The processing order is port 0 → 3 → 1 → 2.

The EtherCAT link status of the SubDevice.

The array that contains the lost link count for each port. EtherCAT SubDevices increment a lost link counter upon a physical link loss with neighboring SubDevices.

The size of a SubDevice’s input mailbox buffer.

The size of a SubDevice’s output mailbox buffer.

The SubDevice name.

The number of times the MainDevice loses the physical link with a SubDevice.

The array that contains the physical layer communication error count for each port.

The array containing the fixed address of the device that is expected to be connected to each port.

The SubDevice's product code.

The SubDevice's revision number.

The SubDevice's serial number.

The alias address stored in the SubDevice EEPROM and can be written by the MainDevice. This address persists after power-off, allowing it to be used to differentiate identical SubDevices.

The SubDevice's device type.
